Kareem heats a beaker of water to a boil. Then he records that the water temperature decreases from 100°C to 19°C in 5 and 2/5 minutes. What was the change in temperature each minute? Enter your answer in the box.

Step-by-step explanation:

2/5min=24 sec

5 min=300 sec

total=324 seconds

the water decreased 100-19=81 degrees

81/324=0.25 degrees/second

the change in temperature was 0.25 degrees per second

we will multiply by 60

15 degrees per minute

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

because they could drop even lower..
