Carlos martin received a statement from his bank showing a balance of $56.75 as of march 15. his checkbook shows a balance of $87.37 as of march 20. the bank returned all cancelled checks but two. one check was for $5.00 and other was for $13.25. how much did carlos deposit in his account between march 15 and march 20

Checks not cancelled;
5.00+13.25
18.25
Total 

On March 20 he had $87.37 so $87.37-$56.75=$30.62. So between March 15 and March 20 $30.62 was deposited. Since $18.25 was returned to him you would subtract that from $30.62. $30.62-$18.25= $12.37. Therefore, Carlos deposited $12.37 into the account between March 15 and March 20.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
