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)

Part A:   42° < x < 176°

Part B:  See Explanation

Part C:  No

Step-by-step explanation:

Required temperature of benzene to ensure it remains liquid = x

Boiling temperature= 176°F

Freezing Temperature= 42°F

So the inequality can be written as:

42° < x < 176°

(GRAPH IS ATTACHED)

The Red shaded region represents all the possible value.

The Red Open circles represent boundaries of the solution. The values not included in the solution

As it is necessary for benzene to stay in liquid form for the research, it should always stay above 42°F.

If the temperature of the building fell to 20°F , research cannot be conducted as benzene will freeze.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
