Unofficial mark scheme for Edexcel Maths Paper 1- Higher 2023

If I wrote 4 and 14/16 for mixed fractions instead of 7/8 is it still correct

yes please i did the same someone respond

I'm just making an unofficial mark scheme for us to add too cause I haven't seen anyone else make one. We can discuss the answers in the chat below but I'm gonna add the answers that I've seen on other maths forums for now

- some of the questions may be in the wrong order!

1) division with decimals - 56.4 (3 marks)
2) fractions - 4 7/8 (3 marks)
3)125 surface area of cube is 150 cm2 find the volume (4 marks)
4) frequency polygon (2 marks)
5) pressure(cylinder) question- 3 (3 marks)
6) 20% holiday question - £1200 ( 2 marks)
7)the pentagon question -140degrees (3 marks)
8)
9)scatter graph
a) as age increases weight increases-its a positive correlation (1 mark)
b) 4 months (2 marks)
10) a)venn diagram (1 mark)
b)7/10 (2 marks)
11) simultaneous equations graph x=6 y=-2 (1 mark)
12) probability of losing = 62/72 = 31/36 ( 2 marks)
13) direct proportionality- y=80 (3 marks)
14) indices question
a) 4^-2 (2 marks)
b) this was 8^(5/3) - 9^(3/2) = 5 (2 marks)
15) 2 perpendicular line question k=3 (3 marks)
16)the sphere 10 square root 2 (4 marks)
17) make x the subject x= -3y-28/5y-8 (4 marks)
18) carrots -30p
Tomatoes -54p (4 marks)
19) dessert question - 7 (2 marks)
20) functions
a) (5x-2)^2 (2 marks)
b) 55 (3 marks)
21) circle theorem - 71° (4 marks)
22) plane/ cuboid question - 30 degrees (2 marks )
23) (10root3 + 27) / 39 (4 marks)
24) inequalities -2.5<x<4/3 (5 marks)

Here are some of the questions I have worked out
