If I read correctly, 2456 pennies needs to be divided simply by 3 then rounded to the nearest hundredth. So you would do 2456/3 3 goes into 24 how many times? Then 3 goes into 5 how many times, then continue the pattern. Once you've gotten a decimal to the thousandth, round the number to the hundredth and there you go

In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 1
Afina-wow [57]

Answer:

a) P(t) = 330 (1.11)^{t}

b)P(t) →population after t years.

   t →number of years.

c) Number of deer after five years = 556

Step-by-step explanation:

a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.

So, we can use the formula

                             P(t) = P (1+\frac{r}{100} )^{t}

                             P(t) = 330 (1+\frac{11}{100} )^{t}

                             P(t) = 330 (1.11)^{t}

b) In this model

                        P(t) → population after t years

                          P → present population

                          r → annual increasing rate

c) Number of population after 5 years is,

                    P(5) = 330 (1.11)^{5}

                           = 556

 Number of deer after 5 years = 556

You are asked to find the missing value in

... 40 + ? = 70

given that it is also the solution to

... ? + 5 = 35

Either way, you subtract the constant that is on the same side of the equation as the unknown.

... 40 + ? - 40 = 70 - 40

... ? = 30 . . . . the missing value

_____

You can check to see if this also satisfies the equation

... 30 + 5 = 35 . . . . . . . true

Solve for the variable: 12.9 = x + 7.1 5.8 -5.8 20 -20
olya-2409 [2.1K]
12.9 = x + 7.1
subtract 7.1 from both sides to isolate the variable, x.

5.8 = x

5.8 is your answer.
