Question

question 1 of 10 maci has a family photograph with a width of 4 in and a height of 6 in. she wants to enlarge the photograph so that its width is 10 in. what will the height of the enlarged photograph be? a. 15 in b. 14 in c. 13 in d. 12 in

Explanation:

Step1: Set up proportion

Since the ratio of width to height remains the same before and after enlargement, we have the proportion $\frac{4}{6}=\frac{10}{h}$, where $h$ is the height of the enlarged photograph.

Step2: Cross - multiply

Cross - multiplying gives us $4h = 6\times10$.

Step3: Solve for $h$

$4h=60$, then $h=\frac{60}{4}=15$.

Answer:

A. 15 in
