Answer:
9 scarves.
Step-by-step explanation:
We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.
We know that equation of two inversely proportional quantities in in form 
, where, k is constant of variation and y is inversely proportional to x.
Let us find constant of variation using our given information.
Now, we will substitute 
in our equation to solve for N.
Therefore, Ariana can make 9 scarves.
Answer:
4/15
Step-by-step explanation:
You would do it as follows
I-8/15I reduce the fraction by 2
I-4/25I the absolute fraction is always positive
So the solution is
4/25
Alternative forms are:
0.16 or (2/5)^2 (Just incase)
Answer:
say it in English plZz
I can't understand Spanish or whatever ur saying sorry
You are given a table in which each row represents the coordinates of points. For example, in the first line, we have x=-7 and y=5. Work through the four given equations, one at a time, subbing -7 for x and 5 for y; is the equation still true? If yes, then you have found the correct answer. B is the exception; I'd suggest you check out equations A, C and D first, before focusing on B.
Example: D: (5)-5 = 2((-7) + 7) leads to 0 = 0. Is that true? If so, D is likely the correct answer.
Answer:
Irrational.
Step-by-step explanation:
Rational means that it is a whole number and can be written as a fraction. That doesn't apply for square rooted numbers. So, 
is irrational.
