Each polygon is divided into a number of triangles. Find the number of triangles if the number of sides in a polygon is: (a) 6

Answers

Answer:

4 triangles

Step-by-step explanation:

the number of triangles in a polygon is (the number of sides in the polygon - 2)

The number of triangles inside a polygon with six sides are 4.

What is a polygon? What is a mathematical function, equation and expression?               polygon : A polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is that the number of sides in a polygon is 6.

If the polygon has {n} sides, then the number of triangle in a polygon is → (n – 2).For n = 6, the number of triangles would be - (6 - 2) = 4

Therefore, the number of triangles inside a polygon with six sides are 4.

A farmer has 180 bushels of apples for sale at a​ farmer's market. He sells an average of 15 3/4 bushels each day. After 6 ​days, what is the change in the total number of bushels the farmer has for sale at the​ farmer's market?

Answers

If the farmer sells an average of 16 3/4 bushels each day, then after 6 days the farmer would have sold

16 3/4 * 6

We can rewrite the mixed number 16 3/4 as an improper fraction for easier multiplication

16 3/4 = 67/4, so

16 3/4 * 6 = 67/4 * 6

67/4 * 6 = 67/4 * 6/1 = 402/4 = 100 2/4 = 100 1/2 bushels sold after 6 days

If the farmer began with 180 bushels, then after 6 days the farmer has

180 - 100 1/2 = 79 1/2 bushels

I need the perimeter of this triangle. Round to the nearest tenth. Quickly please

Answers

Answer:

The perimeter of the triangle is about 17.1 units.

Step-by-step explanation:

The perimeter of a triangle is the sum of its three side lengths.

We can see that the two legs of the triangle both measure five units.

To find the third segment, we can use the Pythagorean Theorem since the x-axis is perpendicular to the y-axis. Recall that:

[tex]a^2 + b^2 = c^2[/tex]

Where a and b are the two legs and c is the hypotenuse.

Our two legs are 5 and 5. Hence:

[tex](5)^2 + (5)^2 = c^2[/tex]

Solve for the hypotenuse:

[tex]\displaystyle \begin{aligned} c &= \sqrt{(5)^2 + (5)^2} \\ &= \sqrt{2(5)^2} \\ &= 5\sqrt{2}\end{aligned}[/tex]

Hence, our perimeter will be:

[tex]\displaystyle P = 10 + 5\sqrt{2} \approx 17.1 \text{ units}[/tex]

In conclusion, the perimeter of the triangle is about 17.1 units.

8 feet long. The tables will be covered with paper tablecloths that extend
an extra 3 inches over each end (so they can be taped underneath). What
is the total length of paper needed to cover all the tables?

Answers

We have that the total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

From the question we are told that:

Number of tables [tex]n=36[/tex]

Length of table[tex]l=8[/tex]

Extension [tex]e=3 inch =>0.25feet[/tex]

Generally, the equation for the Total length  tables is mathematically given by

[tex]l_t=n*l\\\\l_t=36*8[/tex]

[tex]l_t=288ft[/tex]

Therefore with an extension of 0.25ft at both end we have the Total length of  tablecloths to be

[tex]X=l_t+2(e)\\\\X=288ft+2(0.25)[/tex]

[tex]X=288.5ft[/tex]

In conclusion

The total length of paper needed to cover all the tables is

[tex]X=288.5ft[/tex]

Answers

Answer:

18-n = 4

-n = -14

n = 14

The value of n when n is subtracted from 18 and the difference is divided by n, the result is 2 is 6.

What is Algebra?

The representation of mathematical statements as solutions to problems is the focus of the branch of mathematics known as algebra. Mathematical operations like addition, subtraction, multiplication, and division are combined with variables like x, y, and z to produce a meaningful mathematical statement.

Given:

When a number n is subtracted from 18

=(18- n)

and, the difference is divided by n

=(18 - n)/n

so, result is 2

(18 - n)/n = 2

18 - n = 2n

3n = 18

n= 18/3

n= 6

Hence, the value of n is 6.
