Find the total points for each group:
31 students averaged 82, so the total points were 31 x 82 = 2542
2 students averaged 88, so the total points were 2 x 88 = 176
Now add the total points and divide by 33 students (31 +2):
2542 + 176 = 2718
2718 / 33 = 82.36
The average is 82.36 ( Round as needed).
, so you insert the proportion and get 18. When the tank is three-fifths full, it contains 18 gallons of gas.
The answer is 80%
<span>If Gary has 5 hours of free time per day, he has 35 hours of free time per week.
1 week = 7 days
1 day = 5 h of free time
1 week = 7 * 5h of free time = 35h of free time
</span>Gary spends 14 hours per week on the Internet <span>and 14 hours per week playing video games. That is total 28 hours (14 + 14 = 28)
So, the percent of </span><span>his free time is spent on the Internet and playing video games is:
28/35*100% = 80%</span>
This is simplifying square root expressions. It is hard for me to describe the procedure on my computer but I can tell you the answer.
The answer is choice 2. Always remind yourself to simplify and to group same square roots.
