Answer:

The percentage change is 20%.

Step-by-step explanation:

Initial attendance was 500

Change in attendance is = 100

So, the changed attendance is either 400 or 600.

Percent change in attendance = 100 * (change in attendance/Initial Attendance)

= 100 * (1/5)

= 20%

A plane traveled 460 mph with the wind and 400 mph against the wind. Find the speed of the plane in still air and the speed of t
Fudgin [204]
Let's say the speed of the plane is "p", and the speed of the wind is "w".

when the plane goes with the wind, is not really going "p" mph fast, is really going "p + w" mph fast, because the wind is adding speed to it.

likewise when the plane is going against the wind, is also not going "p" fast is going "p - w" mph fast.  Therefore,

\bf \begin{cases}
p+w=460\implies \boxed{w}=460-p \\
p-w=400\\
----------\\
p-\left( \boxed{460 - p} \right)=400
\end{cases}
\\\\\\
2p-460=400\implies 2p=860\implies p=\cfrac{860}{2}\implies p=430

Which pair of ratios form a true proportion
Delicious77 [7]
Hey there! 

I'd say your answer would most likely be Option C

Because you can multiply the \frac{3}{5} by 2 (numerator and denominator by 2 ) to get the fraction \frac{6}{10}

\frac{3(2)}{5(2)} =  2(3) = 6 = 5(2)= 10 =  \frac{6}{10}

Good luck on your assignment and enjoy your day!
