The width of a rectangle is 1 3/4 feet. The rectangle is 2 1/2 feet longer than it is wide. What is the length of the rectangle?

sp2606 [1]

Answer:

length=4 1/4

Step-by-step explanation:

1 3/4 + 2 1/2
convert 2 1/2 into 2/4 since 2 is half of 4
add the converted number and 1 3/4 fractions
2/4 and 3/4 added will make 1 1/4
add 1 1/4, 2 and 1 and it will equal 4 1/4

A circle is made up of 360 degrees. Lets find the decimal form of each part of the circle.

White: 122.4/360 = 0.34

Red: 115.2/360 = 0.32

Silver: 68.4/360 = 0.19

Blue: 54/360 = 0.15

Now, solve for the car color that is not red or blue.

1 - (0.15 + 0.32)

1 - (0.47)

0.53

Therefore, the answer is C.

Best of Luck!
