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.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
