Answer:
4.5 gallons.
Step-by-step explanation:
Multiply the volume value by 4. 
In this case, you multiple 4.5 by 4 which equals 18.
4.5 gallons = 18 quarts
 
        
                    
             
        
        
        
Answer:
Supplementary angles
x = 31
Step-by-step explanation:
Since, (3x + 25)° and 2x° are straight line angles. Therefore they are supplementary angles
(3x + 25)° +  2x° =180°
(5x + 25)° = 180°
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155/5
x = 31 
 
        
             
        
        
        
Answer:
$5 per adult and $3 per kid
Step-by-step explanation:
5x10=50
3x3=9
50+9=59
4x5=20
3x3=9
20+9=29
 
        
             
        
        
        
  volume of A = 1728
volume of B = 729   
<span> (1728 / 729) = (a / b)^3  (a = width of A, b = width of B)
  a / b = cube root (1728 / 729)  = 4/3   </span><span> b = 10 (given) 
 a / 10 = 4/3 </span><span>
  a = 40/3 = 13.33333</span> 
 so width of A is 13.33m
