99 and 59
X=big number
X-40 = small
X+ x-40 =158
2X -40=158
2X =198
X=99. Big number is 99
99-40 =59
99+59=158
In a full rotation, 360°, a point on the edge of a gear would travel a distance equal to its circumference. The circumference of a circle is:
C=2πr, and since we are only traveling 150°, we need to set up an appropriate ratio for circumference to the distance the point travels:
d/C=150/360
d=5C/12 and since C=2πr
d=10πr/12
d=5πr/12, and since r=4in
d=5*4π/12 in
d=20π/12 in
d=5π/3 in
d≈5.24 in (to nearest hundredth of an inch)

I can't understand this after "happening is" but let's do it unaided.
The number of ways to draw a boy first is 6.
Given that, the number of ways to draw a girl next is 10.
That's out of a total of 16 x 15 length two permutations of 16 things
![p = \dfrac{6 \times 10}{16(15)} = 1/4](https://tex.z-dn.net/?f=p%20%3D%20%5Cdfrac%7B6%20%5Ctimes%2010%7D%7B16%2815%29%7D%20%3D%201%2F4)
