Did people get x=144 for the polygon question?
I did! Is that right then?

bars in trolley question
work out volume of shape- area of cross section x length
76 x 120
=9120cm^3

mass = density x volume
8 x 9120
=72960g
=72.96kg

250/72.96
=3.4265......
=3
**** i thought it was 72960 kg which is why i couldn't answer it. how many marks will i get? i got up the weight part

The grade boundaries varies with each year, smartass.
But just use last years for an estimate, silly goose
8. did pepole get 4:3 for the ratio
9. (Original post by Aleiya)
80.1 is also correct. It seems 80.3 or 80.1 is the answer
seriously i got 80.9
10. Did anyone get 5.5 for the estimate of the mean
11. What did you guys get for the question on the guy travelling to work?
12. polygon question

exterior angle of pentagon =360/5 =72
therefore interior = 180-72 = 108
interior angle is split in 2 =54
triangle in parallel lines has a right angle- 54+90=144
so other angle =36
360 - 36 - 36 =288
288/2 = 144
1. Order numbers correctly and include a key

3.8 was the answer because if you try 3.75, the result is too small, meaning the solution is closer to 3.8.
18. Pretty sure the answer is 80.4, not saying I got that though
19. (Original post by Ihateexams16)
Did anyone get three for the amount of bars you can fit onto the shopping trolley question???
Yeah I did
20. Any predictions for the grade boundaries?
