In a 10 m2 ecosystem, there are 60 raccoons. What is the population density of raccoons?6 per m2
10 per m2
20 per m2
40 per m2

Answers

Answer:

The correct answer is option A, 6(Racoons)/(m^2)\n

Explanation:

The Population density of any species in an ecosystem is equal to the number of that species living in one unit of area.  

Thus , population density can be represented as  

(Total population )/(Total area of habitat) \n

Substituting the given values in above equation, we get -

= (60)/(10) (Racoons)/(m^2)\n= 6 (Racoons)/(m^2)\n

The answer is 6 per m2.

A population density is the number of animals per 1 m2.
So, this problem can be solved by using a proportion:
If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.
60 raccoons : 10 m2 = x raccoons : 1 m2
60 raccoons : 10 = x raccoons
x raccoons = 6 raccoons

Thus, the population density is 6 raccoons per m2.

David invested $220 in a savings account that offers a 3% return on the investment. The value of David's investment will be at least $400 after a period of ________ years. Hint: Use the formula A = P(1 + r)t, where A is the amount after t years, P is the amount invested, r is the rate of interest, and t is the time period.
Use a calculator to compute the answer, and round it off to the nearest year.

Answers

Principal amount invested by David = $220
Percentage of interest = 3%
Final amount = $400
Time of investment = t years
Then
A = P(1 + r)^t
400 = 220(1 + 0.03)^t
400 = 220(1.03)^t
(1.03)^t = 400/220
             = 20/11
t = 20.225 years
David's investment will be at least $400 after a period of 20.23 years.
