Remember, the volume formula of a sphere is

.
Set that equation equal to whatever volume they give you and solve for r.

=

Now solve for r! I know you can do this. If you need help, just comment.
Answer:
27 hours
Step-by-step explanation:
Let her work "x" hours for paperwork
Since, patrolling amount of hours is THREE TIMES that,
Patrolling = 3x hours
Total Hours = 36
That is including paperhour work (x) and patrolling (3x). So we can setup an equation in x and solve for x first:
x + 3x = 36
4x = 36
x = 36/4
x = 9 hours
Amount of Hours for Patarolling = 3x hours = 3(9) = 27 hours
So, she spends 27 hours patrolling
Complete question
<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented
</em>
<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a
</em>
<em>variable, write an equation, and solve the problem.</em>
The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16
Let the cost of green fees per person be y
If Luis and three friends went golfing, this means that 4 people went golfing. The total cost of green fees for all of them will be $4y
If two of the friends rented clubs for $6 each, total amount spent will be $2(6)
The equation that models the statement will then be expressed as;

Solve for y

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.

Answer:
small=15 large=40
Step-by-step explanation:
x=large box
y=small box
55 = x + y
50x + 55y = 2825
50x + 55( 55 - x) = 2825
50x + 3025 - 55x = 2825
0 = 55x - 50 x + 2825 - 3025
0 = 5x - 200
200 = 5x
x=40
y = 15
