It remained 720! not 50 so it was 240 x 3 = 720 and then 240 x 2 = 480

I got 480! That wolfram guy got me a bit confused... But ya I got it right z

7(c) was not 2.61m. It wanted a 145% increase and 2.61m is only a 45% increase. You needed to find 100% of 1.8 (double it) and find 45% of 1.8. Add these two values together (3.6m and 0.81m) to get 4.41m.


Damn that makes so much sense :frown: guess that was wrong then
Do you know how many marks it was?

It said the ski's could be 145% of what his height is or whatever. His height accounts for the 1st 100% so the only extra bit needed is the 45%!!!
2.61m is correct

it said round to 1 decimal place, 3.7 was small but 3.75 was the closest so you round up right?

What if we put 9/20 instead of 0.45 for 1b?


I did that too, asked my maths teacher he said that's fine
Ah man, I got 300 pixels for 8b
Original post by muchunknown
Please expand (3-X)(-3x-4) for me mate and prove that I am right


-9x-12 +3x^2 +4x
3x^2 -5x -12

So you are wrong

Anyone got the foundation paper answers?
What was the cumulative frequency answer?
according to this i got 100 marks but i got 80.8 for the least question, do i still get full marks?
You calculated Angle ABC rather than Angle BAC which they asked for if you got 40.0
The answer was 80.4
