The missing number is 49. This is why: 1 plus 2 equals 3, then 3 squared is 9. 2 plus 3 equals 5, then 5 squared is 25. Therefore, the missing number must be 49 to make the number sentence (3 plus 4 equals 7, then 7 squared is 49) true.
The missing addend is 1.

Yes it does, since 1 (an odd whole number) plus another 1 equals 2 (an even whole number). So only 2 plus an odd whole number equals a consecutive odd whole number. 1 plus 2 equals 3. 3 plus 2 equals 5. And so on.
The missing number is 100 because 1 meter = 100 centimeters.
0.5+0.5= 1.
This appears to be a number trick or joke. The answer is that 1 hour, plus 1 minute, plus 59 minutes, will equal 2 hours.
