Question:

Find the volume of a cylinder with a diameter of 14 in and a height of 10 in. Leave your answer in terms of pi​

Answers

Answer 1
r = 7 d = 14 (to find the radius d ÷ 2) h = 10

(2πr²)

2 x 3.14 x (7x7)
2 x 3.14 x 49 = 307.72

(πdh)

3.14 x 14 x 10 = 439.6

Take the two answers and add.

307.72 + 439.6

Final answer = 747.32

I can’t help you with the first one because I can’t see the choice. I can help you with the second.
For the second one, you can have two ways of doing this:

-225 - (225 x 20% or 0.20)
-225 x (100% - 20%)

However you do it, your answer should be..
*calculating intensifies*
180. So your answer should be $180 for part B.

For part C, they want to know the cost of the coat PLUS the boots during the sale.

So you can do either this:

(225 + 130) x 80% *cuz 100% - 20% is 80%. Don’t ask where the 100% came from cuz I learned this months ago and my brain hates me so-*

Or this: (225 x 80%) + (130 x 80%)

Either way, your answer would have come out to..
*more calculating intensifies*

284. Yeah. Your answer would be $284.

And if you get it wrong, iz my fault :) not urs

C ≈ 3.14 • 26
C ≈ 81.64
The circumference is 81.6 in to the nearest tenth of a inch

3)

C = 3.14 (13)
C = 40.82
C = 40.8

C = 3.14 (2 • 5)
C = 3.14 (10)
C = 31.4

the weights of ten cats in pounds are 14, 10, 11, 9, 12, 8, 8, 10, 7, and 10. what is the mean absolute deviation of the weights of the cats?

Answers

Answer:

HOW TO DO STEP BY STEP:)

Original set ={14, 10, 11, 9, 12, 8, 8, 10, 7,10}

n = 8 is the number of values in that set above

Add up the values 12+11+7+10+10+11+6+8+14+8 = 97

Divide that sum by n = 8 to get 97/8 = 12. So the mean = 12

For each value in the original set {14, 10, 11, 9, 12, 8, 8, 10, 7,10} subtract off the mean = 12. Apply the absolute value to ensure the result is positive or zero

|x - mean| = |14 - 12| = -2

|x - mean| = |10 - 12| = 2

|x - mean| = |11- 12| = 1

|x - mean| = |9 - 12| = 3

|x - mean| = |12 - 12| =0

|x - mean| = |8 - 12| = 4

|x - mean| = |8 - 12| = 4

|x - mean| = |10 - 12| =2

|x - mean| = |7 - 12| = 5

|x - mean| = |10 - 12| = 2

The set of results we get are: {-2,2,1,3,4,4,2,5,2 } -2,2,1,3,4,4,2,5,= 21, then we divide 21 that over n = 12 (21/12) to get  = 1.75

Therefore the mean absolute deviation (MAD) is 1.75

Answer:

So lol im sorry i kinds just calculated it up on the calculator wont be able to provide an explanation but it gave me 1.72 as the Mean Absolute Deviation so the answer would be 1.72 pounds

A hamburger costs 30¢ more than a hot dog and 20¢ less than a cheeseburger. If 3
hamburgers cost 75¢ less than 2 hot dogs and 2 cheeseburgers, how much does a
hamburger cost?

Answers

Let h be the price of a hamburger, d be the price of a hot dog and c be the price of a cheeseburger
3+d=h —(1)
c-20=h —(2)
3h=2d+2c-75 —(3)

Sub (1), (2) into (3)
3h=2(h-3) + 2(h+20) -75
3h =2h-6+2h+40-75
3h=4h-41
h=41

Therefore, the price of a hamburger is $41
The price of the hamburger is 41

How many cubic centimeters of air would be needed to completely fill a tennis ball with a diameter of 3 inches? Use 3.14 for \piπ. Round your answer to the nearest whole number.

Answers

Answer:

232

Step-by-step explanation:

1 inch = 2.54 cm

3 inches = 3*2.54

3 inches = 7.62 cm

r = d/2

r =7.62 / 2

r = 3.81 cm

V = 4/3 pi r^3

V = 4/3 * 3.14 * 3.81^3

V = 4/3 * 3.14 * 55.31

V = 232

2) You hired an interior designer from Atlanta Interior Design Inc. to help decorate the new game
room; however, the interior designer earns a commission on their work. If Atlanta Interior Design
gets to keep 30% of the money from the sale, what would the company's bill have to be to make at
least $500?

Answers

Maybe 833. I don’t know if I’m correct or not plz tell me

Answer:

Approximately, $1,666.66

Step-by-step explanation:

Since Atlanta Interior Design is keeping 30% of the money from the overall sale, and their 30% is supposed to be $500, therefore you would have the following layout:

$500     30%

-------- = --------

   x        100%

Therefore, you would do (500 x 100)

                                         ----------------- = 1,666.66~

                                                30

To check this, you could do:

       x              30%

--------------- = --------

1,666.66~      100%

Therefore,

(1,666.66~ * 30)

----------------------- = 499.99~

         100
