Flag format: poctf{...}

An easy level challenge... How about a couple simple little logic puzzles? Here are twelve problems. Their solutions should all be in hexadecimal format. I'm sure you know what to do from there, right? Good!

  1. 0x67, 0x70, 0x73, 0x76, ___

  2. 48 = ___

  3. 80, 85, 96, 101, 112, ___

  4. Let f(x) = 2x^2 + 3x - 5 and g(x) = (x + 4) / (x + 5) and solve for: f(g(20)) + 10 * ((e^3 - 20) / 3) + 95 = ___ Where: e is 2.718.

  5. 0x64 + 15 = ___

  6. 41, 0x38, 69, 0x50, 89, 0x60, 101, ___

  7. f(x)=(x*2)+10 x=___ where f=114

  8. 1, 17, 33, ___

  9. Asset Value = $50,000, Exposure Factor = 60%, ARO = 0.0036667, ALE = ___

  10. 17, 19, 23, 29, 31, ___

  11. min(max(0.3100+0.350+10,0.1150+1.050+47))

  12. MTTC = {40, 28, 35, 42, 30}

NOTE: The solution will produce the flag in the form of an English quote or phrase using the alphabet in the rules for flags. If your solution produces a choice of characters, the correct answer is the one that is part of the character set, or completes the proper phrase.
