The Perimeter Of A Rectanglular Garden Is 84 Feet . The Length Of The Garden Is Twice The Width . What Is The Width Of The Garde

nalin [4]

$\bf \stackrel{\textit{perimeter of a rectangle}}{P=2L+2W\implies 2(L+W)}~~
\begin{cases}
L=length\\
W=width\\
--------\\
P=84\\
L=\stackrel{\textit{twice the width}}{2W}
\end{cases}
\\\\\\
84=2(L+W)\implies \cfrac{84}{2}=L+W\implies 42=L+W
\\\\\\
42=(2W)+W\implies 42=3W\implies \cfrac{42}{3}=W\implies 14=W$

Ramiro is 3/10 as tall as the flagpole. The flagpole is 5/9 as tall as the nearby tree. The tree is 32 2/5 feet tall. How tall i

djyliett [7]

$x-\ Ramiro's\ height\\
y-\ Flapole's\ height\\
z-\ nearby\ tree\\\\
x=\frac{3}{10}y\\
y=\frac{5}{9}z \\z=32\frac{2}{5}\\\\\y=\frac{5}{9}*32\frac{2}{5}=\frac{5}{9}*\frac{162}{5}=18\\\\
x=\frac{3}{10}*18=5,4\\\\
Ramiro\ is\ 5,4\ feet\ tall.$

Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did

In-s [12.5K]

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\to &\$450\\
P=\textit{original amount deposited}\to& \$3000\\
r=rate\to r\%\to \frac{r}{100}\\
t=years\to &3
\end{cases}
\\\\\\
450=3000\cdot r\cdot 3\implies \cfrac{450}{3\cdot 3000}=r\implies \cfrac{1}{20}=r
\\\\\\
r\%\implies \cfrac{1}{20}\cdot 100\implies r=\stackrel{\%}{5}$
