It would be really useful if you could remember the question numbers
1. Order numbers correctly and include a key
b) 0.45
2a. 30abc
b. 3(y+2)
c. x^2-3x
3. x=9.25
4. Smallest packet was best value for money because it was cheapest per bag of crisps
5. Green- 0.09 Red- 0.36
6a. 20.3
b. 68.04kg
c. 2.61m
7. 3.8
8a. 4:3
b. 480 pixels
9.x= 124 degrees
10. 7.92
11.£42.29
12. x=144 degrees
13.
-2 -1 0 1 2
-1 3 1 -1 3
Draw curve
14. 3 Bars
15. No, because 7766.22 was greater than 7500 pounds
16. 128g
b.11g
17. 30.1
18. 10a^5b^4
b. y= 5p^2-x
19.11 males
20. x= 0.29 or x= -2.29
21. 29.25
22. F.d- 1.6, 3.2, 2.4, 1.8, 0.3
23. -1/3x+4
24. 2x/(x+1)(x-1)
25. 80.4
Q15 I dont agree
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

For 11.I put £42.28 - did I round wrong? 😲
6. I cant remember what the questions were so i cant remember what i wrote down😂🙄

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 guess that was wrong then
Do you know how many marks it was?
8. (Original post by s_ovo)

So was mine! Did we do it right or is the zig zag thingy wrong?
9. !!! IMPORTANT !!! ****
LAST QUESTION CAN BE BETWEEN 80.0-80.4 DEPENDING ON HOW YOU ROUNDED YOUR ANGLES WORKED FROM 1/2absinC, SINE, COSINE ETC
10. (Original post by Elleee1234)
its was the one where you had top work out x for the permiter for the recentangle
x+4 X x i think x= 5 i dont acuatly know if thats right
I got 9.25 ffs, I've failed the whole paper guys. Prepare for my funeral

I think the answer is £42.28.

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
13. it said round to 1 decimal place, 3.7 was small but 3.75 was the closest so you round up right?
14. (Original post by Jf1234)
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
15. Ah man, I got 300 pixels for 8b
16. (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
17. Anyone got the foundation paper answers?
18. What was the cumulative frequency answer?
19. according to this i got 100 marks but i got 80.8 for the least question, do i still get full marks?
20. You calculated Angle ABC rather than Angle BAC which they asked for if you got 40.0
