Answer:

56.54 inches

Step-by-step explanation:

If the radius is 3 inches, to find the area of the circle your equation would be A = (pi) x r^2

Your equation would look like this:

A = (pi) x 3^2

A = 28.27

Now to get the volume of the pie, you would multiply 28.27 x 2 which gives you an answer of 56.54 inches.

Answer:

110.5 inches

Step-by-step explanation:

A=( a + b) / 2 h

A = (8 + 9) / 2 x 13

A = 17 / 2 x 13

A = 110.5 inches

The 16-inch pizza is a better deal as it costs about $0.10 per square inch while the 10-inch pizza costs about $0.13 per square inch.

Donnie's Pizza Palace Diameter (in.) Cost ($) Cost per Square Inch ($/in²)

10-inch 10 10 0.13

16-inch 16 20 0.1

To determine which pizza is the better deal, we need to compare the cost per square inch of each pizza.

For the 10-inch pizza:

Cost per square inch = Cost / (π x [tex](diameter/2)^2)[/tex]

Cost per square inch = 10 / [tex](3.14 x (10/2)^2)[/tex] ≈ $0.13

For the 16-inch pizza: Cost / (πx x [tex](diameter/2)^2)[/tex]

Cost per square inch =[tex]20 / (3.14 x (16/2)^2) ≈ $0.10[/tex]

Therefore, the 16-inch pizza is a better deal as it costs about $0.10 per square inch while the 10-inch pizza costs about $0.13 per square inch.

The surface area of the triangular prism is 891 square inches, calculated by finding the area of each face (two triangular and three rectangular) and adding them up.

To find the surface area of the triangular prism, we need to find the area of each face and add them up.

The triangular prism has two identical triangular faces and three rectangular faces. The triangular faces have base 9 inches, height 12 inches, and hypotenuse 15 inches. The area of each triangular face can be found using the formula for the area of a triangle:

Formula for area of each triangular face = (1/2) x base x height

= (1/2) x 9 x 12

= 54 square inches

The prism also has three rectangular faces, each with length equal to the base of the triangle (9 inches) and width equal to the height of the prism (29 inches). The area of each rectangular face can be found using the formula for the area of a rectangle:

Area of each rectangular face = length x width

= 9 x 29

= 261 square inches

Hence, the triangular prism's total surface area is:

Total surface area = 2(Area of each triangular face) + 3(Area of each rectangular face)

= 2(54) + 3(261)

= 108 + 783

= 891 square inches

Therefore, the surface area of the triangular prism is 891 square inches.

It will take 2.2 hours for the two trains to meet.

We can find the time taken by the two trains to meet by using the formula,

large Time=Distance/Speed

Let's consider the time taken by the two trains to meet be "t".The distance between two trains = 418 miles.

Now, the first train is traveling at a speed of 85 mph and the second train is traveling at a speed of 105 mph.

Let's calculate the distance covered by both the trains in time "t".The distance covered by the first train in time "t"=85t.

The distance covered by the second train in time "t"=105t.

So, the total distance covered by both the trains in time "t" is,

Distance covered = 85t+105t=190t.

But we know the distance between the two trains is 418 miles.

Therefore,190t = 418

Now, solve for "t"t = 418/190t = 2.2 hours

Therefore, the two trains will meet in 2.2 hours.

Step-by-step explanation:

Therefore, the man finished his trip at 8:40 pm with total travelling time of 10 2/3 hours.

In mathematics, a fraction is a representation of a part of a whole or a ratio between two quantities. It consists of two numbers, a numerator and a denominator, separated by a horizontal line, also called a fraction bar or a vinculum. The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts that make up the whole.

Here,

We can solve this problem using the formula:

distance = rate x time

Let's start by finding the time it took for the man to travel 450 kilometers at an average speed of 50 kilometers per hour:

time = distance / rate

time = 450 km / 50 km/h

time = 9 hours

So the man spent 9 hours travelling. However, he also took two breaks: a 40-minute rest and a 1-hour lunch break. We need to convert these times to hours to include them in our calculation.

40 minutes is equal to 40/60 = 2/3 hours, and 1 hour is simply 1 hour. So the total time the man spent travelling, including the breaks, is:

total time = 9 hours + 2/3 hours + 1 hour

total time = 10 2/3 hours

To find the finishing time, we add the total time to the starting time of 10 am:

finishing time = 10 am + 10 2/3 hours

finishing time = 8:40 pm (rounded to the nearest minute)

Triangle XYZ will be translated to X'Y'Z' and the coordinates of Z' are (6,7).

A transformation known as a translation involves shifting each point in an image uniformly in one direction. It is also a type of transformation where every point in a figure is moved by the same amount in the same direction, producing a new figure that is identical to the original.

From the graph,

The coordinates of X are (7, 11)

The coordinates of Y are (10, 14)

The coordinates of Z are (8, 7)

When triangle XYZ is translated to X'Y'Z', the X-coordinate is given as (5, 11), which means the X-coordinate shifts left 2 points, so we need to subtract 2 from X-coordinate and keep Y-coordinate as it is.

Therefore the coordinate of the triangle X'Y'Z' are as follows,

The coordinates of X' are (7-2, 11) = (5,11)

The coordinates of Y' are (10-2, 14) = (8, 14)

The coordinates of Z' are (8-2, 7) = (6, 7)

The probability of landing in the color green is P = 0.41, and out of 160 spuns, we can expect to get the color green 66 times.

We have a table and we want to use it to find the probability of the spinner landing on green.

It is equal to the quotient between the number of times that we got green and the total number of times that we spun the spinner.

We got green 325 times, and the total number is:

T = 116 + 325 + 359

T = 800

Then the probability is P = 325/800 = 0.41

b) If it is spun 160 times, then we will get 0.41 times 160 green landings, it is:

160*0.41 = 65.6

This can be rounded up to 66, we can expect to land in the green section 66 times.

In Geometry, a reflection across or over the x-axis is modeled and represented by the following transformation rule (x, y) → (x, -y). Therefore, a reflection across or over the x-axis would maintain the same x-value while the sign of the y-value would change from negative to positive or positive to negative as the case may be.

One of the vertices of triangle A is given by:

When a translation is applied to triangle A', one of the corresponding or resulting vertices of triangle B is given by:

The total probability is 2.5% + 2.5% = 5.0%, which is equivalent to 0.05 or 95.00% in decimal form.

If a random variable follows a normal distribution, the probability that the random variable is 1.96 standard deviations below the mean is 95.00%.Step-by-step explanation:

Z-value for 1.96 standard deviations below the mean can be calculated as follows:

Z=(x-μ)/σ=(-1.96)

Where x is the value of the random variable, μ is the mean, and σ is the standard deviation.To find the probability, we can use a standard normal distribution table.

The table gives the probability of a standard normal random variable Z being less than or equal to a given value, denoted by P(Z ≤ z).

The Z-value we calculated is -1.96, so we look up the corresponding probability in the table:

P(Z ≤ -1.96) = 0.025.

The probability that the random variable is 1.96 standard deviations below the mean is therefore:

P(Z ≤ -1.96) = 0.025 = 2.5%

However, since we are interested in the probability that the random variable is exactly 1.96 standard deviations below the mean, we need to use a two-tailed test.

The probability of being below the mean by 1.96 standard deviations is 2.5%, and the probability of being above the mean by 1.96 standard deviations is also 2.5%.
