Answer:
C
Step-by-step explanation:
Remark
You must do the changes in order. Add 1 then multiply by 2
- First entry: 6
- Add 1: 6 + 1 = 7
- Multiply by 2 = 2*7 = 14
- Add 1: 14 + 1 = 15
- Multiply by 2: 15 * 2 = 30
Answer: 7 14 15 30
Answer:
12.5 s
Step-by-step explanation:
If acceleration is constant, speed is proportional to time. To increase the speed by 50 km/h, the car will need an additional time given by ...
t/(50 km/h) = (20 s)/(80 km/h)
t = (20 s)(50/80) . . . . . multiply by 50 km/h
t = 12.5 s
It will take 12.5 more seconds for it to reach a speed of 130 km/h.
Solve for N by simplifying both sides of the equation, then isolating the variable.
N=700
