Each mark in paper 1 is 0.625%
Each mark in paper 2 is 0.5%
Yah. So altogether add up to 100%
Prism...
Time needed to fill the prism: 2 minutes
Prism volume is half of cuboid. therefore total 3 units. So 6
divide by 3 = 2
Parallelogram
PQ = RS
Therefore find the length between P and Q
Then minus the x-coordinate of R to find x-coordinate of S.
y-coordinate is same as R
Midpoint of PR: (x coordinate of P+x coordinate of R) divide by 2,
(y coordinate of P+y coordinate of R)
Equation of QR: Find gradient (y/x), then use y=mx+c. sub value of
Q (x,y) into y=(gradient)x+c to find c (y-intersect).
Area: Height x length of PQ
