    What's grade boundaries like for AQA?
    How many marks for a C and B for example?

    Best of luck.
    C was 55/175 B was 85/175 A 117/175 A* 145/175

    For the question asking you to find an equation for a line passing through a point (question 13?) I think I may have got 3x-4y=19

    16. Volume of the vase was 102 cm3.
    Working out:ASF = 120/750 = 0.16
    LSF = ASF square rooted, = square root of 0.16 = 0.4.
    VSF = LSF cubed, = 0.064Therefore volume = 0.064*1600 = 102.4 cm3
    =102 cm3 (3 s.f.)

    I agree, could you please explain how you and your friends got that answer?
    I split it into three triangles and worked out each area seperately.

    1. Split the pentagon up into a big isosceles and two equal scalene triangles.
    2. You use 1/2absinC to get the area of the 2 scalene triangles.
    3. Split the isosceles triangle into 2 right-angled ones.
    4. Use cosine rule to find the hypotenuse of the right-angled triangles (same as the longest length of the scalene triangles)
    5. Use Pythagoras to work out the height of the isosceles triangle.
    6. Use 1/2xBxH to get the area of the isosceles, and add on the areas of the two scalene triangles you got at the beginning, to get 188.

    Yeah you do that but for the top two right angle triangles you need to use the sine rule.
