How do I do this problem?
goldenfox [79]

so a quadrilateral is a figure with 4 sides. So looking at the picture I see 5 rhombi and 7 squares. So all together thats 12 quadrilaterals  

So to find the ration you have to do:

amount of thing: whole

so in this case it would be

12:24

which you can simplify

normally you'd simplify to 1:2 but that doesn't seem like an option so I'd go with the one closest to that ratio

as Saturn revolves around the sun, it travels at a speed of approximately 6 miles per second. convert this speed to miles per mi
3241004551 [841]

Given:

Speed = 6 miles per second

If the Saturn revolves 6 miles in 1 second then the speed is:

\begin{gathered} In\text{ 1 second distance is 6 miles} \\ So\text{ in 60 second distance is =6}\times60\text{ miles} \\ =360 \end{gathered}

So speed in minutes is 360 miles per min.

In 3 minutes traveling distance is:

\begin{gathered} =360\times3 \\ =1080 \end{gathered}
