Atank contains 9,000 l of brine with 17 kg of dissolved salt. pure water enters the tank at a rate of 90 l/min. the solution is kept thoroughly mixed and drains from the tank at the same rate. (a) how much salt is in the tank after t minutes? y = | 14400011-e -(100)|x kg (b) how much salt is in the tank after 20 minutes? (round your answer to one decimal place.) kg

d is correct

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
