[Dumsum]

I suck at this kind of maths... I guessed 9 out of the 25 multiple choice, and only answered 1 of the 5 free responses.

Btw, that cake one, anyone else get 75cm^2?

[justchillin]

Yes 80 was correct, as for the triangle one sorry man I dont have my paper anymore... Did everyone get 5 for the second last one also???

 

[thunderdax]

Yep, I got 5 for the second last one. Overall, it was a pretty hard competition this year. I don't think I went very well and i had no clue on the last question.

 

[Jago]

5 was the answer for the 2nd last question.

 

[PtolemysPenguin]

It was pretty hard this year. For the senior, the last 5 answers were 80, 401, 20, 5 and 13. (The number for the last one is 130)

5 was the answer for the 2nd last question.

wow, how did you get all those answers lol.. smart..~

 

[Jago]

Spoiler

i have no idea why

 

[thunderdax]

I thought the one where the answer was 401 was too easy. It only took less than a minute.

2(root 2 + 1) or something like that.

 

[David_O]

The q with the functions.t = f(t)

 

[pLuvia]

The q with the functions.t = f(t)

how did you do that?? i didnt even understand it lol

 

[PtolemysPenguin]

2(root 2 + 1) or something like that.

This is correct.

 

[thunderdax]

how did you do that?? i didnt even understand it lol

If I remember correctly, since f(f(t))=f(t), f(t)=t and go from there.
