What did people get for the packet question?

Smallest packet was cheapest

will you still get marks for putting just 68 on the bmi question?

Second one is 0.65 ****ing ****

yeah i put that put cancelled out the (x-3) and the top 3-x would that be wrong?

You can't simplify further if u expand like that but you could of expanded like this

3-x/(3-x)(-3x-4) giving the same value on the bottom and then simplify by cancellation

Original post by samm98

In the ratio question I clearly worked out it was 4:3 and but because it said "in its simplest form" I put 1:0.75. Is that still right and if not anyone know how many marks I'll get for the workings?

Don't think you can have decimals in ratios so i would say wrong, sorry :frown:

Well looking from this mark scheme, my chance of an A* has gone. I'm confident I'll get an A though.

Original post by Jake Skelton

It was, yeah

I knew this is right.
Guys: 3-X is not the same as X-3 :colonhash:

:colonhash:

Original post by jasontoomorgan

yeah but that was the angle between 7 and 8, you had to then use the cosine rule to find out the other length and then the inverse cosine rule to find out x

(at least i think so, i got 80.4)

I used 1/2 a b Sin C, then i used the cosine rule then the sine rule. I got the same answer though.

No I'm certain it was 0.45 becase 9 people out of 20 got below 28
