Answer:
2 ways
Step-by-step explanation:
The best way to do this is to fix the position of the stranger and then arrange the two identical twins
The number of ways of knowing where the stranger will seat is 1! ways = 1 way
The number of ways of arranging the two identical twins is 2! ways = 2*1 = 2 ways
The number of sitting arrangements = 1 * 2 = 2 ways
Answer:

given data
Area= 3276 cm squared
lenght= 63cm
Required
The width
Step two:
We know that
Area= L*W

3276= 63*W
divide both sides by 63
W= 3276/63
W=52cm

Answer: Choice D</h3>
Explanation:
Start at the arrow tip. Move vertically until reaching the x axis. You'll arrive at x = 7 which is the x component of the vector.
Go back to the arrow tip. This time move horizontally until reaching the y axis, so you should arrive at y = -6
Therefore the vector is
which is in a column vector format. A row vector would have the numbers listed horizontally.
Put another way, the arrow tip is at the point location of (7,-6). This leads directly to the column vector mentioned in the previous paragraph.
