GAMES- two friends are playing a game with a 20 sided dye that has all of the letters of the alphabet except Q U V X Y and Z. What is the probabilty that the dye will land on a vowel?

Answers

Answer 1

The probability of the die landing on a vowel is 1 in 5, or 20%.

In this game, the 20-sided die has the letters A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, R, S, T, and W. To calculate the probability of the die landing on a vowel, we need to identify the vowels present on the die and then determine the probability.

The vowels on this die are A, E, I, and O. There are 4 vowels out of the 20 possible outcomes, so the probability of landing on a vowel can be calculated by dividing the number of successful outcomes (vowels) by the total number of possible outcomes (20 sides).

Probability = (Number of Vowels) / (Total Sides)
Probability = 4 / 20

Now, simplify the fraction:

Probability = 1 / 5

The probability of the die landing on a vowel is 1 in 5, or 20%.

Solids with curves (such as cylinders) cannot be laid out as a net.

Answers

Answer:

Step-by-step explanation:

False.

Solids with curves can be laid out as a net. In fact, there are many solids with curves that can be represented by a net. For example, a cylinder can be represented by a net consisting of two circles for the top and bottom faces and a rectangle wrapping around the circumference of the circles for the side face. Similarly, a cone can be represented by a net consisting of a circle for the base and a sector of a circle for the lateral face, which can be unfolded and attached to the circular base.

While it may be more difficult to visualize and create a net for a solid with curves compared to a solid with flat faces, it is still possible to do so in many cases.

What is the volume of a can with a diameter of 4 inches and a height of 9 inches


and what is the surface area of a can with a diameter of 4 inches and height of 9 inches



and ratio of surface area to volume

Answers

The volume of the can is 36π cubic inches, the surface area is 44π square inches, and the ratio of surface area to volume is 11/9.

To find the volume and surface area of a can with a diameter of 4 inches and a height of 9 inches, you can follow these steps:

1. Calculate the radius, Since the diameter is 4 inches, the radius (r) is half of that, which is 2 inches.

2. Find the volume, The formula for the volume (V) of a cylinder is V = πr^2h, where r is the radius and h is the height. In this case, V = π(2^2)(9) = 36π cubic inches.

3. Calculate the surface area, The formula for the surface area (A) of a cylinder is A = 2πrh + 2πr^2. Here, A = 2π(2)(9) + 2π(2^2) = 36π + 8π = 44π square inches.

4. Determine the ratio of surface area to volume, To find this ratio, divide the surface area by the volume. In this case, the ratio is (44π)/(36π). The π's cancel out, and the ratio simplifies to 44/36, which further simplifies to 11/9.

So, the volume of the can is 36π cubic inches, the surface area is 44π square inches, and the ratio of surface area to volume is 11/9.

Using circle theorems  the angles in triangle ΔABM are

∠BMA = 30°∠BAM = 30° and∠ABM = 120°

What are circle theorems?

Circle theorems are theorems that govern circle peoperties

To find the angles in triangle ABM, we notice that in ΔABO, since OB = OA (radius of the circle), then ΔABO is an isoceles triangle.

So, ∠OAB = ∠ABO  (Base angles of an isoceles triangle)

Now, ∠OAB = ∠ABO = ∠A = 30°

Also ∠OAB + ∠ABO = ∠BOM (sum of opposite interior angles)

30° +  30° = ∠BOM

∠BOM = 60°

Now since OB is the radius and touches MV at B, and thus perpendicular to it. so, ∠OBM = 90°

Now, ∠OAB + ∠OBM = ∠ABM

30° + 90° = ∠ABM

∠ABM = 120°

Now in triangle ΔABM

∠BAM + ∠ABM + ∠BMA = 180° (sum of angles in a triangle)

Now

∠BAM = ∠OAB = 30°, ∠ABM = 120°

So, making ∠BMA subject of the formula, we have that

∠BMA = 180° - ∠BAM + ∠ABM

So, substituting the values of the variables into the equation, we have that

∠BMA = 180° - ∠BAM + ∠ABM

∠BMA = 180° - 30° - 120°

∠BMA = 180° - 150°

∠BMA = 30°

So, the angles are

∠BMA = 30°∠BAM = 30° and∠ABM = 120°

Circle Q has a diameter AB. If the distinct point C is also on the circle then triangle ABC must be

Answers

If point C is on the circle with diameter AB, then triangle ABC must be a right triangle. This is because the diameter of a circle is the longest chord and it passes through the center of the circle.

