Answer:
$0.45
Step-by-step explanation:
1 pint = 2 cups
so 2 pints = 4 cups, $1.80
so 1 cup is 1.80/4 = $0.45
Hi there!
In order to answer your question, you'll need to use the cross product method (let's say that Newtons = N):
9N on Earth = 2N on Namar
400N on Earth = xN on Namar
(2 × 400) ÷ 9 = xN on Namar
800 ÷ 9 = xN on Namar
88.888.. = xN on Namar
Since your answer must be to the nearest Newton, I'm guessing that you need to round your answer to the nearest whole number. This means that since the number in the tenths column is more than 5 (could also be equal to 5), you need to round the number up.
88.888... rounded to the nearest whole number = 89
Your answer is: The girl weigh 89 newtons on Namar.
There you go! I really hope this helped, if there's anything just let me know! :)
By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.
<h3>How to find the water left for the third beaker</h3>
In this question we know that Karen has 3 liters of water and poured 0.7 liters into the <em>first</em> beaker, 1.4 liters into the <em>second</em> beaker and we can determine the water left for the <em>third</em> beaker by subtracted the water poured into the <em>first two</em> beakers from the available water. The available volume is:
V = 3 L - 0.7 L - 1.4 L
V = 0.9 L
By subtracting the water poured into the first two beakers from the available water we conclude that the water left for the third beaker is 0.9 liters.

Answer:
Step-by-step explanation:
Not exactly sure what your question is - I am assuming that it is something like:
Show/prove that for any integer x, x^2 - x is even.
Suppose that x is an even integer. The product of an even integer and any other integer is always even (x = 2n, so x * y = 2 n * y which is even. Therefore x^2 is even. An even minus an even is even. (The definition of an even number is that it is divisible by 2 or has a factor of 2. So the difference of even numbers could be written as 2*( the difference of the two numbers divided by 2); therefore the difference is even)
Suppose that x is an odd integer. The product of 2 odd numbers is odd - each odd number can be written as the sum of an even number and 1; multiplying the even parts with each other and 1 will produce even; multiplying the 1's will produce 1, so the product can be written as the sum of an even number and 1 - which is an odd number. The difference between two odd numbers is even - the difference between the even parts is even (argument above), the difference between 1 and 1 is zero, so the result of the difference is even.
x^2 is therefore even if x is even and odd if x is odd; The difference x^2 - x is even by the arguments above.
