Sarah competes in a long jump competition.

Mathematics
1 answer:
hammer [34]3 years ago
8 0
How to find Sarah’s best jump:
First you multiply 4.25 by 12% (or 0.12) to get 0.51 meters.
4.25 + 0.51 = 4.76 meters. So her best jump is 4.76 meters.
How to find the winning jump:
Since her best jump is 15% less than the winning jump, it must be 85% of the winning jump (as in 85 is 85% of 100).
So you divide 4.76 by 85% (or 0.85) which equals 5.6 meters.
So, the winning jump was 5.6 meters.

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}
