Question

if 7 three - megawatt wind turbines can supply enough electricity to power 4500 homes, how many turbines would be required to power 24750 homes? if necessary, round your answer to at least one decimal place. turbines

Explanation:

Step1: Set up the proportion

Let \(x\) be the number of turbines needed. The proportion is \(\frac{7}{4500}=\frac{x}{24750}\).

Step2: Cross - multiply

Cross - multiplying gives \(4500x = 7\times24750\).

Step3: Solve for \(x\)

First, calculate \(7\times24750 = 173250\). Then \(x=\frac{173250}{4500}\).
\(x = 38.5\)

Answer:

\(38.5\)
