Answer:
10.4
Step-by-step explanation:
We can use the Pythagorean theorem to solve for the unknown side since this is a right a triangle.
a^2 +b^2 =c^2
where a and b are the sides and c is the hypotenuse
6^2 + x^2 =12^2
36+x^2 = 144
Subtract 36 from each side
36-26+x^2 =144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(108)
x =10.3923
x =10.4  rounding to the nearest tenth
 
        
                    
             
        
        
        
answer : am/b
Step-by-step explanation:
the rate of copying packets = a/b
each packet (a) contains *m* pages
total number of pages in all books together is =a×m 
so the rate of copying of pages = a×m/b
