Describe how a newspaper is organized. Why do you think the stories, pictures, advertisements, and cartoons are laid out the way they are?

Answer in paragraph form using 5-7 complete sentences.

Answers

It’s organized on which is more important and which is least important and they Wright about a subject then they put a picture to tell you about it

Answer:

 A newspaper is organized in a logical format. The front page has the most exciting news of the day. The editors determine what is most newsworthy for their readership. The A-section contains world and national news; the B-section contains local news. Some of the categories include entertainment, local news, national news, classified advertisement, and neighborhood news. They are laid out the way they are because they want to catch the reader's eyes. They want the reader to look at the newspaper and think "oh that looks interesting."

A linear function models the height of a burning candle. Candle A comes out of the mold at 211 ​mm and is expected to be at 187 mm after 8 hours of burning. The model for Candle B is h=240-8t ​, where h is the height in millimeters and t is the time in hours. What are the initial values for each​ candle? What do the initial values for each candle tell​ you?
Use a pencil and paper. If the candles begin burning at the same​ time, can they ever be the same​ height? Explain.

The initial value for candle A is...... mm

Answers

Answer:

Step-by-step explanation:

h=196 and t=4 hours

196=220-xt, so -24=-xt

24=xt

24=4x

x=6

h=220-6t. units in mm

-------------

For B, 290-5(4)=290-20=270 mm, initial value of height.

Graph the line y=3/2x-1

Answers

U would start at the point -1 and the go up three and go to the side 2

The graph of the equation is attached

How to make the table of values for the graph

To create a table of values for the equation y = (3/2)x - 1, you can choose different values for x and calculate the corresponding values for y. Here's an example table with x-values ranging from -2 to 2:

x y

-2 -4

-1 -2.5

0 -1

1 0.5

2 2

To find the corresponding y-values, substitute each x-value into the equation y = (3/2)x - 1 and solve for y.

For example,

when x = -2, you get y = (3/2)(-2) - 1 = -4.

Similarly, when x = -1, y = (3/2)(-1) - 1 = -2.5, and so on.
