I need help with this question, please.

Given:

One side = 8x-10

Another side = 2(x+1)

To find:

The perimeter of the pentagon.

Solution:

We know that, all five sides of a regular pentagon are equal.

[tex]8x-10=2(x+1)[/tex]

[tex]8x-10=2x+2[/tex]

[tex]8x-2x=10+2[/tex]

[tex]6x=12[/tex]

Divide both sides by6.

[tex]x=2[/tex]

Now, the length of each side of the pentagon is

[tex]Side=8(2)-10[/tex]

[tex]Side=16-10[/tex]

[tex]Side=6[/tex]

We know that, perimeter of a regular pentagon is

[tex]P=5a[/tex]

Where, a is the side length.

[tex]P=5(6)[/tex]

[tex]P=30[/tex]

Therefore, the perimeter of the regular pentagon is 30 units.

The answer is x = 11/36

lt is 100% right

Where the above right triangle is given, note that the value of x when rounded to the nearest tenth is 19.2.

A right triangle is a triangle with one angle measuring 90°, forming a perpendicular side.

In this case,the base is 9 and the height is   17. Using   the Pythagorean theorem, we can calculate the length   of the hypotenuse as follows:

x² = 9² + 17²

x²= 81 + 289

x² = 370

To find the value of x, we take the square root of both sides  -

x = √370

x = 19.2353840617

x ≈ 19.2 (rounded to the nearest tenth)

The required translation as of the given condition is (6, 5).

Given that,
To apply the following rule to the point (-5,6): (x,y)-->(y, -x).

Coordinate, is represented as the values on the x-axis and y-axis of the graph

Translation of a point is defined as changing the location of the point on an arbitrary space with the help of any function and instructions.

Here,
In the question, a rule is mentioned for the transposition of the coordinates,
(x,y)-->(y,-x)
we just need to simply poor the coordinate in the given translation equation,

Answer:

Mr Sanders likely found that 1/3 of students have completed 12 or more paintings because there are 6 bars on the histogram, and 2 of the bars represent students with 12 or more completed paintings. The actual fraction of the students who have completed 12 or more paintings is 4/19.

Step-by-step explanation:

There are 19 students in Mr Sanders's class. There are 6 bars on that histogram. He most likely thought that since the 2/6 is equal to 1/3, 1/3 of his students completed 12 or more paintings. That is not the case. Two-sixths/one-third isn't even a whole number. The other options are 2/3, 4/19, and 4/17. Two-thirds and four-seventeenths are not whole numbers as well. So that leaves 4/19. Four-nineteenths is actually equal to the whole number 4. We must put 4/19 as our answer because there are no such things as partial students...

Answer:

60

Step-by-step explanation:

Angles 1 and 2 are supplementary, which means that their sum is 180 degrees.

180 - 120 = 60

Angle 1 is 60 degrees

If Z2 measures 120°. We can see that Angles 1 and Angles 2 are supplementary. Therefore, Angle 1 is 60 degrees.

Two angles whose sum is 180° are called supplementary angles.

If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.

Those two-two angles are two pairs of supplementary angles.

That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

If Z2 measures 120°

We can see that Angles 1 and Angles 2 are supplementary, which means that their sum is 180 degrees.

Angles 1 + Angles 2 = 180

Angles 1= 180 - 120

Angles 1 = 60

Therefore, Angle 1 is 60 degrees.

Answer

<F = 105°

<G = 41°

<J = 34°

GJ = 19m

JH =14m

GH = 16m

Step-by-step explanation:

Since triangle DEF is congruent to triangle GJH, the following are true

<D = <G

<E = <J

<F = <H

Given

<H = 105°

Hence <F = 105°

Also <E = 34° =<J

From ∆GHJ

<G+<H+<J = 180°

<G+105+34 = 180°

<G + 139 =180

<G= 180-139

<G = 41°

Get the sides. For the sides, the following are true

DE = GJ = 19m

Also EF =JH = 14m

DF =GH = 16m

Answer:

The equation of the line in standard form is y = -1/2·x - 3

Step-by-step explanation:

From the given graph, the "x" and "y" coordinates points through which the line of the graph passes are;

(-4, -1), (-2, -2), and (2, -4)

The slope, m, of the graph is given as follow;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, by substituting the values of the coordinates for two known points, we have;

[tex]Slope, \, m =\dfrac{(-4) -(-1)}{2-(-4)} = \dfrac{(-4) + 1}{2+4 } = \dfrac{-3}{6} = -\dfrac{1}{2}[/tex]

The slope of the graph, m = -1/2

The equation of the graph on point and slope form is given as follows;

y - (-4) = -1/2(x - 2)

y = -x/2 + 1 - 4 = -x/2 - 3

The equation of the line in standard form, y = m·x + c  is y = -1/2·x - 3.

Step-by-step explanation:

Given the expression

[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)[/tex]

Apply the exponent rule:

[tex]a^b\cdot \:a^c=a^{b+c}[/tex]

so the expression becomes

[tex]\left(3x^2\right)\:\left(5x^8\right)\:\left(6x^5\right)=3\cdot \:\:5\cdot \:\:6x^{2+8+5}[/tex]

Add the exponent numbers: 2+8+5=15

                             [tex]=3\cdot \:5\cdot \:6x^{15}[/tex]

Multiply the numbers: 3×5×6=90

                             [tex]=90x^{15}[/tex]

Therefore, we conclude that:

[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)=90x^{15}[/tex]

The correct graph for the given inequality is the 2nd one.

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Given that,

Max correctly solved the inequality and a ≤ -50.

The solution set is all real numbers less than or equal to -50.

Since -50 is inclusive, we draw a closed circle on -50 on the number line and draw the arrow to the left.

Hence, the correct graph is the 2nd one.

Step-by-step explanation:

Using the Pythagorean Theorem, it is found that he would travel 92 miles farther by  walking from his home to his friend's house and then from  his friend's house to work than he would travel by walking  from his home directly to work.

The Pythagorean Theorem states that, on a right triangle, the length of the hypotenuse squared is the sum of the length of each leg squared, that is:

[tex]h^2 = l_1^2 + l_2^2[/tex]

Walking from his home to his friend's house and then from  his friend's house to work, Jardon travels 240 + 120 = 360 yards.

Directly from his home to work, the distance is the hypotenuse of a right triangle with legs [tex]l_1 = 240, l_2 = 120[/tex], hence:

[tex]d^2 = 240^2 + 120^2[/tex]

[tex]d = \sqrt{240^2 + 120^2}[/tex]

[tex]d = 268[/tex]

360 - 268 = 92

He would travel 92 miles farther by  walking from his home to his friend's house and then from  his friend's house to work than he would travel by walking  from his home directly to work.
