An octahedron and its net are shown below. All the faces are the same size and shape. What is the surface area of octahedron? Please answer !!

You're answer is Major Arc.

This value is approximate because pi = 22/7 is approximate.

===========================================================

Explanation:

Let's find the perimeter of the wheel, aka the circumference

C = pi*d

C = (22/7)*77

C = 242

The distance around the tire is approximately 242 cm

At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.

We can say the following

1 meter = 100 cm

242 meters = 24200 cm .... multiply both sides by 242

One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.

1 revolution = 242 cm

100 revolutions = 24200 cm ... multiply both sides by 100

---------------------------

We could also use a proportion to solve

(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)

1/242 = x/24200

1*24200 = 242x

242x = 24200

x = 24200/242

x = 100

22.1

Step-by-step explanation:

33.15/n

33.15/1.5

= 22.1

Answer:

6. (2,1) 7. (2,2)

Step-by-step explanation:

Number 6, Since it is a dilation of .5 you divide the x and y coordinate by 2 to get (2,1). X - 4/2=2, Y - 2/2=1

Number 7, Since it's rotating 90 degrees counterclockwise you switch the x and y coordinates. So from (x,y) to (y,x) and also when going counterclockwise you have to make the y coordinate becomes negative, so the counterclockwise equation is (-y,x) plug in your numbers and you get (2,2) as your 90 degree counterclockwise rotated coordinates.

Answer:

1051 or..

10.51

Step-by-step explanation:

Since 33=30 and 0.1081 is supposed to be as a percentage since its already a  decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number. Answer: 1051 or as a decimal 10.51

Answer:

[tex](x-1)^2+(y-6)^2=16[/tex]

Step-by-step explanation:

The equation of a circle is given by [tex](x-h)^2+(y-k)^2=r^2[/tex], where [tex](h,k)[/tex] is the center of the circle and [tex]r[/tex] is the radius of the circle.

From the diagram, we can find the following:

Thus, we have:

[tex](x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}[/tex]

Answer:

(x-1)^2 + (y-6)^2 = 16

Step-by-step explanation:

center = (1,6)

radius = 4

equation of a circle (x-h)^2+(y-k)^2=r^2

(x-1)^2 + (y-6)^2 = 16

a. 2x^-3 • 4x^2

To solve this using only positive exponents, follow these steps:

i. Rewrite the expression in a clearer form

2x⁻³ . 4x²

ii. The position of the term with negative exponent is changed from denominator to numerator or numerator to denominator depending on its initial position. If it is at the numerator, it is moved to the denominator. If otherwise it is at the denominator, it is moved to the numerator. When this is done, the negative exponent is changed to positive.

In our case, the first term has a negative exponent and it is at the numerator. We therefore move it to the denominator and change the negative exponent to  positive as follows;

[tex]\frac{1}{2x^3} . 4x^2[/tex]

iii. We then solve the result as follows;

[tex]\frac{1}{2x^3} . 4x^2[/tex] = [tex]\frac{2}{x}[/tex]

Therefore, 2x⁻³ . 4x² = [tex]\frac{2}{x}[/tex]

b. 2x^4 • 4x^-3

i. Rewrite as follows;

2x⁴ . 4x⁻³

ii. The second term has a negative exponent, therefore swap its position and change the negative exponent to a positive one.

[tex]2x^4 . \frac{1}{4x^3}[/tex]

iii. Now solve by cancelling out common terms in the numerator and denominator. So we have;

[tex]\frac{x}{2}[/tex]

Therefore, 2x⁴ . 4x⁻³ = [tex]\frac{x}{2}[/tex]

c. 2x^3y^-3 • 2x

i. Rewrite as follows;

2x³y⁻³ . 2x

ii. Change position of terms with negative exponents;

[tex]2x^3.\frac{1}{y^3} .2x[/tex]

iii. Now solve;

[tex]\frac{4x^4}{y^3}[/tex]

Therefore, 2x³y⁻³ . 2x = [tex]\frac{4x^4}{y^3}[/tex]

Answer:

Step-by-step explanation:

since for the bottom one. You found that 150 degrees for the obtuse angle and 30 degrees for the acute angle. So if you add those up you get 180. But there’s an opposite side so whatever is that side, you write for the other one I’m guessing

Answer:

B. 6^6

Step-by-step explanation:

the fraction can be flipped to get rid of the negative exponents. this leaves you with 6^8/6^6 which is equal to 6^2. if you multiply that by 6^4 you can add the exponent values together. So you get 6^6

Answer:

6^6 (Six to the power of six)

Step-by-step explanation:

Step one: Since you are using the power over a power rule, when it comes to dividing an exponent, it gets subtracted by the one below, so that results in 6^2

Step 2: Another power rule is that when you are multiplying exponents, you are actually adding exponents, so it would end up being 6^6

If you don't believe me, use a calculator called

Answer:

it was is face than surface I am 7th grade and doing the problem for class.

Step-by-step explanation:

If I am to late I am so sorry but for the next person that needs it.

(ﾉ◕ヮ◕)ﾉ*:･you can do it✧

For bases of solid figures, a lateral face is to a polygon what a lateral surface is to a circle.

The base of a solid figure is one of its faces that has been distinguished from the others in some way. The solid figure is usually oriented so that the base is situated at the bottom.

A pyramid is a three-dimensional figure with only one base. The base can be any polygon. The other faces are triangles. A pyramid is named according to the shape of its base.

Answer:

The volume is:

[tex]V_{2}=9984\: ft^{3}[/tex]

Step-by-step explanation:

The equation of the volume of a rectangular prism is:

[tex]V=L*W*H[/tex]

Where:

We know the volume is 768 ft³ and the new width change a 13 factor, in other words, W(2) = 13W(1), so we can divide each equation of the volume to find the new volume.

[tex]\frac{V_{1}}{V_{2}}=\frac{L*W*H}{L*W*13H}[/tex]

[tex]\frac{768}{V_{2}}=\frac{L*W*H}{L*W*13H}[/tex]

L and W remain constant.

Therefore, we just need to solve it for V(2).

[tex]\frac{768}{V_{2}}=\frac{1}{13}[/tex]

[tex]V_{2}=13*768=9984\: ft^{3}[/tex]
