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.

Help ASAP pleaseee!
natulia [17]

Answer:

<h2><em>11.6%</em></h2>

Step-by-step explanation:

The probability of getting a 6 is 1/6.  

The probability of not getting a 6 is 5/6

We roll a die 4 times and want 2 sixes, and 2 not sixes.

i.e.exact 2 6's  

We want a combination of 2 sixes from 4 rolls, so we can use the binomial formula to solve this

(4C2)(1/6)²(5/6)² = 6(1/36)(25/36) = (1/6)(25/36) = 25/216 = 0.1157

Nearest tenth of percent is 0.1157×100=11.6%

Ans :11.6%

spin [16.1K]

Answer:

Step-by-step explanation:

-1/6 * -1/5 = 1/30

A negative number times a negative number equals a positive number. When multiplying fractions, the numerators get multiplied over the denominators being multiplied. so -1 * -1 = 1 which is the numerator. 6 * 5 is 30 which is the denominator.
