What formula would i use to solve:
If the earth has an annual growth rate of 1.2% how many people are added to the earth each year? what will be the population of earth in 2050?
thanks, any help is appreciated!! :D
To solve this problem, you would need to use the formula for population growth:
Population = Initial Population * (1 + Growth Rate)^Number of Years
Let's break it down step by step:
1. Calculate the number of people added each year:
To find the number of people added each year, you need to calculate 1.2% of the current population. This can be done by multiplying the current population by 0.012 (1.2% in decimal form).
Number of People Added = Current Population * Growth Rate = Current Population * 0.012
2. Calculate the population in 2050:
To find the population in 2050, you need to add the number of people added each year to the current population for the number of years that will pass between now and 2050. Since we don't have the current population, we will assume it to be a known value, let's say X.
Population in 2050 = X * (1 + Growth Rate)^Number of Years
You would need to know the current population of the Earth to get an accurate answer for the population in 2050. Without this information, it is not possible to determine the exact population for that particular year.
However, if you have the current population, you can substitute the values into the formula and calculate the population in 2050.
