So you don't have to use pi for this problem you can do L*W
So you can do 20*36
Answer:
w-9x/5=y
Step-by-step explanation:
It really isn't that hard. Don't let the other variables confuse you. First get everything else on one side. So, subtract 9x from w. You can't really do that, so you just leave it as w-9x.
Then you are left with w-9x=5y. This is like a 2-step equation. So divide 5 on both sides. Doing this leaves you with w-9x/5=y.
Thank you.
I’m gonna say it’s 168 because:
First u just do it as if the block has nothing missing so 10•8•3=240 and then u find the volume for the missing space which is 4•3•6=72
240-72=168 <= I think is the answer
Answer:
Between 9 and 20rows; at least of 9 rows
Step-by-step explanation:
Since there are eight seats in a row and in the auditorium we have about 70 to 150seats, the number of rows of seats that can fit into the auditorium will be between 70/8 and 150/8 rows which is equivalent to 8.75 and 19.75 rows in the auditorium. This is approximately 9 to 20 rows.
This shows that about 9 to 20 rows can fit into the auditorium.
The least possible number of rows means the lowest number of rows we can have in the auditorium which is 9rows according to the calculation above
COS(X+Y)COS(X-Y)
=(COSX*COSY-SINX*SINY)(COSX*COSY+SINX*SINY)
=(COSX*COSY)^2-(SINX*SINY)^2
=COS^2 X(1-SIN^2 Y)-(1-COS^2 X)SIN^2 Y
=COS^2 X -COS^2 X*SIN^2 Y-SIN^2 Y +COS^2 X SIN^2 Y
