    PAPER 1 OPINIONS glitteryhippie

    just wondering how everyone found it (higher)? the start was incredibly easy!

    any idea on the last part of the last q, about tide times in crookhaven? i got 180 for what c was, but any idea of the value of a and b?

    also what did ye say for the one about proving every answer to the equation was a multiple of 4??

      how did you get that, if you don't mind me asking? a lot of other people said that, but i have no idea how! i thought it was a simultaneous equation, but an unsure

      Though the questions are uneven marks. According to

      4/14 x 100, I got that you would lose approximately 29% if you didn't do them AT LEAST.

      I got 101,as multiplying by 10^2 was still 3 digits,and 100-2=98+3 was 101

      I said 100 for that question as they I assumed they moved it 100 decimal places, would I still get marks?

      David10

      No,you needed speed =distance over time=100 over 40=2.5 metres per second

      I'm talking about the 3.14 question

      Where did you get 100 (and 40?) from? I did 350 divided 80?

    16. avatar image

      David10

      From the start of line B to the end of point B is a distance of 100 metres, and the time it took was 40 seconds

      Yeah I did get that... I don't think where I got 350 and 80 from LOL. Probably because now that Maths is over, I'm losing me marbles.

      Did anyone get a=10 and b=-90 for q14?

      Its a symmetrical graph so at at 3 hours, it should be at zero.

      10(a)^2-90(a)+180

      10(3)^2-90(3)+180

      10(9)-270+180

      90-270+180

      -180+180=0

      Can someone correct where I went wrong please?

      Does anyone know when the marking scheme will go up?

    26. avatar image

      student331

      I'm not sure when they will be up but not any time soon because they may have to change the marking scheme for some questions.
