Dwayne’s garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If

zhenek [66]

Answer: Longest side = 19 ft

Explanation:

We are given a triangular shaped with two equal sides.

Let length of equal side be x ft

Third side is 4 ft longer than equal side.

Third side = (x+4) ft

Three sides of triangular garden are x, x and x+4.

The perimeter of triangular garden is 49 ft.

Perimeter of triangle = Sum of all three sides

Perimeter of triangle = 49 ft

x+x+x+4=49

3x=49-4

3x=45

x=15 ft

Longest side = x+4 => 15+4

Longest side = 19 ft

A large cylindrical cooler is 2 (1 )/2 feet high and has a diameter of 1 1/2 feet. It is filled 3/4 high with water for athletes

Ivahew [28]

So.. if hmm check the picture below, the radius is half that diameter

thus $\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\qquad 
\begin{cases}
h=height\\
r=radius=\frac{diameter}{2}\\
----------\\
h=2\frac{1}{2}\to \cfrac{5}{2}\\
diameter=1\frac{1}{2}\to \cfrac{3}{2}\\
r=\cfrac{\frac{3}{2}}{2}\to \cfrac{3}{4}
\end{cases}\implies V=\pi \left( \cfrac{3}{4} \right)^2\cfrac{5}{2}
\\\\\\
V=\pi \cdot \cfrac{9}{16}\cdot \cfrac{5}{2}\impliedby \textit{how much is }\frac{3}{4}\textit{ of that?}
\\\\\\
\cfrac{3}{4}\left( \pi \cdot \cfrac{9}{16}\cdot \cfrac{5}{2} \right)$

simplify that away

now.. that's how much is in the cooler in cubic feet though, not in gallons

notice, our units were in feet, thus our volume is also in feet, just cubics

so. to know how many gallons, simply divide that by 231

$\bf \cfrac{\frac{3}{4}\left( \pi \cdot \frac{9}{16}\cdot \frac{5}{2} \right)}{231}\quad gallons$
