A large bag contains 5/12 pounds of nails. How many 1/8 pounds bags can be filled with this amount of nails?
Amanda [17]

so, three bags can be filled and 0.33 or 0.33*(1/3) =11/100 nails will be left

Step-by-step explanation:

We will get the number of bags that can be filled from 5/12 by dividing the total amount by the 1/8

Given

Total nails in bag = 5/12 pounds

The capacity of small bag = 1/8 pounds

So,

Number\ of\ bags = \frac{\frac{5}{12}}{\frac{1}{8}}\\Simplifying\\=\frac{5}{12}*\frac{8}{1}\\=\frac{40}{12}\\=3.33\ bags

so, three bags can be filled and 0.33*(1/3) = 11/100 nails will be left

The circular bases of the traditional teepees of the Sioux and Cheyenne tribes have a diameter of about 15 ft. What is the area
LenaWriter [7]

if the diameter is 15, its radius is half that, or 7.5


\bf \textit{area of a circle}\\\\A=\pi r^2~~\begin{cases}r=radius\\[-0.5em]\hrulefill\\r=7.5\end{cases}\implies A=\pi 7.5^2\implies A=56.25\pi \\\\\\A\approx 176.71459\implies A = \stackrel{\textit{rounded up}}{177}
