Team A purchases 3 soccer balls and 7 basketballs for a total cost of $1240. Team B purchases 5 soccer balls and 10 basketballs for a cost of $1900. If team C purchases 4 soccer balls and 6 basketballs, how much would they expect to pay?

Answers

Answer 1

The total cost for team C would be $760 + $600 = $1360.

How to calculate  how much would they expect to pay

We can start by setting up a system of equations based on the given information. Let x be the cost of one soccer ball and y be the cost of one basketball. Then we have:

3x + 7y = 1240 (equation 1)

5x + 10y = 1900 (equation 2)

We can solve this system of equations by using either substitution or elimination method. Let's use elimination method here:

Multiplying equation 1 by 2 and subtracting it from equation 2, we get:

5x + 10y - (6x + 14y) = 1900 - 2(1240)

-x - 4y = 420

Now we can use either equation 1 or equation 2 to solve for x or y. Let's use equation 1:

3x + 7y = 1240

3x + 3y = 840 (multiplying both sides by -1 and adding to the previous equation)

4y = 400

y = 100

So one basketball costs $100. Now we can substitute this value back into either equation 1 or equation 2 to solve for x. Let's use equation 1:

3x + 7y = 1240

3x + 7(100) = 1240

3x = 570

x = 190

So one soccer ball costs $190.

Now we can use these values to find the cost for team C:

4 soccer balls cost 4 x $190 = $760

6 basketballs cost 6 x $100 = $600

So the total cost for team C would be $760 + $600 = $1360.

2n-2
N+12
4n+6

Answers

Answer: To find the length of the midsegment of a trapezoid, you need to add the lengths of the two bases together and divide by 2.

The length of the top base is 2n-2 and the length of the bottom base is 4n+6.

Adding the two bases together gives:

(2n-2) + (4n+6) = 6n + 4

Dividing by 2 gives:

(6n + 4) / 2 = 3n + 2

Therefore, the length of the midsegment of the trapezoid is 3n + 2.

A window in the shape of a parallelogram has a base of 36 inches, and a height of 45 inches. What is the area?

Answers

The area of a parallelogram is given by the formula:

$\sf\implies{\boxed{A = bh}}$

where $b$ is the length of the base and $h$ is the height.

In this case, the base is 36 inches and the height is 45 inches, so the area of the parallelogram is:

$\sf\implies\:A = bh = 36 \cdot 45 = 1620$

Therefore, the area of the parallelogram-shaped window is 1620 square inches.

A right rectangular prism has length 10 in. And width 8 in. The surface area of the prism is 376 in2. What equation can be used to find the height in inches?

Answers

The equation to find the height is 376 = 160 + 20h + 16h.

The height of the right rectangular prism is 6 inches.

We have,

Let's denote the height of the right rectangular prism as "h" inches.

The formula for the surface area of a right rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Given that the length (l) is 10 inches and the width (w) is 8 inches, and the surface area is 376 square inches, we can substitute these values into the formula:

376 = 2(10)(8) + 2(10)(h) + 2(8)(h)

Simplifying this equation:

376 = 160 + 20h + 16h

Combine like terms:

376 = 160 + 36h

Rearranging the equation to isolate "h":

36h = 376 - 160

36h = 216

Finally, divide both sides of the equation by 36 to solve for "h":

h = 216/36

h = 6

Therefore,

The height of the right rectangular prism is 6 inches.

A manufacturer makes aluminum cups with a volume of 10 cubic centimetres cach, in the form of right circular cylinders open at the top. Find the dimensions that would require the least amount of material.

Answers

The dimensions that require the least amount of material are r = (10/π)^(1/3) cm for the radius and h = (10/π)^(1/3) cm for the height.

To minimize the amount of material used for making aluminum cups with a volume of 10 cubic centimeters, you will need to optimize the dimensions of the right circular cylinders.

Given the volume (V) is 10 cm³, the formula for the volume of a right circular cylinder is V = πr²h, where r is the radius and h is the height.

10 = πr²h

To minimize the material used, we want to minimize the surface area (SA) of the open cylinder, which is given by the formula SA = 2πrh + πr² (the first term represents the lateral surface and the second term the base).

