Answer:

Heptagon = 84 ft²

Octagon  = 186 yd²

Triangle = 48√3 m²

Step-by-step explanation:

[tex]\textsf{area of a regular polygon}=\dfrac12ap[/tex]

where:

Heptagon

a = 5.0 ft

p = 33.6 ft

⇒ area = 1/2 x 5.0 x 33.6 = 84 ft²

Octagon

a = 7.5 yd

p = 8 x 6.2 = 49.6 yd

⇒ area = 1/2 x 7.5 x 49.6 = 186 yd²

Triangle

Formula for the apothem of an equilateral triangle :

[tex]a=\dfrac{s}{2\sqrt{3}}[/tex]  where [tex]s[/tex] = side length

a = 4, so:

[tex]4=\dfrac{s}{2\sqrt{3}}[/tex]

[tex]\implies 8\sqrt{3}=s[/tex]

Now we know the side length, we can calculate the perimeter (p):

p = 3 x 8√3 = 24√3

⇒ area = 1/2 x 4 x 24√3 = 48√3 m²

Answer:

0

Step-by-step explanation:

Slope can be conceptualized as rise over run.

To get rise, you can see the difference between the two 'y' coordinates. In this case, it's 0 (-5 and -5). At this point, since the numerator of our [tex]\frac{rise}{run}[/tex] fraction is 0, you know it's just gonna be 0 no matter the value of the run.

Answer:

3x + 6y

Step-by-step explanation:

so the perimeter is 12x + 8y and a side is 4x-2y so that means that side and the side across is 8x-4y so you put it all to one side to get 6x +12y then divide that by 2 to find 1 side so the side is 3x + 6y

Answer:

x = -3

y = 7

Step-by-step explanation:

4y + 2 = 30

x - 4y = -31

Simplify the first equation by subtracting 2 from both sides:

4y = 28

Divide both sides by 4

y=7

Plug 7 in for y to solve for x:

x - 4(7) = -31

x - 28 = -31

Add 28 to both sides

x=-3

(x,y)=(-3,7)

Answer:

81.6 inches squared

Step-by-step explanation:

The formula for calculating all parallelograms is Area+=base*height.

The height is given to you, 6.8, the base of the figure is also given, 12.

Now all you have to do is to multiply.

That would get you to 81.6.

(When asked for area of parallelogram, the length of any line other than the height and base is not needed)

Answer:

x = 3

Step-by-step explanation:

x^5 = 243

Take the fifth root of each side which is the same as raising each side to th 1/5 power. Also, 243 = 3^5.

x^5 = 3^5

(x^5)^(1/5) = (3^5)^(1/5)

x = 3

Answer:

3

Step-by-step explanation:

x^5= 243

I guess we're looking for x

so what we do is just find the fifth root of 243

and that's 3

Answer: Your answer is 55% = 11 / 20

Hope this helps!

Answer:

11/20

Step-by-step explanation:

Step 1: We represent the given number as a fraction by dividing it by 100.

Hence, we write it as 55/100.

Step 2: Simplify the fraction by using common factors of numerator and denominator.

Now, 55% can be written as 55 / 100.

On simplifying the above fraction:

55 / 100 = 11 / 20 [Dividing numerator and denominator by their greatest common factor, that is 5.]

Therefore, 55% can be represented as 11/20 in fractional form.

Answer:

35 degrees

Step-by-step explanation:

Assuming B is the center of the circle, the measure of arc AC is 70 degrees since the measure of a central angle is equal to the measure of the arc it intercepts.

This means that by the inscribed angle theorem, which states that the measure of an inscribed angle is half the measure of the arc it intercepts, the measure of the desired angle is 35 degrees.

Answer:

2537

Step-by-step explanation:

3/5 of 4,283.30 = 2569.98

2569.98 - 19.99 = 2549.99

2549.99 - 12.99 = 2537

Answer:
