The population of a city has increased by 34% since it was last measured. If the current population is 73,700, what was the previous population?

the previous population would be 48,642 people

Step-by-step explanation:

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.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
