Step-by-step explanation:
It would be 10 times greater im pretty sure.
Answer:
He washed 10 cars.
Step-by-step explanation:
To make this easier covert 1/2hours into 1/4 hours. 2 1/2 = 4/2+1/2 = 5/2. Now take 5/2 and make it 1/4th's, 5/2 = 10/4. It takes 1/4 hours to wash one car so, 10/4 divided by 1/4. Don't divide fractions so, 10/4 x 4/1, we switch the second number around to get 40/4. Now we can simplify, 40/4 = 10.
Answer:
I strongly believe that 8 percent of 500 is forty so I would say C. sorry if Im wrong.
Step-by-step explanation:
hope this helped
1)
The formula for calculating the cone volume is:

Data:
V (volume) = ?
h (height) → h = 12 in
d (diagonal) = 9 in , if: d = 2*r , soon: 9 = 2*r → 2r = 9 → r = 9/2 → r = 4.5 in
Use:

Solving:





2)
The circle area formula is:

Data:
A (area) = ?
d (diagonal) = 19 Km , if: d = 2*r , soon: 19 = 2*r → 2r = 19 → r = 19/2 → r = 9.5 Km
Use:

Solving:




3) False, because it's the volume, the number of cubic units needed to fill a space.
