Answer:
The answer to your question is 900 black and white copies
Step-by-step explanation:
Data
9 black and white copies for every 2 colored
printed 200 color copies
black and white copies = ?
Process
This is a proportion exercise
BW : C :: bw : c
9 : 2 :: bw : 200
bw = 200(9) / 2
bw = 1800 / 2
bw = 900 copies
Answer:
sin2θ - cos2θ = 2sin² θ
Step-by-step explanation:
hello :
tan θ = 1 means : sinθ /cosθ so : sinθ =cosθ
sin2θ = 2sin θ cosθ =2sin² θ
cos2θ = cos²θ - sin²θ = sin²θ - sin²θ =0
sin2θ - cos2θ = 2sin² θ

Step-by-step explanation:
Answer:
5 centimeters
Step-by-step explanation:
We know the equation to find volume is V = B x h, where B is the base of the prism. (It is also known as the simple V = l x w x h.)
No matter what equation you use, you will end up with V = l x w x h, since the base of a rectangular prism is length x width. So, we're going to plug in our known information to get 420 = 6 x 14 x h.
Then, we're going to multiply 6 x 14 to get 84. Now we have 420 = 84 x h. To isolate the h (in order to find what it is), we must divide both sides by 84.
420/84 = 5, so whats left of the equation is 5 = h, meaning your height is 5 centimeters.
:( sorry idk to this question
