Reply 3
the frustrum was 2/5h or h-3/5h

what was the last one about the line of symmetry I put 2x + 3y but couldn't get the c value
The value of c was 86. The total equation was 2x 3y =86
110 is wrong for the perimeter one; it was to 3 significant figures and the full answer was 110.5 so the answer is 111

No it was 110.49... so that rounds to 110

1.

(12.8 + (13.46-4.16))x5 =110.5

Was probability one something like 121/400

if you round your previous answers early you get 110.5 but if you keep all sig. fig. in your calculator you get 110

0s count as significant figures once they're within the number (e.g. 00067 is 2s.f. but 2304 is 4s.f) but either way the theory behind the question was solid so you can only drop one mark
