Answer:

124.7 in²

Step-by-step explanation:

A hexagon consists of six equilateral triangles, each of side a, and we can divide each of them into two right triangles.

So, we can calculate the area of one right triangle and multiply by 12.

The formula for the area of one triangle is

A = ½bh

Step 1. Calculate the length of the side a

Per the Pythagorean Theorem,

[tex]\begin{array}{rcl}h^{2} + \left(\dfrac{a}{2}\right)^{2} & = & a^{2} \\\\6^{2} + \dfrac{a^{2}}{4} & = & a^{2}\\\\36 & = &\dfrac{3a^{2}}{4}\\\\144 & = & 3a^{2}\\\\\end{array}\\\\[/tex]

[tex]\begin{array}{rcl}a^{2} & = & \dfrac{144}{3}\\\\a & = & \dfrac{12}{\sqrt{3}}\\\\a & = & \dfrac{12\sqrt{3}}{3}\\\\a & = & 4\sqrt{3}\\\\\end{array}[/tex]

2.Calculate the area of a small triangle

The base of a small triangle is  

b = ½a = ½ × 4√3 = 2√3

The area of one small triangle is

A = ½ bh = ½× 2√3 × 6 = 6√3 in²

3. Calculate the area of the hexagon

A = 12 × 6√3 = 72√3 = 124.7 in²

To find the area of a regular hexagon, use the formula A = (1/2) x Perimeter x Apothem, find the side length with the apothem, calculate the perimeter, and then apply the values to the formula.

To find the area of a regular hexagon with an apothem of 6 inches, you can use the formula for the area of a regular polygon, which is A = (1/2) x Perimeter x Apothem. A regular hexagon can be split into six equilateral triangles, which means each side of the hexagon is equal in length. Since the apothem corresponds to the height of each of these triangle components, you can use the fact that in an equilateral triangle, the ratio of the side to the apothem is √3:1 to find the side length. Once the side length (s) is known, you can find the perimeter (P) of the hexagon by multiplying the side length by six. Then, plug the perimeter and the apothem into the formula to calculate the area.

Step 1: Calculate the side length (s).

Step 2: Calculate the Perimeter (P).

Step 3: Calculate the area (A).

Answer:

Lines a and b are parallel and lines c and d are parallel.

Step-by-step explanation:

Given in the question four lines a , b, c, d.

If two parallel lines (a,b) are cut by a transversal(d), then corresponding angles m<7 and m<15 are congruent.

They are know as corresponding angles.

Hence lines a and b are parallel.

If two parallel lines (c,d) are cut by a transversal(d), then corresponding angles m<13 and m<15 are congruent.

They are know as corresponding angles

Hence lines c and d are parallel

Answer:

The sequence of transformation is reflected across the y-axis and translated 2 units down

Step-by-step explanation:

Lets revise some transformation

- If point (x , y) reflected across the x-axis

∴ Its image is (x , -y)

- If point (x , y) reflected across the y-axis

∴ Its image is (-x , y)

- If point (x , y) translate h units to the right

∴ Its image is (x + h , y)

- If point (x , y) translate h units to the left

∴ Its image is (x - h , y)

- If point (x , y) translate k units up

∴ Its image is (x , y + k)

- If point (x , y) translate k units down

∴ Its image is (x , y - k)

* Now lets solve the problem

∵ The vertices of figure ABCD are:

  A (-1 , 3) , B (1 , 0) , C (2 , 3) , D (1 , 4)

∵ The vertices of figure A"B"C"D" are:

  A" (1 , 1) , B" (-1 , -2) , C" (-2 , 1) , D" (-1 , 2)

* Lets compare between ABCD and A"B"C"D"

∵ All x-coordinates has opposite signs

  -1 ⇒ 1 , 1 ⇒ -1 , 2 ⇒ -2 , 1 ⇒ -1

∴ The ABCD is reflected across the y-axis

∵ All y-coordinates subtracted by 2

 3 ⇒ 1 , 0 ⇒ -2 , 3 ⇒ 1 , 4 ⇒ 2

∴ The ABCD is translated 2 units down

* The sequence of transformation is reflected across the y-axis

  and translated 2 units down

Answer:

The answer is 15/52. (Please make me as brainliest (: )

The probability that he will get a blue pen, and he will not get a yellow highlighter is 15/52 option fourth is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have:

Eli has 8 black pens and 5 in his desk drawer. He also has 3 yellow highlighters, 4 green highlighters, and 5 pink highlighters in his pencil case.

