Answer:
Y=40
Explanation:
Due to the nature of both X and Y varying directly, you can view the problem as a proportion. If x=6 and y=30, that must mean that when x=8 y must equal 40.
6:30 = 8:40
or
30/6= 5
Y/8= 5
Because they vary directly they are equivalent, and so multiply 8 by 5 and get 40.
-- The area of the kitchen floor is (11.5 ft) x (9.5 ft) = 109.25 square ft.
-- The area of each tile is (0.5) x (0.5) = 0.25 square ft.
-- If the tiles are carefully placed, with no overlap and no big sloppy spaces
between them, the number of tiles required to cover the floor is
(109.25 ft²) / (0.25 ft²/tile) = 437 tiles .
