There is a drought and the oak tree population is decreasing at the rate of 4% per year. if the population continues to decrease at the same rate, how long will it take for the population to be a third of what it is? if necessary, round your answer to the nearest tenth. the population will reach a third of its original value in approximately blank years.

27 years

Step-by-step explanation:

To find the population in a future year, use the formula:

where A is the amount, p is the starting population, r is 4% or 0.04, and t is the number of years.

Since the population is decreasing it is subtraction. Here we are finding t, A=1 P =3, and r=0.04.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

a .4y4

hope this !
