Carrie needs to make 16 costumes for the school play. each costume requires 2 1/4 yards of material. how many yards of material will she need?

36 yards; to get this, you would multiply 2 1/4 by 16, which gives you 36

i believe that the slope of the line is -5

step-by-step explanation:

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
