Which of the following is a typical characteristic of debit cards? (1 point)
O Your bank may charge you a very large fee each time you use one.
O When you buy something from a store, you may be offered a discount if you open one with the store.
O They usually charge a lower interest rate than credit cards.
They are tied directly to your bank account.

Answers

Answer 1

A typical characteristic of debit cards is expressed by option D, they are tied directly to your bank account, since money has to be deducted for a purchase to be made.

How debit cards function

When you use a debit card to make a purchase, the money is deducted directly from your bank account. Debit cards do not typically charge interest like credit cards do, so C is not correct.

A is also not correct since most banks do not charge a fee for using a debit card, although some may charge fees for using an out-of-network ATM or overdraft fees if you spend more than you have in your account. B is not a typical characteristic of debit cards either, as there is generally no connection between a store's loyalty program or discounts and using a debit card for payment.

Therefore, it is possible to conclude that debit cards have option D as their characteristic. Since they require money in the bank to make the purchase, they are connected to one's account.

Warren wants to buy grass seed to cover his whole lawn, except for the pool. the pool is 5 3/4m by 3 1/2m. find the area the grass seed needs to cover
find the area the grass seed needs to cover

Answers

Grass Seed Area = L - 20 1/8

To help Warren determine the area of his lawn where grass seed is needed, we first need to know the total area of his lawn.

Unfortunately, you have not provided the dimensions of the entire lawn. However, I can guide you through the process using the information given about the pool.

First, let's find the area of the pool. The dimensions are 5 3/4m by 3 1/2m. To find the area, multiply the length by the width:
Area = (5 3/4) * (3 1/2)
Convert the mixed numbers to improper fractions:
Area = (23/4) * (7/2)
Multiply the fractions:
Area = (23*7) / (4*2) = 161/8

Now convert the improper fraction back to a mixed number:
Area = 20 1/8 square meters
This is the area of the pool. To find the area where grass seed is needed, subtract the pool's area from the total area of the lawn. Assuming the total area of the lawn is "L" square meters, the area to be covered with grass seed would be:
Grass Seed Area = L - 20 1/8

Once you provide the dimensions of the entire lawn, you can follow these steps to find the area where grass seed is needed.

How many terms are to be considered in the series with first term - 3 and common ratio r = -4 for the sum to exceed 1507​

Answers

,Based on the information, we need to consider 5 terms in the series for the sum to exceed 1507.

How to explain the series

Substituting the given values, we get:

1507 < -3(1 - (-4)^n)/(1 - (-4))

Simplifying this inequality, we get:

-4^n < 502

Taking the logarithm of both sides, we get:

n*log(4) > log(502)

n > log(502)/log(4)

n > 4.29

n = 5

write an equation of the line that passes through each pair of points (5, 7), (-8, -4)

Answers

Answer:

y = 11x/13 + 36/13

Step-by-step explanation:

We can write the line using y = mx + b form.

To find the slope, m, we can use the formula (y1 - y2) / (x1 - x2):

(7-(-4)) / (5-(-8)) = (7+4) / (5+8) = 11 / 13.

To find b, we can plug in one of the points. Lets use (5, 7).

y = 11/13 * x + b

7 = 11/13 * 5 + b

7 - 55/13 = b

b = 91/13 - 55/13 = (91-55)/13 = 36/13.

Your equation is:

y = 11x/13 + 36/13.

Answer: y = [tex]\frac{11}{13}[/tex]x + [tex]\frac{36}{13}[/tex]

Step-by-step explanation:

First, we will find the slope.

       [tex]m=\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{-4-7}{-8-5} =\frac{-11}{-13} =\frac{11}{13}[/tex]

Next, we will substitute this slope and a given point in and solve for our y-intercept (b).

       y = [tex]\frac{11}{13}[/tex]x + b

       (7) = [tex]\frac{11}{13}[/tex](5) + b

       (7) = [tex]\frac{11}{13}[/tex](5) + b

       7 = [tex]\frac{55}{13}[/tex] + b

       b = 7 - [tex]\frac{55}{13}[/tex]

       b = [tex]\frac{36}{13}[/tex]

Final equation:

       y = mx + b

     y = [tex]\frac{11}{13}[/tex]x + [tex]\frac{36}{13}[/tex]

Lucas takes lessons to learn how to play merengue music on his guitar he rides the bus to each lesson and then walks home he attends lessons and each lesson cost $13 which expression represents the total cost for Lucas to attend the lessons if each bus ride costs X dollars.

