What is the approximate volume of a cone with a height of 6 mm and radius of 18 mm? Use 3.14 to approximate pi, and express your final answer to the nearest tenth.

Answers

Given:
radius = 18mm
height = 6mm
pi = 3.14

volume of a cone is computed by multiplying pi, radius raised to the 2nd power, and height, which has been divided by 3.

v = πr²h/3

v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm²  x 2mm
v = 2034.72 mm³

volume rounded to the nearest tenth would be 2034.70 mm³

Answer

V = 2034.72 mm³

if Kassidy earns 8$ per hour and Andrea earns 10$ per hour how much more in PERCENT% does Andrea make than Kassidy?

Answers

Subtract the numbers.

10 - 8 = 2

Divide it to the smaller number:

2 / 8 = 0.25

Multiply by 100:

0.25 * 100 = 25%

Three equivalent ratios to 5/2

Answers

To find equivalent ratios, we just need to perform the same action to each the top and bottom number.

5/2 = 5*2/2*2=10/4

5/2=5*4/2*4=20/8

5/2=5*10/2*10=50/20

Three equivalent ratios to 5/2 are 
10/4 , 20/8 , and 50/20
The answer to this is 10/4,15/6 and 20/4

Vince bought 6 boxes of worms to use as bait while fishing with his friends. If each person uses exactly 3/8 of a box of worms, how many people can share the worms.

Answers

We are given the following information:

each person uses 3/8 a box

there are 6 boxes

Because each box is (8)/(8), and there are 6 boxes, we know that 1 person is (3)/(8*6), or (3)/(48).

In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):

48 / 3 = 16

Therefore, 16 people can share the worms.

Hope this helps! :)

Corey needs 24 boards that are 47 1/2 inches long.A. how many feet of boards should he buy? explain.
B. If you can only buy 8-foot boards, how many should he buy?explain

Answers

Answer with explanation:

Number of boards need by corey =24

Length of each board is 47 (1)/(2)\n\n=(95)/(2)

Length in inches of board that corey should buy

          (95)/(2)* 24\n\n=95*12\n\n=1140inches

1 foot=12 inches

(1)/(12) \text{foot}=1\text{inches}\n\n(1140)/(12) \text{foot}=1140\text{inches}\n\n95\text{foot}=1140\text{inches}

So, Length in feet of board =95 foot

B.

Length of each board = 8 foot

Total Length in feet of board =95 foot

So, number of boards that corey should buy

              (95)/(8)\n\n=11(7)/(8)

=Approximately 12 Boards
A. 95 feet
B. 12, because that would get you 96 feet of board, and if you only got 11, then you would only have 88 feet of boards which is not enough.

Please, can you help.... I'm really confused. I need an answer really fast. Thank you

Answer:

Mean for Labradors: 65

Step-by-step explanation:

This is how to find the M.A.D.

Step 1. Find the mean. To do that, you add all the numbers and divide that number by how many numbers you have which is 10. All the numbers together is 650. That divided by 10, is 65. That is your mean.

Step 2. Once you have that, subtract the mean from all 10 numbers.

Step 3. Find the mean of the 10 numbers which you have subtracted 65 (the mean) from. If the number you subtracted is a negative, make it a positive.
