Question

if 1 inch equals 10 feet, the arrow on the engineers scale shown in the figure above indicates a length of ___. 00105 - 15_e01eps 5 feet 50 inches 1/2 inch 6 pulgadas

Explanation:

Step1: Identify the measurement on the scale

The arrow points to the 0.5 - inch mark on the engineer's scale.

Step2: Use the given scale ratio

The ratio is 1 inch = 10 feet. So for 0.5 inches, we calculate the length in feet. Let $x$ be the length in feet. We set up a proportion $\frac{1}{10}=\frac{0.5}{x}$. Cross - multiplying gives $x = 0.5\times10$.
$x=5$ feet

Answer:

5 feet
