8 gallons= 128 cups
20 guests x 2 cups each= 40 cups will be gone
128-40= 88 cups left over
88 cups= 5.5 gallons of punch left at the end of the party.
It is a negative correlation.
Ratio of 30-60-90 triangles in terms of side lengths is 1-

-2
So, the side across the 30-degree angle is 6.25.
Thus, the side across the 90-degree angle (hypotenuse) is 12.5.
Answer:
9x2=18 53x5=265 60 divided by 10 is 6 18+265+10=293
