<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

Hello!
In an isosceles trapezoid, both angles on each side of the base are congruent.
∠z ≅ 75°
∠y ≅ ∠x
Because of this, we can get the angle measure for z easily:
m∠z = 75°
Okay, so the first thing you need to do is find the difference.
64.19 - 59.99 = 4.20
So the percentage is determined by dividing that difference by the cost of the item originally:
4.20 / 59.99 = about .07
Next, you change this number to a percentage by moving the decimal to the right two spaces, so that would be 7%.
Therefore, the sales tax in the area is 7%.
