Lol, ATA ATA EVERY WHERE!! BIO KE LIYA PARH! MATH KO MAR GOLI

guyz n = 19 ?
angle op3 and op2 = 71.6
and about the pipe and liter speed around 5.6 ?
and raduis about 8.2 or some thing like that
MB= half AB or not?
puting in formua of square root a over b = root 10 over 3?
and can't rember anther just tell what u think.

our answers are very different,
n was actually 20
don't remember op3 and po2
pipe speed was 1744
radius of the cylinder was 87 (rounded to 1cm)
MB was not half AB, you had to use the trig ratios to find it, (SOH CAH TOA).
square root 10 over 3 correct.

ur ryt

 

[M.A.H]

The A* will probably be 173/200 max, knowing people worldwide did bad on paper 4...

 

[nyancat]

do u guys have the answers for p22?

 

[Yousef Khashaba]

Hey Guyzz...Abt the probability question hw was the last two answers?
and the last question the one about to find OP5 for 2 marks

Why is n=20??
360/18.4=19.5
18.4*20= 368
How coommmee it's 20??

Why is n=20??
360/18.4=19.5
18.4*20= 368
How coommmee it's 20??

this means that there can be 19 full triangles maximum.
so n-1=19

 

[abdulrhaman munther]

this means that there can be 19 full triangles maximum.
so n-1=19

Dude ... N-1 was on the left side .. N was on the right .. So N is the last vertix... Any thoughts about that my friend?

 

[omar gk]

paper was normal
if u knw the concepts very well then u will solve

 

[uzair shahid]

in the first triangle 1 was on the left side.
so in the 19 triangle 19 should be on the left side
therefore n-1=19

 

[omar gk]

n was equal to 20
rate of flow (speed) was : 1744 cm/min
the radius was 87 cm
this was the tricky questions in the paper

I didnt get it as 20 ... Please explain

 

[omar gk]

360/18.4 = 19. something
which means 19 triangles
the number of triangle is the n-1
so n-1=19
the n=19+1
so n =20

 

[Ozoman]

I didnt get it as 20 ... Please explain

360/18.4 = 19.55
therefore you will have a maximum of 19 triangles since you cant overlap.
triangle 1 was labeled from the first corner not the 2nd corner. (counting from an anti-clockwise direction)
which means that the last triangle, triangle 19 will also be labeled from the 1st not the second corner.
the first corner for triangle 19 was n-1

n-1 = 19
n=20

But n-1 was on the left hand side and n was on the right (

 

[uzair shahid]

dude if u see the first triangle 1 was on the left side
so in the 19th triangle 19 should be on the left
so the equation is n-1=19.
now get it?!

Just nevermind 3 marks down the drain and i left the last question totally empty as well as mensuration

 

[omar gk]

inshallah everyone will get A*
