Cynthia besch wants to buy a rug for a room that is 18ft wide and 35ft long she wants to leave a uniform strip of floor around rug she can afford to buy 528 ft of carpeting what dimensions should rug have

Answers

Answer:

rug long = 34 ft

rug wide = 17 ft

Step-by-step explanation:

given data

wide = 18 ft

long = 35 ft

area of carpet = 528 ft

solution

we get here area of floor that is

and we consider length of carpet = 35 - 2x

and width = 18 - 2x

(35 - 2x) × (18 - 2x) = 528 ...................1

solve it we get

x = 25.5 and x = 1

we choose 1 ft. as the width of the strip

so rug long = 35 - 1 = 34 ft

and rug wide = 18 - 1 = 17 ft

write a rule for the function below x 2 4 6 y 8 6 4

Answers

Answer:

y= -1/2x+2

Step-by-step explanation: Our "y-intercept" (where x = 0) acts as the foundation of our function here.

We can extrapolate from what we have here...if x is 0, y is going to be 2.

So, we start at 2 for y, and every time we decrease x by 2, y increases by 1.

If we decrease x by just 1, y increases by ½.

This also goes in the opposite direction. Increase x by 1, decrease y by ½.

We can write the change in y as -½x.

That change is being added to our original value of 4, of course.

Answers

Answer:

x = 21

y = 15

Step-by-step explanation:

Exterior angles on the same side of the transversal are supplementary

So, 3x - 16 + 6x + 7 = 180

9x -9 = 180

9x = 189

x = 21

11y - 32 = 6x + 7 since the angles are vertical angles

11y - 32 = 6(21) + 7

11y - 32 = 126 + 7 = 133

The x and y value from the given system of equations are 7 and -3 respectively.

What is a linear system of equations?

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The given simultaneous equations are 3x-2y=27 ------(I) and 3x-y=24 ------(II) .

Subtract equation (I) from (II), we get

3x-y-(3x-2y)=24-27

⇒ y=-3

Substitute y=-3 in equation (I), we get

3x-2(-3)=27

⇒ 3x=21

⇒ x=7

Therefore, the x and y value from the given system of equations are 7 and -3 respectively.

x = 1, x+3 = 4

x = 2, x+3 = 5

x = 3, x+3 = 6

x = 4, x+3 = 7

For 2x

x = 1, 2x = 2

x = 2, 2x = 4

x = 3, 2x = 6

x = 4, 2x = 8

You will use the values of x and y = x+3, and the values of x and y = 2x to draw the diagram of the lines as shown in the attached image

Evaluate the function.f(x) = -2x + 2x 20Find f(-8) The Importance of ElsewherePaul TherouxRead the passage, then answer the question.As a child, yearning to leave home and go far away, the image of my mind was flightmy little self hurrying off alone. The word travel did not occur to me, nor did the word transformation, which was my unspoken but enduring wish. I wanted to find a new self in a distant place, and new things to care about. The importance of elsewhere was something I took on faith. Elsewhere was the place I wanted to be. Too young to go, I read about elsewhere, fantasizing about my freedom. Books were my road. And then, when I was old enough to go, the roads I traveled became the obsessive subject in my own books. Eventually I saw that the most passionate travelers have always also been passionate readers and writers. And that is how this book came about.2 The wish to travel seems to me characteristically human: the desire to move, to satisfy your curiosity or ease your fears, to change the circumstances of your life, to be a stranger, to make a friend, to experience an exotic landscape, to risk the unknown, to bear witness to the consequences, tragic or comic, of people possessed by the narcissism of minor differences. Chekhov said, If youre afraid of loneliness, dont marry. I would say, if youre afraid of loneliness, dont travel. The literature of travel shows the effects of solitude, sometimes mournful, more often enriching, now and then unexpectedly spiritual.3 All my traveling life I have been asked the maddening and oversimplifying question what is your favorite travel book? How to answer it? I have been on the road for almost fifty years and writing about my travels for more than forty years. One of the first books my father read to me at bedtime when I was small was Donn Fendler: Lost on a Mountain in Maine. This 1930s as-told-to account described how a twelve-year-old boy survived eight days on Mount Katahdin. Donn suffered, but he made it out of the Maine woods. The book taught me lessons in wilderness survival, including the basic one: Always follow a river or a creek in the direction the water is flowing. I have read many travel books since, and I have made journeys on every continent except Antarctica, which I have recounted in eight books and hundreds of essays. I have felt renewed inspiration in the thought of little Donn making it safely down the high mountain.4 The travel narrative is the oldest in the world, the story the wanderer tells to the folk gathered around the fire after his or her return from a journey. This is what I sawnews from the wider world; the odd, the strange, the shocking, tales of beasts or of other people. Theyre just like us! or Theyre not like us at all! The travelers tale is always in the nature of a report. And it is the origin of narrative fiction too, the traveler enlivening a dozing group with invented details, embroidering on experience. Its how the first novel in English got written. Daniel Defoe based Robinson Crusoe on the actual experience of the castaway Alexander Selkirk, though he enlarged the story, turning Selkirks four and a half years on a remote Pacific Island into twenty-eight years on a Caribbean island, adding Friday, the cannibals, and tropical exotica.5 The storytellers intention is always to hold the listener with a glittering eye and riveting tale. I think of the travel writer as idealized in the lines of the ghost of Hamlets father at the beginning of the play:6 I could a tale unfold whose lightest word Would harrow up thy soul, freeze thy young blood, Make thy two eyes, like stars, start from their spheres, Thy knotted and combined locks to part And each particular hair to stand on end.7 But most are anecdotal, amusing, instructional, farcical, boastful, mock-heroic, occasionally hair-raising, warnings to the curious, or else they ring bells like mad and seem familiar. At their best, they are examples of what is most human in travel.The following question has two parts.
