Part 1
1.) 1011= 2^3 + 2^1 + 2^0 = 8 + 2+ 1 = 11
2.) 101010= 2^5 + 2^3 + 2^1 = 32+8+2 = 42
3.) 11111= 2^4 + 2^3 + 2^2 + 2^1 + 2^0 = 16 + 8 + 4 + 2 + 1 = 31
4.) 10010 = 2^4 + 2^1 = 18
Part 2
1.) 31 = 2^4 + 2^3 + 2^2 + 2^1 + 2^0 = 11111
2.) 51 = 2^5 + 2^4 + 2^1 + 2^0 = 110011
3.) 7 = 2^2 + 2^1 + 2^0 = 111
4.) 103 = 2^6 + 2^5 + 2^2 + 2^1 +2^0 = 1100111
Part 3
1.) 56 Kbits/sec = 56/8 kbytes/sec = 7 kbytes/sec
7 kbytes/sec = (1/7) sec/kbyte
100 mb= 102400 kb
102400 kby * (1/7) kby/sec = 14,628 sec = 237 min = 3.95 hrs
2.) 5 mbits/sec = (5/8) mbytes/sec = 8/5 sec/mbyte
(8/5) sec/mb * 100 mb = 160 seconds = 2 min 40 sec
3.) 10 mbits/sec = (10/8) mbyte/sec = (8/10) sec/mybte
(8/10) sec/mbyte * 100 mbyte = 80 sec = 1 min 20 sec
4.) 3 mbits/sec = (3/8) mbytes/sec = (8/3) sec/mbyte
8/3 sec/mbyte = 3(60)/8 = 22.5 mb/min
22.5 (60) = 1350 mb/hr
1350mb/hr / 60mb = 22.5 mp3/hr
