If y varies directly as x, and y is 400 when x is r and y is r when x is 4, what is the numeric constant of variation in this re

Kipish [7]

$\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
\\
&& y={{ k }}x
\end{array}\\\\
-----------------------------\\\\
$

$\bf \textit{now, we also know }\qquad 
\begin{cases}
y=400\\
x=r\\
---\\
y=r\\
x=4
\end{cases}\implies 
\begin{cases}
400=kr\\
r=k4\\
----------\\
now\\
400=kr\implies \frac{400}{k}=\boxed{r}\\\\
thus\\\\
r=k4\implies \boxed{\frac{400}{k}}=4k
\end{cases}
\\\\\\
400=4k^2\implies \cfrac{400}{4}=k^2\implies 100=k^2\implies \sqrt{100}=k
\\\\\\
10=k\impliedby \textit{constant of variation}$

Which is bigger, 7/8" or 9/16"?

Iteru [2.4K]

7/8 and 9/16

7*2/8*2 = 14/16

14/16 and 9/16

Now since we have a common denominator, we can compare the numerators.

14/16 is greater, so 7/8 is greater than 9/16

Answer: 7/8 is bigger