Answers

The expression that represents the total cost for Lucas to attend the lessons if each bus ride costs X dollars is:13n + Xn = (13+X)n

What do you mean by Cost ?

Cost is the most significant factor to determine success when you are operating a business. You need to understand different cost factors and how it affects profitability. We define costs as the value of money required to produce a product or deliver goods. In this section, we have explained different cost definitions.

If each lesson costs $13 and Lucas attends "n" lessons, then the total cost for the lessons will be 13n dollars.

Now, let's consider the cost of the bus rides. Lucas takes the bus to each lesson, so he takes "n" bus rides in total. If each bus ride costs X dollars, then the total cost of the bus rides will be Xn dollars.

Finally, Lucas walks home after each lesson, so there is no cost associated with walking.

Therefore, the expression that represents the total cost for Lucas to attend the lessons if each bus ride costs X dollars is:

13n + Xn = (13+X)n

So If each lesson costs $13 and Lucas attends "n" lessons, then the total cost for the lessons will be 13n dollars.

Now, let's consider the cost of the bus rides. Lucas takes the bus to each lesson, so he takes "n" bus rides in total. If each bus ride costs X dollars, then the total cost of the bus rides will be Xn dollars.

Finally, Lucas walks home after each lesson, so there is no cost associated with walking.

Therefore, the expression that represents the total cost for Lucas to attend the lessons if each bus ride costs X dollars is:

13n + Xn = (13+X)n

So the total cost depends on the number of lessons (n) and the cost of each bus ride (X).

The marginal cost function for a company is given by C'(q) = [tex]q^2[/tex] - 17q + 70 dollars/unit; where q is the quantity produced. If C(0) = 650, then total cost of producing 20 units = 2,600 dollars. Fixed cost for the quantity = 650 dollars. Variable Cost of producing 20 units = 1,950 dollars

To find the total cost function C(q), integrate the marginal cost function C'(q):

C(q) = ∫[tex](q^2 - 17q + 70)[/tex] dq = [tex](1/3)q^3 - (17/2)q^2 + 70q + K[/tex]

To find the constant K, use the given information: C(0) = 650

650 = [tex](1/3)(0)^3 - (17/2)(0)^2 + 70(0) + K[/tex]
K = 650

So the total cost function is:

C(q) = [tex](1/3)q^3 - (17/2)q^2 + 70q + 650[/tex]

Now, we find the total cost of producing 20 units:

C(20) = [tex](1/3)(20)^3 - (17/2)(20)^2 + 70(20) + 650[/tex]
C(20) = 2,600

Total cost of producing 20 units = 2,600 dollars.

Fixed cost is the cost incurred when producing 0 units, which is given as C(0) = 650 dollars.

To find the total variable cost for producing 20 units, subtract the fixed cost from the total cost:

Variable Cost = Total Cost - Fixed Cost
Variable Cost = 2,600 - 650
Variable Cost = 1,950 dollars

To summarize:
Fixed cost = 650 dollars
Variable cost of producing 20 units = 1,950 dollars
Total cost of producing 20 units = 2,600 dollars

Determine whether the function is an example of exponential growth or exponential decay then find the y-intercept y=8 (2/7)^x

Answers

This function is an example of exponential decay because the base of the exponential term (2/7) is between 0 and 1. and the y-intercept is 8.

To find the y-intercept, we need to evaluate the function when x=0, which gives:

y = 8 (2/7)^0 = 8

The given function is an example of exponential decay. In an exponential function, if the base of the exponent is between 0 and 1, the function shows exponential decay, and if it is greater than 1, the function shows exponential growth.