Using the volume formula, we can find a relationship between r and h:

h = 10 / (πr²)

Now substitute this expression for h in the surface area formula:

SA(r) = 2πr(10 / (πr²)) + πr²
SA(r) = 20/r + πr²

To find the minimum surface area, differentiate SA(r) with respect to r and set the result equal to zero:

d(SA)/dr = -20/r² + 2πr

Now solve for r:

0 = -20/r² + 2πr
20/r² = 2πr
r³ = 10/π

Now take the cube root of both sides:

r = (10/π)^(1/3)

To find the height, substitute this value of r back into the expression for h:

h = 10 / (π((10/π)^(1/3))²)
h = (10/π)^(1/3)

The dimensions that require the least amount of material are r = (10/π)^(1/3) cm for the radius and h = (10/π)^(1/3) cm for the height.

Pythagorean Theorem answer quick please

Answers

Answer:

3.9

Step-by-step explanation:

pythagorean theorem states:

[tex]a^{2} +b^{2} =c^{2}[/tex]

We know that a is the height of the triangle, 2.

We also know that b is the base of the triangle, 3.

So, solve for c:

2²+3²=c²

simplify

4+9=c²

15=c²

take the square root of both sides

c=3.9

So, the spider and the fly are 3.9 ft apart from each other

Hope this helps :)

Answer:

3.6 feet

Step-by-step explanation:

The Pythagorean theorem states that a^2+b^2=c^2, where c is the hypotenuse, or longest side of the triangle opposite to the right angle, and a and b are the two legs of the triangle (the other two sides.)

In the question, sides a and b are given as 2ft and 3ft long. Plugging 2 and 3 into the equation, we will get that 2^2+3^2=c^2. 2 x 2 = 4 and 3 x 3 = 9, so 4 + 9 = c^2, or, c^2 = 13.

However, this is still c^2, not c, so we must take the square root of both sides. This is because the equation is now essentially saying that c x c = 13, so if we find a number that when multiplied by itself equals 13, that number will be c. to do this, we must take the square root of 13. This will give us an irrational number- approximately 3.605551275. The question asks to round it to the nearest tenth though, so this will simply become 3.6.

In the context of this question, it means that the spider and the fly are 3.6ft apart.

Jason borrowed $5000 to go with the money he'd saved to buy a tractor. The finance charge on the loan was $55 and the term on the loan was 360 days. What was the APR for Jason's loan?
O 0. 011%
O 1. 116%
O 4. 015%
O 1. 527%​

Answers

The answer is option B: 1.116%.

To find the APR(Annual Percentage Rate) for Jason's loan, we first need to calculate the total amount of interest he paid.

The finance charge of $55 is the interest paid for the 360-day term.

To find the total interest, we can use the formula:

Total interest = (finance charge / loan amount) x (days in a year / loan term in days)

Plugging in the values, we get:

Total interest = (55 / 5000) x (365 / 360)

Total interest = 0.011 x 1.01389

Total interest = 0.01116 or 1.116%

Therefore, the APR for Jason's loan is 1.116%.

The probability of Karmen picking a car with a belge interior and an automatic transmission is

Answers

The probability of Karmen picking a car with a belge interior and an automatic transmission is 1/6

How to find the probability?

To find the probability, we need to start by identifying the event or situation for which we want to calculate the probability.

Since Karmen has three choices for the exterior color, two choices for the interior color, and two choices for the transmission, the total number of possible car configurations is:

3 x 2 x 2 = 12

This means there are 12 different cars to choose from.

To find the probability of picking a car that has a black exterior and a belge interior, we need to determine how many cars meet these criteria. There is only one car that has a black exterior and a belge interior, so the probability of picking this car is:

1/12

Therefore, the probability of Karmen picking a car with a black exterior and a belge interior is 1/12.

