Answer:
The answer is c
Step-by-step explanation:
When there is a division with the sae variable and different exponent, you substract the exponent from the denominator from the one in the numerator.
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
Answer:
43
Step-by-step explanation:
First, 2014 seconds goes to about 33 minutes. 24 hours to minutes, divided by 33, gets you to 43. hope this helps
I answer this question atleast once a day hahah.
Firstly convert 1/2 into quarters.
1/2 = 2/4 (double the numerator and denominator)
Then add the two, 2/4 + 1/4 (add the numerators)
2/4 + 1/4 = 3/4
The answer is: 3/4
