- <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

We need the perimeter of the window for framing
The window is in the shape of a rectangle with the height of
feet and width of
. The diagram of the shape is shown below
The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.
The perimeter of the window is
=
We have two whole numbers 18 and 12 and two fractions
and
Adding the two fractions that have different denominator
, which is an improper fraction which we can change into a mixed number
So the perimeter of the window is
and the length of wood needed for the frame is
feet
