If it takes 5 years for an animal population to double, how many years will it take until the population

muminat

9514 1404 393

Answer:

7.92 years

Step-by-step explanation:

We want to find t such that ...

3 = 2^(t/5)

where 2^(t/5) is the annual multiplier when doubling time is 5 years.

Taking logs, we have ...

log(3) = (t/5)log(2)

t = 5·log(3)/log(2) ≈ 7.92 . . . years

It will take about 7.92 years for the population to triple.

Hey there! :)

Answer:

29/28.

Step-by-step explanation:

Starting with:

$\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =$

Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:

$\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =$

Add the fractions:

$\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}$

Therefore, the fractions sum up to 29/28.
