Jason placed a mirror on the ground 40 feet from the base of the tree. he walks backwards until he can see the top of the tree in the middle of the mirror. at that point jason's eyes are 6 feet above the ground and he is feet from the image in the mirror. what is the height of the tree?

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.
