Amachine paints 340 toy boats in 45 minutes what is the unit rate per hour

where is the image?

step-by-step explanation:

part a: 1.08

part b: 27.59

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
