You would need about 34  2/3 tablespoons of butter. Convert the fraction into an improper fraction, so 8/3. Then multiply that by 13 (you and your brother are included in the 15 people I suppose) and you get 104/3. Simplify that to get a mixed number and you have 34  2/3.

If you use 2 2/3 tablespoons for you and your brother, that means, you need 2 2/3 tablespoons for two servings, how many tablespoons for 15 servings then?

well  \bf 2\frac{2}{3}\implies \cfrac{2\cdot 3+2}{3}\implies \cfrac{8}{3}\\\\
-------------------------------\\\\
\begin{array}{ccllll}
\textit{butter spoons}&servings\\
-----&-----\\
\frac{8}{3}&2\\
x&15
\end{array}\implies \cfrac{\frac{8}{3}}{x}=\cfrac{2}{15}\implies \cfrac{\frac{8}{3}}{\frac{x}{1}}=\cfrac{2}{15}
\\\\\\
\cfrac{8}{3}\cdot \cfrac{1}{x}=\cfrac{2}{15}\implies \cfrac{8}{3x}=\cfrac{2}{15}\implies 8\cdot 15=3x\cdot 2\implies 120=6x
\\\\\\
\cfrac{120}{6}=x\implies 20=x

Answer:

<h2>x = 745.5 ft</h2>

Step-by-step explanation:

Look at the picture.

Use sine:

sine=\dfrac{opposite}{hypotenuse}

We have a measure of the angle and length of the opposite:

\alpha=28^o,\ opposite=350\ ft

\sin28^o\approx0.4695

Substitute:

\dfrac{350}{x}=0.4695

\dfrac{350}{x}=\dfrac{4695}{10000}            <em>cross multiply</em>

4695x=3500000           <em>divide both sides by 4695</em>

x=\dfrac{3500000}{4695}\to x\approx745.5
