(1/12)X = 6800
6800/ (1/12) = X
X = 81600 (hours)
6800 (6.8 * 10^3) divided by 1/12 (12^-1) equals 81600. It will take 81600 hours for the pool to completely empty at a rate of 0.833333333 or 12^-1 gallons per second.

Step-by-step explanation:
Hello There!
The angle labeled 6x is a right angle 
If an angle is formed using the diameter of a circle then the opposite angle of that side is a right angle 
So 6x = 90
isolate the variable 
divide each side by 6 
90/6= 15
6x/6=x
we're left with x = 15
 
        
                    
             
        
        
        
The radius of the circle is 1. 
 
        
                    
             
        
        
        
Answer:
D. f(-3) = 11
Step-by-step explanation:
When f(x) is divided by x+3, you get a quotient g(x) and a remainder of 11:
f(x) / (x + 3) = g(x) + 11 / (x + 3)
Multiply both sides by x+3:
f(x) = g(x) (x + 3) + 11
Substitute -3 for x:
f(-3) = g(-3) (-3 + 3) + 11
f(-3) = g(-3) (0) + 11
f(-3) = 11
