On Monday, Sandra set a goal to run 2 1/2 miles by Thursday . She ran 1/3 of a mile on Monday, 5/8 of a mile on Tuesday, and 7/12 of a mile on Wednesday. How many miles should she run on Thursday to reach her goal? Express your answer as a fraction in lowest terms.

23/24

Step-by-step explanation:

I found a common denominator of 24, and then multiplied the numbers so that they would equal the common denominator. I then added all of the numbers up, to get an answer of 37/24. Finally, I subtracted 2 12/24 (which is equal to 2 1/2) to get an answer of 23/24. Because that cannot be simplified, that would be your final answer. Hope this helps :)

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
