William is in the middle of swimming in a ten-mile race. He swims at a steady speed, and then slows down, stops to eat, swims faster to get back in the race, and returns to a steady speed. He later stops for water, and then again swims faster to get back in the race. Which graph best represents the situation? A graph with time on the x-axis and speed on the y-axis. The graph is constant, decreases to 0, increases, is constant, decreases to 0, and then increases.

Step-by-step explanation:

The attachment shows the description of the swimmer's activity as given in the problem statement, and compares it to the descriptions of the graphs that have the closest match.

As you can see, neither graph description matches exactly. If we assume that "stops to eat" and "stops for water" do not mean the speed stayed zero long enough to be "constant", then graph choice A (the first one) seems the best match.

Step-by-step explanation:

answer: 5100 just subtract

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
