20.00 for each pair of shoes

Cost of one pair of shoes is $4.0625 (Approx.)

Cost of 25 pair gloves and 15 pair shoes = $374.25

Cost of 14 pair gloves and 4 pair shoes = $117.49

Cost of one pair of shoes

Assume;

Cost of one pair of gloves = a

Cost of one pair of shoes = b

So,

25a + 15b = 374.25 ......... eq1

14a + 4b = 117.49 ......... eq2

eq2 × 3.75

52.5b + 15b = 440.5875 ........ eq3

Eq3 - eq1

a = 2.41

So,

14a + 4b = 117.49

b = $4.0625

Cost of one pair of shoes = $4.0625 (Approx.)

Answer:

Final answer is [tex](4x^2+3)(x+2)[/tex].

Step-by-step explanation:

Given expression is [tex]4x^3+8x^2+3x+6[/tex].

Now we need to factor that by the method of grouping.

So make two groups having first two terms and then last two term.

Factor each group then factor once more.

[tex]=4x^2(x+2)+3(x+2)[/tex]

[tex]=(4x^2+3)(x+2)[/tex]

It can't be factored anymore so the final answer is [tex](4x^2+3)(x+2)[/tex].

the factored form of 4x^3+8x^2+3x+6 using the grouping method is (x+2)(4x^2+3).

To factor the polynomial 4x^3+8x^2+3x+6 using the grouping method, we can start by grouping terms in pairs and factoring out common factors in each pair. Here is a step-by-step explanation:

Therefore, the factored form of 4x^3+8x^2+3x+6 using the grouping method is (x+2)(4x^2+3).

Answer: 12 feet.

Step-by-step explanation:

The formula used to calculated the area of a rectangle is:

[tex]A=l*w[/tex]

Where "l" is the lenght and "w" is the width.

You need to find the lenght of the bedroom, then you must solve for the lenght "l":

[tex]l=\frac{A}{w}[/tex]

You know that the floor of Paul's and Matthew's rectangular bedroom has an area of 132 square feet and its width is 11 feet. Then, you can substitute these values into [tex]l=\frac{A}{w}[/tex] to calculated the lenght. Therefore, the result is:

[tex]l=\frac{132ft^2}{11ft}[/tex]

[tex]l=12ft[/tex]

Answer:

x = 8

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{\sqrt{2} }{2}[/tex], then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{2} }{x}[/tex]

Multiply both sides by x

x × sin45° = 4[tex]\sqrt{2}[/tex] ( divide both sides by sin45° )

x = [tex]\frac{4\sqrt{2} }{\frac{\sqrt{2} }{2} }[/tex]

   = 4[tex]\sqrt{2}[/tex] × [tex]\frac{2}{\sqrt{2} }[/tex] = 4 × 2 = 8

Answer: C 18000

Step-by-step explanation:

Julie contributes $12,000 to her 401k and her employer matches 50% of this amount, contributing an additional $6,000. Thus, the total balance in Julie's 401k after the employer's contribution is added is $18,000.

The question involves calculating the total balance in Julie's 401k account after her employer's contribution. Julie contributes $12,000 to her 401k, and her employer offers a 50% match on contributions. To find the total balance, first calculate the employer's contribution, which is 50% of Julie's contribution, so $12,000 x 0.5 = $6,000.

Adding the employer's contribution to Julie's contribution gives us the total balance in the 401k account. Therefore, $12,000 (Julie's contribution) + $6,000 (employer's match) = $18,000.

Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.

Answer:

80°

Step-by-step explanation:

The opposite angles of an inscribed quadrilateral add up to 180.

(2x + 13) + (3x + 37) = 180

(2x + 3y) + (5y) = 180

Solving the first equation:

5x + 50 = 180

5x = 130

x = 26

Solving the second equation:

2x + 8y = 180

2(26) + 8y = 180

52 + 8y = 180

8y = 128

y = 16

5y = 80.  So ∠D = 80°.

Hope this Helps! :)

Answer:

Portfolio: dividends, capital gains, interest

Passive: rent, multilevel marketing income, intellectual property sales

Step-by-step explanation:

Portfolio income is the income received through dividends, interest, or capital gains:

Dividends are distributed profits that a company pays to its shareholders.

Interest is the income generated by investing money in savings accounts or bonds.

Capital gains are profits earned by selling assets, such as stock or real estate. You earn capital gains after selling assets for higher prices than you paid to acquire them.

Here are the different types of passive income:

Rental income is income earned via renting apartments, houses, office buildings, or other properties owned.

Business income refers to income earned from a limited ownership stake in a business.

Creating or selling intellectual property involves income earned from an invention, sales of a book you wrote, profits from a movie, and so on.

Multilevel marketing income is income earned by increasing the company’s sales as well as recruiting other salespeople.

Answer:

5/10 or 1/2 because there is 10 marbles in total so denominator is 10 and we are pulling white marbles and there is 5 (so what ever the variable is for this case it is the white marbles that would be the numerator so 5/10)

Hope this Helps :D

Answer: white marble: you have a 5/10% chance

               Black marble: you have a 5/9% chance

Step-by-step explanation:

for the white marble you have 5 out 10 because there are half and half then you have to add them all up for the total and not placing it back in the bag there are only 9 left with still 5 black ones so you have a 5 out 9 chance to get a black one

Answer:

118°

Step-by-step explanation:

The sum of a triangle is always gonna be 180°. Adding 42° and 20° you get 62°. When you subtract 180° minus 62° you the third angle which is 118°.

the answer is 118

every triangle equals 180 so just subtract 180 and the two angles and boom 118 degrees

Answer:

D

Step-by-step explanation:

Answer D is correct.  The indicated line segments are both radii of the circle and are thus of the same length (and thus, congruent).

Answer: D. RE

Step-by-step explanation:

In the given picture , we have a circle with center R having two chords as WF and MU.

The two chords WF and MU have equal length.

i.e. [tex]WF=MU=11.2[/tex]

We know that the equal chords of a circle are equidistant from the center.

⇒ [tex]\overline{RA}=\overline{RE}[/tex]

Therefore, we conclude that RA is congruent to RE.

Answer:

Step 3 is wrong.

Step-by-step explanation:

They must subtract the 28 from 15 first. This will give you 3x=-13. Then, you divide each side by 3, giving an answer of x=-4.33, or x=-13/3.

Answer:

step 3 is wrong

Step-by-step explanation:

consider step 2

3x + 28 = 15 ( subtract 28 from both sides ) gives

3x = 15 - 28

3x = - 13 ← what step 3 should be

Choice D

24.  -15 > q-5

Add 5 to each side

-15+5> q-5+5

-10>q

q must be less than -10

B {-11,-12,-14}  are the only numbers all less than -10

25 p-6.1=10

Add 6.1 to each side

p-6.1+6.1 = 10+6.1

p =16.1

Answer:

24) C: {-9, -8, -7}

25) Add 6.1 to both sides of the equation.

Step-by-step explanation:

Question 24 is asking which set of numbers when subtracted by five is still greater than -15. C is the only one that matches.

(Edit: I realize after reading another answer that B is correct, not C. I misread the question.)

In question 25 you can easily solve for p by adding 6.1 to both sides of the equation.

Answer:

7

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [4, 6 ]

f(b) = f(6) = 6² - 3(6) - 10 = 36 - 18 - 10 = 8

f(a) = f(4) = 4² - 3(4) - 10 = 16 - 12 - 10 = - 6

Hence

average rate of change = [tex]\frac{8-(-6)}{6-4}[/tex] = [tex]\frac{14}{2}[/tex] = 7
