Answer:
standard showerhead in Andrew's house dispenses 8 gallons of water per minute. Andrew changed this shower head to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new shower head.
y = 3x
 
        
                    
             
        
        
        
Step-by-step explanation:
12. Cos 60° = 8/c
 0,5 = 8/c
 0,5 c = 8
 c = 16
 D² = V16²-8²
 = V256-64
 =V192 = V16×12 = 4V12 
 = 4V4×3 = 8V3
13. Cos 30° = 6/b
 V3/2 = 6/b
 V3 b = 12
 b = 12/V3
 b/Sin B = a /sin A
 b/Sin90° = 6/ sin 60°
 <u>b</u> = <u> </u><u> </u><u> </u><u>6</u><u> </u><u> </u><u> </u>
 1 V3/2
 b× <u>V3</u> = 6
 2
 b = 6× 2/V3
 = 12/V3
 
        
             
        
        
        
3.22 divided by 14 is .23.   .23 plus .15 is .38 cents per candy at regular price.

Step-by-step explanation:
Answer: Step-by-step explanation: We are given an exponential equation.We need to convert it into it's equivalent equation.Let us factor 4.4 = 2 × 2Therefore, 2 × 2 could be written as .Now, let us factor 64 in terms of 2's.64 = 2 × 2× 2× 2× 2× 2 = .Replacing 4 by  and 64 by  in original equation, we get Distributing 2 over (x+3), we get
