Does anyone know the answer to the varnish questions
She didn't have enough, she had 7.5l but needed 10l to cover the floor which was 50m^2

No.

3/5 are female.
That means 2/5 must be male.
There are 36 male. Therefore the total number of teachers = 36/(2/5).
This is the same as 36*(5/2), which is 180/2 which is 90.
Yes, I was just going to the numbers that were given in the original post.

Yeah I ended up trying to use Pythagoras too xD
haha glad I wasn't the only one :P I just saw it was a right angled triangle so was like ik I'll find the side using pythagoras !

40% = 36

Therefore 100% = 36/40 * 100 = 90 people total

people who got 60 are wrong.
No 3/5 are female
36 are male

So 36/2*5= 90

It was a 5 mark question I think. I made that mistake too but when I checked, I changed my answer to the right one.
I made a stupid mistake on that one too but I reckon I can still get some marks for method
6. I think The envelops question (3 marks) was:
T=5x+20y

I think it was:
there are 3/5 male teachers
there are 36 males
How many teachers are there altogether.

So firstly you say 2/5 female teachers... i don't wanna go any further because i got 60 as my final answer whilst others got 90!
yeah basically you work out 1/5 of the teachers which was 18 and then you times it by five to get 90

Ah thats annoing, would I still get a mark for saying she doesnt have enough??
9. probability question and the question of 1/x2 inverse proportion
10. (Original post by coreHelp)
my friends got 75 pie but i had 4- pie so who is right?
75pi is incorrect.

4-pi is incorrect unless you're multiplying the whole thing by 25.

The answers are 100-25pi, or that simplified to 25(4-pi).

Thanks for this.
I ****ed up
Il **** you up
12. Also The answer for the question X^2 = 4(x-3)^2 was
x=6 or x=2
13. What was the answer for the two way table?
14. What did everyone get for x^2=(x+3)^2? (or something similar)
15. (Original post by Urbz)
would it still be right if you said 4%.
I suppose so yeah as it's the same probability

yeh

Yeah I think you would get the communication mark. You probably would get a method mark too but you wouldn't get the accuracy mark. That's how they mark it.

2 and 6

Does anyone know the answer to the varnish question.
It was She cannot cover the floor completely
Because the floor was 50 m^2 and she had varnish for 35.25m^2
She had 3 pots of 2.5litres each so 7.5 litres in total
Every litre could cover 5m^2 of floor
7.5x5= 35.25m^2
And her floor was 50m^2
20. (Original post by Lakshii)
how many marks was the last question ?
Was it 3 possibly?
