Answer:
Ihorangi uses 7.65 litres of petrol to and from work
Step-by-step explanation:
If the car Ihorangi drives consumes 7.5 L/100 km
Then for 1 km journey, the car will consume 7.5/100 L
= 0.075 L
If Ihorangi travels 51 km to work and 51 km from work
Therefore Ihorangi travel (51 + 51) km daily to and from work 
= 102 km daily
The fuel he consumes daily is 102*0.075 L
=  7.65 L
 
        
             
        
        
        
√32x^10y^n simplies to 4x^5y^3√2y
Then n = 7 because √y^7 = √(y^6 * y) = y^3√y
So √32x^10y^7 = 4x^5y^3√2y
Answer
n = 7
 
        
             
        
        
        
Answer: 7.5
Step-by-step explanation:
use pythagorean theorem 
13^2 + b^2 = 15^2 
 - 13^2
b^2 = 56 - square root 
= 7.5
 
        
                    
             
        
        
        
Answer: The value of x and y are 2 and 15 respectively.
Step-by-step explanation:
Since we have given that 
Number of hours available in graphics = 21 hours
Number of hours in printing = 19 hours
Number of hours required by x in graphics = 3
Number of hours required by x in printing = 2
Number of hours required by y in graphics = 1
Number of hours required by y in printing = 1
According to question, we get that 

Using the graphing method, we get that
x = 2 and y = 15
Hence, the value of x and y are 2 and 15 respectively.
