Question

The body mass index, I, can be used to determine an individual's risk for heart disease. An index less than 25 indicates a low risk. The body mass index is given by the formula, or model, I = 700W/H^2, where W = weight, H = height, in inches. Francis weighs 209 pounds and stands 70 inches tall. What is his approximate body mass index? Find an inequality describing all weights W that Francis can have and be in the low-risk category.
Francis' approximate body mass index is? (round to the nearest whole number).

Answer 1

And the 2nd part of the question would be to find an inequality describing all weights that Francis can have to stay in the low-risk category.

Answer 2

1st part (700*209)/70^2

Answer 3

I just got that far..LOL

Answer 4

I think the answer is 30.

Answer 5

lol bmi<25 correct?
hence (700*w)/h^2<25

Answer 6

however height remains the same

Answer 7

w<25*(70)^2

Answer 8

his current bmi is 30 I believe when dividing 146300 by 4900. then I am lost.

Answer 9

w<[25*(70)^2/700]

Answer 10

i think he can have a weight up to 175 pounds

Answer 11
