1. Mark opened a bank account with $50 and added $25 each month. Tony opened a bank
account the same day with $75 and added $20
each month. In how many months will they
have the same amount of money?

5 months

Step-by-step explanation:

Tony starts with 25 more dollars than Mark. Every month he gets 5 dollars.

25/5 = 5 months.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
