12 + 26 + 125 = 163
163 + 0.056(163) = 163 + 9.13 = 172.13
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
mid point formula = (x1+x2/2 , y1+y2/2)
hence putt the values we get,
mid point = ( -1+3/2 , 7-2/2)
                  = (1 , 2.5)
 
        
             
        
        
        
Answer:
Step-by-step explanation:
1 litre = 1000 ml
water : Sucrose : Saline = 1000 : 269 : 61
This is simplest form. We cannot reduce this as 61 is a prime number and 1000; 269 will not come in 61th table or 
We can say 100 ; 269 ; 61 don't have common term
 
        
             
        
        
        
Million has 6 zeoes
34,000,000+256,00*400
PEMDAS
multiply first
256,000*400=102,400,000
add to 34,000,000
136,400,000
now
must be in form
(x)(10^m)
such taht
1<x<10
and x times 10^m is the original number
1.364*10^8
