The unit ratio of FTE enrollment at College C to the FTE enrollment at College B is ?

Plz hurry evaluate the expression a+b where a=8 and b=19

Determine the common ratio and find the next three terms of the geometric sequence. 10, 2, 0.4, a. 0.2; -0.4, -2, -10 c. 0.02; 0.08, 0.016, 0.0032 b. 0.02; -0.4, -2, -10 d. 0.2; 0.08, 0.016, 0.0032 select the best answer from the choices provided a b c d

Collin did the work to see if 10 is a solution to the equation r/4=2.4
