Question

dagny measures and finds that she can do a vertical jump that is 27.5% of her height. if dagny is 48 inches tall, how high can she jump? enter your answer in the box. inches

Explanation:

Step1: Identify the formula for percentage calculation

To find a percentage of a number, we use the formula: \( \text{Percentage of number} = \text{Number} \times \frac{\text{Percentage}}{100} \)

Here, the number is Dagne's height (\( 48 \) inches) and the percentage is \( 27.5\% \).

Step2: Substitute the values into the formula

Substitute \( \text{Number} = 48 \) and \( \text{Percentage} = 27.5 \) into the formula:

\( \text{Jump height} = 48 \times \frac{27.5}{100} \)

First, calculate \( \frac{27.5}{100}=0.275 \)

Then, multiply \( 48 \) by \( 0.275 \):

\( 48 \times 0.275 = 13.2 \)

Answer:

\( 13.2 \)
