Lainey bought a set of 20 markers for $6
What is the cost of 111 marker?

Answer:

13

Step-by-step explanation:

1980 = ( n - 2 ) * 180

n - 2 = 11

n = 13

A convex polygon has 13 sides when the interior angle sum is [tex]1980^{0}[/tex].

A polygon is called a convex polygon when no line segments between the points, goes inside. The boundaries of the convex polygon do not go inside and all the vertices are pointed outside away from the center. The interior angles of a convex polygon are less than 180°.

Given a convex polygon

For a convex polygon with n sides, the interior angle sum is [tex]180^{0}[/tex] × [tex](n-2)[/tex]

Let [tex]180^{0}[/tex] × [tex](n-2)[/tex] = [tex]1980^{0}[/tex]

⇒ n - 2 = 11

⇒ n = 11 + 2

⇒ n = 13

Thus, a convex polygon has 13 sides when the interior angle sum is [tex]1980^{0}[/tex].

Answer:

simply need to change its sign

Step-by-step explanation:

To find the opposite value of an integer you simply need to change its sign. Meaning that if a given integer is positive then you change the positive into a negative. This would give you the opposite value of that integer which is located at the same distance from 0 but on the other side of the number line. For example, the opposite value of 5 would be -5, while the opposite value of -8 would be 8

Step-by-step explanation:

Find the integer that is

Answer:

31) 11

32) 14

33) 30.6

34) 16.5

Step-by-step explanation:

31) GW is half the length of UW and UW is equal to 22. So, 22/2 = 11

32) VY is half the length of VX and VY is equal to 7. So, 7 x 2 = 14

33) VR is half the length of VX and VR is equal to 15.3. So, 15.3 x 2 = 30.6

34) UH is half the length of FH and FH is equal to 33. So, 33/2 = 16.5

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Answer:

30

Step-by-step explanation:

In this picture, the angle, 30 degrees, is a part of the whole. we are looking for the value of X.

First we can take off 45 degrees, since the angle is lower than 30 degrees

Now we can take off 15 degrees, since the angle is too small.

And we can also take off 10 degrees since its way too small.

2x mean 2 times X.

The overall measurement is a 90 degree angle, indicated by the box.

90-30= 60

30 * 2 = 60.

The correct answer is 30.

Answer:

170cm

Step-by-step explanation:

Given data

perimeter of 600 cm

let the Length be x

L=x

W= x-40

P=2L+2W

600=2(x)+2(x-40)

600=2x+2x-80

600= 4x-80

600+80= 4x

680= 4x

divide both sides by 4

x= 680/4

x=170

Hence the length is 170cm

The circumference of Sophia's garden is 43.98

Step-by-step explanation:

The length and width are 18 meters and 6 meters respectively.

Given that

We know that

The perimeter of the rectangle be

48 = 2 (length + breadth)

48 = 2(3x + x)

48 = 6x + 2x

48 = 8x

x = 6

So, the width is 6 meters.

And, the length be 18 meters.

Therefore we can conclude that The length and width are 18 meters and 6 meters respectively.
