[Modar]

Could someone explain how the lines OB and CD are parallel in Q7 of Paper 4? I checked the lines with a ruler and they were NOT parallel..

they said not to scale so it doesnt have to be parallel

 

[chhayank]

id ;[email protected] and thanks for maths paper.......

they said not to scale so it doesnt have to be parallel

If they asked us to define the relationship between the 2 lines, then they would make it accurate. When it says 'not to scale', it means that the angles and lengths are not equal in theory to the ones printed. But parallel lines must look like they are parallel. We use calculations to work out every angle and side asked, so you cannot simply put in 'parallel' because it's one above the other.

What're you getting for paper 2 question 12 a)?? I'm getting 10 while the answer given is 17.3

10 is correct answer.

15 km is correct answer

[aliiiiiiiiii]

dude your teacher is wack

yeppp

 

[Mrigendra]

how is that correct to 2 significant figures? -_-
Btw how did your teacher get the papers? o.o

It should be 64000

 

[Mrigendra]

I think in the trigonometry question the letter 'o' has two lines of symmetry as it is not a perfect circle

'O' or 'o' can be considered as a perfect circle. Anyways in the question it looks like perfect circle.

[Ahmed Alaa El-shamy]

First of all thank you so so much for uploading this
second of all still this paper is not realiable as there are so many incorrect answers written and i guess most of us agree about that so anyone who calcluates his score it won't be exact ( but it will be just near too which is good at least u know around how much u are going to score)
but as i said before i really appriciate your effort in doing this
and for those who got chemistry good luck and lets hope for the best and who don't take at least remeber us in ur prayers

PEACE
