Now maybe?


Done.
there was a volume question asking to find the volume
it had 2 more other shapes at the top
but i just did 9*7 = 72 and then *10 = 720
or whatever the numbers were and it was a rectangle i think..

mr m would i get it right, and are u an examiner

Mr M, for question I gave the answer as 620 as I left it as 31 instead of 30, will I get the marks?


Yes.
Mr M, this isn't about edexcel but a GCSE AQA question...

We had a 2 mark questionnaire which just required a response question, and I did 5 response (tick boxes), non overlapping times (but didn't start from 0/I used minutes when it was supposed to be days) and displayed it as n-n, not with inequalities.

I know edexcel is different from AQA, but from your knowledge, do you know how many marks I'd get, if any at all out of 2?

1 mark for that.

I am an A Level examiner and I write exam questions (not for GCSE though).

Probably 1 out of 2.

for the question about about fillling his garden with seed was it asking for the price or how many bags he needs? i put the price does this cost me any marks?
Mr M for question 12 I did all the working out but my final answer was 36-8.5pi, will i get the full three marks.
Yes :smile:
According to this - if i get all the qwc marks and stuff then i will get 98. Woo Hoo!
The question I got wrong was 14 on bearings I put 310. Do you think they might make it an SC and give one mark for it. I hope they do - I was going for full marks because my sister got 200/200 when she did it a couple of years ago

I'm afraid not as your answer is wrong. You might get two marks though.

Done.


I wasn't referring to that question, I was referring to the question about the 12 sides.

So you were. Sorry. You don't need a diagram for that question.

Two interior angles of the regular polygon + one interior angle of an equilateral triangle = 360 degrees.

This is all you need to know.

310 *might* get one mark but I'm not convinced.

It asked for the price.

It's just that I wrote the answer as 6. But I probably had 12 somewhere in my working. I worked out the in the triangle and I subtracted that to find the interior of the polygon which was 120 and then I worked out the sides by n-2 etc.

How many marks would I get ?

Probably 2 marks. The interior angle of the polygon was 150 by the way.

I still don't understand how it's 150. That's why I wanted to see the diagram.

For 27b i got the shape of the cosine graph correct but i don't think it went through the correct angles. Will i at least get 1 mark.

Perhaps you could read my previous post?

Two angles of the regular polygon plus one angle of the equilateral triangle met at a point.

If the shape was sinusoidal then yes I think so.
