x^2-3x
3.
x=9.25
4. Smallest packet was best value for money because it was cheapest per bag of crisps
5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
0.4+0.15+4x+x=1
0.55+5x=1

The sector question
4. (Original post by Disfuligee)

The marks should have indicated there was more work to do. Never mind, hopefully everything else went well and Good Luck !!
Yeah i was thinking theres no way a 6 mark can be that easySilly me! Thanks again!
6. (Original post by Mahrez)
yes 7250 or something so it does
How'd you work it out? Scared to do my working on here incase I get roasted but here goes:

====
Paul buys a new car for \$(American computer, insert pounds)15,000

The magazine said new cars lose over half their value after 3 years. Is this true?

100-x% (X is the percentage depreciation after the first year, don't know value)

X% So X/100*15,000 = x* (asterik is for future notation)

100-x% (X is the percentage depreciation for the next years after the first, don't know value)

X% so X/100*x*(from previous answer) = 7392 <---- the answer I got.

Yes, the car lost over half its value as (15000/2 = 7500 so 7500-7392 = 108).

Is 45% OK for number 2?
Yeah it should be
8. i got £42.39 for question 11

i think u got number 19 and 20 wrong
9. I got 80.5 for the last question >.<

"i think u got number 19 and 20 wrong"

I got this as well, not sure if it is right or wrong but I got the same as Disfuligee

If I have the correct numbers,This is one way of doing last Q

Area = ( absinC)/2Sin-1 C

= 18x2/(7x8)= 40.00520088 degrees (DO NOT ROUND)

a^2 = b^2 + c^2 - 2 x b x c= 27.20955764 cm (DO NOT ROUND)

Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

= 80.37550115

= 80.4 degrees
11. I got that!
12. when you were feeling sweet that you were able to do the last question but you realise that the answer is 80.8 not 40.0 -_-
13. Is there one for foundation? Please give me a link if there is
14. Hey guys i reckon ive got 105 overall,will that be a B do you think?Need it to go into the army so just want my mind putting to rest if you can please

15000*0.77*0.82*0.82=7766.22

This is the correct answer so Paul is wrong
