Alani paid $8:50 to get in the movies. Before she left home, her parents gave her $20 to spend. If she bought candy that cost $3 each, how many pieces of candy can she buy without going over the $20?

She can by 3 pieces of candy after going to the movies.

Step-by-step explanation:

Subtract 8.50 from 20

Divide 3 from 11.50

You get 3 with a remainder of 2.50

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
