HELP MEE plz.. i have a timed test and would love some help and plz answer all of them

i thinks its C sorry if im wrong

Step-by-step explanation:

It takes so long to answer and explain 5 questions, you know

A chef knows that ground beef used for hamburger is safe to eat once it reaches at 160 degrees Fahrenheit.

So under 160 degrees Fahrenheit temperature, at which chef will not allow the hamburger to be served will be represented by the inequality t < 160.

Similarly chef will not allow hamburger to be served above 170 degree Fahrenheit, so the inequality will be t > 170

So as per statement of the question graph representing the condition under which chef will not allow the hamburger to serve will be Graph number A.

Let c denote the  number of ounces of clay that Elisa uses to make one vase of either size.

Given statements are: To make a small vase, Elisa uses no more than 4.5 ounces of clay.

The words "no more than" implies "less than or equals to"

hence, for small vase c must be less than or equals  to 4.5 oz, which gives

To make a large vase, she uses at least 12 ounces of clay.

The word "at least" means "more than or equals to"

hence, for large vase c must be more than or equals  to 12 oz, which gives

Combining (1) and (2), we get

c ≤ 4.5 or c ≥ 12

To qualify for a role in a play, an actor must be taller than 64 inches but shorter than 68 inches.

⇒The inequality 64 < x < 68, where x represents height,gives the range of height.

⇒In other words range of height can be x > 64 and x < 68 , such that both conditions are applied to single actor.

[with the use of or it will appear to give priority by actor to follow any 1 conditon]

Looking at the number line, it is visible that the circular marks at the ends of the shaded region are shaded as well, not empty. This indicates that the values that these marks lie on, 55 and 65, must be included in the range. The only option that fits this is A, a temperature range within 5 degrees of 60 degrees Farenheit. This is because 5 degrees less than 60 degrees is 55, while 5 degrees greater than 60 is 65 degrees.

Given  : If a bus driver leaves her first stop by 7:00 a.m., her route will take less than 37 minutes. If she leaves after 7:00 a.m., she estimates that the same route will take no less than 42 minutes.

We have to represent the given situation using inequality and we have to choose the correct option from the given options.

the time it takes to drive the route is r,

Consider

Situation 1)  If a bus driver leaves her first stop by 7:00 a.m., her route will take less than 37 minutes.

This can be represented using inequality as  r < 37

Situation 2)   If she leaves after 7:00 a.m., she estimates that the same route will take no less than 42 minutes.

This can be represented using inequality as  r ≥ 42.

This means he can take either   r < 37  or r ≥ 42. he cannot take the time in between .

Hence, option (1) is correct.

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
