For this case we have that the total of the balls is 86. We know there are 8 footballs then:

Basketball: Two more than twice the number of footballs are basketballs, that is:

2 + 2 (8) = 2 + 16 = 18

There are 18 Basketballs.

Baseballs: Four less than 5 times the number of footballs are baseballs, that is:

5 (8) -4 = 40-4 = 36

There are 36 Baseballs.

Softballs: Six more than half of baseballs are softballs. That is to say:

6+ \frac {36} {2} = 6 + 18 = 24

There are 24 Softballs

If we add we must get 86.

8 + 18 + 36 + 24 = 86

ANswer:

There are 8 Footballs

There are 18 Basketballs.

There are 36 Baseballs.

There are 24 Softballs

Help help needed for composition of function
dimulka [17.4K]

Answer:

\circledast \ \ f\circ f\left( x\right) = x

\circledast \ \ g\circ g\left( x\right)  =4x - 21

Step-by-step explanation:

f(x)=\frac{5}{2x}

g(x) = 2x - 7

==============

f\circ f\left( x\right)  =\frac{5}{2\left( f\left( x\right)  \right)  }

             =\frac{5}{2\left( \frac{5}{2x}  \right)  }

             =\frac{5}{\left( \frac{5}{x}  \right)  }

             =5\times\frac{x}{5}

             =x

_____________

g\circ g\left( x\right)  =2(g(x)) - 7

            = 2(2x - 7) - 7

           = 4x - 14 - 7

           = 4x - 23

What is the value of $750 invested into an account with an annual rate of 3.25% compounded continuously for 4 years and 3 months
Goshia [24]

Answer:

$861.09

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A = Pe^{rt}

<em>A = total </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal) </em>

<em>t = time (years) </em>

<em />

First, change 3.25% into its decimal form:

3.25% -> \frac{3.25}{100} -> 0.0325

Next for <em>t, </em>we can use 4.25 since 4 years and 3 months is 4.25 in its decimal form. Now lets plug in the values:

A=750e^{(0.0325)4.25}

A=861.09

Your answer is $861.09

Rufina [12.5K]

Answer:

Part A) The percentage increase was 6.1\%

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%

Part B) Compare the percentage increase with the inflation

6.1\%>5\%

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year
