Find the distance represented by a 3-inch line on a blueprint with a scale of 3/8 inch = 1 foot

irina1246 [14]

Answer:

8 feet

Step-by-step explanation:

Using the scale of 3/8 inch = 1 foot, we can set up a proportion (equivalent ratios) to find the number of feet equal to 3 inches:

$\frac{3}{8}=0.375$

$\frac{inches}{foot}=\frac{0.375}{1}=\frac{3}{x}$

Cross-multiply: 0.375x = 3

Divide by 0.375: 0.375x/0.375 = 3/0.375

x = 8 feet
