A wall in Marcus's bedroom is 8 2/5 feet high and 18 1/3 feet long. If he paints 1/2 of the wall blue, how many square feet will
goldenfox [79]
\bf \textit{so the area of the wall is then }8\frac{2}{5}\times 18\frac{1}{3}
\\\\\\
\textit{how much is }\frac{1}{2}\textit{ of that product?}\quad \cfrac{8\frac{2}{5}\times 18\frac{1}{3}}{2}\\\\
-------------------------------\\\\

\bf \begin{cases}
8\frac{2}{5}\implies \cfrac{8\cdot 5+2}{5}\implies &\cfrac{42}{5}\\\\
18\frac{1}{3}\implies \cfrac{18\cdot 3+1}{3}\implies &\cfrac{55}{3}
\end{cases}
\\\\\\
\cfrac{8\frac{2}{5}\times 18\frac{1}{3}}{2}\implies \cfrac{\frac{42}{5}\cdot \frac{55}{3}}{\frac{2}{1}}\implies \cfrac{\frac{42\cdot 55}{5\cdot 3}}{\frac{2}{1}}\implies \cfrac{42\cdot 55}{5\cdot 3}\cdot \cfrac{1}{2}\implies \cfrac{42\cdot 55\cdot 1}{5\cdot 3\cdot 2}
\\\\\\
\cfrac{2310}{30}\implies 77

11. What's the perimeter of a regular heptagon if one side measures 3 inches?
NemiM [27]
When a polygon is regular, that means that all of its sides are the same length and all of its angles are the same. A heptagon has seven sides and you know that all of them measure 3 inches. You can find the perimeter by adding all of the side measures together, so 3 + 3 + 3 + 3 + 3 + 3 + 3, or 3 x 7. So, the perimeter of the heptagon is 21 inches.

Between which two consecutive integers is the negative square root of 5
kogti [31]

Answer:  Between the numbers -2 and -3  

Step-by-step explanation:

The negative square root of 5 will be slightly greater than 2 because the square root of 4 is 2 and 5 is greater than 2. The negative square root of 5  will not be greater than -3 because 3 squared is 9. So it has to be between -2 and -3.
