No...read the er and u will get the idea...For scale a simple div of 2 per block is enough ...Plus it is advised to not draw more of the polygon than req coz ...look at er.
Abt my query..Do we have to constr perp bisector by compasses and also SHOW arcs or we can simply do it using protractor and ruler?

in rotation...
ii dont think so we have to show it as it is one mark question.....but its still very very much safer to construct prep bisector for accuracy...after doing so u can erase the lin...and i have nvr seen in an ms tht it asks to show it....

(a) look at the previous page at my answer
(b) divide 525 by 1500 and multiply by 100 to get the answer.

14 (a)
We'll subtract 30mins from the overall time 'cause she leaves work for half-an-hour. So, that'll leave us with the time of 3 45

We've to convert those 45mins in h. Therefore 45/60 = 0.75hours

Therefore:

3+ 0.75 = 3.75

Now:
7.60 x 3.75 = $28.5

Is the answer correct?

to get hours easily......see this way we will know how many hours it took to reach 1200...after which am would become pm...and thn simply add the hours 0430 in it...this way we will get full time......
