The stopping distance, d, of a particular car after the brakes are applied varies directly as the square of the rate, r. if the car is travelling 60 mph, it can stop in 200 feet. how many feet will it take the same car to stop when it is travelling 80 mph?

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 !

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

i think the correct option is the second option.
