Answer:
h = 2 ft
Step-by-step explanation:
V = lwh
144 = (9)*(8)*(h)
144 = (72)*h
h = 144/72
h = 2 ft
 
        
             
        
        
        
Answer:
£170000
Step-by-step explanation:
In 2010, Rafik bought a house. Let us assume Rafik bought the house for $x.  In 2015, Rafik sold the house to Bianca and made 20% profit. 20% profit = 20% of x = 0.2 × x = 0.2x. Therefore Rafik sold the house to Bianca at x + 0.2x = 1.2x. Bianca bought the house at 1.2x
The house was sold by Bianca at 5% loss in 2019. 5% loss = 0.05(1.2x) = 0.06x
Therefore the house was sold by Bianca at 1.2x - 0.06x = 1.14x. Since Bianca sold the house at £193800.
⇒ 1.14x = 193800
x = 193800/1.14
x = £170000
Rafik paid £170000 for the house in 2010
 
        
             
        
        
        
Answer:
x=16
Step-by-step explanation:
this is the good ol' a^2 + b^2 = c^2
c is always the longest line, in this case 20. 
so now you have 12^2 + b^2 =20^2 or 144+b^2=400.
subtract 144 from each side. B^2=256.
then you square root each side and you are left with b=16 and in this case B=X
 
        
                    
             
        
        
        
Answer: 27-c =x
Step-by-step explanation:
We'll use c to represent the amount taken away (subtracted) and x to represent the amount left (the answer). 
We begin with 27 balloon, and take away c amount to make x. 
27-c =x
