The price of an article on sale was 80% of the regular price. if the sale price was $56, what was the regular price?

regular price = 70

Step-by-step explanation:

you are paying 80 percent of the regular price

regular price * 80 percent = new price

regular price * .8 = 56

divide by  .8 on each side

regular price *.8 /.8 = 56/.8

regular price = 70

answer: h

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
