This year, druehl, inc., will produce 57 comma 60057,600 hot water heaters at its plant in delaware, in order to meet expected global demand. to accomplish this, each laborer at the plant will work 160160 hours per month. if the labor productivity at the plant is 0.150.15 hot water heaters per labor hour, how many laborers are employed at the plant?

We know that:

rate = 0.15 heaters /labor  hour

labourer time = 160 hours / month

goal = 57,600 heaters / year

We can solve this problem by simply looking at which ratios will cancel out the units:

number of labourers = (57,600 heaters/year) / [(0.15 heaters /labor  hour) * (160 hours/month) * (12 month/year)

number of labourers = 200

step-by-step explanation:

because i said it is

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
