3km times 3 = 9km. 9km equals to 9000m.
4 is a because 2x=6 can simple to x=3
and 5 is x=30
Answer for the first dropdown box is CAF and EFH
Answer for the second dropdown box is because they are corresponding angles of parallel lines cut by a transversal
Answer for the third dropdown box is transitive property of congruence
------------------------------------------------------------------------------
Explanation:
Angles CAF and EFH are corresponding angles because they are on the bottom side of the parallel lines, and on the right side as well. So they are congruent (due to the lines being parallel).
Since CAF = EFH and EFH = HFD, this means that CAF = HFD
It's similar to saying if x = y and y = z, then x = z. Think of it as a connecting chain. This is the transitive property.
Given is the Overhead charges = 25 dollars.
Making charge of each barrette = 1.25 dollars.
Let's assume the number of barrette that she makes = x
So the Cost function would be, C(x) = 1.25x + 25.
She sell each piece for 3.50 dollars.
So the Revenue function would be, R(x) = 3.50x
We know the Profit function is given by the difference of Revenue function and Cost function.
Profit function = Revenue function - Cost function
P(x) = R(x) - C(x)
P(x) = 3.50x - (1.25x + 25)
P(x) = 3.50x - 1.25x - 25
P(x) = 2.25x - 25
Hence, Marie's Profit would be P(x) = 2.25x - 25.
