Fair enough, I read the question and was like "WHAT THE HELL?"

Who else forgot how to work out percentage error? Lol

awww poor guy
i half forgot and then guessed... i got .4% i think.. or sumthin with 4 in it anyway

 

[xJaix]

oh ok. phew
well if 2 ppl got it and no1 else is commenting!
i cant remember how i got the 41.04 tho... i think i did heaps of weird trig stuff?
how did u get it?

I got it by doing arc length of a circle: 40over 360x2xpix15 = 10.47197551x4
= 41.88790205

I'm probably wrong

wat did evryone get for 28aiv), 26c and 26 aii and iii?
sorry!
but im rly stressing bout this damn exam!

28aiv) 56kg

26c) 20% chance of losing $22.50

26aii) 6/25

26aiii) No, Only 58% of critics liked it

Let me know and if you want to know how I did any of them.

I got 0.02. It was in a past paper so i did similar and got the same answer as i did for the percentage error in the previous paper! it worked

thats what i did. and felt full genius when i did it lol. because like it had a circule thing, and it was cut from a cylinder, making it circular?

Yeah the arc length would have shown how long all the 4 pieces of cheese bases would be if you straightened them out. We needed to find the size of the box though, which was in this case the length directly from corner to corner of the cheese slices

oooh ur making me feel better about this paper!!
i got all of those except i left 28 as a decimal or 55. sumthin
and lol to 26c!! i followed no logical procedure and still got that


thanks heaps!!!!

 

[r0kstar]

sorry!
just one more question.. i swear
was the answer to 25 a ii) 8yrs?
thanks!

Yeah with 28 I rounded to the nearest Kg

Yeah that's the key to general maths, sometimes you just need to think logically about a question and you get it alright. I did similar with 26c, I don't even know if their is a set procedure for it?

What did you put for 28av2) and also 25b) ?

These are the only 2 I am not sure about in my paper
Everything else I have double checked and seems to be right

 

[r0kstar]

yep

thanks!

 

[serks]

hay i was just wondering if it was acceptable to write using a pacer ?
i only realised it said write in blue or black pen with half anh our to go

takes 9 hours to get to borneo. Borneo is 5 hours ahead of Kenya

if the plane leaves at 10 pm (TUESDAY) add 5 hours just so that you don't confuse yourself to convert the departure time into Borneo time.

10+5 = 3 am (WEDNESDAY)

3 am (departure from Kenya Borneo time) + 9 hour flight = 12 pm Wednesday.

 

[lil-monkey]

it took me a while to cotton on to the cheese question but i think my working out i may have solved it ( in the beginning i wrote "how to you fid the side length of the cheese?" on my paper)
but after all the time a wasted i wanted to make on the time on the volume q and promptly forgot to times the area of the triangle by the width.... bugger :mad1:

i thought the cheese q was easy,( the box dimentions etc) but i just hope i did it correctly lol.
but for some reason in the volume q i also forgot to times by the width IDIOT!!!.
oh well maths is finally over i hope i get a good mark though or....

Your almost correct, the flight time was 9 hours so they do arrive at 7am Wednesday from the place they depart from (Kenya) but it asks "what will be the local time in Borneo when the aircraft arrives?"

75 Degrees difference

1degree = 4mins time difference

75 x 4 = 300 minutes

300/60 = 5 hours

Therefor you need to add 5 hours onto the 7am Wednesday to get 12pm

oh ok sweet
umm for the reason one i put like sum crap about how thrs too much variation in thr heights as they get older as sum stay short and sum grow way taller wat did u put?
25b i think i put 73/145... from memory wat did u get?
if u want u can add me on msn dw_727@hotmail.com im sick of bos
