54 - 30 = 24
Take the orginal number and place on the bottom
The orginal number is 30
24/30, if you need to simply find this number it will be 4/5
When you divide 4/5 it will be .80 or 80%
5 divide by 4 is equal to 
 Answer: 80%
 Hope this help
        
             
        
        
        
4/7 × 3/4
(4 and 4 are cancelled )
7×3
the answer is 21
        
             
        
        
        
$855 but you also have to add the 20 near ball pizzas times however much they were but you must have skipped that by accident 
        
             
        
        
        
We know, widest angle is always opposite to the largest side of the triangle, as largest side is 50 here (which is backward to house) so largest angle would be opposite to it. So, that corner will be touched by  Fence A & B
"Proportionality Theorem" compares the sides of the same triangle 
Here, According to that theorem, 
ST / RS = UT / PU
If FG is an altitude, then <DFG  is an right triangle.
In short, Your Answer would be Option B
For last question here, remember, longest side must be greater than either side, and must be smaller than sum of those smaller sides.
        
                    
             
        
        
        
I honestly don't know if this is correct but it might be i think its the middle one y=f(x)=x to the second power
