the number of construction workers, c, employed to restore a road is inversely proportional to the time it takes to restore the road, r. Which equation best models the number of construction workers required to restore the road?

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

i believe the answer is letter c) 8

step-by-step explanation:

if x = 1, then the answer is 3.5

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
