Alexis scale drawing represents the longest side of the storage bin as 2 3/4 inches. What is the actual length, in feet, of the
Whitepunk [10]

Answer: The correct answer is C,

5 1/2 feet

Step-by-step explanation:

Alexis' scale drawing represents the longest side of the storage bin as 2 3/4 inches. Converting to improper fraction, it becomes 11/4 inches. This is also 2.75 inches.

The scale used is 1/2 inch = 1 feet. This means that a length of 1 feet of the longest side of the actual storage bin is 1/2 inch on the drawing.

Let the actual length, in feet of the longest side of the storage bin be x feet. Therefore

If 0.5 inch = 1 feet

2.75 inch = x

0.5x = 2.75 × 1

x = 2.75/0.5 = 5.5 feet

The normal cost of a basketball is $21.50. We purchased the basketball for Mason using a coupon for 25% off. How much did we pay
PilotLPTM [1.2K]
First find 25% of 21.5. You can do this by multiplying .25 by 21.5. That gives you 5.375. Subtract that from 21.5. That gives you 16.125. Money only has two decimal places so round 16.125 up to 16.13 and that's your answer! <3
