Question

use the spreadsheet to answer the following questions.
compute the body mass index for the following people.
a. weight 165 lbs, height 5 feet 4 inches
b. weight 203 lbs, height 5 feet 9 inches
c. weight 255 lbs, height 6 feet 2 inches
b. the body mass index of the second person is 30.7.
(round to the nearest tenth as needed.)
c. the body mass index of the third person is
(round to the nearest tenth as needed.)

Explanation:

Step1: Convert height to inches

The height is 6 feet 2 inches. Since 1 foot = 12 inches, 6 feet is \( 6\times12 = 72 \) inches. Then add 2 inches, so total height in inches is \( 72 + 2=74 \) inches.

Step2: Use BMI formula for imperial units

The formula for BMI in imperial units (pounds and inches) is \( \text{BMI}=\frac{\text{weight (lbs)}}{\text{height (inches)}^2}\times703 \). The weight is 255 lbs and height is 74 inches. First, calculate the square of height: \( 74^2 = 74\times74 = 5476 \). Then, calculate the fraction \( \frac{255}{5476}\approx0.046567 \). Then multiply by 703: \( 0.046567\times703\approx32.7 \) (rounded to the nearest tenth).

Answer:

32.7
