Answer:
14/25
Step-by-step explanation:
All percentages can be represented by PERCENTAGE/100
So 56% is 56/100
Then simplify by dividing by 2
28/50 Then simplify again by 2
14/25
 
        
                    
             
        
        
        
Step-by-step explanation:
7.50= (1 + x/100 ) × 5.50
7.50/ 5.50 = 1+x/100
x/100 = 0.36
x= 36.36%
 
        
             
        
        
        
Answer:
x=6.09cm
Step-by-step explanation:
Working out AB:
7.5²+4.9²
= √80.26
AB= 8.96cm
To work out x:
AB is the opposite, where BC is the adjacent. This means that we have to use TOA.
x=8.96/Tan(55.8)
x= 6.09cm
 
        
                    
             
        
        
        
10/5 = 1/x
cross multiply
10x = 5
x = 5/10
x = 1/2...u need 1/2 gallon per fish
