kifflom [539]

Answer:

<h2> Assuming your friend said the temperature over there was   68 degrees Fahrenheit  in degrees C it would be 20 °C</h2>

Step-by-step explanation:

The question is not complete, as the information, your best friend in Europe about the temperature over there is missing, nevertheless, we can proceed with this problem by plugging in an assumed temperature.

The expression for conversion from degrees F to degrees  C is given as

T(°C) = (T(°F) - 32) × 5/9

Now say temperature your friend e-mailed you is 68 degrees Fahrenheit (you can as well plug in your own value)

T(°C) = (68°F - 32) × 5/9

T(°C) = (36) × 5/9

T(°C) = 180/9 = 20 °C

T(°C)  = 20 °C

vodka [1.7K]

Answer:

63%

Step-by-step explanation:

<em>From the question, we aim to find the percent increase in the tuition</em>

Given data

initial cost= $99 per credit hour

Final cost=  $268 per credit hour

% increase= (Final - initial )/initial *100

substitute

% increase= (268- 99 )/268 *100

% increase= 169 /268 *100

% increase= 0.630*100

% increase= 63%

Hence the increase in the tuition from 1990 to 2003 is 63%
