<h2>
Answer:</h2>
<u>The mean altitude will be</u><u> -54 per minute</u>
<h2>
Step-by-step explanation:</h2>
We are given with altitude change as -378 feet over 7 minutes
Now
We need feet per minute
So -378 / 7 will give us the altitude change per minute
-378 / 7 = -54
Therefore the mean change of altitude in feet per minute is -54 per minute
Thank you for posting your question here at brainly. Below is the solution:
m(fat) = %fat x 25,5 = 0,37 x 25,5 = 9,435 g of fat
<span>m(protein) = %protein x 25,5 = 0,28 x 25,5 = 7,14 g of protein </span>
<span>m(carbohydrate) = %carbohydrate x 25,5 = 0,04 x 25,5 = 1,02 g of carbohydrate </span>
<span>E = m(protein) x 17 + m(fat) x 38 + m(carbohydrate) x 17 </span>
<span>E = (7,14 x 17) + (9,435 x 38) + (1,02 x 17) </span>
<span>E = 497 kJ</span>
2(2*3 + 3*5 + 2*5) = 2(31) = 62
