Employees at a hardware store or receiving pay raise is Kathy’s hourly rates are increasing from $13-$15 what is the percent of change in Kathy’s salary? (Round to the nearest 10th of a percent if needed.)

If a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin(a+b).

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.
