Step-by-step explanation:
<u>Step 1: Define</u>
3n - 5 = 22
<u>Step 2: Solve for </u><em><u>n</u></em>
- Add 5 to both sides: 3n = 27
- Divide 3 on both sides: n = 9
n=# of nickels
q=# of quarters
$12 is 1200 cents
5n+25q=1200
n=q
substitute q for n or n for q
5q+25q=1200
30q=1200
q=1200/30
q=40 quarters and therefore n=40 nickels
40 quarters is $10 and 40 nickels is $2, therefore you have $12
Hope this helps.

The volume of a sphere is computed as
So, the volume of a quarter-sphere is
