Answer:

The volume of the marble is 47 ml

The volume of the water is 100 ml

Step-by-step explanation:

we know that

The volume of the marble is equal to the change in water level

so

To find out the volume of the marble subtract 100 ml from 147 ml

147-100=47\ ml

The volume of the water no change

The volume of the water is 100 ml

Jackie's restaurant bill was $23. 50, and the tax was 8%. Jackie left a 20% tip on the post-tax bill. How much was the tip Jacki
Ksju [112]

well, the subtotal or pre-tax bill is $23.50, now let's add the 8% tax and

\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{8\% of 23.50}}{\left( \cfrac{8}{100} \right)23.50}\implies 1.88

so the post-tax bill is 23.50 + 1.88 = 25.38, and Jackie's tip is 20% of that

\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{20\% of 25.38}}{\left( \cfrac{20}{100} \right)25.38}\implies 5.076\qquad \approx 5.08
