The answer is 196/3 pi in^3. All you have to do is multiply 7x7, then you have to multiply that by 1/3 and 4, and you get 65.333333333. Then, you have to turn it into a fraction. You have to multiply 65 by 3, then add one, and you get 196/3 pi in^3.
Answer:the number of gallons of water left is 3.5
Step-by-step explanation:
The initial amount of water in the container is 4 3/8 gallons. Converting 4 3/8 gallons to improper fraction, it becomes 35/8 gallons of water.
A hole in the container causes 7/8 gallon to leak out. The number of gallons of water left in the container would be
Initial amount - amount that leaked. It becomes
35/8 - 7/8 = 28/8 = 3 4/8 = 3.5 gallons of water
-(26) - 3y = 4
-3y = 30
y = -10
First subtract the weight the dog weighs now to the weight he was:
48.9
- 29.7
------------
19.2
Then take the number you got which is the weight the dog gain in total, and divide it by the months the dog gained weight to get the average weight gained each month:
19.2/8 = 2.4
The average weight gain each month was 2.4 pounds.
Hope this helped you!
Your multiplying by -4 each time
-1x-4=4
4x-4=-16
-16x-4=64
