ray was in charge of filling the soccer team’s water jug for practice. at the beginning of practice he filled the jug. halfway through practice the team took a water break. after the break ray refilled the jug so the players could have water after practice. at the end of practice ray drained the jug. which graph could represent the level of the water in the jug during and after practice?

The third graph.

Step-by-step explanation:

Before practice, the jug was empty.  This means it starts at 0.  Ray fills the jug up; this will be the graph increasing, starting at 0, until the jug was filled.

The jug stays at the same level during practice; this means the graph will be constant during this time.

Halfway through practice the players drink from the jug.  During this time the graph will be decreasing.

Ray then fills the jug back up; this means the graph will increase.

During the rest of practice, the jug stays at the same level; the graph will be constant during this time.

After practice Ray drains the jug.  This means the graph will decrease during this time.

your exact question is kind of difficult to understand, so maybe an example will explain what you're supposed to do? i'll work through the first problem on the worksheet.

suppose you have a tray of 652 brownies, and you have 5 friends that you want to feed without picking favorites. how many brownies can you dole out to each of your friends in equal amounts? how many will be left over for you to eat?

what you're doing here is finding a way to arrange the number 652 as the sum of integer multiple of 5 and some remainder:

here ("q" for quotient) is the number of brownies each of your friends get, and is the remainder. that's the basic idea behind division.

we break up the number 652 into parts so that the leading digit stands on its own:

652 = 600 + 52

first we check if it's possible to hand out exactly 100 brownies to each friend. with 5 friends, this means we want to know if we can take out 500 brownies from the tray. we can do this 1 time because we have 600 brownies to take from, and when we do that we're left with 100 + 52 brownies to divvy up. so we know that

652 = 1*500 + 152

next we want to know if it's possible to hand out exactly 10 brownies per friend. if we can, we have to remove 50 brownies from the tray each time until we can't. we have 152 brownies left, and we know that 3(50) = 150, so

152 = 3*50 + 2

now we have 2 brownies left in the tray. is it possible to hand 1 out to each of your 5 friends? no, you'd need a minimum of 5 brownies to do that. so the last 2 are yours.

putting everything together, we found that

652 = 1*500 + 3*50 + 2

and we can rearrange this to write

652 = 5*100 + 5*30 + 2

652 = 5(100 + 30) + 2

652 = 5*130 + 2

so and .

you might be more accustomed to the table depicting the algorithm. that's just a compact way of organizing what we've done above. you can consult the image i've attached below.
