1. (Original post by Waveyalex)
An A will be 130/131
it depends tho cos the exams were quite easy so the boundaries will be higher

nooo you can't cancel it, 3-x isn't the same as x-3 that's like saying 3-5 is the same as 5-3

What I did was factorised it to (3-x)/(3-x)(-3x-4) then cancelled out to get 1/-3x-4
3. I got 30.1 to 1dp because the whole angle was 60.1 but x was not incliding the 30 so it was 60.1 minus 30
4. Guys what was the answer for the mean question I think I had 7. Something?

me too
I rounded it up to 0.30 and -2.30. If I am right the question stated to 1 decimal place?
6. Multiplying algebraic expressions - 30abc
Is this one definitely right? Because my friend seems to think that it's wrong :/
7. what is the answer to the sector question?

I got 5.2 :/
8. What was the pentagon answer?
9. The exact Answer for the trial and improvement was 3.7504 which is obviously closer to 3.8 then 3.7 so the answer is 3.8
X= 3.8
10. (Original post by 34908seikj)
Wasn't the last question like 1/2 * 7 * 8 Sin(X) = 18

56Sin(x) = 36

Sin^-1(36/56) = X

x = 40

???

I think I did it wrong then.
What you've done is correct but this is only part of the method as this gives a different angle to the one it asked, so there was more working
Multiplying algebraic expressions - 30abc
Is this one definitely right? Because my friend seems to think that it's wrong :/
Yes that's right I got that to.

thats what i thought but everyone has seemed to put the other one
If you do it correctly it works

eg. 6 - 4 is the same as -4 + 6
13. Omfg I've never done this well before

What did people get for the parallel line question?
144 degrees??
15. whoever created this needs to hurry up, and also question 25 is 80.1, period
16. for steam and leaf can i write 45%
17. I got like 45 for the last one kinda annoyed now cause i messed up the non-calc. guess im most likely gonna fail maths.
18. did the probability question on the stem and leaf have to be a decimal?
could it have been a fraction?
19. (Original post by CaSweeney)
Sorry but it's wrong, the answer was 3.7
3.8 is correct

3.7 = Small
3.75 = Small
3.8 = Big

Always the odd one out, regardless how close it is technically.
20. That paper was amazing, had a good 1 hr sleep too!!
