The associative property lets you move the parentheses.

6. (-20×50)×-29 = -1000×-29 = 29,000

7. (5×10)×18 = 50×18 = 900

8. 400 + (60 + 98) = 400 +158 = 558

9. 3×(20×5) = 3×100 = 300

10. (18 + 9) +91 = 27 +91 = 118

Your annual salary is $28,460 your State personal deductions total $88 for a weekly pay period. The state tax rate is 3.6% of ta
miv72 [106K]

Answer:

First, in one year you win:

$28,460

Now yearly we can subtract:

3.6% for the taxable income

1.7% for the gross pay:

(Those apply to the complete annual salary)

3.6% + 1.7% = 5.3%

This in decimal notation is 0.053, then paying those two things we have left:

$28,460*(1 - 0.053) = $26,951.62

Now we need to subtract the union dues, which are $156 per year.

$26,951.62 - $156 = $26,795.62

Now, this is yearly, and we want to know the weekly pay.

In one year we have 365 days.

One week has 7 days.

Then in one year, we have:

365/7 = 52.14 weeks.

Then the pay per week is:

$26,795.62/52.14 = $513.92

And now, each week we must pay $88 for state personal deductions, and $67 for FIT.

Then we have:

$513.92 - $88 - $67 = $358.92

Then the net pay for each weekly pay period is: $358.92

Point WW is located at (6,4)(6,4) on the coordinate plane. Point WW is reflected over the yy-axis to create point W'W ′ . Point
yKpoI14uk [10]

Using translation concepts, the ordered pair that describes the location of W'' is: W''(-6,-4).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a reflection over the y-axis is:

(x,y) -> (-x,y).

Hence:

W'(-6,4).

The rule for a reflection over the x-axis is:

(x,y) -> (x, -y).

Hence:

W''(-6,-4).
