    #1) Using the given info, y=kz and  y=\frac{k}{\sqrt{r}} for some constant k. The question said that the constant of proportionality is the same for both and that this value is 10. Thus y=10z and  y=\frac{10}{\sqrt{r}}. You can solve each question using basic algebra from here.

    I think the question is trying to say:

    <br />
y=k\frac{z}{\sqrt{r}}<br />

    and that k=10.
