1. new to this so wasnt sure about the reply? was there an angle given with the last question as well as the two sides?

was an angle given with this question, as well as the two sides?
if you are refering to the last question- no

If you are talking about the last question, no there was no angle. You got the angle by rearranging the Area equation .

Area = ( absinC)/2Sin-1 C

= 18x2/(7x8)

= 40.00520088 degrees (DO NOT ROUND)

a^2 = b^2 + c^2 - 2 x b x c

= 27.20955764 cm (DO NOT ROUND)

Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

= 80.37550115= 80.4 degrees
4. thanks for clarification on q25.

when I realised 40 was the wrong angle I was using 108 insteead of 112 for 2ab so got the wrong answser (i got around 69 instead of 80) but got it now thanks.

How many marks would i get if i did round those answers. I still did everything else correct.
10. Highest grade boundary on a foundation paper was in November 2009 which was 156.

Hope this helps us...
11. Guys for Collins car question I forgot to add on the initial car park cost how many marks would I get I'm thinking maybe 3 due to having correct methods but lost 2 for the answer
12. Also for the rearranging the formula
It was y=5p^-x
Isn't it permissible to simplify to y=p-x÷5p because technically that is the same
13. What if I used 3.142 as pie?
14. For the trial and improvement, the answer is 3.7, because the value that 3.7 gives is closer to 35, cant remember the figure, but the figures are very close

Max 2 marks
16. I have a question. It's okay if I used 3.142 as pie for the last question? I got close to 80.4. I think I got 81.1 as my answer to 1dp. Would I still get some marks. ( I showed the working out)

I believe you would get Method Marks and lose out on the Accuracy Mark(s) hence lose only 1 (or maybe 2) marks if they are harsh.
18. i think i got around 100 what would that be
19. (Original post by smithj)
If you didn't work out the value with X=3.75 you won't get full marks even if you've chosen the correct answer
Thats exactly what i got, that is correct some people say 3.8 is answer which is incorrect

The paper usually says you can use 3.142 as pi.

Hence, you would get Method Marks and will lose out on the Accuracy Mark(s) if you still rounded in the middle of calculations.
