kirza4 [7]

Answer:

5,562 x $10^{-6}$

Step-by-step explanation:

Firts, we need to find the maximum recommended amount of bluefish per month. Since the FDA recommends 3 servings of 6.00 oz each, the maximum amount would be:

the maximum amount of bluefish per month = $3 * 6.00 oz = 18.00 oz$

Since bluefish contains 0.309 ppm of mercury per 1x $10^{6}$ oz of fish, then:

0.309 oz mercury --------> 1x $10^{6}$ oz of fish

How many ( $y$ ) --------> 18.00 oz of fish

$y = \frac{18.00 oz of fish * 0.309 oz of mercury}{1 x 10^{6} oz of fish } = 0.000005562 = 5.562 x 10^{-6}$ oz mercury

If a person lnvests $120 at 8% annual interest, find the approximate value of the investment at the end of 5 years

Pie

Answer:

$176.3193692 or $176.32 (rounded to two decimal places)

Step-by-step explanation:

It is a compound interest, which means the interest accumulates on an initial amount each period.

The formula is A=P(1+R)^n

A= the total amount P=initial amount R=rate n=time (years)

P=$120 Rate= 8% or 0.08 (decimal) n=5 (years)

A=120 (1+0.08)^2

A=120 (1.469328077)

A= 176.3193692
