What is the decimal integer value for the binary code 0000-1001?

• A. 7
• B. 9
• C. 11
• D. 1001

Answer: (B)

To find the decimal integer value of the binary code 0000-1001, it's essential to understand how binary numbers work. In binary representation, each digit (bit) corresponds to a power of 2, starting from the rightmost bit, which is 2^0. Looking at the binary number 0000-1001, we can break it down as follows: - The rightmost bit (the first '1') represents 2^0, which is 1. - The second bit from the right (the second '0') represents 2^1, which is 0. - The third bit (the third '0') represents 2^2, which is also 0. - The fourth bit (the fourth '0') represents 2^3, which is still 0. - The fifth bit (the fifth '1') represents 2^4, which is 0. - Continuing left, the next bits are all 0, leading us to the leftmost bit as 0 as well. Thus, in terms of addition for the binary number 0000-1001: - 0 (from 2^4) + 0 (from 2^3)

To find the decimal integer value of the binary code 0000-1001, it's essential to understand how binary numbers work. In binary representation, each digit (bit) corresponds to a power of 2, starting from the rightmost bit, which is 2^0.

Looking at the binary number 0000-1001, we can break it down as follows:

• The rightmost bit (the first '1') represents 2^0, which is 1.

• The second bit from the right (the second '0') represents 2^1, which is 0.

• The third bit (the third '0') represents 2^2, which is also 0.

• The fourth bit (the fourth '0') represents 2^3, which is still 0.

• The fifth bit (the fifth '1') represents 2^4, which is 0.

• Continuing left, the next bits are all 0, leading us to the leftmost bit as 0 as well.

Thus, in terms of addition for the binary number 0000-1001:

• 0 (from 2^4) + 0 (from 2^3)
