Answer:

21.5

Step-by-step explanation:

Hey there !!!!

to find the radius just divide by 2 because radius is the half of diameter:

43 / 2 = 21.5

( for correct divison add 21.5 + 21.5 = 43 )

hope it helped !!!

Answer: 320 miles

Step-by-step explanation:

Let the miles that they drove be represented by x.

Since Sarah drove two-fifths of the miles which is 128 miles, then the total miles would be:

= 2/5 × x = 128

0.4 × x = 128

0.4x = 128

x = 128/0.4

x = 320

The total miles is 320 miles.

Answer:

$29.14

$86.68

Step-by-step explanation:

$30 before tax

Discount: 20%

100% - 20% = 80% = 0.8

0.8 * $30 = $24 after discount

Tax: 6.4%

100% + 6.4% = 106.4% = 1.064

1.604 * $24 = 25.54 after tax and discount

Tip: 15% = 0.15

0.15 * $24 = $3.60

Total = $25.54 + $3.60 = $29.14

$75 before tax

10% discount

100% - 10% = 90%

90% of $75 = 0.9 * $75 = $67.50 after discount

Tax: 7%

100% + 7% = 107% = 1.07

1.07 * $67.5 = $72.23 after discount and tax

Tip: 20% = 0.2

0.2 * $67.50 = $13.50

Total = $72.23 + $13.50 = $85.73

Answer:

Step-by-step explanation:

just do x2.5

Answer:

here is a simple version

lets make A equal the exponent so (A=^2 or 3 or whatever)

the exponent will be the amount of times you want to repeat the process.

Now lets make x = the first array, so x=3

and lets make y = the second array, y=7

now a simple equation would be (3x)(7y)^A or for this you could say

(3x)(7y)^6

Answer:

22.75 hours per week

Step-by-step explanation:

We can see from the question that the target amount of money is $190.00 per week.

If Lauren Rodriguez earns $8.35 in one hour

then $190.00 will be earned in x hours

8.35x = 190.00

x = 190.00/8.35

x = 22.75 hours per week

Answer:

Part 1)

[tex]f(g(x))=10x^3+16[/tex]

Part 2)

The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=2x^2+16[/tex]

Which represents the amount of money Raul earns per ticket and:

[tex]g(x)=\sqrt{5x^3}[/tex]

Which represents the number of tickets Raul sells per hour.

Part 1)

We want to find f(g(x)).

So, we substitute g(x) for f(x). This yields:

[tex]f(g(x))=2(\sqrt{5x^3})^2+16[/tex]

This can be expanded a simplified as such:

[tex]f(g(x))=2((\sqrt{5})^2(\sqrt{x^3})^2)+16=10x^3+16[/tex]

Part 2)

Recall that f(x) outputs the amount of money Raul earns per ticket.

And g(x) inputs the amount of hours Raul works.

When we composed f(g(x)), the input and output stayed the same.

So, f(g(x)) represents the amount of money Raul earns per ticket (output of f(x)) given the amount of hours Raul works (input of g(x)).

Answer:

The composition f(g(x)) represents the amount of money Raul earns per ticket given the amount of hours Raul works

Step-by-step explanation:

Answer:

[tex]a21 = - 15 + 5(21 - 1) \\ = - 15 + 105 - 5 \\ = 85[/tex]

85 the 21st term of the sequence.

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

here, we have,

an = -15 + 5(n – 1)

so,

a_21= -15+(21-1)5

      =-15+100

      =85

Hence, 85 the 21st term of the sequence.

Answer:

(5,4)

Step-by-step explanation:

multiply each equation by the value that makes the coefficients of x opposite

(-1) · (4x + 6y) = (-1) · 44

4x + 2y = 28

simplify

-4x - 6y = -44

4x + 2y = 28

add the two equations together to eliminate x from the system

      -4x - 6y = -44

+      4x + 2y = 28

              -4y = -16

divide each term by -4

y = 4

substitute the value for y into one of the original equations, then solve for x

-4x - 6y = -44

-4x - 6(4) = -44

-4x - 24 = -44

     + 24   + 24

-4x = -20

divide by -4

x = 5

so, since x = 5 and y = 4 ....

the solution to the independent system of equations can be represented as a point.

The mean of the population is

.

The mean of the sample is

3.25

.

The difference between  the mean of the sample and the mean of the population is

0.75

.

Step-by-step explanation:

Just did it

The difference between the mean of the sample and the mean of the population is equal to 0.75

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

We are given the

2 5 10 N 4 1 5 3

The mean of the population is;

0 + 1 + 4 + 3 / 4 =  4.

The mean of the sample is;

4 + 1 + 5 + 3 / 4 =  3.25

The difference between the mean of the sample and the mean of the population is;

4 - 0.35 =  0.75
