There is no given data table but based on the question, the reaction is
xy <=> x + y
If we let M as the initial concentration of xy and c as the in the concentration after the dissociation, then we can use the ICE method
xy <=> x + y
I M
C -c c c
-----------------------------
E M-c c c
Solve for c using
Kc = c(c) / (M - c)
And the concentration of the xy, x, and y can then be determined
Answer:
28..
Step-by-step explanation:
divide 35 by 1 1/4...
Sine is positive while cotangent is negative. So this must mean cosine is negative since cos/sin = cot. In other words, cotangent is the ratio of cosine over sine.
Because cosine is negative and sine is positive, this places theta in quadrant 2
This is where x < 0 and y > 0. Recall that on the unit circle, x = cos(theta) and y = sin(theta).
The answer is choice B) quadrant II
complementary angles sum up to 90°.
so if one of them is 43°, then the other is just 90 - 43 = 47°.
Hello!
First of all, we subtract the popcorn cost, 12, from 40, giving us 32. Now we divide by 4 tickets.
32/4=8
Therefore, each ticket costed $8.
I hope this helps!
