Question

During a science experiment, Faye recorded the temperature of a solution as it cooled in a controlled environment for 6 minutes. She graphed the change in temperature as shown below.

Answer 1

If the solution continues to cool at the same rate, how many minutes will it take for the temperature to cool to 0°C?

24

19

14

9

Answer 2

Answer 4

How do they want you to solve this? (graphing, algebra, estimation?) Can you use a calculator?

Answer 5

yea a calculator

Answer 6

its A

Answer 7

right

Answer 8

Sorry I was drawing a graph...

Answer 9

Oh sorry, it should say right three MINUTES not days.
And yes if you solve

0 = (-5/3)x + 40 add (5/3)x to both sides
(5/3)x = 40 multiply both sides by (3/5)
x = 40*(3/5)
x = 24 minutes

So you're correct. :)