To find the probability of picking a car with a belge interior and an automatic transmission, we need to determine how many cars meet these criteria. There are two cars that have a belge interior and an automatic transmission, so the probability of picking one of these cars is:

A store has `80` pumpkins for sale. Here are the values of the quartiles. About how many of the `80` pumpkins would you expect to weigh less than `15.5` pounds

Answers

This is just a rough estimate, and the actual number of pumpkins that weigh less than 15.5 pounds could be slightly higher or lower.

What is the median?

The median is a measure of central tendency that represents the middle value in a dataset when the values are arranged in order of magnitude.

Assuming that the quartiles divide the pumpkins' weights into four equal parts, we can use the value of the second quartile (Q2) to estimate the median weight of the pumpkins. Since there are 80 pumpkins, Q2 would be the average of the 40th and 41st heaviest pumpkins.

We don't know the exact values of the quartiles, but we can make some reasonable assumptions. For example, if we assume that the first quartile (Q1) is around 12 pounds and the third quartile (Q3) is around 20 pounds, then we can estimate the median weight as follows:

Median = (Q2) = (Q1 + Q3)/2 = (12 + 20)/2 = 16 pounds

Based on this estimate, we can expect that roughly half of the 80 pumpkins (i.e., 40 pumpkins) weigh less than 16 pounds. Therefore, we might expect that slightly fewer than 40 pumpkins would weigh less than 15.5 pounds.

However, this is just a rough estimate, and the actual number of pumpkins that weigh less than 15.5 pounds could be slightly higher or lower depending on the distribution of the pumpkin weights.

Mrs.lane makes a 22% commission on commercial advertising sales for the local newspaper plus $8.25/hr. working 40hrs/week. her average bi-weekly commercial sales are $5,625. how much would her average gross monthly income be?​

Answers

Mrs. Lane's average gross monthly income would be $3,135.

How to find the income?

To find the monthly income of  Mrs. Lane's,

First, we need to find Mrs. Lane's commission for her bi-weekly commercial sales:

Commission = 22% of $5,625 = 0.22 x $5,625 = $1,237.50

Next, we need to find her hourly wage for a week:

Hourly wage = $8.25 x 40 = $330

Her gross bi-weekly income is the sum of her commission and hourly wage:

Gross bi-weekly income = Commission + Hourly wage

= $1,237.50 + $330

= $1,567.50

To find her gross monthly income, we can multiply her gross bi-weekly income by the number of bi-weekly pay periods in a month:

Gross monthly income = Gross bi-weekly income x Number of bi-weekly pay periods in a month

= $1,567.50 x 2

= $3,135

Therefore, Mrs. Lane's average gross monthly income would be $3,135.

Answers

the resulting 90% confidence interval for the average cost for healthcare of a senior citizen receiving Medicare  is [$12,000, $14,000].

The estimated average cost of providing healthcare for a senior citizen receiving Medicare is $13,000 per year, and the margin of error for this estimate is $1,000 with a 90% confidence level.

To find the confidence interval, we need to add and subtract the margin of error from the estimated mean.

Lower Limit = Estimated Mean - Margin of Error

Lower Limit = 13,000 - 1,000

Lower Limit = 12,000

Upper Limit = Estimated Mean + Margin of Error

Upper Limit = 13,000 + 1,000

Upper Limit = 14,000

Therefore, the resulting 90% confidence interval for the average cost for healthcare of a senior citizen receiving Medicare is [$12,000, $14,000]. This means we are 90% confident that the true mean cost of providing healthcare for a senior citizen receiving Medicare is between $12,000 and $14,000 per year.

78/100 is 78% (because percent literally means "per hundred)

Another way is to just divide. 39/50 means 39 ÷ 50.

39 ÷ 50 is .78 then times by 100 to change to a percent. This works for all kinds of fractions.

Ryann is filing Chapter 7 bankruptcy. She will be able to include $10,148.22 of her total debt of $112,758.00Calculate what percent of Ryann's total debt is included in the bankrup

Answers

Answer:

Step-by-step explanation:

To calculate the percentage of Ryann’s total debt that is included in the bankruptcy, you can divide the amount of debt included in the bankruptcy by the total debt and then multiply by 100.

So, the calculation would be: ($10,148.22 / $112,758.00) * 100 = 9%.