Total pens = 8+5 = 13

The probability of choosing the blue pen = 5/13

Total highlighter = 3+4+5 = 12

The probability of choosing yellow highlighter = 3/12 = 1/4

The probability of not choosing yellow highlighter = 1 - (1/4) = 3/4

The probability that he will get a blue pen, and he will not get a yellow highlighter:

= (5/13)(3/4)

= 15/52

Thus, the probability that he will get a blue pen, and he will not get a yellow highlighter is 15/52 option fourth is correct.

Answer:

1) vertex = (-2,4)

2) Focus = (-0.5,4)

3) x= -3.5

   y= 4

4)  y=4

Step-by-step explanation:

General equation of parabola that is parallel to a-axis and vertex at (h,k) is given as

(y - k)^2 = 4p (x - h)

where

vertex of parabola is at (h,k)

focus of parabola is given at (h + p, k)

the directrix of parabola is given as x = h - p.

Now

1)

finding vertex of parabola:

Given equation of parabola

(y-4)^2=6(x+2)

Comparing with the general form, we get

h=-2 ,k=4 and 4p=6

hence vertex = (-2,4)

2)

Finding focus

Comparing with the above standard form we get

k=4, h=-2, p=3/2

Since the given parabola is parallel to x-axis and also p is positive hence it will opens to the right.

As focus is inside the parabola and it is p units to the right of the vertex:

hence

focus of parabola (h + p, k)=(-2+3/2 , 4)

                                            =(-0.5,4)

3)

Comparing with the above standard form we get

k=4, h=-2, p=3/2

Since the given parabola is parallel to x-axis and also p is positive hence it will opens to the right.

As directrix is outside the parabola and it is p units to the left of the vertex:

hence

directrix x=h-p

                = -2-3/2

                =-7/2

                = -3.5

             y= 4

4)

Finding Axis of symmetry:

as the vertex is (-2,4) also the given parabola is parallel to x-axis so

the axis of symmetry is a horizontal straight line passing through the vertex  at y=4 !

                      = | 2.6 -2.4|

                        ----------------- * 100%

                                  2.6

                      = .2 * 100%

In case you didn't know, corresponding angles are equal to each other and are on the same side of the traversal

Therefore the answer is angle CGH

Hope this helped!  

Answer:

Step-by-step explanation:

When two lines are crossed by another line, the angles in matching corners are called corresponding angles.

When the two lines are parallel Corresponding Angles are equal.

∠AFG and ∠CGH are corresponding angles.

The lines AB and CD are parallel, therefore m∠AFG = m∠CGH.

∠CGH and ∠DGH are supplementary angles.

Therefore m∠CGH + m∠DGH = 180°

Substitute m∠DGH = 54°:

m∠CGH + 54° = 180°          subtract 54° from both sides

m∠CGH = 126°

Therefore m∠AFG = 126°.

ANSWER

Brayden should have expanded the parenthesis first.

EXPLANATION

The expression Brayden is trying to simplify is

[tex]4n - {( n - 2)}^{2} [/tex]

To simplify this expression, the first thing to do is to expand the perfect square to obtain:

[tex]4n - {( n}^{2} - 4n + 4)[/tex]

We can now distribute the negative to the terms in the parenthesis.

[tex]4n - { n}^{2} + 4n - 4[/tex]

Answer:

He should have simplified [tex](n-3)^2[/tex] first then distribute the negative sign.

Step-by-step explanation:

Given that Brayden is simplifying the expression [tex]4n-(n-3)^2[/tex]. He begins by distributing the negative to the terms inside the parentheses. Which is basically the wrong step for the given problem.

Now we need to find about what should he have done instead.

According to order of operations, we should begin with exponent first.

So that means he should have simplified [tex](n-3)^2[/tex] first then distribute the negative sign.

Answer:

3/2x

Step-by-step explanation:

Find the slope of the original line.

3x + 2y = 19

2y = -3x + 19

y = -2/3x + 19

Use the reciprocal with the opposite sign.

