The time it takes to deflate the air out of a spherical balloon is inversely proportional to the rate at which the air is released. the balloon can be deflated in 70 minutes when the air is released at a rate of 400 cubic centimeters per minute. how long will it take to deflate the balloon if the air is released at a rate of 350 cubic centimeters per minute?

Time taken = 80 minutes.

Step-by-step explanation:

The time it takes to deflate the air out of a spherical balloon is inversely proportional to the rate at which the air is released.

Let t be the time to deflate the air out of a spherical balloon and r be the rate at which the air is released.

We have

The balloon can be deflated in 70 minutes when the air is released at a rate of 400 cubic centimeters per minute.

We need to find how long will it take to deflate the balloon if the air is released at a rate of 350 cubic centimeters per minute

Dividing both equations

Time taken = 80 minutes.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
