Achemist 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 bowling point of benzene is 176 degrees f , and the freezing point is 42 degrees f .
part a: write an inequality to represent the temperatures the benzene must stay between to ensure it remains liquid.
part b: describe the graph of the inequality completey from part a. use terms such as open / close circles and shading directions. explain what the solution to the inequality represent.
part c: in february, the building's furnace broke and the temperature of the building fell to 20 degrees f. would a chemist have been able to conduct a research with benzene on this day? why or why not?

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

50x5=$250

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
