Prime: 3,17,31
Composite: 10,24,38
Prime numbers can only be divided by one and itself, while composite numbers can be divided by a number other than one and itself.
44. You can come to this answer by using algebra,
1/2x = 22
Multiply both sides by 2(denominator) thus,
X = 44.
Or you can use lateral thinking and realise that if 22 is 50%, you need to multiply by 2 to reach 100%.
We have:

Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:

We clear f(x):

we simply what we can:

Thus, the correct answer is;
44 [minutes] * 8 [times as many as April] = 352 [minutes in April]
