A24- gallon fish tank is completely filled. water is then continually added to the tank at a rate of 2 3/8 gallons per hour, and water is removed at a rate of 2 5/8 gallons per hour. the tank now has less than 20 gallons of water. how many hours (h) has it been since the tank was completely full?

your answer should be 8 hours

the answers c

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.
