The chemistry teacher set out a 5 pound jar of salt at the beginning of the day. If each student needs 27.6 grams of salt for an experiment, how many students can perform the experiment before the jar is empty? (hint: 1lb=454grams)

82

Step-by-step explanation:

454x5= 2270, 2270/27.6= 82.2463768116

82 students

Step-by-step explanation:

In this, the first thing you should do is convert the five pounds to grams, which is 2270 grams. Now, all you need to divide 2270 by 27.6 to get the number of students because each student uses 27.6 grams and there 2270 grams being set each day. This gives you 82.2463768116 technically, but you should just round up, and that gives you 82 students. I hope this helped :D

the two may have that, even a breakdown is probably offered

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
