Can someone please help me find the sum of each interior angle measure of the polygon, and can you please explain. I need help on both of these questions.

Answers

Answer:

I'm sorry I have no clue what this is. What grade are you in? I'm in seventh and I have never learned anything like this lol.

Step-by-step explanation:

3)first you count the sides
There are 8 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(8-2)*180
=6*180=1080

To find the measure of one interior angles divide the answer by the number of sides
900/8=112.5

4)first you count the sides
There are 7 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(7-2)*180
=5*180=900

To find the measure of one interior angles divide the answer by the number of sides
900/7= 128.57

2. then we find a place where the line crosses the grid but exactly on the corner of the box

3. when we have found our point which is (2,6) it means that every 2 pounds of peaches is 6 dollars

4. divide 6/2 and you get 3 dollars!

PLEASE PLEASE HELP (DUE ASAP)! I was struggling a lot with this and I was hoping for an accurate answer! Name the correct angle using the given diagram

Answers

Answer:

Alright Ima jsut say common phrases and do em at the end

Veritcal angles:

Well these angles are equal and always across form each other. Too determine if its a vertical angle, if you see an “x” Like shape, you can draw a maximum of two lines, one horizontal, one vertical. The number those lines tough are vertical the fore the SAME.

Complementary angles:

These are 2 or more angles that add up to 90 degrees. You can have like 20 different angles with different numbers, as long as they add up to 90 degrees. 90 degrees is a right angle so no matter what, it has to equal 90 degrees from all angles.

Supplementary angles:

These are 2 or more angles that add up to 180 degrees or a straight line more common. As long as all the angles add up to 180, its supplementary.

Adjacent angles:

These are angle show lie next to each other. They don’t have anything special, their just next to each other. Ima use an example form the graph. Take for example the angle RNX. XNE is adjacent, its lies right next to it. Another Example could be KND. DNE is adjacent, right next to it.

1) ANR

2) KNE

3) KND

Step-by-step explanation:

it dosnt say it starts with any water in it and I have no numbers to base this so I'm gonna say that it passes through the origin and unit rate depends on how many gallons a minute just take 2 minutes and 1 gallon right well that would be .5 for unit rate hope this helps you

Answers

Answer:

1a)81 b)54 c)27 d)0

Step-by-step explanation:

for number one the answer is 27 x what is given

Answer:

a) 8; b) 12; c) 6; d) 130.3 cm

Step-by-step explanation:

You want the number of small cubes painted on 3, 2, 1, and 0 faces if the outside surface of a cube comprised of 27 small cubes is painted. You also want the height of 200 L of water in a tank of 50 cm radius with a 20 cm radius hole in the middle.

1. Cubes

The number of cubes painted on 3 faces is the number of corner cubes: 8.

The number of cubes painted on 2 faces is the number of center-edge cubes, 12.

The number of cubes painted on one face is the number of center-face cubes, 6.

The number of cubes with no painted faces is the number of cubes buried inside, 1.

The painting is ...

3 faces: 82 faces: 121 face: 60 faces: 1

The total is 27, as it should be.

2. Height

The area of the base of the part holding water is ...

π(50² -20²) = π(2500 -400) = 2100π cm²

The height of 200 L of water will be h, where the volume of the figure is ...

V = Bh

V = (2100π cm²)h = 200·1000 cm³

h = 200/(2.1π) cm ≈ 30.3 cm

The height of the water in the tank will be about 30.3 cm.

Additional comment

When working with volumes in liters, it is often convenient to work with dimensions in decimeters (dm), where 1 dm = 10 cm. This is because 1 dm³ = 1 L.

Here, the area is π(5² -2²) = 21π dm², so the height is (200 dm³)/(21π dm²) ≈ 3.03 dm = 30.3 cm.

The average surface temperature of a red giant star is much cooler than that of a white dwarf star. Suppose a white dwarf has a surface temperature of 1.2 x 10*4 Kelvin (abbreviated K), which is 4 times the temperature of a red giant star. WHat is the surface temperature of the red giant star?

Answers

Answer: 3000 Kelvin

Step-by-step explanation

Let the surface temperature of the red giant star = x

Surface temperature of a white dwarf star = 4x

4x = 1.2 × 10^4 K

= 1.2 × 10,000 K

= 12,000 K

4x = 12,000 K

x = 12000 ÷ 4

= 3,000 K

A rhombus has sides of length x + 6 inches and a perimeter of 49 inches. Which equation represents this situation?

Answers

Answer:

Step-by-step explanation:

The equation representing this situation is 4( x + 6 ) = 49.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a rhombus has sides of length x + 6 inches and a perimeter of 49 inches.

The equation can be written as,

4 ( x + 6 ) = 49

The perimeter is given as,

4 x side = perimeter

4 x ( x + 6 ) = 49

4 ( x + 6) = 49
