An inlet pipe on a swimming pool can be used to fill the pool in 6 hours. The drain pipe can be used to empty the pool in 8 hours. If the pool is 12 filled and then the inlet pipe and drain pipe are opened, how long from that time will it take to fill the pool?

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

i think it would be c
