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;
 , we get;

       
Thus, the value of constant is  96.
<u>Time taken:</u>
Substituting  and
 and  in the formula
 in the formula  , we get;
, 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:
$70 each
Step-by-step explanation:
If 4 friends each buy a hat, that would be $50 because that is $12.50X4=%50.00. Then, Since the total is $190 and $50 is off the chart, you would be left with $140 to spend on two t-shirts. Finally, since they are the same price, you divide $140/2=$70. Each t-shirt is $70.

When you square root something’s it’s times by the same number
-1 squared =-1•-1
1•1=1
-•-=+
-1•-1=+1
=1
        
             
        
        
        
OK.  I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.  
But I remembered that
           sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the 
" 1/x " key, and got 11.474, which I knew to be sec(85).
        
             
        
        
        
Answer:
y = 2x+2
Step-by-step explanation:
y = mx+b
     m = slope = 2
     b = y-intercept = 2