In the given function y = 8 (2/7)^x, the base of the exponent is 2/7, which is less than 1. This means that as the value of x increases, the value of the function decreases at a decreasing rate, which is the characteristic of exponential decay.

To find the y-intercept of the function, we can substitute x=0 in the given function. When x=0, we have:

y = 8 (2/7)^0

y = 8 x 1

y = 8

This means that the y-intercept of the function is (0, 8), which is the point where the function intersects the y-axis. In this case, it represents the initial value of the function when x=0.

Therefore, This function is an example of exponential decay because the base of the exponential term (2/7) is between 0 and 1. and the y-intercept is 8.

what is the trignometry?

One of the most significant areas of mathematics, trigonometry has a wide range of applications. T

he study of the relationship between the sides and angles of the right-angle triangle is essentially the focus of the field of mathematics known as "trigonometry."

Hence, employing trigonometric formulas, functions, or trigonometric identities can be helpful in determining the missing or unknown angles or sides of a right triangle.

Angles in trigonometry can be expressed as either degrees or radians. 0°, 30°, 45°, 60°, and 90° are some of the trigonometric angles that are most frequently employed in computations.

We can use the half-angle formula for tangent to show that:

tan(15°) = tan(30°/2) = (1 - cos(30°)) / sin(30°)

We know that cos(30°) = √3/2 and sin(30°) = 1/2, so we can substitute those values in:

tan(15°) = (1 - √3/2) / 1/2

Simplifying the denominator and multiplying by the reciprocal:

tan(15°) = 2(1 - √3/2)

Simplifying the expression:

Answers

Gabriela will use 1620 square inches of wood to build the open box.

The amount of wood Gabriela will use depends on the surface area of the box, which is the sum of the areas of its six faces. Since the box is open on top, it will have five faces: four sides and a bottom.

The area of the bottom is the area of a rectangle with length 18 in. and width 15 in., which is:

Area of bottom = length x width = 18 in. x 15 in. = 270 in²

The area of each side is the product of the height and the length of the corresponding base, which is:

Area of each side = height x length = 15 in. x 18 in. = 270 in²

So the total surface area of the box is:

Total surface area = 2 x (Area of bottom) + 4 x (Area of each side)

Answers

Answer:

Step-by-step explanation:

To test if there exists a significant decrease in the popularity vote percentage of the politician, we can conduct a hypothesis test using the significance level of 0.10.

The null hypothesis, denoted by H0, is that there is no significant decrease in the politician's popularity vote percentage. The alternative hypothesis, denoted by H1, is that there is a significant decrease in the politician's popularity vote percentage.

We can use the sample proportion of supporters, which is 405/820 = 0.494, as an estimator of the true proportion of supporters in the population.

Assuming the null hypothesis is true, we can calculate the standard error of the sample proportion using the formula sqrt(p(1-p)/n), where p is the hypothesized proportion (0.55) and n is the sample size (820). This gives us a standard error of sqrt(0.55*0.45/820) = 0.024.

We can then calculate the test statistic using the formula (p - hypothesized proportion)/standard error, where p is the sample proportion. This gives us a test statistic of (0.494 - 0.55)/0.024 = -2.333.

With a significance level of 0.10 and a two-tailed test, the critical values for the test statistic are -1.645 and 1.645. Since the calculated test statistic (-2.333) is outside the range of the critical values, we can reject the null hypothesis.

Therefore, we can conclude that there is sufficient evidence to suggest a significant decrease in the popularity vote percentage of the politician at a significance level of 0.10.

For the given vectors u and v, (a) 6u =  (24, 30). (b) 6u+4v =  (40, 30).      (c) v-4u =  (-12, -20).

