a polygon has 10080° as the total interior angle how many sides has the polygon​

Answers

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.

About 5/7 of the earths surface is covered with water. About 88957440 km squared is land. How much in km squared of the earths surface is covered in water?

Answers

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.

What is an expression?

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.

Function g is an exponential function passing through the points (3,–53) and (5,-41), which statement is true over the interval (3, 5),


A. The average rate of change of fis the same as the average rate of change of g.
B. The average rate of change of fis greater than the average rate of change of g.
C. The average rates of change of fand g cannot be determined from the given information.

D. The average rate of change of fis less than the average rate of change of g.

Answers

The statement that should be true is option A. The average rate of change of f is the same as the average rate of change of g.

What is an exponential function?

It is considered to the mathematical function where x should be the variable and a be the constant that we called as the function-based.

Since Function g is an exponential function passing through the points (3,–53) and (5,-41).

So here the average change rate of f should be similar just like the g.

Learn more about function here: https://brainly.com/question/21722094

We can conclude that the average rates of change of f and g cannot be determined from the given information.

Option C is the correct answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

We can calculate the average rate of change of function f over the interval (3,5) using the given table:

The average rate of change of f

= (f (5) - f (3)) / (5 - 3)

= (71 - 59) / 2 = 6

To determine the average rate of change of function g over the same interval, we need to find its equation first.

We can use the two given points to set up a system of equations:

-53 = a(3)^b - 41

-53 = a(5)^b - 41

Subtracting the second equation from the first.

0 = a(3^b - 5^b)

Since 3^b ≠ 5^b, we must have a = 0, which means g is not a valid exponential function passing through the given points.

Therefore,

We can conclude that the average rates of change of f and g cannot be determined from the given information.

Answers

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

A craftsman makes a circular table with a radius of 55
cm A customer asks for a smaller circular table to be made
with a diameter only half as big.
What is the circumference of the smaller table?

Answers

Answer:

Hey mate here is your answer...

Step-by-step explanation:

smaller circular table to be made

with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm

therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm

circumference of circle = 2πr

= 2*3.14*27.5

= 172.7 cm = 27.5cm
