What do you mean by this question?
No people will be in Year 3 , 4 , and 5 because they can't study in 3 different years in the same time. LOL
The sum of pupils in Year 3 , Year 4, Year 5
= 128 + 146 + 122
= 396
\(sin15+85-9+22+3 = 101.258819\)
Just for further knowledge:
\(sin 15 = \frac{\sqrt{6}-\sqrt2}{4}\)
Your question doesn't make any sense.
Do you mean decimal part of pi?
But value of pi is infinite......
I will just give you an approximation of pi : pi = 3.1415926535897932384626433.........
P.S. LOL
0.2136 x 1/3
= 0.0712
And calculators are your best friends.
Maths bless you.
Don't be confused with that parentheses. They just means multiplication.
48÷2(9+3) = 48÷2x12 = 288
0.7^x=0.2
x log 0.7 = log 0.2
x = log 0.2 / log 0.7 ≈ 4.512338026
2696/6
= 1348/3
= 449 1/3
= sin2π/7 + 1/ sin2π/7
≈ 2.739
