We've to do this in every Q related to time?

i usually do this to change from day to night and vice versa..
for example in 2400 clock if ur time is bout 2030 and the time ends at 0450 thn minus 2030 from 2400 and simply add 0450.....

8hour45 mins? how did come across dis man this is where i face issue

7.45 a.m. to 12 p.m. is 4 hr 15 min.
12 pm. to 4.30 p.m. is 4 hr 30 min.
Total is 8 hr 45 min. Subtract 30 min as she stops work for this much time and you get 8 hr 15 min.
Multiply this by 7.6 and you get the total amount she gets: 62.7

Cool thnx

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....

so we erase the line later on ?
I am also talking abt in locus as well

i would show the bisector in locus...and its arcs.....but would erase the locus if the question states to draw inside a shape..but let the arcs show....in tranformation rotation just remove all arcs ......

and the line?..sorry for the bother but just need to clarify

 

[exploded diper]

i am not much sure bout tht myself.....but mostly the place to draw the tranformation gets very small so it gets messy and thn u would have to remove it ...i think i would erase it in transformation..

and definately in the locus if it says tht the locus should be inside a certain shape or region so...erase any line outside it as it is not needed....and do erase it........... but not the arcs
anything else just ask...however the ans would be in the morning at bout 6 .......

K I AM OFF..

If question states to draw using compass and ruler,we have to show our working i.e arcs.If they are too long, erase them partially but not fully.From examiner tips:
In construction questions, if you are told to use a ruler and compasses only, then evidence
that you have done so (construction arcs) are necessary to earn all the marks, for instance
when constructing a triangle given the length of all three sides.
Draw only inside the shape,other will be ignored.

But is the case for transformation arcs too? When finding center of rotation?
Because they never said Use compass to find it. .-.

In locus where they usually ask for 2 or more conditions,shud we draw a dotted/dashed line when for instance they ask us to shade the region of the point less or more than 5 cm from any pt..I mean do we draw a dotted arc coz dotted indicztes not part of and the boundary(arc line) is not included in the region

I don't think so, the shading itself is the recognition of possible positions..

 

[Dark Destination]

Do we have to extend the lines out of the triangle/quadrilateral when drawing locus?

Sometimes they say draw the locus INSIDE the quadrilateral, of points 3.5 cm from A, and stuff..

Since our arcs are outside, when drawing the perpendicular bisector, do we just join the arcs inside the quadrilateral, or do we join them from one arc to the other, even outside the shape given?

 

[Addi_gold]

yes its a v easy chapter dude.

Thankx

Do you really expect somebody to be awake at this time?

yes i we can extend it to outside

how much did u sleep? hows prep?

Good morning Gentlemen

Yeah Waliukum good morning
