A chemist is researching different sustainable fuel sources. She is currently working with benzene, which must be in liquid form for her to successfully conduct her research. The boiling point of benzene is 176° F, and the freezing point is 42° F. Part A: Write an inequality to represent the temperatures the benzene must stay between to ensure it remains liquid. (2 points) Part B: Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the inequality represent. (4 points) Part C: In February, the building's furnace broke and the temperature of the building fell to 20° F. Would the chemist have been able to conduct her research with benzene on this day? Why or why not? (4 points)

Step-by-step explanation:

Part A:

176>x>42

because the tem cant be 176 or higher, and it cant be 42 degrees or lower.

Part B: you must describe the graph of inequality which will look something like this:

Part C:

Because the temperature cannot go below 42 before it freezes, she would not have been able to conduct her research

Step-by-step explanation:

There is no firm rule that says an essay needs to have a set number of paragraphs, but an essay must be a minimum of three paragraphs. There are a lot of people who say an essay should be five paragraphs, but it’s an extremely limiting rule, and unless you’ve been instructed to write a five paragraph essay, there’s no reason to stick to it.

As a rule, you’ll write your essay in three main parts. First, you’ll introduce your topic to your reader. Next, you will have body text in which you discuss the topic in more detail, and finally, you’ll have a conclusion that tells your reader what you were able to see after looking into the facts or thinking through the topic.

In its simplest form, an essay can consist of three paragraphs with one paragraph being devoted to each section. Proponents of the five paragraph essay say that the body text should consist of three paragraphs, but in reality, it’s fine to write more or fewer paragraphs in this section.

Guessing How Many Paragraphs Before You Begin

This is a rule of thumb, which means it won’t always work quite that way, but it’s handy all the same. In academic work, your paragraphs are likely to be a bit longer than most of the ones you see in this blog post. On average, there are usually 100 to 200 words in a paragraph. So if you’d like a guesstimate, you can assume that a 1,000-word essay will have between five and ten paragraphs.

What Points Do You Have to Cover?

Another, less limiting and more accurate way to work out how many paragraphs you need to cover your topic is to look at the main points you have to cover in the body text. A paragraph contains all the ideas that support or explain a single concept.

When you are planning your essay, you will think of or research the main elements that are needed in the body text. It would be safe to assume you need at least one paragraph for each of these. Of course, if there is a lot of information to cover in order to explore each area, you may need more.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

40 is the final : )
