To find the answer, you set up an equation:

You put the 20% into decimal form by sliding the decimal place two spaces to the left. The "x" represents the grizzly bear's normal heart rate.

10 = .20x

Now, you divide both sides by .20

You should get:

50 = x

A grizzly bear's normal heart rate when it is not hibernating is 50 beats per minute.

lisabon 2012 [21]

Answer:

<em>Mrs. Adams will earn $3,120 of interest at the end of year 8.</em>

Step-by-step explanation:

<u>Simple Interest</u>

In simple interest, the money earns interest at a fixed rate, assuming no new money is coming in or out of the account.

We can calculate the interests earned by an investment of value A in a period of time t, at an interest rate r with the formula:

I=A.r.t

Mrs. Adams deposited an amount of A=$12,000 into an account that earns an annual simple interest rate of r=3.25%. We must find the interest earned in t=8 years. The interest rate is converted to decimal as:

r=3.25/100=0.0325

The interest is then calculated:

I=12,000\cdot 0.0325\cdot 8=3,120

Mrs. Adams will earn $3,120 of interest at the end of year 8.

Hence, each of the 5 children receive one fifteenth pie.
