Yanka [14]

Answer: 144 minutes

Step-by-step explanation:

Based on the information that has been given in the question, the minutes that the slower pipe alone can use in filling the tank can be denoted by y minutes.

Therefore, the faster pipe will fill it in 1/3 × x = x/3 minutes.

Therefore,

1/x + 3/x = 1/36

4/x = 1/36

x = 36 × 4

x = 144

The number of minutes taken by the slower pipe will be 144 minutes.

The length of a rectangle is 3 ft less than twice the width, and the area of the rectangle is 44 ft^2 . Find the dimensions of t
Vinvika [58]

Answer:

Hi there! The width of the rectangle is 5.5ft and the length is 8ft.

Let the width of the rectangle be represented by X. This learns us the length of the rectangle is 2X - 3.

Therefore the area of the rectangle (which is length * width) would be

Since the area of the rectangle is 44 ft^2, we end up with the following equation.

Since X represents the width (and width can't be negative), the width of the rectangle is 5.5ft

The length is

2X - 3 = 2 × 5.5 - 3 = 11 - 3 = 8ft.
