80-85 based on 1 papaer

No. Was 100-25pi simplifies to 25(4-pi).
my friends got 75 pie but i had 4- pie so who is right?

How many marks was circle theorem 3 or 4

Posted from TSR Mobile
5 marks
4. [QUOTE=LogicalFallacy;65190495]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.Any ideas for the finding estimates for the graph one? There were 2 equations and then the simultaneous one I think..
5. 3. I spent about 20 minutes on it x'D

I said 75pie as final answer but that is wrong i think because it is not 100pie - 25pie
7. (Original post by Blueee29)
fml got the right answer at first as 100- 25pi but then decided it was wrong and crossed it out and put 100- 10 pi.. Sucks, I'm normally an A* student and pretty sure i barely got an A
Is that its simplest form? I do hope so
8. X^2=4 (x-3)^2 solutions were 2 and 6 by creating a quadratic and either solving or factorising.

First one was 750 cm^3

90teachers

36% on rent

150 students over £130

100cm^2 -25 pi (I factorised to 25 (4-pi) ) for the square with circle in it

she does not have enough varnish, she needs 4 tins and only has 3

As much as I can remember so far, will update as I remember hope all went well for you guys

Q1 750cm^3
Q2 too vague and no timeframe
The class is a small sample/biased
Q3 p^7
g^2
k^6
10-5m
n(n-7)
45
90
No not enough varnish cos she needs 50cm^2 but has 37.5cm^2
60
T=5x+20y
(-3,-2)
11 females
100-25pi
36%
I compared median, IQR and range
150
7x10^8
X<7
7/5
2 4/5 in mixed fraction form
4/5
x=-0.4 and 4.4
X=-1.1 and 5.1
X=-1.7 and 4.7
Angle MST 69
Probability is 0.04
X=2&6
a+b
-a+3b
3/4(a+b) for vector
Point s is on both lines and it is point where they intersect
100,25,4
Final questions is (3-root6)/12
What was the question that had 60 as the answer? Dw if you cant rememeber i was jw
10. what do you think the grade boundary for an A will be, apparently loads of people are complaining on twitter saying it was hard, what do you think?
Harder than last years or on par?

was this all of the questions??? I got 31 / 36 here
12. Can't remember the question, I think it was solving simultaneous equations on graphs: for the first part I completed the square and got the solutions because I honestly was stuck.

I said 75pie as final answer but that is wrong i think because it is not 100pie - 25pie
I typed this answer on google and I'm seeing a yahoo answer diccussi g this question from 2009 what even the questions were really similar to questions I've done before so that was good
14. (Original post by ewales)
That was a tricky one, everyone at school seems to have different answers:
Mine being (2 - root 6)/12.
I think (could be wrong here) that mine was 1 and 30/36. (As in, all one mixed number.) I'm really not convinced it's right though.
15. number 4 p^7, g^2, k^6 -5m+10 n(n+7) ( 6 marks)
number 5 is 45 (2 marks
number 6 is 90 ( 3 marks)
number 7 is no ( 5 marks)
number 8 is 64
number 9 is T=5x =20y ( 3 marks
Number 10 ia 3,4.75 ( 3 marks)
number 12 I got as 75 (3 marks i think)
number 16a i got 186 (2 marks)
number 17a I got x<7 b. w=4 (4 marks)
number 18a is a mixed fraction 4 1/3 b. 32/15 (6 marks)
20. I got 116 degrees (5 marks)
22. is x= 4/12 x=-4/12 I am certain about that did question similar to it before exam and it follows same pattern (4 marks
thats all I got
16. (Original post by gcseexamz)
43 were female i think
Lol u got it wrong it was 11 it was a two way table.

17. 100-pi is wrong, it should be 25-pi coz they tell you to simplify
18. (Original post by GCSElyfe)
1. 30x25 = 750cm3

100-25TT

G2

P2 x p5

(K3)2

Didn't have enough litres

Solve X2 = 4(x-3)2 =3?

36%

0.04 probability

90 teachers

Table = 100,25,4

Idk whether these are right
swear it waqs 0.8x0.05

no it was 3/12-root6/12

No that's the probability that it wasn't going to rain AND it get's cancelled, or the other way around. It was 0.8*0.95 though.
