A boat travels due north for 20km and then turns and travels due east for 7km. How far away is the boat from where it started?

21

Step-by-step explanation:

+ =

(20)^2 + (7)^2 =

400 + 49 =

c= = 21.1 ~ 21

(hope its right)

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
