Answer:
150 + 4x = 330
4x = 180
x = 45
Step-by-step explanation:
The formula is 1/2mv²
1/2*0.145*40²=0.0725*1600=116
Therefore the kinetic energy of that object is 116 joules.

Step-by-step explanation:
(. 8)^8=0.16777216
Answer:
c
Step-by-step explanation:
To answer this question you will need to find the total volume the rain barrel can hold. Then find the volume of water that it is currently holding.
Subtract these two amounts to find the total amount of water or can still hold.
Then convert this amount to gallons.
1. V = pi x r^2 x h
3.14 x 1.25^2 x 3.5
V = 17.17 cubic feet
2. Same formula
3.14 x 1.25^2 x 1.5
V = 7.36 cubic feet
3. 17.17 - 7.36 = 9.81 cubic feet
4. 9.81 x 7.5 = 73.575 gallons or approximately 74 gallons.
