Answer:
3
Step-by-step explanation:
You might think that the volume of a circle is needed to solve this problem but you can do it in a more simplified manner. First figure out how much water 85 marbles displace.
26-20.9=5.1 liters of water
Now, let us see how much water 200 marbles displace.
85 marble x (200/85) = 5.1 liters x (200/85)
200 marbles = 12 liters
We can find the amount of water needed to fill the tank now.
26-12=14 liters of water
answer: 14 liters of water
Add and subtract the second term to the expression and factor by grouping.
4k(y-1)(3y+5)
600-225 = 375 students didn't attended the game.
So, the percentage of the people who didn't attented will be (375/600) × 100 = 62.5%