If we draw a line from point C to the center of the circle (which is the midpoint of AB), we get a perpendicular bisector of AB, meaning that it cuts AB into two equal parts and forms right angles with it. This also means that AC and BC are equal in length (since they both form radii of the circle), and the angle at point C must be a right angle (since it forms a straight line with the center of the circle). Thus, triangle ABC satisfies the criteria for a right triangle.

In summary, if point C lies on the circle with diameter AB, then triangle ABC must be a right triangle with AC and BC as its legs and AB as its hypotenuse. This is a fundamental property of circles and right triangles, and it is important to understand in order to solve various geometry problems involving circles and triangles.

The length of the sides of 3 square are s, s+1 and s+2. find the total perimeter of their total area is 245 square units.

Answers

The side lengths of the three squares are 8, 9, and 10, and the total perimeter is 27 units.

How to find  the total area of the squares?

Let's call the side length and perimeter of the first square "s", the second square "s+1", and the third square "s+2".

The area of a square is given by the formula A =[tex]s^2[/tex], where A is the area and s is the side length.

So the total area of the three squares is:

A_total =[tex]s^2[/tex] + (s+1[tex])^2[/tex] + (s+2[tex])^2[/tex]

We are given that the total area is 245 square units:

A_total = 245

Substituting this into our expression for A_total, we get:

245 =[tex]s^2[/tex] + (s+1[tex])^2[/tex] + (s+2[tex])^2[/tex]

Expanding the squares, we get:

245 = 3[tex]s^2[/tex]+ 6s + 5

Simplifying, we get a quadratic equation:

3[tex]s^2[/tex]+ 6s - 240 = 0

Dividing by 3, we get:

[tex]s^2[/tex] + 2s - 80 = 0

We can factor this quadratic as:

(s+10)(s-8) = 0

So s = -10 or s = 8. Since s must be positive (it represents a side length), we have:

s = 8

Therefore, the side lengths of the three squares are 8, 9, and 10.

The total perimeter is the sum of the side lengths of the three squares:

P_total = s + (s+1) + (s+2)

P_total = 8 + 9 + 10

P_total = 27

Therefore, the total perimeter is 27 units.

Find the absolute maximum value on (0, [infinity]) for f(x)= x^7/e^x.

Answers

The absolute maximum value on the interval (0, infinity) for the function f(x) = x^7/e^x is 7^7/e^7.

To find the absolute maximum value on the interval (0, infinity) for the function f(x) = x^7/e^x, we need to follow these steps:

1. Find the first derivative of the function, f'(x), to determine the critical points where the function might have a maximum or minimum.
2. Evaluate the first derivative at the critical points and determine if it changes sign, indicating a maximum or minimum.
3. Verify if the function has an absolute maximum on the given interval.

Step 1: Find the first derivative f'(x) using the quotient rule.
f'(x) = (e^x * 7x^6 - x^7 * e^x) / (e^x)^2

Step 2: Simplify f'(x) and find the critical points.
f'(x) = x^6(7 - x) / e^x
f'(x) = 0 when x = 0 (not included in the interval) or x = 7

Step 3: Evaluate the first derivative around the critical point x = 7 to determine if it's a maximum or minimum.
f'(x) > 0 when 0 < x < 7, and f'(x) < 0 when x > 7, which indicates that x = 7 is an absolute maximum point.

