Donna plans to put her graduation money into an account and leave it there for 4 years while she goes to college she receives $850 in graduation money that she puts into an account that earns 5% interest and not equally how much will be in donna's account at the end of the four years

her account will have 1,020 dollars if it is a 5% annual interest rate

Step-by-step explanation:

850        

___  =    ___            (cross multiply)

100          5

when you cross multiply you get that 5% is 42.50

multiply 42.50 by 4 (the number of years the money will be in the account)

add that number to the original amount and you get the total after 4 years.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

why can't you?
