Teresa gave away 8 baseball cards and has 4 left. 8 plus 4 means she originally had 12. Right now she has 4 out of her original 12 cards remaining. This gives us 4/12. We can simplify this by dividing our greatest common factors. 4 goes into both parts of our fraction, when we divide each part by 4 we end up with 1/3. Since we are unable to simplify this problem any further, this means our solution and fraction is 4/12 aka 1/3.
Answer:
Step-by-step explanation:
Given that the dollar cost of producing x appliances is
A) Average cost can be obtained by dividing c(x) by units = x
i.e. average cost = 
B) Marginal cost = dC/dx = 
When x=140 marginal cost 
C) We calculate
c(140) = 
c(141) = 
Marginal cost = difference = 33.80
Same as 34 shown in marginal cost.
Step-by-step explanation:
N:2 = 15:5
N\2 = 15\ 5
Now cross multiply,
5N = 30
N = 6
