A plane is flying at 32,460 feet.

To avoid some turbulence, the
plane ascends 1645 feet. It then
descends 3
5
of its new height to
prepare for landing. What are
the heights that the plane will be
at after it ascends to avoid
turbulence and after it descends
to prepare for landing? Select
all that apply.
A. 12,326
B. 13,642
C. 18,489
D. 20,463
E. 30,815
F. 34,105

The answer is B and F

b and f

B and F

I need help on this question too.🥺

Is it really the answer B and F

To solve this problem, we first need to find the height after the plane ascends to avoid turbulence.

Starting with the initial height of 32,460 feet, we add the ascent of 1,645 feet:

32,460 + 1,645 = 34,105 feet

So, the height after the plane ascends is 34,105 feet.

Next, we need to find the height after the plane descends 35% of its new height.

Taking 35% of 34,105 feet:

0.35 * 34,105 = 11,936.75 feet

Subtracting this descent from the plane's new height:

34,105 - 11,936.75 = 22,168.25 feet

Now, we need to round this result to the nearest whole number.

Rounding 22,168.25 feet:

22,168.25 ≈ 22,168 feet

So, after the plane descends, the height is approximately 22,168 feet.

The possible answer choices are:

A. 12,326 - This choice is not correct because it is not equal to the height after the plane ascends or descends.

B. 13,642 - This choice is not correct because it is not equal to the height after the plane ascends or descends.

C. 18,489 - This choice is not correct because it is not equal to the height after the plane ascends or descends.

D. 20,463 - This choice is not correct because it is not equal to the height after the plane ascends or descends.

E. 30,815 - This choice is not correct because it is not equal to the height after the plane ascends or descends.

F. 34,105 - This choice is correct because it matches the height after the plane ascends.

Therefore, the correct answers are:

34,105 (after the plane ascends) and 22,168 (after the plane descends).
