The temperature of liquid in an experiment starts at 0*C. The experiment calls for the temperature of the liquid to change at a rate of -0.60*C per minute. How long will it take for the liquid to reach -10.5*C

The liquid will take 17.5 minutes to reach -10.5 ºC.

Step-by-step explanation:

From this statement we understand that the temperature of liquid is increased at constant rate in time, whose model is described by:

(Eq. 1)

Where:

- Temperature of the liquid, measured in degrees Celsius.

- Heating rate, measured in degrees Celsius per minute.

- Time, measured in minutes.

- Initial temperature, measured in degrees Celsius.

If we know that   and , the temperature model for the liquid is:

(Eq. 2)

In addition, if , then time taken for the liquid to reach that temperature is:

The liquid will take 17.5 minutes to reach -10.5 ºC.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
