50°F is how many °C?
-10 |
|
122 |
|
10 |
|
58 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
The envelope of gases surrounding the planet is called the:
lithosphere |
|
hydrosphere |
|

|
geosphere |
The biosphere is the global ecological system integrating all living beings and their relationships.
