The annount of time (in minutes) that it takes to put out a fire varies inversely
sveticcg [70]

Given that the amount of time varies inversely with G.

It can be written as,

T G=K

where K is the constant.

We need to determine the time it takes to put out the fire when 200 gallons of water are used.

<u>The value of constant:</u>

When G=8, T=12 , we get;

(12)(8)=K

      96=K

Thus, the value of constant is  96.

<u>Time taken:</u>

Substituting G=2 and K=96 in the formula T G=K, we get;

T(2)=96

    T=48

Thus, the time taken to put out the fire using 200 gallons of water is 48 minutes.

Hence, Option B is the correct answer.

How do i answer this and how do i find the modal
faltersainse [42]
So firsty up, you need to have equal denominators IN order to do this equation.

 1/3 and 5/12..

3x4=12

So the rule when changing denominators, you multiply 4 intop, so it will become 4/12, and 5/12 + 4/12 = 8/12, and,

8/12 + 1/12= 9/12 and 9/12 simplified is 3/4..

So the answer is 3/4.

Hope this helped.
