The length of the hypothenuse or the value of x is equal to 19.53
Data;
- hypothenuse = x
- adjacent = 11.2
- opposite = 16
<h3>Pythagoras's Theorem</h3>
To solve this problem, we have to use Pythagoras's theorem which is used to find the missing side in a right angle triangle if we have at least two sides.
The formula for this is 

Let's substitute the values and solve for the missing side

Step-by-step explanation:
We know that for foreign-made vehicles imported into the U.S., whether new or used, either for personal use or for sale, are generally dutiable at the following rates: Cars: 2.5%.
From task we know that the  Fiat car abroad that cost him $6,250.
We have the following proportion:

The duty he has to pay is  156.25$.
 
        
             
        
        
        
You need two equation to solve for two variables exactly.
Using this one equation alone y=15-8x.
Do you have another equation?
 
        
             
        
        
        
Answer:
 The exact charge per cubic foot of water usage is 4 Cents.
Step-by-step explanation:
Let the per cubic foot charge be $ 'x' and the fixed charge be $ 'y'.
A household using 1100 cubic feet was billed $ 114.
Therefore, we get the equation, 
 .......( A )
.......( A )
And other household 1500 cubic feet was billed $ 130.
Therefore, we get the equation,
 ......( B ).
 ......( B ).
Now, we subtract equation A from  equation B.
 .....( B )
.....( B )
 ......( A )
 ......( A )
