Wendy can ride her bike 0.8 miles in 6 minutes how many miles can she ride her bike in 2.5 hours

20 miles

Step-by-step explanation:

Set up a proportion...

0.8 miles is to x miles as 6 mins is to 2.5 hours

*You need to convert 2.5 hours into minutes first, since the first part is in minutes.  There are 60 minutes in an hour, so there are 60(2.5) = 150 minutes in 2.5 hours

0.8/x = 6/150

Now solve for x by cross multiplying...

0.8(150) = 6x

    120 = 6x

       20 = x

She can ride 20 miles in 2.5 hours

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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
