Answer:
7690.6 cubic feet
Step-by-step explanation:
V=πr^2h
= π x 12^2 x 17
= 7690.6 cubic feet
For this question you have to solve the equation backwards.
A = 1/2 x (b1 + b2) x h
In order to get rid of the 1/2 (since it's division) multiply each side by 2
now we have: 2A = (b1 + b2) x h
Now do the same to the get rid of the (b1 + b2) (divide each side by it)
2A/(b1 + b2) = h

The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
<h3>What is Impulse?</h3>
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
- Mass of baseball m = 0.25kg
- Time of contact t = 0.0075s
- Force exerted F = 18500N = 18500kgm/s²
We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.

Answer:
Step-by-step explanation:
<u>20% of juice has:</u>
- 10*0.2 = 2 cups of extract
<u>If x cups of juice added we'll have:</u>
- 2 + x*0.15 = 0.17(10 + x)
- 2 + 0.15x = 1.7 + 0.17x
- 0.17x - 0.15x = 2 - 1.7
- 0.02x = 0.3
- x = 0.3/0.02
- x = 15
