Step-by-step explanation:
use the distance formula. calculate the distance between AB and then between CD showing AB = CD.
then use the distance formula on BC and AD, showing they are equal.
d=√((x_2-x_1)²+(y_2-y_1)²)
Answer:
The amount Trevor's family pay per minute on shower water is $0.005.
Step-by-step explanation:
The cost of water is,
Cost = $0.20/liter
Amount of water used over the entire month:
Amount of water used = 72 liters
Compute the total water cost as follows:
Total water cost = Amount of water used × Cost
= 72 × 0.20
= $14.4/liter
The average number of minutes each person showered is:
Average number of minutes = 480 minutes.
The number of people in Trevor's house:
N = 6
Compute the total amount of time the 6 person showered as follows:
Total amount of time = Average number of minutes × N
= 480 × 6
= 2880 minutes
Compute the pay per minute on shower water as follows:
Pay per minute on water = Total water cost ÷ Total amount of time
= $14.4 ÷ 2880
= $0.005
Thus, the amount Trevor's family pay per minute on shower water is $0.005.
Remember, a/(c/d)=(a)(d/c)

Answer:
The area of the backyard is <u>944 ft²</u>.
Step-by-step explanation:
Given:
a = 23 ft, b = 32 ft, and c = 36 ft.
Now, to find the area of the backyard.
So, we get a rectangle and a triangle if we divide the figure.
Thus, a rectangle and a triangle as shown in below figure.
So, a = 23 ft, b = 32 ft, c = 36 ft, and d = 32 ft.
And, e = 36 - 23 = 13 ft.
Now, to get the area of the rectangle we put formula:
Area =
Now, to get the area of the triangle we put formula:
So, to get the total area of backyard we add both the areas of the rectangle and triangle:
Therefore, the area of the backyard is 944 ft².
