Anyone????

I

Is the perimeter correct?Did you also get 118?

No just post that.

Yup

i saw a girl attempt her paper in/under 1 hour and was begging the super visor to let her go,was she intelligent or had left the paper ? cause i was still on the last question at 1055 slow me couldnt even recheck

If the preson,s a girl then she had a bad ppr
Just kidding.I think after discussion u wud have known tht ppr was not tht easy infact standard difficulty for me

 

[asadalam]

Yup

Thank god,i was thinking that i got that wrong.Lengths were 25 and 35 then?I thought they were 15 and 35.Maybe i forgot.

circle was pretty easy like all the paper
1 mark down in that percentage profit one

All else perfect?

Was it 180 euros and 500 dollars (that we had to convert - I am asking the question here - not teh answer)

Yeah

Yes
180x1.25=225
500/1.25=400

apparently

Wht abt the timetable question and inequalities wht did u get as inequalities

 

[M.Omar]

1103
x>1
2y>x+2

wht abt is equal to sign?
x=>1 same for y ?

Anyone????View attachment 43946

outside p =1020 cm which gives 2(4x +5y)=1080
and for total perimeter
2(6x+3y) +2(4x+y)=1360
U can simplify further

In last q,smallest angle was D65 and x was 20 y was 35?

 

[asadalam]

Yes.

in that quadratic equation answers were 2 and -5 right

 

[Awesome12]

It was 5,and yes 0.8 was involved i think.We had to use 0.8 instead of 1,since 0.8 is also correct to 1 sig fig

We did not have to use midpoints

 

[Abdul Hanan]

is it okay if i started boys polygon from origin?

 

[muhammadali233]

now i kill myself and die in piece *yay*

In polygons?We have to use midpoints...

What was estimation... I got 6: 42/ 10*0.7

 

[muhammadali233]

wrong

 

[asadalam]

What was estimation... I got 6: 42/ 10*0.7

It was 5,42 is not 1 sig fig and we had to use 0.8

Look at the s08 paper and ms,they are points in which x axis points are midpoints....It was of one mark at least.
