So 126 miles per hour is 126 miles per 60 minutes, which is 126 miles per 3600 seconds. Then, there are 5280 feet in a mile, so 126*5280=665280. Then divide 665280 by 3600 to get 184.8 feet per second.

Indifference is uninterest and contempt is just disrespect if that answers your question. So you could interpret this sentence as "I tried to treat them with uninterest and disrespect." Clearly, this person in the sentence doesn't care about something.

There are six 4s being multiplied by each other, so the answer would be 4^6

Since you are multiplying 2 negative numbers by each other, it gives the same solution as 3*45 which is 135

Irrational numbers cannot be written as a simple fraction, which the square root of 23 is. 23 can be written as a simple fraction (so maybe 46/2 or 23/1 or any other equivalent fraction).

Any number that's between -5 and 2, but not including them, will work. So they are -4, -3, -2, -1, 0, and 1.

You must multiply 3.2 by 2 first, then subtract that from 10. So 10-6.4=3.6.