3/2x

Final answer:

To find the slope of a line perpendicular to 3x+2y=19, first find the original line's slope (-1.5) and then calculate its negative reciprocal, which is 2/3.

Explanation:

The question asks about the slope of a line perpendicular to the given line 3x + 2y = 19. To find this, we first need to find the slope of the given line. We rearrange the equation into slope-intercept form, which is y = mx + b, where m is the slope. For 3x + 2y = 19, subtract 3x from both sides and divide by 2 to get y = -1.5x + 9.5. Thus, the slope of the given line is -1.5. The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. Therefore, the slope of the line perpendicular to the given line is 2/3.

If you have 1 nickle, how many quarters do you have? (3)

If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12

If you have n nickles, then you have 3n quarters so 3n = q, you have  a slightly different equation.

If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents

    5n + 10d + 25q = 460

This problem can be solved by setting up and solving a system of linear equations. After setting up the equations n+d+q=30, 5n+10d+25q=460, and d=q+2, you substitute and simplify to find that there are 10 nickels, 12 dimes, and 8 quarters.

Let's denote the number of nickels as n, dimes as d, and quarters as q. We have the following three equations based on the information given:

Solving these equations simultaneously will give you the numbers of each coin. If you substitute the third equation into the first and second equation, you get:

Simplify these equations to determine the values of n, q, and d. You would find that n=10, d=12, and q=8. So you have 10 nickels, 12 dimes, and 8 quarters.

The value of the first 7 is a thousand times as great as the value of the second 7 in 7,027.

Place value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value.

Given, a number 7,027 that has two 7 we need to compare the values of 7 in the form of place values.

thus,

Place value of first seven (right to left) = 1

Place value of 2 = 10

place value of 0 = 100

place value of second 7(right to left) = 1000

the first 7 or 7000, is 1000 times greater than the first 7. If the first seven is the one in the one's value and the second is in the 7, then it is 1000 times smaller.

The number of 4-letter passwords using the letters A-Z with repetition allowed is 456,976, while without repetition it's 358,800.

Explanation:

When calculating the number of 4-letter passwords that can be made using the letters A through Z, two scenarios are considered: one where repetition of letters is allowed, and one where it is not allowed.

Scenario a) Repetition of letters is allowed

For each position in the 4-letter password, there are 26 possibilities (since there are 26 letters in the alphabet). Because repetition is permitted, each of the four positions can be filled by any of the 26 letters. Thus, the total number of possible passwords can be found by multiplying the number of choices for each position: 26 x 26 x 26 x 26 = 456,976.

Scenario b) Repetition of letters is not allowed

When repetition of letters is not allowed, the number of choices decreases for each subsequent position in the password. The first position can be filled by any of the 26 letters, the second can be filled by 25 remaining letters (since one letter has been used), the third position by the 24 remaining letters, and the fourth by 23 remaining letters. Thus, the calculation would be: 26 x 25 x 24 x 23 = 358,800.

Apply formula

[tex]\sqrt[n]{x^p}\cdot\sqrt[n]{x^q}=\sqrt[n]{x^{p+q}}[/tex]

so we get:

[tex]\sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=\sqrt[3]{x^{1+2}}[/tex]

[tex]\sqrt[3]{x^1}\cdot\sqrt[3]{x^2}=\sqrt[3]{x^{3}}[/tex]

The original expression ∛x * ∛[tex]x^2[/tex] simplifies to x.

This means that the cube root of x times the cube root of [tex]x^2[/tex] is equal to x.

To simplify the expression ∛x * ∛[tex]x^2[/tex], we can apply the rules of exponents and radicals.

The cube root of x is equivalent to raising x to the power of 1/3.

Similarly, the cube root of [tex]x^2[/tex]  is equivalent to raising [tex]x^2[/tex] to the power of 1/3.

So, we have:

∛x = [tex]x^{(1/3)[/tex]

∛[tex]x^2 = (x^2)^{(1/3)} = x^{(2/3)[/tex]

Now, let's multiply these two expressions:

[tex]x^{(1/3)}\times x^{(2/3)[/tex]

To simplify, we add the exponents when multiplying like bases:

[tex]x^{(1/3 + 2/3)} = x^{(3/3)} = x^1[/tex]
