Alana practiced dancing for 11 −−4 hours on monday, 19 −−8 hours on wednesday, and 2.6 hours on friday. on which day did she practice the closest to 2 hours? explain your reasoning.

Time taken to practice dance on Monday = hours

In decimals it is 1.25 hours

Time taken to practice dance on Wednesday = = or in decimal form it is 2.125 hours

Time taken to practice dance on Friday = 2.6 hours

Now comparing all the values in hours that is 1.25 , 2.125 and 2.60 ,the closest number to 2 is 2.125

1.25 is 35 minutes less than 2.

2.60 is greater far and from 2.

And 2.125 is closest to 2.

Hence, she practiced closest to 2 hours on Wednesday.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
