$75\sqrt{2}(\sqrt{3}-1)$

Step-by-step explanation:

In every right triangle, a leg is given by the multiplication of the sine of its opposite angle and the hypothenuse.

In this case, the opposite angle of x is 15°, and the hypothenuse is 300. So, we have

$x = 300\sin(15) = 75\sqrt{2}(\sqrt{3}-1)$

Answer: a) 2092278989 b) 576, c) $\dfrac{576}{2092278989}$

Step-by-step explanation:

Since we have given that

Number of students = 16

Number of desks = 16

a) How many days must pass before the class must repeat a seating arrangement?

$16!=2092278989$

If the number of rows = 4

b) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?

$4!\times 4!\\\\=24\times 24\\\\=576$

c) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?

$\dfrac{576}{2092278989}$

Hence, a) 2092278989 b) 576, c) $\dfrac{576}{2092278989}$
