X= (k+c):(m- ny/b)=(k+c): (mb-ny)/b= (k+c)*b/(mb-ny)
x= (bc+bk)/bm-ny
D is correct
Answer:
I believe its a trapezoid. Sorry if I'm wrong.
Step-by-step explanation:
Answer:
∠A = 45°
Step-by-step explanation:
It is given that,
sin A = sin B
∠C is a right angle.
If sin A = sin B, it means
sin 45 = sin 45 =
It means that angle A and angle B is 45 degrees.
Answer:
(a) Number of committees formed if there are no restrictions = 350
(b) Number of committees formed if 2 of the women refuse to serve together = 310
Step-by-step explanation:
As per the question,
Number of women = 7
Number of men = 5
The different committees are possible if
(a) There are no restrictions
Number of committees formed
=
= 350
(b) 2 of the women refuse to serve together
From the 350, we must subtract the number of ways those two women serve together.
If the men and women both serve together, then 1 woman serve with 4 men.
The men are chosen
,
So
The number we must subtract from the 350 is 4 × 10 = 40
∴ Number of committees formed = 350 - 40 = 310.
