Answer:
23.1567
Step-by-step explanation:
710000(1+1.49/100)ⁿ=1000000
710000×1.0149ⁿ=1000000
1000000÷710000=1.0149ⁿ
1.4084507=1.049ⁿ
log1.4084507=ⁿlog1.0149
log1.4084507/log1.0149=ⁿ
Answer:
5r + 3s ≥ 30
Step-by-step explanation:
We know Keiko wants to do exercise at least 30 minutes a day, and she wants ideally to mix up the activities, by combining running and swimming into her schedule.
Since each lap she runs takes 5 minutes and each lap she swims takes 3 minutes, these will be the left side of the inequality:
5r + 3s
She wants to exercise at least 30 minutes a day, so...
5r + 3s ≥ 30
she could do 3 laps of running and 5 laps of swimming for example.
