The table below shows the multiplicative inverses of the first $9$ positive residues modulo $47$.

\begin{tabular}{c|ccccccccc}  $b$ & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\ \hline  inverse of $\,b$ & 1 & 24 & 16 & 12 & 19 & 8 & 27 & 6 & 21  \end{tabular}

Find the multiplicative inverse of $10\pmod{47}$.  Express your answer as an integer from $0$ to $46$, inclusive.
