The volume of a sphere is given by

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3 r^3

Multiply each side by 3/4

3/4 *121.5 = 3/4 * 4/3 r^3

91.125 = r^3

Take the cube root of each side

(91.125)^ (1/3) = r^3 ^(1/3)

4.5 = r

Answer:

The numbers are 8 and 6

Step-by-step explanation:

Let x and y be the two numbers

x+y = 14

x-y = 2

Add the two equations together

x+y = 14

x-y = 2

--------------

2x +0y = 16

Divide by 2

2x/2 = 16/2

x = 8

Now find y

x+y = 14

8+y =14

Subtract 8 from each side

8+y-8 =14-8

y =6

The numbers are 8 and 6

Answer:

8 and 6

What is the volume of the following rectangular prism?

Answers

The volume of a rectangular prism is a measurement of the occupied units of a rectangular prism. ... It is also defined as the number of units used to fill a rectangular prism. The volume of the rectangular prism is equal to the area of the base times its height.

V of rectangular prism formula: L x W (some combine these two and say “area of the base”) x H.
They gave you the “area of the base” as 25/4 is in units squared. So you just need to multiply 25/4 x 8/5 = 200/20 which is 10 units cubed.
If decimals are easier 25/4 = 6.25 and 8/5 = 1.6. So 6.25 x 1.6 = 10 units cubed.

$18.75 to $18.60 identify the percent of change as an increase or decrease . then find the percent of change round to the nearest tenth of a percent , if necessary

Answers

Answer:

0.8%

Step-by-step explanation:

There is a decrease in percentage by 0.8%.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The given decimal numbers are $18.75 and $18.60.

We know that, percentage change = (Original price-New price)/Original price ×100

= (18.75-18.60)/18.75 ×100

= 0.15/18.75 ×100

= 0.008×100

= 0.8%

Therefore, there is a decrease in percentage by 0.8%.
