The answer is 103 I finished this question just now
Answer:
20 tests
Step-by-step explanation:
There are six different wires, and for each test the author picks three, this means that each test is a combination of three out of six wires (₆C₃) . The number of total combinations possible is given by:
20 tests are required to verify every possible pairing of three wires.
Rational numbers are numbers that can be expressed as a fraction (ratio). Irrational numbers can not be expressed like that (like sqrt(2)).
To prove your statement, assume the opposite until you have a contradiction.
If the result of adding them would be rational, then your irrational number can be expressed as the difference of two rational numbers, which itself is also a rational number. That cannot be, because it should be an irrational number. This contradiction forces that rational + irrational = irrational.
You can reason the same way for multiplication. Suppose rational * irrational = rational, you find that your irrational can be expressed as the fration of two rationals, which is a contradiction.

580-29=551
Answer
N/A
Step-by-step explanation:
lets take a step into our imaginations, ok?
So when you divide, you're basically splitting the numerator into as many parts as the denominator.
imagine you have a chocolate bar, and it has 6 pieces and you want to split it evenly between your 3 friends.
you split it into three equal parts to get 2 pieces per person.
When you divide 0 by 0, your splitting 0 chocolate bars into 0 equal portions, which is why this problem isn't solvable.
