In-s [12.5K]

Answer:

8 or 9

Step-by-step explanation:

So, you first need to take 4/5 of 400 (320).  Then, you can count by 75s for a bit

75students; 2chaperones

150; 4

225; 6

300; 8

now, you have 20 students left over...since one chaperone would watch about 37 kids, you can either divide the remaining kids up among the other chaperones, or you can add one more chaperone to watch the 20 kids.  i don't know what the teacher wants, so either 8 or 9 chaperones

If I counted correctly, the answer would be 52/150. You just need to simplify the fraction. I'll recount soon, and update if it changes.

Answer and round to the nearest tenth .<br> <img src="https://tex.z-dn.net/?f=2.1%5Csqrt%7B1.488%7D" id="TexFormula1" title="2.1
Illusion [34]

It is a good idea to get familiar with the operation of your calculator. If you're going to use on-line resources to work problems like this, you can make use of any of several good on-line calculators. Google and Bing search boxes will do calculations for you while observing all the rules of the Order of Operations.

The result of this computation is a number that begins 2.56.... Since the hundredths digit is more than 4, the tenths digit is rounded to the next higher value, from 5 to 6.

Rounded to tenths, 2.1√1.488 = 2.6
