3D Trig: I got 59.5
Probability(Last Question): 25
Perimeter of Sector: 20.1
Volume of bottle: 600
Indices('b' section): n=x-2y
The triangle where Pythagoras and SOHCAHTOA was used: 2.21(Can't remember exactly)
Circle Theorems: 41
Equation of the Line: y=-2x-1
Domain excluded: 0.75
fg(x): (x-5)/(4x-23)
f inverse: 3x/(4x-1)
Gradient when x=-0.5: 7.3
Conversion: 0.0525m^2
Similar Triangles: 30
Completing the Square: 23-2(x+3)^2(Can't remember exactly)

I got 60 something for the 3D trig , I did tan angle times 13 over 5 root 2.
I got 41 for CT too.
Everything else looks like I got the same

same as you for everything else except 3d trig - kicking myself for it lol I forgot the formula for an isosceles triangle

Anybody remember their answers for the similarity questions ? Apparently there was a disguised conversion?

yeah - for part 1 i got 30 then the second part was like 0.0525 or something

Let's hope so

there will probably be range for the gradients
