First expression: (-7)/(-4)
Divide. Note that two negative numbers divided will result in a positive answer
(-7)/(-4) = 7/4 = 1.75
First expression: Greater than 1.
-----------------------------------------------------------------------------------------------------------------
Second expression: -(3/2)
Simplify: 3/2 = 1.5
-(1.5) = -1.5
Second expression: Less than -1
--------------------------------------------------------------------------------------------------------------
Third expression: (-8/5) x (-5/8)
Note that two negatives = one positive answer when multiplying
8/5 x 5/8 = 40/40 = 1
Third expression: Neither
----------------------------------------------------------------------------------------------------------------
Fourth Expression: (-5)/(-3)
Divide: (-5)/(-3) = 5/3 = ~1.67
Fourth Expression: Greater than 1
----------------------------------------------------------------------------------------------------------------
Fifth Expression: (-9)/6
Divide: (-9)/6 = -1.5
Fifth expression: Less than -1
----------------------------------------------------------------------------------------------------------------

Answer:
8000π mm^3/s ≈ 25,133 mm^3/s
Step-by-step explanation:
The rate of change of volume is found by differentiating the volume formula with respect to time.
V = 4/3πr^3
V' = 4πr^2·r'
For the given numbers, this is ...
V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s
_____
<em>Additional comment</em>
By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.
They can ride their bike 12 miles because in 6 minutes they ride 0.8 miles so in 1.5 hours they ride 12 miles. 0.8 * 10 = 8 miles 1 hour so 0.8 * 5 = 4 miles 0.5 hours 8 miles + 4 miles =12 miles 1 hour + 0.5 hours = 1.5 hours
