An architect is designing a house for the Frazier family. The Fraziers have asked that the cost of

the house be about $175,000 and are willing to deviate from this price no more than $20,000.

19 A) Write an open sentence involving an absolute value.

Answers

Answer:

║x - 175,000║≤ 20,000

Step-by-step explanation:

Let x be the amount the Fraziers are willing to pay. Since the house costs $175,000 and they are willing to deviate from this price no more than $20,000, so x = $175,000 ± $20,000.

So, x - 175,000 = ± 20000

║x - 175,000║= 20,000

But we require

║x - 175,000║≤ 20,000

which is our required open sentence.

Answers

Answer:

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].

What is convex polygon?

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].

c is your awnser

Step-by-step explanation:

Answer:

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.

A rectangular room is 3 times as long as it is wide, and its perimeter is 48 meters. Find the dimension of the room.

The length is : _____ meters and the width is ______ meters.

Answers

length is 18 and width is 6

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

Given that

The perimeter of the rectangle is 48 meters.The width be x.The length be 3x.

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.
