Inlet pipe #1 can fill a pool in 8 hours. Inlet pipes #1 and #2 together can fill the pool in 6 hours. How long will it take inlet pipe #2 to fill the pool by itself?

24hours

Step-by-step explanation:

We list the conditions as A and B

a. If inlet pipe #1 will fill the pool in 8 hours, the the portion of the pool that will be filled in one hour by inlet pipe 1 = 1/8.

b. If inlet pipe #1 and #2 will fill the pool in 6 hours, then the portion of the pool that inlets pipe #1 and #2 combined will fill in one hour = 1/6.

Now to get the portion of the pool that will be filled in one hour if only inlet #2 is running becomes:

condition b - condition a

= 1/6 - 1/8

= 2/48

= 1/24.

Since 1/24 is the portion of the pool that will be filled in one hour, then it will take 24hours for inlet #2 alone to fill the entire pool.

i think 1: 2

step-by-step explanation:

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
