South High School began the school year with 1125 students. They have
lost 4% of their student body due
to attrition.
How many students has South
High School lost to attrition?

45

Step-by-step explanation:

1125 students×.04 attrition =45 students lost

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

its 69.420
