Answer:
40,000 workers
Step-by-step explanation:
This question deals with simple rates proportion.
If it takes 20 years for X workers to complete a job,
if we double the amount of workers, we will take half the time.
hence to halve the time from 20 years to 10 years, we will need to double the amount of workers.
In this case we will need 20,000 workers x 2 = 40,000 workers
So she started at 12 and ended at 14
14-12=2
she traveled for 2 hours
50miles per hour or 50m/h
(m=miles not minutes)
2 hours so
2h times 50m/h
100miles traveled
5000(1+.07)^2
5000(1.07)^2
5000(1.14)
5,700
Your final answer should be 5,700$. If you wanna double check you would use the equation fv=bv(1+r/m)^mt
Um what. This doesn’t make sense. Your not even asking a question
She would have done 512 jumping jacks on the 10th day.
