How do you remember all these?
I can only remember the hard questions!
-
These are copied from iTute i'm pretty sure, no way you could remember without the exam.
-
unless he copied his answers onto his formula sheet
-
How did you get 1.38 for the last graphs and relations question ?
-
Why would you write answers down when you could check :|
-
Whats the lowest average? How do u get that?

Find the first boundary by making the girl's equation equal the equation of the first part of the guy's hike plus 3.
Solve for t.
t = 1.625
Find the second boundary by making the girl's equation equal the equation of the second part of the guy's hike minus 3.
Solve for t.
t = 3
The time between those boundaries is the time that they are within 3km of each other.
3 - 1.625 = 1.375 ~= 1.38 hours

Yeah, I still don't get that 1.38 graphs and relation questions. It was the only thing I got wrong!!!!!!!!!

Big accusation mate :P Actually it was written down by my mate and I had exactly the same for all of them.
Also confirmed by going through the exam with my teacher.
-

Look at the stem and leaf and check the lowest number.
-
Was that it? Lmao ..... first question, zero marks.
-
Got a copy of the actual exam? Seems like you got some errors...

Nope, but do tell which things you think are errors.
These are confirmed by 2 people including my teacher.

How did you get $11.31 for that question in number patterns?
-
i think the solns are right, except for that maximum almond one where i got 120 >.> in graphs & relns

Wasn't the last question in number patterns asking for what value gives 200000 in march? I think you gave 3781, i thought it may be 2000?
-

I got 125g..
You had to find inequation x+y >(greater or equal) 500
then rearrange to find y so y=500-x
Sub this into the equation 0.2x+0.04y=40
0.2x+0.04(500-x)=40
x=125g

Sorry this one was confirmed by my teacher, I watched him do it.
Work out the value for t3 (march), then go 200000-t3.

Okayyy, damn
-
for the geo answer of 1.4m^2 , didnt it ask for the area of the octagon. so
.5*2*2*sin(45)=1.4 *8 gives you 11.something. did u forget to times the 8, or am i missing something here?

yeh i know i got it wrong, i did the same thing, but somehow got 120g

Nah just the triangle (OAB or something)
THen the next question you have to use PIr^2-area of octagon (which is 1.4*8)
