Ahuman chain is formed by 60 people standing with their arms outstretched, each holding the hand of the person on either side. the first 30 people in the chain have arm spans of 6 feet. the next 30 people have arm spans of 5.5 feet. at the word "go! " the first person squeezes the hand of the second person. then the second person squeezes the hand of the third, and so on. assume that each person takes 1/3 second to pass along the signal. what piecewise function correctly models the distance that the signal travels in t seconds?

Can someone me and do the problem plz so i can understand it more better

Give all possible names for the line shown.calculation tip: lines can be written with either point first.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
