Answer:

A = 145cm

Step-by-step explanation:

A+B+C = 445cm  

b = 1/2c

a = b+45  =  1/2c + 45

445 = c + (0.5c) + (0.5c + 45)

445 = 2c + 45

445 - 45 = 2c

400/2 = c

c = 200cm

a = 1/2c + 45 = 1/2*200 + 45 = 100 + 45 = 145cm

how much must you deposit in an account that pays 8% interest,compounded monthly to have a balance of $1000 after three years?​
NNADVOKAT [17]
<h3>Answer:  787.25 dollars</h3>

=============================

Work Shown:

A = final amount after t years = 1000

P = initial deposit = unknown

r = interest rate in decimal form = 0.08

n = compounding frequency = 12

t = number of years = 3

-----

A = P*(1+r/n)^(n*t) is the compound interest formula

1000 = P*(1+0.08/12)^(12*3)

1000 = P*1.27023705162066

1.27023705162066P = 1000

P = 1000/1.27023705162066

P = 787.254629932364

P = 787.25 rounding to the nearest penny

----

note: this assumes that the interest rate stays at 8% the entire three year period; also, you cannot withdraw any money from the account during this time period.
