Answer: 3750 m
Step-by-step explanation:
Remember that there are different units; one is in km and the other is in m
I’ll go from km to m
1 km = 1000 m
Therefore 5 km = 5 x 1000 m
5km = 5000 m
Now, we just subtract to find how much more Suzanne have to run
5000 m - 1250 m = 3750 m
Answer:
B) y=2.75x
Step-by-step explanation:
2.75 is the amount the DVDs cost and x is the number of DVDs Fran buys. So it'll cost her 2.75 for every DVD she buys
Answer: if it's -3 of the regular price you add 3 which would give you 6. Billy is wrong because he only added one to 3
Answer: 50
Step-by-step explanation:
I am rounding it to 1 significant figure.
9.8 = 10 (round up when the last digit is 5, 6, 7, 8 or 9)
5.2 = 5 (round down when the last digit end with 0, 2, 3 or 4)
So it now is 10 x 5 = 50
A) 0 = 100m/s + 2(-9.8)(x_f-0)
x_f = 510
b)
0 = 0 + 100m/s(t) + (1/2)(-9.8)t^(2)
Use the quadratic formula
-200/-9.8 = 20 seconds
