lol

The only maths chicks need to be able to do is ratios...so they can change the amount of ingredients needed for the recipes depending on the servings

^^lolololol, dont forget working out the area of a sandwich

Expand LHS, you eventually get something in the numerator including p+q-r and other positive terms

 

[khorne]

what about the inequality in question 5(b) ?

I am such a cunt. I assumed it was true, worked to a point that it was true, then crossed it out and rewrote everything backwards

hey man, they have to be able to push digits on microwaves too

s0rry I forgot about this...

If 100g of pasta needs 1 min on high, how many minutes does it take to microwave 150g of pasta on medium?

i did that at the start as well. but i cbb to continue since it's question 5. so moved on with other questions.

answer: trial and error until it feels hottish

correct

Theres a really neat way to do it if you start by observing that x/(1+x) = 1 - 1/(1+x) and 1/(1+r) ≥ 1/(1+p+q+pq) = 1/(1+p)(1+q): the equation then factorises into positive things

lol'd but clearly fake, most of those girls are butt ugly

poast solution pls

people saying 90/120 cut off for e4 are fucking scaring me....

If last year 79/120 (66%) ->92 then i doubt the cut off this year will be 75% considering the paper this year wasn't that much easier in comparison ....

i think last years cut off was like 72 or so, so this years will be around 70

This works:

Nice, doubt many people would have saw that neat trick though :S

For me I just thought of expanding it and see what I get

Same here, I expanded the left hand side, then I got a conclusion that p + q + 2pq was greater or less than zero, then I wrote backwards from there on the actual answer page.

i got owned, thought i was doing mad then got owned after q3
Hoping for a 85+

its a straight line x = -1/2. then you shade in the area closer to x = -1. i fink not sure tho.

Lol, i was trying to change it into a+iy form, coudn't finish though