Given vectors u and v.

a) To find 6u, we simply multiply each component of u by 6:

6u = 6(4, 5) = (6(4), 6(5)) = (24, 30)

Therefore, 6u = (24, 30).

b) To find 6u + 4v, we first need to find 4v by multiplying each component of v by 4:

4v = 4(4, 0) = (4(4), 4(0)) = (16, 0)

Next, we add 6u and 4v by adding the corresponding components:

6u + 4v = (24, 30) + (16, 0) = (24+16, 30+0) = (40, 30)

Therefore, 6u + 4v = (40, 30).

c) To find v - 4u, we first need to find 4u by multiplying each component of u by 4:

4u = 4(4, 5) = (4(4), 4(5)) = (16, 20)

Next, we subtract 4u from v by subtracting the corresponding components:

v - 4u = (4, 0) - (16, 20) = (4-16, 0-20) = (-12, -20)

verify that the equation is an identity. 2cosx2x/sin2x=cotx-tanx

Answers

The LHS is equal to the RHS, and the given equation is verified as an identity. We have to verify that the following equation is an identity:

2cos(x) 2x / sin2(x) = cot(x) - tan(x)

Starting from the left-hand side (LHS):

2cos(x) 2x / sin2(x) = 2cos(x) 2x / (1 - cos2(x)) (using the identity sin2(x) = 1 - cos2(x))

= 2cos(x) 2x / (1 - cos(x)) (1 + cos(x))

= 2cos(x) 2x / (1 - cos(x)) (1 + cos(x)) (multiplying the denominator by (1 + cos(x)))

= 2cos(x) 2x / (1 - cos2(x))

= 2cos(x) 2x / sin2(x) (using the identity 1 - cos2(x) = sin2(x))

= 2cos(x) / sin(x) (simplifying by canceling out the common factor of 2 and cos(x))

= 2cos(x) / sin(x) * (cos(x) / cos(x)) (multiplying by 1 in the form of cos(x)/cos(x))

= 2cos2(x) / (sin(x)cos(x))

= 2cos(x)/sin(x) * cos(x)

= cot(x) * cos(x)

Now, moving to the right-hand side (RHS):

cot(x) - tan(x) = cos(x)/sin(x) - sin(x)/cos(x)

= cos2(x)/sin(x)cos(x) - sin2(x)/sin(x)cos(x)

= (cos2(x) - sin2(x))/sin(x)cos(x)

= cos(x)/sin(x) * cos(x)/cos(x) - sin(x)/cos(x) * sin(x)/sin(x) (using the identity cos2(x) - sin2(x) = cos(x)cos(x) - sin(x)sin(x))

= cot(x) * cos(x)

Therefore, the LHS is equal to the RHS, and the given equation is verified as an identity.

The sales tax in your city is 7. 5%, and the license and title charges are $175. 13. What is the total purchase price of the car including tax, license, and title? Round your answer to the nearest cent. A. $24,949. 80 c. $27,722. 01 b. $24,967. 32 d. $27,735. 14.

Answers

Answer is 27,529.82
To calculate the total purchase price of the car including tax, license, and title, we need to add the down payment, the financed balance, the sales tax, and the license and title charges.

First, we calculate the down payment:
10% of $25,625 = $2,562.50

Next, we calculate the financed balance:
$25,625 - $2,562.50 = $23,062.50

Then, we calculate the sales tax:
7.5% of $23,062.50 = $1,729.69

Finally, we add the license and title charges:
$1,729.69 + $175.13 = $1,904.82

So the total purchase price of the car including tax, license, and title is:
$2,562.50 + $23,062.50 + $1,904.82 = $27,529.82

Rounded to the nearest cent, the answer is option D: $27,735.14.

Tim made his mother a quilt. The width is 6 5 /7 ft and the length is 7 3 /5 ft. What is the area of the quilt?

Answers

The quilt's area is approximately 60.74 square feet.

How to calculate the quilt's area?

To calculate the area of the quilt, we need to multiply the width by the length.

First, we need to convert the mixed numbers to improper fractions:

Width: 6 5/7 ft = (7 x 6 + 5)/7 = 47/7 ft

Length: 7 3/5 ft = (5 x 7 + 3)/5 = 38/5 ft

Now, we can multiply the width by the length:

Area = width x length

Area = (47/7) ft x (38/5) ft

Area = 2126/35 sq ft

Area ≈ 60.74 sq ft

Therefore, the area of the quilt is approximately 60.74 square feet.

