Which of the following proportions could be used to convert 3600 feet into miles
x/3600ft=5280ft/1mi

3600/x=5280/1

3600/5280=1

3600/1=5280/x

Go with the 2nd choice.

Step-by-step explanation:

When using proportions to solve for unknown quantities, you need to keep the same units on the same side. This means keep "ft" on the top side and "mi" on the bottom side.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
