## Answer :

[tex]C=\frac{1}{8}*R*t \\\\ C=\frac{Rt}{8} \\\\ \boxed{R=\frac{8C}{t}}[/tex]

Multiply both sides by 8.

8C=Rt

Divide both sides by t.

[tex] \frac{8C}{t} [/tex]=R

C=1/8Rt

[tex]C=\frac{1}{8}*R*t \\\\ C=\frac{Rt}{8} \\\\ \boxed{R=\frac{8C}{t}}[/tex]

Multiply both sides by 8.

8C=Rt

Divide both sides by t.

[tex] \frac{8C}{t} [/tex]=R
