The length is gonna be 89 ft
72+72+89+89=322 ft
Well, let's say we start with 10 granola bars.
we take away 3 of them, so there would end up being 7 left.
I assume your teacher is asking for you to write a numerical expression. In this case that would be 10-3=7.
1 day = 750 m
1 * 7 = 750 * 7
7 days = 5250 m
Now, since 1 km = 1000 m, this means in order to convert from meters to kilometers you must divide by 1000
5250 / 1000
= 5.25 km
Or, you could do the hard way by going to wolfram alpha / google and typing 5250 m to km.
Hope this helps!
5/7. You are eliminating one of the 8 original lockers yet you still have 5 possible stars left. Hence a probability of 5 stars over 7 possible lockers left. 5/7 = .7143 or 71.43 %
