Answer:
Graph given on the top right side.
Step-by-step explanation:
Nina used 5 L of water from her rain barrel to water her plants every week.
She did this until her rain barrel was empty.
So barrel will be empty in the time = weeks.
Nina started watering when rain barrel contained 75L of water.
We draw a graph with water remaining on y-axis and weeks to get the barrel empty on x-axis.
Line representing this process will start from a point (0, 75) on y-axis and will end at x-axis at the point (15, 0).
Therefore, graph given on the top right side of the options is the correct answer.

Answer:
67%
Step-by-step explanation:
There are a few methods to finding the percent of a number. You can use proportions:
The 'percent' is the percent of the fraction that you are looking for, or 48/72.
Cross-multiply: 72x = (48)(100) or 72x = 4800
Divide both sides by 72: 72x/72 = 4800/72
Solve for 'x': x = 66.6666...
Round 66.666.... to the nearest percent: 67%
