Question

Please help me with this..
The body mass index,I, can be used to determine an individual's risk for heart disease. An index of less than 25 indicates a low risk. The body mass index is given by the formula , a model, I=700w/h2 (this is a small 2 above the h). Where W=weight, in pounds, and H=height, in inches. Jerome is 68 inches tall. What weights will keep his body mass index between 24 and 32

Answer 1

wasn't this question just asked and answered?

Answer 2

did you not understand the solution I provided? if so, ask what your doubt is

Answer 3

no, I didnt get a reply on this yet..

Answer 4

well, all you need to do is substitute 24 in place of I and 68 in place of h
and find w from the formula.
then you need to substitute 32 in place of I and find w again.
those two values of w will give you the weights that will keep jeromes BMI between 24 and 32

Answer 5

24=175w/1156?

Answer 6

i thought it was 700, not 175

Answer 7

I am confused with this..

Answer 8

it is 24 = 700w/1156
find w

Answer 9

9248/175?

Answer 10

or 6936/175 for w?

Answer 11

6936/175

Answer 12

what do I do from here to find the weights? or is it 175- 189?

Answer 13

no, you did it all wrong.
substitute h = 68 and I = 24, giving you
24 = 700 w/68^2
24 = 700w/4624.
find w from that.

Answer 14

24=175w/1156
that is correct.

Answer 15

you get w = 158.53 pounds.
that is for I = 24
similarly find w for I = 32

Answer 16

161

Answer 17

161? for what?

Answer 18

I=32

Answer 19

that is wrong. do it again.
32 = 175w/1156

Answer 20

211.3?

Answer 21

yes, that is right
