Answer:

A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

To answer this problem, suppose an amount n.

After a year in value of the investment is:

0.84n

Now we calculate the rate of change of n with the following formula:

V = \frac{Final\ Amount - Initial\ Amount}{Initial\ Amount}

V = \frac{0.84n-n}{n}*100\%\\\\V = \frac{n(0.84-1)}{n}*100\%\\\\V = (0.84-1)*100\%\\\\V = -0.16 * 100\%\\\\V = -16\%

The value of the investment decreased by 16% with respect to the initial amount.

The correct answer is the option

A. The value of his investment decreased by 16% during this time period.

Answer:

a=21

AB=23.9

BC=19.5

CD=(23.9)

AD=19.5

Step-by-step explanation:

Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:

a-1.5=19.5

add 1.5 to both sides

a=21

now substitute 21 in for a in each equation.

AB=CD so

AB=23.9

BC=AD so

BC=19.5

CD=(21)+2.9 so

CD=(23.9)

AD is given so

AD=19.5

Change each into decimal

0.5 = 0.5

1/5 = 0.2

0.35 = 0.35

12/25 = 0.48

4/5 = 0.80

Set in order from least to greatest.

0.2, 0.35, 0.48, 0.5, 0.80

1/5, 0.35, 12/25, 0.5, 4/5 is your order.
