Answer:
AB = 142
Step-by-step explanation:
If M is the midpoint, then AM = MB
6x+5 = 7x -6
Subtract 6x from each side
6x-6x+5 = 7x-6x -6
5 = x-6
Add 6 to each side
5+6 = x-6+6
11=x
We want to find AB
AB = 6x+5+7x-6
AB = 13x -1
      = 13(11) -1
      =143-1
      = 142
 
        
             
        
        
        

So, Option C is correct.
Step-by-step explanation:
We need to find Volume of cone.
We are given:
π = 3.14
Length = 27 cm
Diameter = 15 cm
The formula used to find Volume of cone is:

We are given diameter but we need radius in the formula
So, Radius = Diameter/2 = 15/2 = 7.5 cm
We need to find height of cone.
Using Pythagoras theorem:

So, Height of cone = p= 25.93
So, r= 7.5 and h= 25.93 and π = 3.14
Putting values in the formula:


Rounding off to the nearest tenth:

So, Option C is correct.

Basically, the unit rate is 1.99/18 or 0.110. 
If we round 1.99 to 2.00, we instead get 0.111~
        
             
        
        
        
Answer:
20% 
Step-by-step explanation:
12 bottle is 60 rupees 
each sold 6 ruppes
