Answer:

t = 17.5 f = 12

Step-by-step explanation:

If <em>MNOP </em>is a square, you know that each angle is going to be 90°. To solve, let's first set each equation equal to 90°:

90 = 4t + 20

and

90 = 7f + 6

Then solve both equations:

90 = 4t + 20 \\ 70 = 4t \\ 17.5 = t

and

90 = 7f + 6 \\ 84 = 7f \\ 12 = f

I hope that helps!

How much would you need to deposit in an account now in order to have $4000 in the account in 10 years? Assume the account earns
gogolik [260]

Answer:

  $2355.06

Step-by-step explanation:

Use the compound interest formula, filling in the numbers you know. Then solve for the number you don't know.

  A = P(1 +r/n)^(nt)

where A is the account balance, P is the amount invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

Filling in the given values, we have ...

  4000 = P(1 +.053/52)^(52·10) = P(1.6984738)

  P = 4000/1.6984738 ≈ 2355.06

You would need to deposit $2355.06 in order to have $4000 in 10 years.
