Answer: Irrational
I'm going to write 'x' in place of "square root of 2" just to save time. Let's consider the possibility that 7-x is rational. I'm going to show there's a contradiction which ultimately concludes that the expression is irrational.
If 7-x was rational, then 7-x = p/q for some integers p,q with q being nonzero. Solve for x to get
7-x = p/q
-x = (pq) - 7
x = -(p/q) + 7
x = 7 - (p/q)
x = (7q/q) - (p/q)
x = (7q-p)/q
So if 7-x were rational, then this forces x to be rational because 7q-p is an integer over q (also an integer). The format is rational = integer/integer. But this is where the contradiction lies. Remember that x is standing in place for "square root of 2", which is an irrational number. There is no way to write sqrt(2) as a ratio of two integers. So x cannot be both rational and irrational at the same time.
Therefore, 7-x must be irrational making 7-sqrt(2) to be irrational as well.
note: sqrt is shorthand for "square root"
another note: adding any rational number to an irrational number will always result in an irrational number.
Answer:
Depends on if someone's paddling, how fast the current is going, when the put the raft down, and how long the raft was down.
Step-by-step explanation:
By not completing the question there are a lot of questions within that particular question to figure out and ask questions about.
Im pretty sure that you just take 128 devided by 98 and more the decimal to get the result of 13%
First, find the total number of ounces:
(28)(16) = 448 oz (16oz in a lb)
Then divide 448 by 8
448/8 = 56 days of food
