1) It says he pours an equal amount into the first 7 beakers after pouring 16mL into the 8th so 70/7 = 10mL per beaker for the first 7.
2) If students rotate through 3 activites, each for 8 minutes, 3*8 = 24 minutes total. If it starts at 11:15, 24 minutes after that would be 11:39 (this represents the time they stop). If lunch starts at 12, there will be 21 minutes between the end of gym activities and the beginning of lunch.
For clarification, < is less than, > is greater than, and then there is =.
A. So you have to take the percent of each number first.
50% of 20 = 0.5 x 20 = 10
40% of 30 = 0.4 x 30 = 12
Then put in the appropriate sign.
10 < 12
B. 75% of 12 = 0.75 x 12 = 9
30% of 20 = 0.3 x 20 = 6
9 > 6
I believe your answer would be c.
Odd, even or neither:
<span>if </span>
<span>f(-x) = f(x) => even </span>
<span>f(-x) = -f(x) => odd
</span>
