Question

I need help please if you help here i would really appreciate it.

Answer 1

• 64.9 inches
• 132.3 lbs

Explanation:

You want the height of a 150 lb person with a BMI of 25, and the weight of a 61-inch person with a BMI of 25. BMI is (weight·703/height²).

Height

The equation is already solved for height. You only need to fill in the given numbers:

`H(w)=\sqrt{(703w)/(b)}\\\\H(150)=\sqrt{(703\cdot150)/(25)}\approx\boxed{64.9\quad\text{inches}}`

Weight

Solving the equation for weight, we have ...

`b=(703w)/(h^2)\qquad\text{given}\\\\w=(bh^2)/(703)\qquad\text{divide by the coefficient of $w$}`

Using the given values in this equation, we find the weight to be ...

`w=(25\cdot61^2)/(703)\approx\boxed{132.3\qquad\text{pounds}}`
