Question

1. what numbers would you subtract to get the answer of 112? (be sure to put a number in each blank. use 0 if there isnt a different number that should be put into the box.)(be sure to put a number in each blank. use 0 if there isnt a different number that should be put into the box.)

(the chart has columns with numbers 1/32, 64, 32, 16 and rows with numbers 4, 2, 1, and empty rows. the first row has a dot in the 1/32 column and 4 in one of the other columns, etc.)

1. why does a computer use binary? (select the most correct answers)

□ binary is a state of on/off or true/false.
□ binary 10 was too complicated for the computer.
□ binary is not too complicated for the computer.
□ binary 10 was already used in our money system.

Explanation:

For question 5: Computers use binary because their hardware is based on two states (on/off, high/low voltage), which maps directly to binary's true/false (1/0) states. The other options are incorrect: base 10 is not too complicated for computers, binary is simple for hardware, and the money system's use of base 10 is irrelevant to computer design.
For question 6: First, convert 112 to binary by finding the largest powers of 2 less than or equal to 112, then assign 1s to the columns where the power is used, 0s otherwise.

Answer:

1. Binary is a state of on/off or true/false.
