Suppose that `y` is inversely proportional to `x`.

Find the constant of proportionality `k` if `y = 11` when `x = 13`.

`k =`

Using the `k` from above write the variation equation in terms of `x`.

`y =`

Using the `k` from above find `y` given that `x = 30`.

`y =`

If needed, round answer to 3 decimal places.
