Answer:
2½ h
Step-by-step explanation:
Assume the graph is like the one below.
The graph shows how Erin's distance varies with time.
To find out how long it takes Erin to cover 25 mi, find 25 mi on the vertical axis.
From there, draw a horizontal line until it hits the graph.
Then drop a vertical line to the horizontal axis.
It hits half-way between 2 and 3.
It takes Erin 2½ h to run 25 mi.
Z=-y i believe because you have to do z+y
-16t^2 + 1000 > 300
16t^2 < 1000 - 300
16t^2 < 700
t^2 < 700/16
t^2 < 43.75
t < 6.61
Answer:
Step-by-step explanation:the second one
Answer:
The answer would be A.
Step-by-step explanation:
This is because when you divde 120 by 10, you will be given an answer of 12. This shows that 10% of 120 is 12.
