The temperature drops -9/10 every hour how much will it change in 3/2 hours

0.45

Step-by-step explanation:

Ok so you start with -0.9. You need to find how much it will change in an hour and 30 minutes. So you subtract -0.9 from -0.9 and you'd get 0. Now, we have to subtract half of -0.9 (because 30 minutes is half an hour). Half of -0.9 is -0.45. Subtract 0 by -0.45 and you get 0.45.

It varies 0,45. For 1,35 - 0,9 = 0,45

Step-by-step explanation:

-9/10 = -0,9

3/2 = 1,5

1h       -9/10

1,5h   x

x = 1,5 * -0,9

x = -1,35

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
