# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme Watch

1. (Original post by junayd1998)
How bout the construction Qs how did you do them
you were supposed to draw the line y=4 then see where they intersect, but i instead moved the entire graph down by 4 then measured where it intersected y=0

do you think that will still be correct
2. who thinks maths is cool
3. (Original post by Gamer_44)
Yes I got this The constant = 100 didn't it?
Yessss
4. whats q5 again?
5. what were the marks for each question??
6. How was the higher paper?
I will be interested to know from students on high B, hoping to perhaps get an A

idk what your tallking about. Im talking about the ones where you had to take out the compass and draw the lines and ****

Pretty easy, going to be high grade boundaries.
9. I got the 4=(X+3)^2 or whatever it was question wrong, but I expanded them properly and all that stuff it's just my factorisation and answer that was wrong how many marks will I get?

My maths teacher predicts a harder calculator paper to follow...wasn't to bad though, I I got reckon 62-70 marks

Depends on how many marks, presuming it was ~4, You'd probably get 2/4
15. It was a right angled triangle with the sides attaching to the right angle both being 'square root 2' / 2. Then a shaded portion inside the right angles triangle making a thin triangle on the hypotenuse if that makes sense. The length of the side minus the base of the shaded triangle was 'square root 3' /3. Then it asked for the exact area of the shaded triangle.
16. does anyone remember the marks for each question?
think I lost more than 20marks

Not necessarily

Hey, if anybody is willing to contribute the answers, and preferably the questions, then I shall set up a mark scheme for you all. Thanks in advance!

Can people please attach question numbers to their answers? Method would be appreciated.

This will be updated as I go along.
Spoiler:

Question 1. What is the volume of the prism? (2 marks)

Area of face = 30cm²
Length of prism = 25cm.

30cm² x 25cm = 750cm³

Question 3. What is wrong with the questionnaire? Give two reasons. (2 marks)
Attachment 538813
'Too vague (i.e. not 1-2, 3-4 etc.)' and 'no time frame (i.e. not per week, per month, etc.)' are accepted.

Question 4.
P2 x P5 = P7

G6 ÷ G4 = G2

(K3)2 = K6

Question 5(?). Estimate 892 ÷ 18.9 (2 marks)
Round to 1 significant figure

900 ÷ 20 = 45

Question 6. A teacher is picked at random. 3/5 chance they are female. 36 are males. (3 marks)
How many teachers are there altogether?

2/5 of teachers are male. 36 are male.

2/5 of total = 36
2 x 18 = 36
18 x 2 = 90.

Question (?). Solve X² = 4(X-3)²

X² = 4[(X - 3)(X - 3)]
X² = 4[X² - 3X - 3X+ 9]
X² = 4[X² - 6X + 9]
X² = 4X² - 24X + 36

0 = 4X² - X² - 24X + 36
0 = 3X² - 24X + 36

0 = 3[X² - 8x + 12]
0 = 3[(X - 6)(X - 2)]

X = 6 or X = 2

Question 11(?). What percent of his total spending is his rent now?

Question 13(?). How many females visited the art gallery?
66 students went on the trip.

Males - Bowling - 4
Females - Bowling - 6
Total - Bowling - 10

Males - Art Gallery - 9
Females - Art Gallery - 11
Total - Art Gallery - 20

Males - Skating - 10
Females - Skating - 26
Total - Skating - 36

Males - Total - 23
Females - Total - 43
People - Total - 66

Question 14(?).
Attachment 538769
Area of square = 10cm x 10cm = 100 cm²
Area of circle = π5² = 25π cm²
Area of shaded = Area of square - Area of circle = 100 cm² - 25π cm² = 100 - 25π cm²

Question 15(?).

200 x 25% = 50
200 - 50 = 150

Question 21(?). What is the chance of the match being cancelled when it does not rain?
Attachment 538811
0.8 x 0.05

Question 22(?). What is the angle?

Angles in a triangle add up to 180°, base angles in an isosceles are equal.
180° - 48° - 48° = 84°

Angle at centre is twice angle at circumference.
84° ÷ 2 = 42°

Angles in a triangle add up to 180°, base angles in an isosceles are equal.
(180° - 42°) ÷ 2 = 69°

Question 24(?).
Table - 100, 25, 4 (?)

Question 25.
Attachment 538759

(3-√6) ÷ 12
You know question 14 - the one that was 100-25π - the question said leave your answer in its simplest form. I'm just wondering, were we supposed to put 25(4-π) ? Or is it "simpler" to put 100-25π ?
19. Is it for question3 if i answered, some people may interpret answers as being different from others and some people may never eat crips.
20. Area of prism 750 🙌🏻🙌🏻🙌🏻🙌🏻