This means that 9% of Ryann’s total debt is included in the bankruptcy.

D is the centroid of PQR PA= equals 17 BD equals nine and DQ equals 14 find each missing measure

Answers

The centroid of the triangle is D and the measures of sides are solved

Given data ,

Let the triangle be represented as ΔPQR

Now , the centroid of the triangle is D

where the measure of PA = 17 units

The measure of BD = 9 units

And , the measure of side DQ = 14 units

Now , centroid of a triangle is formed when three medians of a triangle intersect

And , from the properties of centroid of triangle , we get

PA = AR

DR = DQ

AD = BD

On simplifying , we get

The measure of side AR = 17 units

PR = PA + AR = 34 units

The measure of side DR = 14 units

BR = BD + DR = 23 units

The measure of side AD = 9 units

AQ = AD + DQ = 23 units

Hence , the centroid is solved

Elena is trying to figure out how many movies she can download to her hard


drive. The hard drive is supposed to hold 500 gigabytes of data, but 58


gigabytes are already taken up by other files. Each movie is 8 gigabytes. Elena


wrote the inequality 8x + 58 ≥ 500 and solved it to find the solution x ≥ 55. 25.



4a) Explain how you know Elena made a mistake based on her solution.



4b) Fix Elena's inequality and explain what each part of the inequality represent.

Answers

Based on Elena's solution, x represents the number of movies that can be downloaded. However, her inequality is incorrect as it states that the total amount of downloaded data (8x + 58) is greater than or equal to the total capacity of the hard drive (500 gigabytes).

This means that Elena is considering the amount of data taken up by other files in addition to the movies she wants to download. Therefore, her solution of x ≥ 55.25 is incorrect as it would allow Elena to download more movies than the remaining capacity of the hard drive.

The corrected inequality should be 8x ≤ 442, as the remaining capacity of the hard drive is 500 - 58 = 442 gigabytes. This means that Elena can download a maximum of 55 movies (8 x 55 = 440), leaving 2 gigabytes of space remaining on the hard drive. Therefore, each part of the inequality represents the total amount of data used by the movies downloaded (8x) and the remaining capacity of the hard drive (442).

f(x,y) = x2 + y² + xy {(x, y) : x2 + y2 < 1}
"Find the maxima and minima, and where they are reached, of the
following function. Find the locals and absolutes. Identify the
critical points inside the disk if any."

Answers

The given function f(x,y) = x^2 + y^2 + xy has a maximum value of 3/4 at (x,y) = (1/2,1/2) and a minimum value of -1/4 at (x,y) = (-1/2,1/2) inside the disk x^2 + y^2 < 1. There are no critical points inside the disk.

To find the critical points, we need to take partial derivatives of the function with respect to x and y and solve the resulting equations simultaneously.

fx = 2x + y = 0

fy = 2y + x = 0

Solving these equations, we get the critical point at (x,y) = (-1/2,-1/2) outside the disk. Hence, we do not consider it further.

Next, we need to find the boundary points of the disk, which is the circle x^2 + y^2 = 1. We can parameterize this circle as x = cos(t) and y = sin(t), where t ranges from 0 to 2π.

Substituting these values in the given function, we get:

f(cos(t), sin(t)) = cos^2(t) + sin^2(t) + cos(t)sin(t)

= 1/2 + 1/2sin(2t)

Now, we need to find the maximum and minimum values of this function. Since sin(2t) ranges from -1 to 1, the maximum value of the function is 3/4 when sin(2t) = 1, i.e., when t = π/4 or 5π/4. At these points, x = cos(π/4) = 1/2 and y = sin(π/4) = 1/2.

Similarly, the minimum value of the function is -1/4 when sin(2t) = -1, i.e., when t = 3π/4 or 7π/4. At these points, x = cos(3π/4) = -1/2 and y = sin(3π/4) = 1/2.

Therefore, the function has a maximum value of 3/4 at (x,y) = (1/2,1/2) and a minimum value of -1/4 at (x,y) = (-1/2,1/2) inside the disk x^2 + y^2 < 1. There are no critical points inside the disk.
