The population of baltimore was 520,000 in 2000. now its 750,000. what was the change in population? what was the precent of change?

The change is 230,000 people.

750,000 - 520,000 = 230,000

there was an increase of 230,000.

the percent of change...

520,000/750,000 = 0.69

0.69 times 100 = 69 percent

hope this helps :)

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
