find the area of the regular polygon​

Answer:

Step-by-step explanation:

Given the expression (x+11)(2x+3)

We want to expand it and write equivalent expression

Generally if we want to expand an expression we will take one of the expression in one bracket and multiply with the other bracket and then take the other expression and multiply it with the other

E.g, (a+b) × (c + d)

Then, we take a × (c+d) and also b × (c+d)

We can do it the other way round too and it will give the same results.

So, applying this to the given expression

(x+11)(2x+3)

x(2x+3) + 11(2x+3)

2x² + 3x + 22x + 33

2x² + 25x + 33

Then, the equivalent expression is 2x² + 25x + 33

(x + 11)(2x + 3) = 2x² + 25x + 33

Answer:

Step-by-step explanation:

The area of the pyramid's base is 36 square inches.

The pyramid has 4 lateral faces.

The surface area of each lateral face is 18 square inches.

The area of the pyramid’s base is 36 in² and the surface area of each lateral face is 108 in². Then the total surface area is 144 in².

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The area of the pyramid’s base will be

Base area = 6 × 6

Base area = 36 in²

The area of the pyramid’s base is 36 in².

The pyramid has lateral faces that will be

Lateral face = 0.5 × 6 × 9

Lateral face = 27 in²

Then the surface area of each lateral face will be

Surface area = 4 × 27

Surface area = 108 in²

The surface area of each lateral face is 108 in²

Then the total surface area is 144 in².

No it is not necessary that Kelvin will get one head and one tail every time

Explanation:

Probability in math is equal to favorable outcomes/total outcomes

The coin has two sides a head and a tail. When we flip a coin we have 50-50 possibility of getting a head and a tail. It means with every toss we have 1/2 possibility of getting head as well as tail.

But this does not mean that when we toss a coin twice we will get one head at one toss and one tail at another toss.

There is a possibility of getting both heads as well as both the tails.

Answer:

Step-by-step explanation:

Triangles are similar if they have the same shape, but not necessarily the same size.

in this case we have

JK/MO = KL/ON = JL/MN

A) Use properties of similar triangles.

The measurement of angle J can be derived from triangle MNO.

Corresponding angle are congruent.

Angle J in triangle JKL correspond with angle M in triangle MNO.

Therefore:

Tangent M = opp/adj

tanM = 2/1.5

tanM = 1.3

M = tan-¹ 1.3

M = 52.43

J = M = 52.43°

B) MO in △MNO corresponds to JK in △JKL

C) JK/MO = KL/ON = JL/MN

find JL using Pythagoras theorem

JL² = KL² + JK²

JL² = 4²+3²

JL = √(16+8)

JL = 5

JK/MO = KL/ON = JL/MN

= 3/1.5 = 4/2 = 5/2.5 = 2/1

Therefore the ratio of larger triangle to small triangle is 2:1

Given:

Height of a cone = 50 m

Volume of cone = 5400π

To find:

The radius of the cone

Solution:

Volume of cone:

[tex]$V=\frac{1}{3}\pi r^2h[/tex]

[tex]$\frac{1}{3}\pi r^2h=5400\pi[/tex]

Cancel common factor π on both sides.

[tex]$\frac{1}{3} r^2h=5400[/tex]

Substitute h = 50.

[tex]$\frac{1}{3}\times r^2\times 50=5400[/tex]

Multiply by 3 on both sides.

[tex]$3 \times \frac{1}{3}\times r^2\times 50=5400\times 3[/tex]

[tex]$ r^2\times 50=16200[/tex]

Divide by 50 on both sides, we get

[tex]r^2=324[/tex]

Taking square root on both sides, we get

[tex]r=18[/tex]

The radius of the cone is 18 m.

Answer:

What grade of math is this?

