Step-by-step explanation:
The student made a mistake in Line 1: AC=2, DF=2 AC ≅ DF .
Answer:

Step-by-step explanation:
The volume V of the fountain is equal to:
V = L*W*h
Where L is the lenght of the fountain, W is the width of the fountain and h is the high of the fountain
We already know that h is equal to x. On the other hand, if we cut a square with side of length x, L and W are calculated as:
L = 18 - 2x
W = 12 - 2x
So, replacing L, W and h on the equation of the volume, we get:
V = (18-2x)*(12-2x)*x
Finally, simplifying the function we get:


25% of 80 is 20 so it is 60. 10% of 60 is 6 so the price is 54.
It takes 2 hours to meet
A to B is 100 miles
A has 30 mph: after 2 h has made 60mph
B has 20 mph: after 2 h has made 40 mph
60+40=100 miles
