I wrote 100% working out on every question due to paranoia haha, used AAA similarity cause the top and base of a cylinder is parallelIm confused about q16 i) do you simply write similar triangles? I lost 9-11 marks.

I'll bet one rep. (Assuming this is allowed.)want to put a wager on me getting 95+? hehe
i reckon 94 goes to 95I think i got either 94/95, anyone know how this will do as an examination mark? paper seemed OK so maybe the same?
87~89what u reckon an 83/84 raw mark will align to?
i did exactly what you did tried using pythagoras but then i said to my self this is to easy to see for a 16 so i split it up and realised the similarities hahahWhat made you guys think similar triangles.
For me: i initially though of trying pythagoras and some other shit. It was only right at the end i saw the similar triangles and by that time it was too late for me to do the question in 30 seconds.
I did Q10b of the 2010 Sydney Grammar trial yesterday and it was a VERY similar question which required the same approach and making similar triangles seemed the most straight forward way of eliminating 'y'.What made you guys think similar triangles.
maybe low 90s, around 93?i did exactly what you did tried using pythagoras but then i said to my self this is to easy to see for a 16 so i split it up and realised the similarities hahah
what do you reckon 88 raw will align to btw?
I spent 30 minutes on it until I remembered that paper. I am extremely glad that I went through Q16/10's.I did Q10b of the 2010 Sydney Grammar trial yesterday and it was a VERY similar question which required the same approach and making similar triangles seemed the most straight forward way of eliminating 'y'.
I made this more complicated than it should have been. I did the area of the rectangle HR = 1/2(HR) + xy + 1/2(x)(H-y) + 1/2(y)(R-x) then rearranged for y. Also tried pythagoras and i was like wtf so i stopped.What made you guys think similar triangles.

http://community.boredofstudies.org/showthread.php?t=344092Anyone got the paper? Wanna compare but word from students and they said it was not hard.
Wrote down the eqn of the Volume of the cylinder and compared it to the one that they gave us. Noticed that their answer didn't have a 'y' but R and H instead, so u had to find an eqn that related y to R and H. Similar triangles took me a minute to figure out maybe cause its similar to rates of change Qs in 3u.What made you guys think similar triangles.

the shit that general math students do... makes me wonder if sy37 is autistic.*EDIT* HAHAHAHA I DONT EVEN DO 2U!!
