For his science experiment, Julio placed a pan of water in his refrigerator to see how long it would take to evaporate.  After 2 days, there was 280 ml of water in the pan, and after 4 days, there was 240 ml of water in the pan.  In his report, he noted that the same amount of water evaporated each day.

How many milliliters of water was in the pan to start?​ ​ (a)   ​

At this rate, how many days until no water remains in the pan? ​ (b)  

• 320 ml
• 16 days
• 520 ml
• 240 ml
• 280 ml
• 2 day
• 6 days
• 8 days

The relationship between the Fahrenheit (F) and Kelvin (K) scales for measuring temperatures can be represented by a linear function.  A temperature of 68°F corresponds to 293.15°K, and a temperature of 185°F corresponds to 358.15°K.

Which statement is the best interpretation of the slope?

• A temperature of 0°K corresponds to -459.67°F.

• A temperature of 0°F corresponds to 255.37°K.

• For each change of one degree in the Fahrenheit scale, there is a change of 5/9 degrees in the Kelvin scale.

• For each change of one degree in the Fahrenheit scale, there is a change of 9/5 degrees in the Kelvin scale.
