(seem to have trouble at the end)
Hey, hope this helps:
step 1) write in terms of ratios-
1km:1000m (cross multiply) 10712: x now we know x= 10712000m
Step 2) again use ratios -
1litre:59m x :10712000(use your answer previously calculated) now we know x=181559.3
*Mentioned in the question to write in standard form, so you write this answer in standard form*
Final answer:1.82 x10^-5
"^" means raised to the power of -5 hope this helped out oh and next time please mention the year and paper 2 when you ask a question :") best of luck
Don't worry about it mate, my teacher isn't that great either. I've found the best way to score good grades in math by practicing. i'd say you practice several years starting (2010-2015) btw where are you giving the exam? (country) that will decide which variant you must focus on (although there isn't much of a big difference)

Hey hafsa i live in Oman administration zone 4 i was taking edexcel last year and moved to CIE. Despite the fact i have a bad teacher he gave us all the papers of 2013-2015(paper 4).I haven't covered exactly everything i need. I've done all of the 2013 papers(paper 4) but not in exam condition.Yesterday i did my first exam condition one and i got a B :/ i want a minimum of A in maths and i really feel concerned now
the 2010 papers i beileve are out of date of the current syllabus as they removed shears,stretches & sine & cosine graphs
You're absolutely right, but you see we rarely come across those questions i guess once every now and then but i don't think it should stop us from practicing those years. Alhamdullilah, i've seen myself improve by the load of practice

Hey, don't let the grades upset you I got a B In my mocks as well, because we weren't prepared enough. Also, we get graded for our working so even if you miss a little here and there you can still score marks... Worrying will get you no where bruv, chill and give it your best. Practice as much as possible and leave on God the rest
I do really bad at circle theorems its my weakness at maths and also vector geometry
I was horrible at the circle theorems, but like i mentioned earlier i sort of improved...i owe it to the hours of practice. I'd recommend you practice three variants a day and don't forget to time yourself

I think it would be best of you check with your friends or your teacher about the variant, because i actually have no clue. sorry as far as i know, i'll be giving variant 2 but i don't live in Oman
