8/9=4/5k how to solve

1 answer:

5 0

Divide both sides by 4/5 or multiply by the reciprocal.

Flip 4/5 to get the reciprocal.
The reciprocal of 4/5 is 5/4 so we will multiply both sides by that.

5/4 * 8/9 = 4/5 * 5/4 * k

4/5 and 5/4 cancel out so now you have

5/4 * 8/9 = k

multiply top and bottom
(5 *8 )/(4*9)

40/36

Simplify

10/9

g100num [7]

Answer:

$24,498,509.74

Step-by-step explanation:

The formula for the value as a function of time is ...

V(t) = P·e^(rt)

Filling in the numbers and doing the arithmetic, we have ...

V(35) = 3,000,000·e^(0.06·35) ≈ 24,498,509.74

Compounded continuously for 35 years, the investment will be worth $24,498,509.74.
