Question

World population. The world's population was 6 billion people in 1999. Estimate the world's population in 2099 if it doubles every 45 years

Answer 1

The world's population is estimated to be approximately 48 billion people in 2099, assuming it doubles every 45 years.

Step-by-step explanation:

To estimate the world's population in 2099, we need to determine how many times it will double between 1999 and 2099. Given that it doubles every 45 years, we can calculate the number of doubling periods by dividing the time span by 45: (2099 - 1999) / 45 = 2.22222. Since it's not possible to have a fraction of a doubling period, we round up to the nearest whole number, which is 3.

Now, we can double the initial population of 6 billion three times: 6 billion x 2 x 2 x 2 = 48 billion.

Therefore, the estimated world's population in 2099, assuming it doubles every 45 years, is approximately 48 billion people.

Answer 2

The time difference between 1999 and 2099 is 100 years.

The population doubles every 45 years.

In 100 years it'll double twice.

From 1999 to 2044 and from 2045 to 2090.

The population will be 6 * 4 = 24 billion people and increasing towards 2099.

all the best!
