If wendell creates a scale drawing using the scale 1 inch to 10 feet, what will the dimensions of the deck in the scale drawing be?

The dimensions on the scale drawing would be 1 inch by 0.8 inches.

The scale is 1 in: 10 ft; since the actual width of the deck is 10 ft, then it will be 1 inch on the scale.  To find the width:

1/10 = x/8

Cross multiply:
1*8 = 10*x
8 = 10x

Divide both sides by 10:
8/10 = 10x/10
0.8 = x

The width on the scale drawing will be 0.8 inches.
