Answer:
75 % of 12 = (75 * 12 ) / 100 = 9 were sold
12 - 9 = 3 were thrown out
Step-by-step explanation:
 
        
             
        
        
        
I don't believe so, last time i checked for two lines to be perpendicular they needed to have opposite reciprocal slopes.
For Example
If one line has a slope of 5
The second line has to have a slope of -1/5 
        
             
        
        
        
The only ones that would work are if the factor is composite and if 1 is added to it it can be divided into 48. So 15 would work. The factor 15 is composite, and if 1 is added it can be divided into 48.Therefore the son is 15.
        
                    
             
        
        
        
Area = 1/2*a*P
(a = apothem , P= Perimeter)
P = Sum of all sides
   = 12*8
   = 96
Area = 1/2*30*96 = 1440
Hope this helps!
        
             
        
        
        
I think you would multiply 223 with 15 then divide that number with 792. That’s what I’m guessing
