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 with step-by-step explanation:

We are given the following two functions:

[tex]s(x) = 3x - 6[/tex]

[tex]t(x) = 6 - 3x[/tex]

We are to find the simplified formula and domain for [tex] v ( x ) = \frac { s ( x ) } { t ( x ) } [/tex] and [tex] w ( x ) = \frac { t ( x ) } { s ( x ) } [/tex].

[tex]\frac{3x-6}{6-3x}=\frac{3(x-2)}{3(2-x)}=\frac{x-2}{2-x}=\frac{x-2}{-(x-2))}=-1 [/tex]

So the domain for this function is (-∞, +∞) for v(x) = -1.

[tex]\frac{6-3x}{3x-6}=\frac{3(2-x)}{3(x-2)}=\frac{2-x}{x-2}=\frac{2-x}{-(-x+2)}=\frac{2-x}{-(2-x)}=-1[/tex]

The domain of this function is (-∞, +∞) for w(x)= -1

ANSWER

v(x)=-1

Domain: (-∞,2)U(2,+∞)

EXPLANATION

We have the given function

s(x) = 3x - 6 and t(x) = 6 - 3x.

We want to find the simplified formula and domain for

[tex]v(x) =( \frac{s}{t} )(x)[/tex]

[tex]v(x) = \frac{s(x)}{t(x)} [/tex]

[tex]v(x) = \frac{3x - 6}{6 - 3x} [/tex]

This function is defined if and only if

[tex]6 - 3x \ne0[/tex]

[tex]x \ne2[/tex]

Hence the domain is:

[tex]x \ne2[/tex]

We now simplify to obtain;

[tex]v(x) = \frac{ - (6 - 3x )}{6 - 3x} = - 1[/tex]

we can think of this as the same as a deposit in a bank, so let's use the compound interest formula, since the book is increasing in value 12% per annum.

[tex]\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$0.35\\ r=rate\to 12\%\to \frac{12}{100}\dotfill &0.12\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{per annum, thus once} \end{array}\dotfill &1\\ t=years\dotfill &t \end{cases} \\\\\\ A=0.35\left(1+\frac{0.12}{1}\right)^{1\cdot 5}\implies A=0.35(1.12)^t[/tex]

$36

128/7 is about 18

18x2= 36

Answer:

36.57

Step-by-step explanation:

To convert 3.2 feet to inches, multiply by the conversion factor of 12 inches per foot. The calculation 3.2 feet x 12 inches/1 foot results in 38.4 inches.

To convert 3.2 feet to inches, we use the following ratio: 1 foot = 12 inches. This is a standard conversion factor between feet and inches in the customary system of measurements.

First, set up the conversion like this:

Multiply the number of feet by the unit equivalence.

3.2 feet x 12 inches/1 foot = x inches.

Perform the multiplication to solve for x.

3.2 x 12 = 38.4 inches.

Therefore, 3.2 feet is equivalent to 38.4 inches. Remember, when converting from a larger unit to a smaller unit like feet to inches, you need to multiply by the conversion factor.

Answer:

135????

Step-by-step explanation:

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:

The answer would be B, 2x2+7x-15.

Step-by-step explanation:

Use the distributive property!!

(2x-3)(x+5)

distribute the  2x to the x and 5.

You get 2x2+10x

distribute the -3 to the x and 5.

You get -3x-15

combine like terms:

2x2+10x-3x-15

You get the answer 2x2+7x-15

Multiply the side length by the number of sides to get the perimeter. The formula for finding the perimeter of a regular polygon is just the number of sides x the length of any side. Once you've multiplied those 2 numbers together, you've found the perimeter of the polygon

Final answer:

The perimeter of a polygon is calculated by adding together the lengths of all its sides. For regular polygons with equal side lengths, the perimeter is the side length multiplied by the number of sides. For irregular polygons, all unique side lengths must be measured and summed.

Explanation:

The perimeter of a polygon is the total length around the shape. It is calculated by summing the lengths of all its sides. For a regular polygon with all sides of equal length, like a square, if one side length is a, then the perimeter is simply 4a because there are four sides. In the case of irregular polygons, each individual side length must be measured and added together to find the total perimeter.

For instance, consider a rectangle with a length of l and a width of w; the perimeter would be 2l + 2w, because each opposite pair of sides are equal. The units used for the lengths will be the same units used for the perimeter, such as meters. Nonetheless, the calculation can become more complex with polygons of more sides. Each side must be accounted for precisely, and units must remain consistent.

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

[tex]n=\frac{5}{6} [/tex]

EXPLANATION

The given equation is

[tex] \frac{4}{5}n =\frac{2}{3} [/tex]

We multiply both sides of the equation by:

[tex]\frac{5}{4}[/tex]

[tex] \frac{5}{4}\times \frac{4}{5}n =\frac{2}{3}\times\frac{5}{4} [/tex]

Multiply and cancel out common factors

This implies that:

[tex]n=\frac{5}{6}[/tex]

Answer: Last option

{x| x>-3}

Step-by-step explanation:

We have the following inequality 3 (x + 2)> x

To solve the inequality, apply the following steps:

1) Apply distributive property

[tex]3 * x + 3 * 2> x\\\\3x + 6> x[/tex]

2) Subtract 6 on both sides of the inequality

[tex]3x +6 -6> x-6\\\\3x> x-6[/tex]

3) Subtract x on both sides of the inequality

[tex]3x-x> x-x-6\\\\2x> -6[/tex]

3) Divide by 2 both sides of the inequality

[tex]x> -3[/tex]

The solution is all numbers greater than -3

ANSWER

{x|x>- 3}

EXPLANATION

The given inequality is;

[tex]3(x+2) \: > \: x[/tex]

Expand the parenthesis to obtain,

[tex]3x+6>x[/tex]

Group like terms

[tex]3x-x \: > \: -6[/tex]

[tex]2x>-6[/tex]

Divide both sides by 2

[tex]x \: > \: - 3[/tex]

The correct choice is D.

Answer:

23  D

24  B

25  Add 6.1 to each side

Step-by-step explanation:

23.  w+2 < -1

Subtract 2 from each side

w+2-2 <-1-2

w < -3

There is an open circle at -3 with a line going to the left

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:

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:

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:

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

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

Hello there!

Answer:

Triangle 2

Step-by-step explanation:

To determine which triangle has the bigger area, we would need to figure our the area of the triangles.

To solve for the area of the triangles, we would use the formula length × width × height or l × w × h

They gave us the information to the triangles in the question, so we would just solve.

Triangle 1: [tex]300 *400*500= 60,000,000[/tex]

Triangle 2: [tex]300*400*700=84,000,000[/tex]

When you finish solving, you would see that triangle 2 has the bigger area.

Triangle 2 would be the CORRECT answer because it has a bigger area than Triangle 1.

Triangle 2. Area is length x width x height

Answer:

option A) yes, measure of interior angle is 90

Step-by-step explanation:

Tessellation:

the tiling of an flat surface or plane by one or more geometric surfaces is tessellation. No overlapping or gap or un-evenness is left during tessellation, all the shapes fit perfect to the plane or flat surface. There are three geometric shapes that can be used for tessellation.

These shapes are:

Square

Triangle

Hexagon

As in given problem the polygon given is square

So YES the tessellation of plan is possible and the as the interior angle of square is 90 degrees so

option A is correct complete answer i.e. yes, measure of interior angle is 90 !

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°.
