Mathematics: Post your doubts here!

[Mai(M4!)]

should i know these:
quadrelateral family tree
rate of flow
percentage of error
denisty
scales
???????????
cause i didn't find them in the syllabus

 

[Mai(M4!)]

for 9th one u subtract it by 0.5
(as 1/2 = 0.5)
so its 200-0.5 =199.5
rest is correct

right how stupid of me to forget such a point
thanks

s=side
s2=37.8225
s=square root of 37.8225
s=6.15
0.1/2=0.05
6.15-0.05=6.1
