Given that the amount of time varies inversely with G.
It can be written as,

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
, we get;


Thus, the value of constant is 96.
<u>Time taken:</u>
Substituting
and
in the formula
, we get;

Thus, the time taken to put out the fire using 200 gallons of water is 48 minutes.
Hence, Option B is the correct answer.
Answer: The proportion that will qualify is 0.0314 or 3.14%.
First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.
(128 - 141) / 7 = -1.86
Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.
Not sure what you’re trying to find but here’s the simplified version:
-4<=2t+5<11
-9<=2t<6
-9/2<=t<3
number 3 is not congruent but number 4 is because #4 is basically the same thing but you cant really multiply something to question #3 to get those answers.
The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.
