Answer:

12.56

Step-by-step explanation:

The formula for the sum of the interior angles of a polygon is (n - 2) * 180. In this formula, N is the number of sides. So, to find the number of sides that a polygon with an interior angle measure of 10080 has, we'll set the formula equal to 10080.

10080 = (n - 2) * 180

Divide both sides by 180

56 = n - 2

Add 2 to both sides

n = 58

Hope this helps!! :)

Answer:

58 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is 10,080°

n = the number of sides

(2n - 4)90 = 10080

2n - 4 = 10080/90 = 112

2n = 116

n = 58.

Answer:

Discount percent = 43% off

Discount amount (money saved) = $75.25

Step-by-step explanation:

To find the discount percentage:

List price ($175) minus the sale price ($99.75) then divided by the list price ($175) and multiplied by 100 to get the discount percent of 43%.

To find how much money was saved:

List price ($175) minus sale price ($99.75) to get the amount saved, which savings are $75.25 in this case.

I hope this helps :)

Answer:

Step-by-step explanation:

[tex]a_{n}=-2*5^{n-1}\\n=11\\a_{11}=-2*5^{11-1}\\a^{11}=-2*5^{10}\\=-2*50,000,000,000\\=-100,000,000,000[/tex]

Answer:

12.5%

Step-by-step explanation:

Given that,

Initial temperature of a piece of metal = 32°C

Final temperature of the piece of metal = 36°С

We need to find the percentage increase in the temperature of the piece of metal.​ The percentage increase in any value is given by the relation as follows :

[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{36-32}{32}\times 100\\\\=12.5\%[/tex]

So, the required percentage increase in the temperature of the piece of metal is equal to 12.5%.

Answer:

$90.00

Step-by-step explanation:

Given

[tex]c = 45.00[/tex]--- base fee

[tex]m = 15.00[/tex] --- rate

[tex]x = 3[/tex] --- individuals

Required

Determine the total amount paid (y)

The relationship between the variables is:

[tex]Total = Base\ Fee + Rate * Individuals[/tex]

[tex]y = c + mx[/tex]

This gives:

[tex]y = 45.00 + 15.00 * 3[/tex]

[tex]y = 45.00 + 45.00[/tex]

[tex]y = 90.00[/tex]

Hence, the amount is $90.00

Answer:

i think it would be going to C because you dont have what x would be so we could assume that it is 0 and y intersection would be 2

Answer:

mean =16

variance=12.8

standard deviation =3.578

Step-by-step explanation:

mean=np=80×0.2=16

variance= np(1-p)

=16(1-0.2)

=12.8

standard deviation =

[tex] \sqrt{12.8} [/tex]

=3.5777

Step-by-step explanation:

I rounded both numbers and multiplayer them.

Answer:

Step-by-step explanation:

320t=500(t-1.5)

320t=500t-750

-180t=-750

t=25/6

t=4+1/6 hours

So Colby catches up 4 1/6 hours after Shelby left. Since she left at 9am

9+4hours + 10 minutes. So they have travelled the same distance at 1:10pm

Answer:

602.88in²

Step-by-step explanation:

Formula for finding the volume of oblique triangle is expressed as

A = πr²h

Given

radius r = 4in

height h = 12in

Substitute

A = π*4²*12

A = 3.14*16*12

A = 3.14 * 192

A = 602.88in²

Hence the area of the cylinder is 602.88in²

Answer:

71 percent

Step-by-step explanation:

About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. Water is never sitting still.

The area of the earth's surface covered in water will be 63541028.57 square kilometres.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

Given that about 5/7 of the earth's surface is covered with water. About 88957440 km squared is land.

The area covered with water will be calculated as,

Area = ( 5 / 7 )  x 88957440

Area = 63541028.57 square kilometres.

Step-by-step explanation:

Answer:

Step-by-step explanation:

h^2=x^2+y^2, in this case

h^2=8^2+15^2

h^2=64+225

h^2=289

h=17cm

Answer:

17 cm

Step-by-step explanation:

The Pythagorean Theorem: [tex]a^2+b^2=c^2[/tex] where a and b are the legs and c is the hypotenuse

Plug in the values of the legs

[tex]8^2+15^2=c^2\\64+225=c^2\\289=c^2\\c=\sqrt{289} \\c=17[/tex]

Therefore, the length of the hypotenuse is 17 cm.
