An airplane is flying at an altitude of 4000 feet and descends at a rate of 200 per minute. determine whether the altitude is proportional to number of minutes. explain your reasoning

The correct answer is:

Yes, it is proportional.

Explanation:

In this relationship, we can write the equation for altitude as y = 4000-200x, where y is the altitude and x is the number of minutes.  For every minute that the plane is in the air, the altitude changes the same number of feet; this means it is a proportional relationship.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
