Idk what you mean but maybe try stating it differently
Answer:
0.375
Step-by-step explanation:
go on google and search up "45 divided by 120" then you should have your answer lol
The line y = 8x passes through the origin, which is the point (0, 0).
We say the ordered pair (0, 0) lies on the graph y = 8x.
Answer:
a = 3
b = -9
c = 13
Step-by-step explanation:
3x²-7x + 9 = 2x - 4
3x² - 9x + 13 = 0
a = 3
b = -9
c = 13

Answer:
a) average rate = (total distance)/(total time)
b) Rave = 2·R1·R2/(R1 +R2)
c) cheetah's average rate ≈ 50.91 mph
Step-by-step explanation:
a) Let AB represent the distance from A to B. Let t1 and t2 represent the travel times (in hours) on leg1 and leg2 of the trip, respectively. Then the distances traveled are...
First leg distance: AB = 70·t1 ⇒ t1 = AB/70
Second leg distance: AB = 40·t2 ⇒ t2 = AB/40
The average rate is the ratio of total distance to total time:
average rate = (AB +AB)/(t1 +t2)
average rate = 2AB/(AB/70 +AB/40) = 2/(1/70 +1/40) = 2(40)(70)/(70+40)
average rate = 560/11 = 50 10/11 . . . mph

No equations are given, so we cannot compare what we wrote with the given equations. In each step of the solution, we have used the rules of algebra and equality.
b) For two rates over the same distance (as above), the average is their harmonic mean:
average rate = 2r1·r2/(r1+r2)

c) The cheetah's average rate was 50 10/11 mph ≈ 50.91 mph.
