The correct Answer is:
To solve the equation \( \sqrt{\frac{x}{7}} = 2.74 \), we will follow these steps: ### Step 1: Square both sides To eliminate the square root, we square both sides of the equation: \[ \left(\sqrt{\frac{x}{7}}\right)^2 = (2.74)^2 \] ### Step 2: Simplify the left side The left side simplifies to: \[ \frac{x}{7} = (2.74)^2 \] ### Step 3: Calculate \( (2.74)^2 \) Now we calculate \( (2.74)^2 \): \[ (2.74)^2 = 7.5076 \] ### Step 4: Set up the equation Now we have: \[ \frac{x}{7} = 7.5076 \] ### Step 5: Multiply both sides by 7 To solve for \( x \), we multiply both sides by 7: \[ x = 7 \times 7.5076 \] ### Step 6: Calculate \( x \) Now we perform the multiplication: \[ x = 52.5532 \] ### Step 7: Round if necessary Since the options provided are rounded, we can round \( 52.5532 \) to \( 52.55 \). Thus, the value of \( x \) is: \[ \boxed{52.55} \]
