Its 6 hours.

I should probably explain it, the reason for this is mainly just by dividing the fact that adding the other hose takes away 8 hours of work we can deduce that the amount of water it can put out can do it 2 times faster than the normal hose so the answer is 6

Need help. <br><br> Enter an inequality that represents the graph in the box.
xxMikexx [17]
First you need to form a worthy equation using slope-intercept (y=mx+b). Do that by counting the slope and finding the y-intercept. Then you have to choose between < or > to make it more accurate. In order to do so, you would have to pick a point with a point x and y and see wether or not I’m the equation is true when you put it in the blanks. If it’s true then you would shade whichever region the point is. If it’s false then shade the opposite region.

Good luck!!!!!!! :)

docker41 [41]

Answer:

red segment = 25.12 ft

Step-by-step explanation:

circumference of full circle = (3.14)(24) = 75.36 ft

semi circle = 75.36/2 = 37.68 ft

60° segment = (60/360)(75.36) = 12.56 ft

red segment = 37.68 - 12.56 = 25.12 ft