Ellen mixed 1over 4 kg of flour with 2 over 9 kg of sugar. Determine a reasonable estimate for the amount of flour and sugar combined

Answers

A reasonable estimate for the amount of flour and sugar combined is approximately 0.36 kg.

To determine a reasonable estimate for the amount of flour and sugar combined, we first need to add the fractions 1/4 and 2/9. To do this, we need to find a common denominator. The least common multiple of 4 and 9 is 36. We can convert 1/4 to 9/36 by multiplying both the numerator and denominator by 9. We can also convert 2/9 to 4/36 by multiplying both the numerator and denominator by 4. Now we can add the fractions:

9/36 + 4/36 = 13/36

So Ellen mixed 13/36 kg of flour and sugar combined. To convert this to a decimal, we can divide the numerator by the denominator:

13 ÷ 36 ≈ 0.36

Therefore, a reasonable estimate for the amount of flour and sugar combined is approximately 0.36 kg.

Find the distance traveled by the top of second hand of a clock in 4 minute if the hand is 8 cm long

Answers

The second hand of a clock rotates once around the clock face in 60 seconds or one minute. Therefore, in 4 minutes, the second hand will rotate 4 times around the clock face.

The length of the second hand of a clock is 8 cm. The distance traveled by the top of the second hand in one full rotation is equal to the circumference of a circle with radius 8 cm, which is 2πr = 2π(8) = 16π cm.

The distance traveled by the top of the second hand in 4 rotations (or 4 minutes) is:

4 rotations * 16π cm/rotation = 64π cm

So the distance traveled by the top of the second hand of a clock in 4 minutes if the hand is 8 cm long is approximately 64π cm or about 201.06 cm (when rounded to two decimal places).

216 mm^2

Answers

Answer:

147 mm^2

Step-by-step explanation: The surface area has to be more, but not double the smaller figures surface area therefore the answer is 147 mm^2

The requried surface area of the larger solid is approximately 147 mm². Option A is correct.

What is surface area?

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Let's call the larger solid's surface area S.

Since the two solids are similar, their volumes have a ratio of (side length)³. Let's call the ratio of the side lengths of the larger to the smaller solid as k. Then:

[tex](k^3)(540 mm^3) = 857.5 mm^3[/tex]

Simplifying the above equation, we get:

[tex]k = (857.5/540)^{(1/3)}[/tex] =7/6

So, the larger solid is about 7/6=1.183 times bigger than the smaller solid in terms of side length. Since the surface area has a ratio of [tex](side length)^2[/tex], we can find the surface area of the larger solid by:

[tex]S = (1.183^2)(108 mm^2) \approx 147 mm^2[/tex]

Therefore, the surface area of the larger solid is approximately 147 mm². Answer: A.

a farmer made a loss of 28% by selling a gold for1440shillings what percentage profit would have made if he had sold the goat.for.sh 2100​

Answers

The farmer would have made a profit of 5% if he had sold the goat for 2100 shillings.

Let's use the given terms and find out the percentage profit if the farmer had sold the goat for 2100 shillings.
Calculate the cost price of the goat
We know that the farmer made a loss of 28% by selling the goat for 1440 shillings. Let's represent the cost price as "CP".

We can write the equation:
[tex]CP \times  (1 - loss% ) = selling price (SP)[/tex]
[tex]CP \times  (1 - 0.28) = 1440[/tex]
Solve for CP
[tex]CP \times 0.72 = 1440[/tex]
CP = 1440 / 0.72
CP = 2000 shillings
Calculate the percentage profit
Now we want to find out the percentage profit if the farmer had sold the goat for 2100 shillings.

We can write the equation:
[tex](SP_{new - CP)} / CP \times  100 = profit[/tex]
[tex](2100 - 2000) / 2000 \times  100 = profit%[/tex]
[tex]100 / 2000 \times  100 = profit%[/tex]
5% = profit%.