Now we can find the absolute maximum value by plugging x = 7 into the original function, f(x):
f(7) = 7^7/e^7

Thus, the absolute maximum value on the interval (0, infinity) for the function f(x) = x^7/e^x is 7^7/e^7.

it has a 15% yearly interest rate.
the interest is compounded monthly.
the card has $0 minimum payments for the first four years it is active.

Answers

If it has a 15% yearly interest rate and the interest is compounded monthly and the card has $0 minimum payments for the first four years it is active. Therefore, Emma will owe approximately $529.27 in four years.

To calculate how much Emma will owe in four years, we need to use the compound interest formula: A = P (1 + r/n)^(n*t)

where:

A = the amount of money at the end of the investment period

P = the principal amount (the initial amount of money borrowed)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period in years

In this case, the principal amount is $300, the annual interest rate is 15%, and the interest is compounded monthly (so n = 12). The time period is four years.

Plugging in the values, we get:

A = 300(1 + 0.15/12)^(12*4)

A ≈ $529.27

  3(4x -3y) -(5x -9y) = 3(11) -(-2)

  12x -9y -5x +9y = 33 +2

  7x = 35 . . . . . . . simplify

  x = 5 . . . . . . . . . . divide by 7

  4(5) -3y = 11 . . . . . substitute into the first equation

  9 = 3y . . . . . . . . add 3y-11 to both sides

  y = 3 . . . . . . . . divide by 3

The solution is (x, y) = (5, 3).

Additional comment

We find using a graphing calculator to be the easiest way to solve a pair of simultaneous equations. The attachment shows the solution is the one we found above.

The approach of "substitution" is straightforward, if error-prone. Basically, you solve one equation for either variable, then use that expression in the other equation. Here, for example, you can solve the first for x:

  x = (11 +3y)/4

Then use that in the second equation:

  5(11 +3y)/4 -9y = -2

  5(11 +3y) -36y = -8 . . . . eliminate the denominator

  55 +15y -36y = -8 . . . . . eliminate the parentheses

  -21y = -63 . . . . . . . . . . . simplify, subtract 55

  y = 3 . . . . . . . . . . . . divide by -21

  x = (11 +3(3))/4 = 20/4 = 5 . . . . find x

In the above, we used "elimination." We took advantage of the fact that the y-coefficients were related by a factor of 3. To cancel y-terms, we need to have the equations we "add" have opposite signs for the y-terms. Here, we do that by multiplying the first by 3 (to make -9y), then subtracting the second equation (which has -9y, so will cancel). We could have subtracted 3 times the first from the second, but that would make all the resulting coefficients be negative, which we like to avoid.

Or, we could have multiplied the first equation by -3 to make the y-coefficients opposite, then added the results. (Again, that would give negative coefficients in the sum.) Planning ahead can help avoid mistakes due to minus signs.

The cost function for q units of a certain item is C(q) = 102q-97. The revenue function for the same item is R(q) = 102q+ 52q/Inq a. Find the marginal.cost. b. Find the profit function c. Find the profit from one more unit sold when 8 units are sold.

Answers

a. The marginal cost is constant at $102 per unit.

b. The profit function is 149 + 52q/Inq.

c. The profit from one more unit sold when 8 units are sold is $4.50.

a. To find the marginal cost, we need to take the derivative of the cost function: C'(q) = 102. So the marginal cost is constant at $102 per unit.

b. The profit function is given by:

[tex]P(q) = R(q) - C(q) = (102q + 52q/Inq) - (102q - 97) = 149 + 52q/Inq.[/tex]

c. To find the profit from one more unit sold when 8 units are sold, we need to find the difference between the profit from selling 9 units and the profit from selling 8 units.

Profit from selling 9 units: P(9) = 149 + 52(9)/In9 = 149 + 104 = $253.

Profit from selling 8 units: P(8) = 149 + 52(8)/In8 = 149 + 108.5 = $257.50.

