Every day kianna practices softball and piano each day she practices for 2 hours if after 7 days she practiced both softball and piano for a total of 24.5 hours how many hours per day did kianna ptactice piano

1.5 hours

Step-by-step explanation:

Softball was practiced for 2 hours each day.

After 7 days she must have practiced it for;

= 7 * 2

= 14 hours

She practiced both piano and softball for a total of 24.5 hours. She therefore practiced piano for;

= 24.5 - 14

= 10.5 hours

If in 7 days she practiced piano for 10.5 hours, everyday she must have practiced piano for;

= 10.5/7

= 1.5 hours

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
