The population of Neverland was 2.3 billion, one hundred years ago. Currently the population is 3.2 billion. What will this population be 100 years from now?

4.448 billion

Step-by-step explanation:

What we must calculate is the proportion of increase in the period of 100 years, we know the one of 100 years ago and the current one, therefore we can calculate this increase.

Current population / Old population = 3.2 / 2.3 = 1.39

The increase is 1.39, which is equal to a 39% increase in the population.

Now to calculate how much it will be in 100 years, it would be to increase the current population by 39% and this will give us an estimate of this population in 100 years.

3.2 * 1.39 = 4.448

This means that the population within 100 years will be 4.448 billion

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

cut 138 centimeters off

step-by-step explanation:

250-112 = 138
