Answer:
The correct answer Is that saw 75 movies last year.
Step-by-step explanation:
To solve this problem, we can write an equation. Let N equal the number of movies that he saw last year and we have:
N x (0.8) = 60
If we divide both sides by 0.8, we will get 75 for N.

I don't see any pattern but if there has to be then it could be that the temperature is increasing and never dropped down.
EF = 15 cm.
Step-by-step explanation:
Step 1:
If the quadrilaterals, ABCD and EFGH are similar their side lengths will be of the same ratio throughout.
Comparing the quadrilaterals, we have AB and EF are similar, BC and FG are similar, CD and GH are similar, DA and HE are similar.
So the ratio of all these sides will be equal.
Step 2:

Of these lengths, we only have the values for AB, BC, CD, DA, GH, HE and need to determine the length of EF. By substituting the known values the ratio becomes;


So
cm. Which is the second option.
