FromTheMoon [43]
If you would like to know what is the area of the wall, you can calculate this using the following steps:

area = length * width
area = 9 1/3 feet * 8 1/8 feet = 28/3 feet * 65/8 feet = 455/6 = 75 5/6 square feet

The area of the wall is 75 5/6 square feet. 

If the mural is 100 square feet, it won't fit on the wall, because 100 > 75 5/6.

Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run
kipiarov [429]

Answer:

6 laps

Step-by-step explanation:

Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run

One tenth of a mile = 1/0

Three fifths of a mile = 3/5

From the question:

1/10 mile = 1 lap

3/5 mile = x

Cross Multiply

1/10 mile × x = 3/5 mile × 1 lap

x = 3/5 mile × 1 lap/ 1/10 mile

x = 3/5 ÷ 1/10

x = 3/5 × 10/1

x = 6 laps

Therefore, for there fifths of a mile(3/5) he needs to run 6 laps
