2. 101010, 2+8+32 = 42

3. 11111, 1+2+4+8+16 = 31

4.10010, 2+16

2. Converting from base 10 to base 2

1. 31, (31-16=15-8=7-4=3-2=1-1=0) = 11111  

2. 51, (51-32=19-16=3-2=1-1=0) = 110011

3. 7,  ( 7-4=3-2=1-1=0 = 111

4. 103, (103-64=39-32=7-4=3-2=1-1=0) 1100111

3. 

A. modem downloading @ 56 kilobits/sec  

(100MB/1)*(1,048,576B/1MB)=104,857,600Bytes

*(8bits/1bytes)=838,860,800bits*(1kilobit/1000bits)=838860.8kilobits*(1sec/56kilobits)=

ANSWER: 14979.657seconds 

B. DSL downloading @ 5megabits/sec 838,860,800bits*(1megabit/1,000,000bits)=838.8608megabits*(1sec/5mega)=ANSWER:167seconds

C.Highspeed downloading @ 10megabits/sec

838,860,800bits*(1megabit/1,000,000bits)=838.8608megabits*(1sec/10mega)=ANSWER:83seconds

4. 60megabytes*(8megabits/1megabytes)=480megabits(MP3)*(1sec/3mb)=160=2.667min

60/2.667=ANSWER: 22.5/hour
