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.

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle measure = 58°
Adjacent side of angle = <em>x</em>
Hypotenuse = 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [cosine]: cos58° = x/9
- Isolate <em>x</em>: 9cos58° = x
- Evaluate: 4.76927 = x
- Rewrite: x = 4.76927
- Round: x ≈ 4.8
