ANSWER
(a) 1100
Binary
No Power Value Result
0 (LSB) 20 1 0x1=0
0 21 2 0x2=0
1 22 4 1x4=4
1 (MSB) 23 8 1x8=8
Equivalent decimal number = 4 + 8 = 12
Therefore, (1100)2 = (12)10
(b) 10010101
Binary
No Power Value Result
1 (LSB) 20 1 1x1=1
0 21 2 0x2=0
1 22 4 1x4=4
0 23 8 0x8=0
1 24 16 1x16=16
0 25 32 0x32=0
0 26 64 0x64=0
1 (MSB) 27 128 1x128=128
Equivalent decimal number = 1 + 4 + 16 + 128 = 149
Therefore, (10010101)2 = (149)10
(c) 11011100
Binary
No Power Value Result
0 (LSB) 20 1 0x1=0
0 21 2 0x2=0
1 22 4 1x4=4
1 23 8 1x8=8
1 24 16 1x16=16
0 25 32 0x32=0
1 26 64 1x64=64
1 (MSB) 27 128 1x128=128
Equivalent decimal number = 4 + 8 + 16 + 64 + 128 = 220
Therefore, (11011100)2 = (220)10
Explanation:
Climate is the long-term pattern of weather in a particular area. Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. A region's weather patterns, usually tracked for at least 30 years, are considered its climate.
