4/9 of 18 is 8
So it would be 8 Liters.
Hope this helps!
A good place to start is to set to y. That would mean we are looking for to be an integer. Clearly, , because if y were greater the part under the radical would be a negative, making the radical an imaginary number, not an integer. Also note that since is a radical, it only outputs values from , which means y is on the closed interval: .
With that, we don't really have to consider y anymore, since we know the interval that is on.
Now, we don't even have to find the x values. Note that only 11 perfect squares lie on the interval , which means there are at most 11 numbers that x can be which make the radical an integer. All of the perfect squares are easily constructed. We can say that if k is an arbitrary integer between 0 and 11 then:
Which is strictly positive so we know for sure that all 11 numbers on the closed interval will yield a valid x that makes the radical an integer.
Answer:
4/7
Step-by-step explanation:
a positive will cancel out the negative number
Answer:
I hink The B is the correct one .
3x+8x=$861
11x=$861
x=78.27
So flight is 3(78.27)=$234.82
And hotel is 8(78.27)=$626.18
