Answer:
about 340,000
Step-by-step explanation:
In 10 years, the population dropped to 0.88 of what it was in 2010. At the same rate, in 20 more years, it will drop to 0.88² of what it was in 2020:
2040 population = 440,000·0.88² ≈ 340,000
Answer:
about 340,000
Step-by-step explanation:
In 10 years, the population dropped to 0.88 of what it was in 2010. At the same rate, in 20 more years, it will drop to 0.88² of what it was in 2020:
2040 population = 440,000·0.88² ≈ 340,000

<h3>
Answer: 20 minutes.</h3>
Work Shown:
Estimate = 1.25*(actual time)
Estimate = 1.25*(16)
Estimate = 20
Bryan estimated it would take 20 minutes.
Note: The multiplier 1.25 represents an increase of 25%
