A rectangular plot of land width 4.5m requires a wire mesh of length 32m to fence it. what is the length of the plot

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu

approximately 5 hours 32 minutes

let x be the amount of it takes both pumps to fill and 1 pump to empty

so the pumps fill/empty at the rate of per hour

first pump fills at a rate of per hour

second pump fills at a rate of per hour

third pump empties at a rate of per hour

together the reservoir fills at a rate of

+ - =

multiply each term by 720x

120x + 90x - 80x = 720

130x = 720 ( divide both sides by 130 )

x = = 5. hours

(0. × 60 ≈ 32 minutes )

time taken to fill reservoir is 5 hours 32 minutes
