Chapter R.2, Problem 99PE

Use the freezing and boiling points of water to find a formula expressing Celsius temperature C

Find the equivalant Celsius reading for a temperature of 95 degrees F

A thermometer reading 75°F is taken out where the temperature is 20°F. The thermometer reading is 30°F, 4 minutes later. Find the time (in minutes) taken for the reading to drop from 75°F to within half degree of the air temperature. 11.03 minutes

Use Cramer's Rule to solve (if possible) the system of linear equations. (If not possible by Cramer's Rule, enter IMPOSSIBLE.) X1 + 2x2 = 10 X + X = -1 STEP 1: Find the coefficient matrix. A = STEP 2: Find A,. A = STEP 3: Find A2. A2 =

Which is greater, an increase of 10° Fahrenheit or an increase of 10° Celsius? Justify your answer. 10° Celsius, because each degree Fahrenheit is equivalent to 1.8° Celsius. 10° Fahrenheit, because each degree Celsius is equivalent to 1.8⁰ Fahrenheit. 10° Celsius, because each degree Celsius is equivalent to 1.8° Fahrenheit. 10° Fahrenheit, because each degree Fahrenheit is equivalent to 1.8° Celsius.

AE %3= EC% D

5 Convert the given Fahrenheit temperature to its equivalent temperature on the Celsius scale. Use C=(F-32) or 9 F ==C+32, where F is the degrees in Fahrenheit and C is the degrees in Celsius. 76°F 76°F = °C (Round to the nearest tenth as needed.) W

During a 12-hour period, the temperature in a city dropped from a high of 63°F to a low of −29°F. What was the range of the temperatures during this period? __________°F

A thermometer reading 75° F is placed in an oven preheated to a constant temperature. Through a glass window in the oven 1/2013 -minute and 140° F after 1 minute. How hot is the oven? door, an observer records that the thermometer reads 110° F after- OF
