On a scale drawing with a scale of 1/20, the height of the building is 8 inches. How tall is the actual building in feet?

1 answer:

3 0

That means its downgraded to 1/20 of actual height, let actual height is x. Then
(1/20) * x = 8, x = 20 * 8 = 160, actual height = 160 inch
160 inch = 160/12 feet = 13 1/3 feet or 13.333 feet.

Answer:

14400

Step-by-step explanation:

X - X × 75%=3600

X - X × $\frac{75}{100}$ = 3600

X - $\frac{3X}{4}$ = 3600

$\frac{4X-3X}{4}$ = 3600

$\frac{X}{4}$ = 3600

X = 3600 × 4

X = 14400
