Kareem heats a beaker of water to a boil. then he records that the water temperature decreases from 100°c to 19°c in 525 minutes. what was the change in temperature each minute? enter your answer in the box. °c

Temperature of water in beaker decreased at rate of per minute.

Step-by-step explanation:

We are given:

Now we will divide change of temperature by 525 minutes to find change in temperature of water per minute.

Therefore, temperature of water decreased at rate of per minute.

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
