Thank you.

a/n = n/49a

49a^2 = n^2
n = +7a or -7a

Sandunes's son (in the maths olympiad thread) is going.
Is yours?

I read the details saying all finalists will attend .... does that mean all the 500+ who got into round2 or only the Gold/Silver awards? DS went for round 2, but till now no news....so thought I better find out

[shurley197323]

No. Different. Mine is DD. No news from the school either. The prize giving should be 15 oct but still no news? Maybe I will check with the school later. I also thought all 500+ are attending too.

Thanks cwc, I will go to that thread to check.

Shurley,
thanks for the info. Till today, no news still.....so i believe the school is not planning to let the students go too. Well, no issue....just wait for school to give it out then.
