Ga person leaves home and walks 4 miles west then 3 miles southwest how far from home is she

Here we should use Pythagoras' Theorem: c^2 = a^2 + b^2, where a and b are the lengths she's walked and c is the distance from her house (it may help to draw a diagram)

c^2 = 4^2 + 3^2
c^2 = 16 + 9
c^2 = 25
c = 5, therefor she is 5 miles away from her home

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
