Correct Answer
B. 1011000Explanation
The given binary number 1011000 is equivalent to the decimal number 88. In binary, each digit represents a power of 2, starting from the rightmost digit as 2^0, then 2^1, 2^2, and so on. By adding up the decimal values of the digits that are 1, we get 64 + 16 + 8 = 88. Therefore, the binary number 1011000 is equivalent to the decimal number 88.Rate this question:

Correct Answer
C. 100001Explanation
The correct answer is 100001. This is the binary representation of the decimal number 33. In binary, each digit represents a power of 2, starting from the rightmost digit. So, reading from right to left, the first digit represents 2^0 (which is 1), the second digit represents 2^1 (which is 2), the third digit represents 2^2 (which is 4), and so on. Adding up the values of the digits in the binary representation of 100001, we get 1 + 0 + 0 + 0 + 0 + 32, which equals 33. Therefore, 100001 is the binary representation of 33.Rate this question:
