Answer:
0.84
Step-by-step explanation:
4x2+13a+10=7
13a=7-10-8
13a=-11
a=-11:13
a=0.84
I think the answer is 10.3%
Answer:
Step-by-step explanation:
![\displaystyle a^2 + 2a\sqrt{\frac{a^2}{4} + h^2} = S.A. \\ \\ 14^2 + 2[14]\sqrt{\frac{14^2}{4} + 19^2} = S.A. \\ \\ 196 + 28\sqrt{\frac{196}{4} + 361} ≈ 762,9567885 ≈ 762,96](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%5E2%20%2B%202a%5Csqrt%7B%5Cfrac%7Ba%5E2%7D%7B4%7D%20%2B%20h%5E2%7D%20%3D%20S.A.%20%5C%5C%20%5C%5C%20%2014%5E2%20%2B%202%5B14%5D%5Csqrt%7B%5Cfrac%7B14%5E2%7D%7B4%7D%20%2B%2019%5E2%7D%20%3D%20S.A.%20%5C%5C%20%5C%5C%20196%20%2B%2028%5Csqrt%7B%5Cfrac%7B196%7D%7B4%7D%20%2B%20361%7D%20%E2%89%88%20762%2C9567885%20%E2%89%88%20762%2C96)
I am joyous to assist you anytime.
I would say c.15
Because I said so
BMI = (pounds * 703) / (height^2)
so in the information you are missing the height
let's find it :)
first plug in what you know:
28.5 = (211 * 703) / (height)^2 then solve for (height)
28.5 (height)^2 = (211 * 703) multiplied both sides by (height)^2
(height)^2 = (211 * 703) / 28.5 divided both sides by 28.5
(height) = square root [(211 * 703) / 28.5] square rooted both sides
(height) = 72.143 inches
The healthy BMI is about 25
so 25 = (pounds)(703) / (72.143^2)
25(72.143^2) / (703) = (pounds) divide by 703, multiply by (72.143^2)
pounds = 185
211 - 185 = 26
Therefore Christopher would have to lose 26 pounds.
*Note: If the BMI you wanted to use was not 25, then just replace it like this
(pounds) = (BMI)(72.143^2) / (703) = goal weight
