There are 185 deer in a state park. The population is increasing at the rate of 16% per year. Enter a

stich3 [128]

Answer:

Approximately 3.4 years more or less

Step-by-step explanation:

If we represent this exponential growth as P=185(1.16)^n where n is the number of years passed and P is the population, then:

P=185(1.16)^n

305=185(1.16)^n

1.65=1.16^n

log₁.₁₆(1.65)=log₁.₁₆(1.16^n)

3.37=n

So the deer population will reach 305 in approximately 3.4 years.

Density = Mass/Volume

Given the following

Mass = 960g

Volume = 120cm^3

Substitute

Density = 960g/120cm^3

Density = 8g/cm³

16.5÷10 = 1.65 <br> Explain how you decided where to place the decimal

MariettaO [177]

Think about the question. In division, if you divide by 1, the number stays the same. If you divide by a larger number (like 10), the answer will get smaller. Therefore, you know to move the decimal to the left.

Here, there is one zero after the 1, so you move the decimal back one space. If it was divided by 100, the answer would be 0.165

Two brothers Steven and Walter each inherit 41000. Steven invests his inheritance in a savings account with an annual return of

umka2103 [35]

Answer:

Walter earns $1,517 more than Stevens in one year.

Step-by-step explanation:

Giving the following information:

Two brothers Steven and Walter each inherit $41,000

Steven:

Annual return= 2.7%

Walter:

Annual return= 6.4%

<u>To determine the future value for the brothers, we need to use the following formula:</u>

FV= PV*(1+i)^n

Steven:

FV= 41,000*1.027= $42,107

Walter:

FV= 41,000*1.064= $43,624

Difference= 43,624 - 42,107= $1,517

Walter earns $1,517 more than Stevens in one year.
