Decimal 30 = binary 11110. The decimal binary code (BCD), however, is 11 0000.
14 decimal in binary is 11102. In octal it is 168 and in hexadecimal it is 0E16.
That depends what you mean by "B", and what you mean by "binary code" assuming that by "binary code", you actually mean a binary representation of it's ascii value, then the answer is 1000010. The ascii value of the character "B" is 66 in decimal, which is 1000010 is that value in binary. If on the other hand, you mean "what is the binary value of the hexidecimal number B?", then the answer is 1011.

Lowercase z is 122 decimal, 7a hex and 1111010 binary.
In hexadecimal, that would be 0x2E, which is equivalent to 46 in decimal, which in binary is 101110.
