You can use feet or inches because they are both on the diagram and they are both a part of the same measuring system. If you use inches, you would be using larger numbers, but if you used feet, you would be using fractions.
I hope this helps!
The correct answer is C, 6/7
6:3 = 6/3 = 2
13 to 4 = 13:4 = 13/4 = 3.25
19/2 = 9.5
15 to 10 = 15:10 = 15/10 = 1.5
8:2 = 8/2 = 4
From the least to the greatest:
15 to 10 , 6:3, 13 to 4, 19/2
I hope this explains it.
There are 5280 feet in a mile
45 * 5280 = 237600
there are 3600 seconds in an hour (60 minutes time 60 seconds)
so we have 237600 feet in 3600 seconds
237600 / 3600 = 66 feet per second.
9 < = 6 - y
9 - 6 < = -y
3 < = -y
-3 > = y or y < = -3
solutions include : -3,-4,-6
