can anyone help me with question 17 part c , question 18 part c and question 22 of may/june 2011 paper 11

17, c): AFB=180-(38+110)= 32, n then ABF=180-(26+38)=122

18, c): Well for in order to do this, you first have to do part (b), and find the nth term, to find it, use the following link(second method):
https://sites.google.com/site/urbangeekclassroomsg/emath-classroom/number-sequences
and then the formulae u get, substitute the values into part c......

22: Expression= Are of rectangle + area of semi-circle
=(20 *60) +1/2 ( Pie * 30^2) -------> pie is the actual sign, and 30 is squared here!!!
= 1200 + 450(Pie)

Part b): 1/8(2*Pie*30) + 20 + 20 + 1/8(2*Pie*10) ------> solve it and ull get ur answer!!


Hope it helps!!

Haven't done this topic in school, i think.

vectors dude..still its the question thts the real deal not the study of the topic because the concept provided is pretty simple in the topic ..

aint tht contradictory coz puzzles do involve maths also

Not all of them. Only a few.
And they involve only elementary maths. Not difficult stuff.

Not entirely relevant to this thread but for all u math lovers...U wud need a thought shower on this one..Can u solve this..Just to provoke u all,i challenge u (By the way ,did it in abt 2 days u know well concentrating on it for abt 2.5 hrs in total,estimation )..Have funView attachment 31293View attachment 31293 open in new thread if u want to..But solve it entirely by urself..cheers

Hi please can you help me to solve this relative velocity problem:
An aircraft is flying due south at 350kmper hour.The wind is blowing at 70km per hour from the direction x degrees,where x degrees is acute.Given that the pilot is steering the aircraft in the direction 170 degrees,find
(1)the value of x degrees
(2)the speed of the aircraft in still air

Take the mid-value of each given time and convert hours into minutes.
Add up all the times: 175*5+185*14+195*7+205*4=5650
Divide by total members: 5650/30=188.33
Take to the nearest minute and convert back into hours: 188 minutes or 3 hours and 8 minutes

I have no idea why assumed mean was given there as I haven't studied Stats, I solved it all without it.

But the Process Show up Wrong

I don't like practicing maths and i don't do that.
So can i get an A* simply by listening to the school lectures, and seeing questions being solved by the teacher on the board?

You dont need to do that either. just sit back, eat, drink, party and the A* will come flying to you -_-
