Twelve people join hands for a circle dance.In how many ways can they do this? Suppose six of these people are men, and the other six are women. In how many ways can they join hands for a circle dance, assuming they alternate in gender around the circle
Answer:
86400 ways
Step-by-step explanation:
Since the circle can be rotated, the number of ways to arrange a distinct number of n objects in a circle will be (n−1)!.
Now, if we rotate the circle with the six women, we will see that there are 5! ways with which they can be placed in the circle.
After picking the places for the women, we will now fill each gap between two women with a man.
We have 6 men. Thus, number of ways to arrange the men is 6!
Thus,number of ways they can join hands for a circle dance, assuming they alternate in gender around the circle = 5! × 6! = 86400 ways
Answer:
y=-2x+2
Step-by-step explanation:
the slope intercept form is y=mx+b
slope - to find the slope from 2 point you do (y2-y1)/(x2-x1) so it would be
(14-2)/(-6-0). which out simplify to -2.
y-intercept - the y-intercept is given in one of the points (0,2).
Answer:
B.
Step-by-step explanation:
We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.
The area of the original trapezoid is 36 square inches.
Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.
The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.
![1.5\times 1.5=2.25](https://tex.z-dn.net/?f=1.5%5Ctimes%201.5%3D2.25)
![\text{Area of new trapezoid}=2.25\times 36\text{ in}^2](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20new%20trapezoid%7D%3D2.25%5Ctimes%2036%5Ctext%7B%20in%7D%5E2)
![\text{Area of new trapezoid}=81\text{ in}^2](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20new%20trapezoid%7D%3D81%5Ctext%7B%20in%7D%5E2)
Therefore, the area of the enlarged trapezoid would be
and option B is the correct choice.
