Answer:
The 12000 City would become 22,986 people, while the 230,000 city would become a population of 124,223.
Step-by-step explanation:
1st Part:
=12000⋅(0.026000000000000002⋅25)
=12000(2.718281828459045)(0.65)
=22986
2nd Part:
=230000⋅(−0.044000000000000004⋅14)
=230000(2.718281828459045)(−0.616)
=124223
Using proportions, it is found that it will take you 392 seconds = 6 minutes and 32 seconds to complete 4 laps.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, considering the given rates, the time that is takes to complete one lap of 400 m is given by:
t = 2 x 12(sprint) + 24(half as fast as the sprint, 24 seconds per 100 meters) + 50 = 98 seconds.
Hence for 4 laps, the time is given by:
t = 4 x 98 seconds = 392 seconds = 6 minutes and 32 seconds to complete 4 laps.

Answer: Choice B) 3 years
--------------------------------------
Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3

Jacobs unit rate is 1/5 of the wall every 6 minutes which is .033 repeating of the wall every 1 minute
sorry I don't know the answer but i hope you get well soon
