Step-by-step explanation:

A ≈12.57in²

d = Diameter

Using the formulas

A=πr2

d=2r

Solving forA

A=1/4πd²=1/4·π·4²≈12.56637in²

Answer:

A = 4π in²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here d = 4, then r = 4 ÷ 2 = 2

A = π × 2² = 4π in²

Answer:

There are many way to solve this problem. But I'm using one X = 5 and X = 8.

Step-by-step explanation:

5 x 10 = 50

50 + 2 = 52

52 + 12 = 64

Heads up

4 + 8 = 12

Answer:

x=8

Step-by-step explanation:

first you have to multiply 2 and x and then 2 and 4. You should get 2x + 8. then you should add comon numwrals which would be 5x and 2x to get 7x. your equation should now be 7x + 8= 64. then subtract 8 from 64 to get 56. it should now be 7x = 56. devide 56 by 7 and 7x by 7. your answer is x=8

Answer:

140

Step-by-step explanation:

first you take the product of 5/6 and 42/1, which is 210/6.

Then you devide that with 5, 210/6/5 = 210/30 or 210/6 . 1/5 = 70.

Next you multiply that with 2; 70 . 2 = 140.

There you go

The length of the table is 22 inches and the width is 13 inches.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

We are given that;

The set of equations

Now,

To solve it, you can use the substitution method. That is, you can substitute x = 2y - 4 into the second equation and get:

70 = 2(2y - 4) + 2y

Simplify and solve for y:

70 = 4y - 8 + 2y

70 = 6y - 8

78 = 6y

y = 13

Now plug y = 13 into the first equation and solve for x:

x = 2(13) - 4

x = 26 - 4

x = 22

Therefore, by the equation the answer will be 13 inches.

Answer:

The absolute value of a number is its distance from 0. We know that distance is always a non-negative quantity. Since the absolute value is a distance, the absolute value is always non-negative.

Answer:

Volume of tennis ball = 11.49 inch³

Step-by-step explanation:

Given:

Radius of tennis ball = 1.4 inches

Value of π = 3.14

Find:

Volume of tennis ball

Computation:

Volume of sphere = [4/3][π][r]³

Volume of tennis ball = [4/3][π][Radius of tennis ball]³

Volume of tennis ball = [4/3][3.14][1.4]³

Volume of tennis ball = [1.333][3.14][1.4]³

Volume of tennis ball = [1.333][3.14][2.744]

Volume of tennis ball = [4.1856][2.744]

Volume of tennis ball = 11.4852

Volume of tennis ball = 11.49 inch³

Answer:

Step-by-step explanation:

PART A

7.5 represents the ounces of water heating up inside the pot.

PART B

40 in the equation will represent the starting point. It can be described as where the temperature started.

PART C

The temperature, of Colton's pot of water after 16 minutes will be 120°  7.5(16) = 120  7.5 being the ounces of water and 16 being minutes.

PART D

After 16 minutes of heating, about 13.3 as additional time will be added for the water to start boiling at 212°.

The temperature in degrees Fahrenheit of colton's pot of water after 16 minutes is 160° F. The additional time to the nearest minute will be needed for the water to boil is 7 minutes approximately.

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

For this case, it is specified that:

So, if the water is boiling for x = 16 minutes, then the temperature would be:

[tex]y = 7.5 \times 16 +40 = 160^\circ \: \rm F[/tex]

Also, we need to make the temperature reach to 212 degree Fahrenheit after 16 minute of boiling.

Let it takes T time (in minutes more) to reach 212 degree Fahrenheit, then: y = 212, x = 16 + T

Putting these values in the equation, we get:

[tex]y = 7.5x + 40\\212=7.5\times(16+T) + 40\\212 = 120 + 7.5T + 40\\7.5T = 212-160\\\\T = \dfrac{212-160}{7.5} = \dfrac{52}{7.5} \approx 6.93 \: \rm minutes \approx 7 \: \rm minutes[/tex]

Thus, the temperature in degrees Fahrenheit of colton's pot of water after 16 minutes is 160° F. The additional time to the nearest minute will be needed for the water to boil is 7 minutes approximately.

Answer:

Fatima ate more pizza

Step-by-step explanation:

Assume

The total pizza = 1

Tareq eats 2/8 of his pizza

Tareeq = 2/8 of 1

= 2/8 * 1

= 2/8

= 0.25 of his pizza

Fatma eats 3/4 of her pizza

Fatima = 3/4 of 1

= 3/4 * 1

= 3/4

= 0.75 of her pizza

The pizza is identical in size

Therefore,

Fatima ate more pizza

I got to know this by finding the decimal of fraction eaten and picking the larger decimal value as who ate more pizza

The beginning part of the question is missing and it says;

The measures of center can be used to summarize the number of pets that students own. Cameron asked eight of his classmates how many pets they own. The results are listed below.

1, 0, 2, 0, 3, 7, 0, 2, 4

Answer:

Median

Step-by-step explanation:

Let's rearrange the results from least to most.

0, 0, 0, 1, 2, 2, 3, 4, 7

Mode is the most occurring number which in this case is zero, so Cameron can't use that to convince his parents to get another pet.

Median is middle number and in this case is 2.

Mean is; sum of results/ number of results = 19/9 = 2.11

Thus, the best measure of tendency for Cameron to use is median.

Okay so let's break this down into TWO shapes :
