Answer:
Nolan's time is 100 seconds.
Step-by-step explanation:
Kong took 85 seconds.
Nolan took x seconds.
Kong took 15% fewer seconds than Nolan, so Kong's time is 85% of Nolan's time.
Kong's time is
85% of x or 0.85x
Kong's time is 85 seconds
0.85x = 85
x = 85/0.85
x = 100
Nolan's time is 100 seconds.
3x - 2 < 12
3x < 12 + 2
3x < 14
x < 14/3
x < 4 2/3......whole-number value = 4
Answer:
8 years
Step-by-step explanation:
100e^(.05t) = 150 . . . . . a better model of the situation
e^(.05t) = 150/100 . . . . divide by 100
0.05t = ln(1.5) . . . . . . . . take natural logs
t = ln(1.5)/0.05 ≈ 8.11 . . . . divide by the coefficient of t
