Eshaal is creating a model of a pyramid. The model created will need to be scaled up from the blueprint. triangle ACB, point D is on segment AC between points A and C, point E is on segment BC between points B and C

If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC?

answer choices~

BC = CE
BC equals AC times CE all over CD
BC equals AC times DE all over CE
BC = AC

What term makes it inconsistent y=2x - 4

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?
