A man has 10 more dimes than quarters. he has $2.75 how many of each coin does he have?

5 quarters, 15 dimes.

Step-by-step explanation:

5 quarters, 15 dimes

q + 10 = d

0.25q + 0.1d = 2.75

0.25q + 0.1(q + 10) = 2.75

0.25q + 0.1q + 1 = 2.75

0.35q = 1.75

q = 5

Check:

0.25(5)+ 0.1(15)= 2.75

1.25 + 1.5 = 2.75

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
