isn,t the MS incorrect on q16 abt the length of ribbon on cake(similar question)
Also guys tell me if there is a fraction like 1/5 we can simply write 0.2 but the MS at times show 1/5 as the only answer...Check the matrix question for this reference last question..I dont know wht oe or other symbols mean in MS exactly so if any enumerate the symbols with the expl i will be glad...And also to further complement my pt abv in the acceleration quesstion which is 5/4 they write 1.25 as only answer

oe means or equivalent.

And the stupid marking scheme is wrong. Your answer is right!

There u go.......

I know that the answer is 4o but it doesnt make sense as its almost of the same size as the diagnal .

Bro , the answer in the marking scheme is wrong

Such a grudge against the MS...
Anyways how r u getting along with maths?
Can u explain wht some other symbols in MS mean like A B C and any other?

Maths. It's just normal. Planning to start practicing papers from tomorrow, properly. Did only 2 today. .-.
Oe = or equivalent.

A1, M1 are mostly used in physics, chem. Not here.
Here, it's just OE.

Aha ...and also check the MS for the abv question paper regarding the matrix question they ask to write B inverse but they left the matrix(in their answer) in incomplete form .Further,ore the answer space shows tht qw have to write final matrix without any scalar multiple beside it..So shud they not mention oe there and also tht they have to be more specific and there has to be a bit more calculation?

It's okay both ways. I never multiply it into the matrix, always leave the fraction next to it.

Write them as separate fractions
9*2^12/3*2^8 -3*2^10/3*2^8
=3*2^4 -2^2
=3*16 -4
=44

[Bilal Kamal]

sorry mate i cant get it from ur working , can you solve it on a piece of paper if possible

just take a snapshot ..... or press the link and click select all and then copy

I know that the answer is 4o but it doesnt make sense as its almost of the same size as the diagnal .

no only "l" is 40 but the whole vertical length is underoot 40

If you call this shit a trapezium, then okay

OoooOoOoOoOOoOOO k got it thx

 

[Sam Shaikh]

Can someone please help me with shear and stretch? Especially the part relating how to get the centre point in both.

Salam everyone!
I did not prepare for Mathematics GCSE, And I have an exam day after tomorrow. I do not have any concern for Grades, Please! Tell me what should I practice in these 2 days for Mathematics paper 1 and What to study in rest 2 days gap for paper 2?
