1. (Original post by Szuszy2002)
I said 9 out of 20 but as a fractition
I don't understand why ppl don't simplify the fraction? You have a calculator? All you had to do was hit sd

Reps are not necessary but would be appreciated

It would be really useful if you could remember the question numbers
1. Order numbers correctly and include a key
b) 9/20=
0.45
2a. 5a*2b*3c =
30abc
b. Factorise fully 3y +6 =
3(y+2)
c. Expand x(x-3)=
x^2-3x
3.
x=9.25
4. Smallest packet was best value for money because it was cheapest per bag of crisps
5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
0.4+0.15+4x+x=1
0.55+5x=1
5x=0.45
x=0.09
4x=0.36
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
16a and b were estimates so it was 130 and 10

did anyone else get 28.9cm for the perimeter of the shaded region
4. (Original post by webb-tom2)
I missed the key for question 1... Of all the marks to lose it just had to be that xD
I also forgot the key ((((((

i am also worried i put 11/20 instead of 9/20.

i might be overthinking it
5. Which question was the question asking on price of petrol and parking total cost? i got something like £8
6. Anyone remember the questions for 6a, 7 and 10???
7. I got the medium packet for the crisps one! I got the small one first but then o crossed my working out and changed the numbers around on the calculator and got the medium one to be the cheapest! I'm so confused - that's 4 marks DOWN THE GUTTER. I HAVE FAILED THIS PAPER AND THE NON CALC PAPER TOO! WOOO!!!!
8. (Original post by Disfuligee)
Actually 2x/(x+1)(x-1) is more simplified
Literally every year the exam board allows both lol
9. (Original post by Oasis61)
How many marks would this get
3-x/(2x+4)(x-3)

Posted from TSR Mobile
Sorry but I think that is none because that does not multiply out to 3x^2-5x-12 or whatever the original was

Please would you be able to put how many marks each answer is worth? Thank You
Also I got 126 degrees for question 9
11. (Original post by xsophie_daviesx)
For the simplifying quadratic fraction I got -3x-4
Anyone else???
sameee
12. Can you write a probablity as a percentage for the second I did 9/20 X 100= 45% would that be fine?
13. (Original post by SweetStarlight14)
It was the perimeter that was 45cm, so 4x+8 = 45, meaning x = 9.25.
thank you so much, i hope that's right cos i got that too

True

Which question was the question asking on price of petrol and parking total cost? i got something like £8
How could you get 8? With £3.50 a day for parking, for 5 days, even the car park charge is higher than £8, let alone with the fuel as well

Question 11.
18. (Original post by DrPeter)
If I have the correct numbers,This is one way of doing last Q

Area = ( absinC)/2Sin-1 C

= 18x2/(7x8)= 40.00520088 degrees (DO NOT ROUND)

a^2 = b^2 + c^2 - 2 x b x c= 27.20955764 cm (DO NOT ROUND)

Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

= 80.37550115

= 80.4 degrees
Thank you this is really helpful. I think i see where i went wrong, I thought i was working out just the first angle and thought i was done lol

I said 9 out of 20 but as a fractition
