Ok so this person was paid $422.75 this week for working one week. $42.75 though, was added onto her normal paycheck because she worked overtime. So we subtract the $42.75 from the $422.75 to get $380. So if she made that normal money by working for 40 hours we need to find how much money she makes in one hour. SO we just do 380/40 to get $9.50 per hour

Hope that helped.... If i explained it weird and you still don't get it PM me and i can try to reexplain :)

The volume of a CONE-shaped hole is 75pi ft cubed. If the hole is 9 feet deep, what is the radius of the hole?
Arturiano [62]

Answer:

The radius of hole is 5 feet

Step-by-step explanation:

Depth of conical hole = 9 feet

Let the radius of hole be r

Volume of conical hole =\frac{1}{3} \pi r^2 h

So, Volume of conical hole =\frac{1}{3} \pi \times r^2 \times 9

We are given that volume of a CONE-shaped hole is 75pi ft cubed.

So,\frac{1}{3} \pi \times r^2 \times 9=75 \pi

\frac{1}{3} \times r^2 \times 9=75

r^2=\frac{75 \times 3}{9}

r=\sqrt{\frac{75 \times 3}{9}}

r=5

Hence The radius of hole is 5 feet
