It would be 90%..... 45/450= 10%.... so there would be 90% not being used.
        
             
        
        
        
Unless you show a picture, its impossible to solve.

 Answer with Step-by-step explanation:

So in this sequence,
1st term = 7
2nd term = 10
3rd term = 13
4th term = 16
10th term = 34

In this sequence,
1st term = -1
2nd term = 3
3rd term = 7
4th term = 11
10th term =35
 
        
             
        
        
        
It’s B 
If y-x=6
 Y +X =_10 
then y= 6 + x, instead of y insert this no 
6+ x+ x =-10
6 + 2x =-10 then collect like terms 
2x =-10-6
2x=-16 then multiple both side by 1/2
X=-8 
Y=6+x instead of x insert -8
Y=6-8
=-2
