Answer:
7.8%
Step-by-step explanation:
● To do this, you need to multiply 6.75 by 21 to find out how many meters are in all. 6.75×21 is 141.75
● Next you multiply 141.75 by 2 to see how much it costs which is 283.5
● Since we're dealing with money, it would have two place values so we add a zero and we get $283.50
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.
