I don’t see a question attached unfortunately
An hourglass is turned over with the top part filled with
sand. after 3 minutes, there are 855 ml of sand in the top half. after 10
minutes, there are 750 ml of sand in the top half. This can be represents a two
points ( 3, 855) and (10, 750) . using this to solve the slope m =
(750-855)/(10-3) = -15. And using one point the equation is y = -15x + 900.
Split the figure into two shapes.
Top rectangle would be 6 feet x 5 feet ( 8-3)
The bottom rectangle would be 2 feet x 3 feet.
Calculate the area of both and add them together:
6 x 5 = 30
2 x 3 = 6
Total area = 30 + 6 = 36 square feet.
