1. Caitlin travels for 1 1/3 hours to visit a friend who lives 4 1/2 miles away. Martin travels 4 1/4 miles to visit a friend. It takes him 1 1/5 hours to get there. Who travels
at a greater rate of miles per hour?

susie has 7 apples

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

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
