A population numbers 508 organisms initially and increases by 6.2% each year.Suppose P represents population, and t the number of years of growth. Write an exponential model to represent this situation.

Answers

Answer 1

Answer:

To find the population after t number of years, multiply the starting population by 1 plus the percent increase raised to the number of years.

The equation would be: P = 508(1.062)^t

21/8 as a mixed number

Answers

divide 21 by 8. and then whatever the reminder comes will go as the whole number
and the reminder will be the numerator and the number 8 will be the denominator.
the answer is 2 5/8
2 is the whole number, 5 is the numerator and 8 is the denominator

Hope this helps!

Well, all you would have to do is divide 21 into 8, (21 divided by 8), and the remainder will become your new numerator, and the divisor, (8), will be your denominator, and the whole answer will be your whole number, so your mixed number will be 2 5/8, because 21 divided by 8 = 2, 2 times 8 = 16, 21 - 16 = 5, 2 is your whole number, 5 is your numerator, and 8 is your divisor. =)

Answers

1 cubic centimeter = 1 milliliter, so your 8cm cube is 8x8x8 = 512 cubic centimeters.
This would equate to a volume of 512 milliliters which is equal to just over 1/2 liter (0.512 liters).

Mike sees 3 more fish than Chris. Chris sees 6 fish. How many fish does Mike see? It says use comparison bars. Thanks

Answers

Chris sees 6 fish.

Mike sees 3 more fish than Chris.

6 + 3 = 9

So on your bar, you have Chris's number of fish he saw, 6, and you have 3 being added to that on Mike's bar.

Mike sees 9 fish. 6 + 3 = 9.
