Is there a triangle whose sides have lengths 12.2 cm, 6.8 cm and 6.5 cm. If not . Why?

yes

Step-by-step explanation:

For the given sides to form a triangle.

The sum of any 2 sides must be greater than the third side.

12.2 + 6.8 = 19 > 6.5

12.2 + 6.5 = 18.7 > 6.8

6.8 + 6.5 = 13.3 > 12.2

Thus the 3 given sides form a triangle

Step-by-step explanation:

F=1.8C+32 is the formula needed to convert a temperature in degrees C to the equivalent temperature in degrees F.  Use it.

Example:  Suppose that C = 27.  What would the equivalent temperature in degrees F be?

Substitute 27 for C in  F=1.8C+32.  We get F=1.8(27)+32 80.6 degrees F.

 27 degrees C is equivalent to 80.6 degrees F.
