Step-by-step explanation:

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:

(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.

Answer:

Polynomial 1:

Simplified Form: 6x^2 - x - 1

Name by Number of Terms: trinomial

Polynomial 2:

Name by Degree: linear

Name by Number of Terms: binomial

Polynomial 3:

Simplified Form: 2

Name by Degree: constant

Step-by-step explanation:

Polynomial 1:

(x-1/2)(6x+2)

6x^2 - 3x + 2x - 1

6x^2 - x - 1

It has 3 terms, so it's a trinomial.

Polynomial 2:

There is one term with x and x is raised to the first degree, so it's linear.

There are 2 terms, so it's a binomial.

Polynomial 3:

4(5x^2-9x+7)+2(-10x^2+18x-13)

20x^2 - 36x + 28 -20x^2 + 36x - 26

28 - 26

2

Since there are no variables and the answer is just 2, it's a constant.

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 )

Answer:

699(0.90)(1.07)

Step-by-step explanation:

Given that:

Regular cost of couch = $699

Onsale percentage = 10%

Sales tax in purchase = 7%

Final price of couch :

New price at Selling percentage :

Regular price * (discount) * (sales tax percentage)

Regular price * (100% - 10%) * (100 + 7%)

699 * (1 - 0.1) * (1 + 0.07)

699 * 0.90 * 1.07

699(0.90)(1.07)

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:

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

Answer:

14.6+4x

Step-by-step explanation:

permimeter=length(2)+width(2)

7.3+x would be the length

so if you multiplied (7.3+x)2, you would get 14.6+2x if you distributive property.

Then if you multiply the width, x, by 2, you get 2x.

So we would get 14.6+2x+2x when we add them together.

And that would be 14.6+4x if you combine like terms.

And that would be your answer.

the graphing would be easier to use because it demonstrates the numbers that are in the situation

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:

[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.
