I'd appreciate it if anyone ! : ) every week, nina used 5 l of water from her rain barrel to water her plants. she did this until her rain barrel was empty. when nina first started watering, her rain barrel contained 75 l of water. which sketch represents this situation? ( don't mind the filled bubble at the bottom right corner.)

The correct graph is the graph at the top right of the image given.

From the graph, we see that the water remaining is represented on the y-axis while weeks it will take for the barrel to get empty is represented on the x-axis.

This means that, the first coordinate will be; (0, 75). 0 on the x-axis and 75 on y-axis.

Number of weeks it took for the barrel to be empty = 75/5 = 15 weeks

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.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
