area of a regular hexagon with an apothem of 15 cm

Answers

Answer 1

Answer:

area = 779.4 cm²

Step-by-step explanation:

divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.

tan 60° = 15/x

1.7321 = 15/x

x = 8.66 (this is one-half of the base of the triangle)

base = 17.32 cm

area of one triangle = 1/2(17.32)(15) = 129.9 cm²

129.9(6) = 779.4 cm²   (because 6 triangles make up the hexagon)

Answer:

29

Step-by-step explanation:

In a triangle, a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

Given this formula, we knoe c^2 is the product of 21^2 + 20^2.

This gives you 841. Now you just find the square root of 841 which is 29.

Which of the following is closest to the circumference, in inches, of a circle that has a diameter of 12 inches?

Answers

Answer:

37.68 inches

Step-by-step explanation:

The formula for the circumference of a circle is 2πr.

The radius is 6, and 6⋅2 = 12 (diameter).

3.14 = pi.

12 ⋅ 3.14 = 37.68

Whichever answer is closest to 37.68 is your answer!

-24a^10

Step-by-step explanation:

Given the equation −4a^5⋅6a^5

This can also be written as

−4a5⋅6a^5

= (-4*6)(a^5*a^5)

= -24(a^{5+5})

= -24a^10

i need help with the last two. I forgot the formula and wondering if you will help me find which one is and isnt a triangle

Answers

Answer:

3. D) 26, 7, 31

4. B) 6, 34, 27

Step-by-step explanation:

Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.

#3:

2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.

12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.

14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.

7 + 26 is 33, which is greater than 31. So D would form a triangle.

D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.

#4:

17 + 18 is 35, which is greater than 19. So A would form a triangle.

11 + 22 is 33, which is greater than 25. So C would also form a triangle.

5 + 18 is 23, which is greater than 20. So D would form a triangle.

6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.

B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.

Answers

Answer:

2/3

Step-by-step explanation:

All you do is find the reciprocal,

you take the equation, flip, then change the sign of the numerator. so,

In this it's already done, the sign on top is already changed and so is the equation fliped so we do the opposite,

which would give you 2/3 because the perpendicular line of 2/3 is -3/2 which makes them perpendicular to each other and there is your answer.

1/8 + 9/40 as a fraction in simplest form

Answers

Find the least common multiple of 8 and 40 which is 40. The denominator will be 40. For 8 to get to 40 we have to multiply the top number by five since 8 x 5 is 40.

So we will have:

5/40

9/40 already has 40 as its denominator so we will keep the fraction like that:


5/40 + 9/40 = 14/40


14/40 can be simplified by 2.


7/20




So the answer is 7/20.



Hope this helped, have an awesome day! <3

Answer:

7/20

Step-by-step explanation:

9/40, 9 divided by 40 is 0.225. 1/8, 1 divided by 8 is 0.125. Add 0.225 and 0.125 you get 0.35. 35% (0.35) of 100 to a fraction is 7/20. 7 divided by 2 is 3.5 or 0.35, 20 divided by 2 is 10 or 1. So yeah. Hope This Helps :)

What is the likelihood that a point chosen inside the square will also be inside the circle ?It Chose one : A. is impossible ,B. it is unlikely, C it is likely D. it is certain

Answers

Answer:

C. It is likely

Step-by-step explanation:

Given

See attachment for diagram

For the square.

Let

[tex]Length = L[/tex]

So, the area is:

[tex]Area = Length^2[/tex]

[tex]A_1=L^2[/tex]

The side length of the square equals the diameter of the circle.

So:

[tex]diameter (d) = L[/tex]

The radius is:

[tex]r = \frac{1}{2}d[/tex]

[tex]r = \frac{1}{2}L[/tex]

The area is:

[tex]Area = \pi r^2[/tex]

[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]

[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{28} L^2[/tex]

The likelihood that a point will be common to the square and the circle is:

[tex]Pr = \frac{A_2}{A_1}[/tex]

[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]

[tex]Pr = \frac{22}{28}[/tex]

[tex]Pr = 78.57\%[/tex]

The above probability is greater than 50% but less than 100%.

Hence, it is likely

Answer:

C. Likely

Step-by-step explanation:

all the points are in the circle so it's likely to choose a point inside the circle

Find the equation parallel to y = -x - 5 and passing through (-3, -3)

Answers

Answer:

y = -x - 6

Step-by-step explanation:

If it's parallel, then it means that the slope will remain the same. The slope is

-1.

To find the y-intercept, you need to plug the coordinates into the equation,

y = -1x + b

-3 = -1(-3) + b

-3 = 3 +b

-6 = b

The equation is y = -x - 6
