A standard showerhead in Andrew's house dispenses 8 gallons of water per minute. Andrew changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead.y = 3x

How much water does Andrew save each day with the change in showerheads if he uses the shower for 8 minutes each day?

5 gallons
16 gallons
24 gallons

Step-by-step explanation:

OLD SHOWERHEAD

y=8x

y=8(8)

y=64

NEW SHOWERHEAD

y=3x

y=3(8)

y=24

64-24=40

Find the midpoint of the line segment whose endpoints are (-2, 5) and (4, -9).

Answers

Solving for the midpoint can be done by looking for the average of each of the given x-coordinates and y-coordinates. The 2 obtained averages are the new x-coordinate and y-coordinate. This shown below:

Midpoint = ( (-2 + 4)/2 , (5 + -9)/2 )
Midpoint = (1,-2)

Therefore, the new midpoint is (1,-2)

The area of a bathroom floor measures 2 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square feet. How many tiles are needed to cover the floor?

Answers

The dimensions of the bathroom floor is given as 2 yards by 3 yards.
Then
The area of the bathroom floor in question = (2 * 3) square yards
                                                                     = 6 square yards
We already know that
1 square yard = 9 square feet
So
The area of the bathroom floor in question = (6 * 9) square feet
                                                                     = 54 square feet
Area covered by each custom tiles = 11/2 square feet
Then
Number of tiles required to cover the bathroom floor = 54/(11/2)
                                                                                     = (54 * 2)/11
                                                                                     = 108/11
                                                                                     = 9.81
So the number of tiles required to cover the bathroom flooring is 10. Since fraction of tiles cannot be bought, so 10 tiles are required.
