- <em>It takes</em><u> 2.5 minutes </u><em>to fill the tank.</em>
Explanation:
The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:
- Net rate = rate of filling - rate of leaking
- Net rate = 5 liters/minute - 1 liter/minute
- Net rate = 4 liters/minute
Thus, consiedering the tank is empty at the beginning, the time is:
- Time = Volume of the tank / net rate of filling
- Time = 10 liters / (4liters/minute)
- Time = 2.5 minutes ← answer
There are 4320 minutes in 3 days
Start by writing a formula, where 
is Brad's purchase price and 
is the original price.
Subtract 
from both sides.
Multiply both sides by 
.
E pi and F pi and (for third one) are correct answers
width = 83 cm
Perimeter = 2(width) + 2(length)
So if l = 99 cm, and p = 364, then
364 = 2w + 2(99)
364 = 2w + 198
166 = 2w
w = 83 cm
