Answer:
   1 : 12 : 4
Step-by-step explanation:
Let A, G, C represent the ages of Alex, George, and Carl, respectively. We are told that ...
   A = G +12
   C = 3A . . . . . . . we read this as "3 times as old"; not "3 times older"
   A + G + C = 68
Substituting for G and C, we have ...
   A + (A -12) +(3A) = 68
   5A = 80 . . . . . add 12
   A = 16 . . . . . . . divide by 5
The other ages are then ...
   G = A-12 = 16 -12 = 4
   C = 3A = 3·16 = 48
The ratios are ...
   G : C : A = 4 : 48 : 16
   G : C : A = 1 : 12 : 4

Answer:
Step-by-step explanation:
Given that a firm has  a price of $5, an average total cost of $7, and an average variable cost of $4
Price = 5
Var cost = 4
Contribution = 1 dollar per unit
Since contribution is positive, there is scope for getting profit by increasing production.
In the short run, you should __operate______(operate/shut down) because __Price______exceeds ________ average variable cost price . In the long run, you should __exit______(stay in/exit) the market because ________ average total cost price exceeds____price.______average variable cost price average total cost 
 
        
             
        
        
        
The three inside angles of a triangle need to equal 180 degrees.
 To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
