Lainey rides a ski lift down the mountain. Her elevation change is -3,430 feet at a rate of -490 feet per minute. How long will it take Lainey to travel from the top of the ski lift to the bottom of the ski lift?

7 minutes

Step-by-step explanation: For this problem we want to know how many minutes will it take Lainey to travel from the top of the ski lift to the bottom of the ski lift.

Simply divide -3,430 by -490.

-3,430/-490 = 7

The answer will be positive because when dividing two negative numbers, your answer will always be positive.

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 !