Step-by-step explanation:

Answer:

31a/624 +7/26 = b

Step-by-step explanation:

a/8 - 7(3) = 4a - 78(b)

Multiply

a/8 - 21 =4a -78b

Multiply each side by 8 to get rid of the fractions

8(a/8 - 21) =8(4a -78b)

a - 168 = 32a -624b

Subtract 32a from each side

a -32a -168 = 32a -32a -624b

-31a -168 = -624b

Divide each side by -624

(-31a -168)/-624 = -624b/-624

(31a+168)/624 = b

31a/624 +7/26 = b

Answer:

b = (31a + 168)/624

Step-by-step explanation:

a/8 - 7(3) = 4a - 78(b)

78b = 4a - a/8 + 21

78b = (32-1)a/8 + 21

78b = (31a + 21(8))/8

78b = (31a + 168)/8

b = (31a + 168)/8 × 1/78

b = (31a + 168)/624

Final answer:

The plot will likely focus on Skylar's crucial mission in outer space, portraying her as an archetypal heroine, with the story revealing the destabilizing condition that led her to this moment.

Explanation:

Based on the excerpt, it's most likely that the plot will involve Skylar embarking on a crucial mission that affects life on Earth, suggesting that the narrative will focus on her as an archetypal heroine. Given that she's just awakened from a three-year journey in deep space, we can infer a narrative structure that will emphasize her actions and decisions in outer space rather than detailing her entire life history or returning home immediately. The story seems poised to dive into the destabilizing condition that brought Skylar into space, likely escalating towards a central conflict related to her mission, while building empathy for her character as she navigates challenges in a foreign environment.

Answer:

Let t = the tens digit and u = the units digit.

t + u = 8

10u + t = 10t + u + 54

10(8 - t) + t = 10t + 8 - t + 54

80 - 10t + t = 9t + 62

80 - 9t = 9t + 62

18t = 18

t = 1, u = 7

The number is 17.

Answer:

(-5,0) or (0,-25) is another solution

Step-by-step explanation:

Do you have a list of choices? If not, you could choose random choices for x and y to determine if they are solutions. Start by letting y = 0. We see that x = -5, so (-5, 0) is a solution to this equation. In fact, it represents the x-intercept of this line. Now, let x = 0. We now see that y = -25, so (0, -25) is another solution to the equation of this line. This coordinate pair is the y-intercept of the line. Try using other values of x and y to see if you can come up with other solutions to this equation. 

Answer:

(-5,0)

Step-by-step explanation:

Answer: 49600

Step-by-step explanation: There are 40 ways to choose the first number

and there are 40 ways to choose the second number.

Now we take some examples to determine how many choices there are for

the third number

If the second number is 23, then the 3rd number cannot be any of these

9 numbers 19,20,21,22,23,24,25,26,or 27, since they are not at least 5

numbers away from 23.  Same for all other 40 second numbers.

Let's look at a second example which includes some on both sides of 0.

If second number is 2, we couldn't choose any of the 9 numbers 38,39,0,1,2,3,4,5,6.

So thats 40-9 or 31 choices for the 3rd number.

Answer 40*40*31 = 49600 ways.

The horizontal distance between Zack and the water fountain is approximately 141.1 feet.

To find the horizontal distance between Zack and the water fountain, we can use trigonometry.

The tangent function relates the angle of depression (\(\theta\)) to the opposite side (height of the tower, \(h\)), and the adjacent side (horizontal distance, \(d\)):

[tex]\[ \tan(\theta) = \frac{h}{d} \][/tex]

Given:

Height of the tower = 75 feet

Angle of depression  = 28°

We rearrange the formula to solve for \(d\):

[tex]\[ d = \frac{h}{\tan(\theta)} \]\[ d = \frac{75}{\tan(28°)} \]Calculating \(\tan(28°)\), and then the distance \(d\):\[ \tan(28°) = 0.531 \]\[ d = \frac{75}{0.531} \]\[ d = 141.1 \][/tex]

So, the horizontal distance between Zack and the water fountain is approximately 141.1 feet.

5: 1 won, 2 tied

6: 2 won, 1 lost

7: 2 won, 1 tied

9: 3 won

The answer is 8 points.

Since there are 4 teams in a soccer tournament, and each team plays each of the other teams exactly once, and in each match, the winner receives 3 points and the loser receives 0 points, while in the case of a tie, both teams receive 1 point, to determine, after all the matches have been played, which total number of points is it impossible for any team to have received, the following mathematical logical reasoning must be performed:
