How do you remember all these?
I can only remember the hard questions!

[Maths1234]

These are copied from iTute i'm pretty sure, no way you could remember without the exam.

[thushan]

unless he copied his answers onto his formula sheet

[123david321]

How did you get 1.38 for the last graphs and relations question ?

[Maths1234]

Why would you write answers down when you could check :|

[seretide]

Whats the lowest average? How do u get that?

How did you get 1.38 for the last graphs and relations question ?

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

[Haras_Etak]

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

Big accusation mate 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.

[seretide]

Was that it? Lmao ..... first question, zero marks.

[Namit]

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?
