UNOFFICIAL MARKSCHEME Edexcel Maths Calculator paper 09/06/2016

how many metal rods was it?? i got bloody 31 idek if thats even right, i just used mass/volume=density don't tell me that was wrong loooool

49 on the non calculator paper counted around 55 on here will that get me a B do you think guys?

Hi I'm going to start and unofficial markscheme so add your answers
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
23.28.9
24a. -1/3x+4
b. 2x/(x+1)(x-1)
25. 80.4

Question 15 did not equal to £7766.22
Because 1st year depreciated by 23%
so 0.77 x 15000 = £11550
then after the 1st year it was 18%
so 0.82 x 11550 = £9471
therefore no it was not more than half

Its 3.7 not 3.8, in the exam i took them away from the needed number and 3.7 was like 3 tenths closer to it than 3.8

It's okay!! You'll only lose like 1mark :P you'll get a mark for the correct table

Does anyone remember the question for 18?????

Did anyone else get 396 (or around there) at some point during the pentagon question?

I did the exterior angles, then the interior ones. Calculated the two interior angles at the bottom, and the two right angles on the symmetrical lines (I think they were right angles)

Finally did 540 - 396oraroundthere

Will I get 0 marks for that answer or maybe 1-2?

Its 3.7 not 3.8, in the exam i took them away from the needed number and 3.7 was like 3 tenths closer to it than 3.8

it was 3 metal rods 😅

Yeah. Silly mistakes I made:
- Used radius instead of diameter for circle perimeter question.
- Used 20 and 40 for lower and upper quartiles rather than 15 and 30 (doh!).
- Got the question with the simplifying the algebraic fraction wrong.

So all in all after realising these mistakes my confidence has taken a dip.

And does anyone recall the Quadratic formula question?

Its 3.7 not 3.8, in the exam i took them away from the needed number and 3.7 was like 3 tenths closer to it than 3.8

What was question 11?
