A plane descended 1500 ft. Twenty minutes later, it descended 1400 ft. What is the total change in altitude of the plane relative to its original altitude? Could anyone find the answer to this please it would be really hopeful.

9514 1404 393

  -2900 ft

Step-by-step explanation:

We normally measure altitude as a positive number upward from the ground. Then a descent is a negative change in altitude.

To find the total change in altitude, add the changes:

  (-1500) +(-1400) = -(1500 +1400) = -2900

The change in altitude relative to the original altitude was -2900 feet.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
