Because the area of a trapezoid is A= ((a+b)/2)h, where a is the length of the top, b is the length of the base, and h is the height, you plug that in to find your answer.
This trapezoid is sideways, but the top of it is 7m (which is a) and the base is 10 m (which is b), add a and b to get 17, A = ((17)/2)h
Now divide by 2 to get A = (8.5)h
Because the height is 9, A = (8.5)9 = 76.5
The area of the trapezoid alone is 76.5m
The answer is D: (6, -13)
Step by step:
X is translated 2 units to the right
Y is translated 8 units downs
Substitute 4 for the x value to
Substitute -5 for the y value
( (4) + 2, (-5) - 8 )
4+2=6
-5-8= -13
Answer: (6, -13)

62.25 + 1 - 1 cause that's just 62.25 + 0 which is 62.25
Answer: 
Step-by-step explanation:
Let d be the distance from Nadia's home to the grocery store.
Given : Nadia traveled uphill to the grocery store for 30 minutes at just 4 mph.
∵ 1 hour = 60 minutes.
Then, 
Since 
Then, 
Also, She then traveled back home along the same path downhill at a speed of 12 mph.
Then, Time taken to travel back home = 
Average Speed =

Hence, her average speed for the entire trip from home to the grocery store and back =