The profit from one more unit sold when 8 units are sold is the difference between these two profits: $253 - $257.50 = -$4.50. This means that selling one more unit when 8 units are sold will result in a loss of $4.50.

There’s are 12 levels in Kianah’s new video game. If he plays the same number of levels each day, what are all the possibilities for the number of days he could doesn’t playing the game without repeating a level

Answers

Kianah can finish the game in 1, 2, 3, 4, 6, or 12 days, depending on how many levels he plays each day.

To find all the possibilities for the number of days Kianah can play the game without repeating a level, we need to find all the factors of 12. The factors of 12 are 1, 2, 3, 4, 6, and 12. These are all the possible numbers of levels Kianah can play each day without repeating a level.

If Kianah plays 1 level each day, he will finish the game in 12 days. If he plays 2 levels each day, he will finish in 6 days. If he plays 3 levels each day, he will finish in 4 days. If he plays 4 levels each day, he will finish in 3 days. If he plays 6 levels each day, he will finish in 2 days. And if he plays all 12 levels each day, he will finish in 1 day.

Therefore, Kianah can finish the game in 1, 2, 3, 4, 6, or 12 days, depending on how many levels he plays each day. It's important to note that these possibilities assume that Kianah is able to complete all the levels he plays each day without getting stuck or repeating any levels.

A circular donut sign has a radius of 3 feet enter the area in square feet of the donut sign round your answer to the nearest 10th

Answers

The area of the donut sign with a radius of 3 feet is approximately 84.8 square feet when rounded to the nearest 10th.

The area of a donut sign can be calculated by subtracting the area of the inner circle from the area of the outer circle. The area of the outer circle can be found using the formula A = πr^2, where r is the radius of the circle.

Thus, the area of the outer circle of the donut sign is A1 = π(3)^2 = 9π square feet. Similarly, the area of the inner circle is A2 = π(0.5)^2 = 0.25π square feet, where the radius of the inner circle is 0.5 feet (which is the radius of the circular hole in the donut sign).

Therefore, the area of the donut sign can be calculated as A1 - A2 = 9π - 0.25π = 8.75π square feet. Using the value of π ≈ 3.14, we get the area of the donut sign as approximately 27.43 square feet. Rounding this value to the nearest 10th gives the final answer of approximately 84.8 square feet.

The solutions of the equation algebraically are x = 5 and x = -7

How to determine the value

From the information given, we have the quadratic equation;

|x| = x2 + x − 35

The sign , '| |' represents the modulus sign and says that the value must be a positive value.

Then, we have;

x² + x + x - 35

add the like terms

x² + 2x - 35

Find the pair factors of -35 that add up to 2, we have;

x² + 7x - 5x - 35

Group the expression in pairs

(x² + 7x) - (5x - 35)

factorize the expression

x(x + 7) - 5(x + 7)

No, the values in the table do not represent a proportional relationship because the y-values are not a constant multiple of the corresponding x-values.

Based on the given table:

x | 0 | 1 | 2 | 3
y | 0 | 3 | 5 | 6

The values in the table do not represent a proportional relationship. To be proportional, all of the y-values should be a constant multiple of the corresponding x-values. However, in this case, the ratio of y/x is not constant (3/1, 5/2, 6/3). Therefore, the relationship is not proportional.

What is triangle?

A triangle is a geometrical shape that consists of three straight sides and three angles. It is a polygon with three vertices, and the sum of its interior angles always adds up to 180 degrees. Triangles are classified based on the length of their sides and the measure of their angles. The most common types of triangles are equilateral, isosceles, and scalene, based on the length of their sides, and acute, right, and obtuse, based on the measure of their angles. Triangles have a wide range of applications in mathematics, physics, engineering, and other fields.

Here,

Therefore, in this triangle, sin(67°) = 67/x, where x is the length of the hypotenuse.

We can rearrange this equation to solve for x:

x = 67 / sin(67°)

Using a calculator, we find that sin(67°) is approximately 0.921, so:

x = 67 / 0.921

x ≈ 72.73
