10. How I would solve it, is I would convert them into decimals so it is 7.5/.75.
Answer:
area of a semicircle is (pi * r^2)/2.
Step-by-step explanation:
1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Answer:
first one
28.26 im not 100% correct i dont think
(7*4)3n is the algebraic expression:)
