Answer:
To drain the water tower it will take 36 hours.
Step-by-step explanation:
Given:
A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.
Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.
Gallons of total water in the tower ÷ Gallons of water drained per hour


Therefore, to drain the water tower it will take 36 hours.

Answer:
120poles
Step-by-step explanation:
Given
Length of each poles of the paddock = 30
Since a square has 4 sides, the perimeter of the square shaped paddock is what we are to look for.
Perimeter of a square = 4L
L is the length of each side of the paddock
Perimeter = 4(30)
Perimeter of the square = 120
Hence he used 120poles for the paddock
