Answer:
(10, 0)
Step-by-step explanation:
(x2 + x1/2 , y2 + y1/2)
[10 + 10 / 2 , 1 + (-1) / 2]
(20/2 , 0/2)
(10, 0)
Answer:
The volume of the prism is 300 cubic inches not 300 square inches
Step-by-step explanation:
we know that
The volume of the prism is equal to
where
B is the area of the base
h is the height of the prism
we have
substitute
therefore
The volume of the prism is 300 cubic inches not 300 square inches
Use distance = rate x time
18 minutes is 3/10 of an hour.
So the distance to the store is:
d = 20*(3/10) = 6 miles
The distance downhill is the same, 6 miles. So:
6 = (60)t
6/60 = t
1/10 = t
Where t is the time it took to go back home. So t is .1 hour (6 minutes).
To calculate average speed we use the formula:
average speed = total distance/ total time
average speed = (6+6)/(.3 + .1) = 12/(.4) = 30
So her average speed for the entire trip is 30 mph (miles per hour).
