May I ask you what year you are in or grade for the Americans?
This is already answered and such, but in hopes of not having the confusion we had with yesterdays i will attempt to explain it. Basically... You look at the difference in each term and their differences until you come to a constant number.
There's a new problem.
Yeah, trick question though? I'd assume it would be 10 too..The Adams family have eaten pancakes. There is 1 liter of the liquid pancake mix stuff left. The mother is going to freeze it. The mother knows it takes exactly 5 scoops to fill the box she is putting it in. But she can't find the scoop, so she uses a smaller scoop. This scoop is half the size of the first one that she couldn't find. Both scoops are half-sphere shaped.
How many scoops would the mother need to fill the box?
lol at the answers
Assuming that the Scoop is a perfect half sphere

For enslaved.
damn, I am never first. At least I am most readable :P
edit:
Also made a mistake swapping the 4 and 3, oh well. Answer is correct.

The main part its (r/2)^3 which makes the difference to be 8x r' the front part doesn't matter as it is constant in both

@ masterbb, what did you type that up in? Mathematica?

New problem. 15th can still be answered.
was my previous answer not correct?
Working on: Tithe Farmer
You meant qns 16?
I get the same ans as masterBB for 15, though a much shorter way
fill rate = 1 bathtub per 15 min (1/15)
fill rate - drain rate = 1 bathtub per 60 min (1/60)
drain rate = 1/15 - 1/60 = 1/20 (1 tub / 20min)
time needed to drain 1 bathtub = 20min
For qns 16, what 'cone' are you referring to? The bathtub is a cone?

the height of the water level is variable to the radius of the cone

Im confused on this one... What is the height of the water if the cone is turned the other way? ( like this -- /\ ) or is it meant to say what is the height of the cone?
Either way, height of the water if the cone is flipped around = sqrt2 -1 ~ .41 units
Height of the cone = sqrt2 ~ 1.41 units
