Answer:

Step-by-step explanation:

A: 2/3 - 1/8 = 16/24 - 3/24 = 13/24 which is greater than 1/3. 8/24 = 1/3

B: 5/6 - 1/4 = 20/24 - 6/24 = 14/24 which is greater than 1/3. 8/24 = 1/3

C: 10/15 - 6/15 = 4/15. 5/15 = 1/3. This is smaller than 1/3

D: 1 1/4 - 1 1/8 = 1/8 which is less than 1/3

A water storage tank has the shape of a cylinder with diameter 14 ft. It is mounted so that the circular cross-sections are vert

Check the picture below.

neverminding for a few seconds the volume of the cylinder, the percentage in the height used by the water will be the same as the percentage of its volume. We know the total amount or 100% of the height is 14, so what is 11 in percentage?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 14&100\\ 11&x \end{array}\implies \cfrac{14}{11}=\cfrac{100}{x}\implies 14x=1100 \\\\\\ x = \cfrac{1100}{14}\implies x = \cfrac{550}{7}\implies \boxed{x \approx 78.6}$
