Hey there! :D

Remember that the question said estimate.

So

47% rounds to 50%

.5 and 1/2 are equal to 50%

89 rounds to 90.

You could say that:

1/2*90

0.5*90

90/2

These will all work and will give you the same answer.

I hope this helps!

A circle whose center is at (3,-5) has equation

Llana [10]

Answer: a = 10

radius = 7

Step-by-step explanation:

The generic equation for a circle of radius R is, centered in the point (a, b)

(x - a)^2 + (x - b)^2 = R^2

In this case, we know that the center is (3, -5)

Then the equation of the circle must be something like:

(x - 3)^2 + (y + 5)^2 = R^2

And we have:

x^2 + y^2 - 6*x + a*y = 15

First, let's complete squares for x:

(x - 3)^2 = x^2 + 2*(-3)*x + (-3)^2 = x^2 - 6*x + 9.

Then we can add 9 to both sides of the equation to get:

x^2 + y^2 - 6*x + a*y + 9 = 15 + 9

(x^2 - 6*x + 9) + y^2 + a*y = 24

(x - 3)^2 + y^2 + a*y = 24

Now let's do the same for y:

(y + 5)^2 = y^2 + 2*5*y + 5^2 = y^2 + 10*y + 25

From this we can already see that a must be equal to 10, if we replace a by 10, the circle equation becomes:

(x - 3)^2 + y^2 + 10*y = 24

Now we can add 25 to both sides of the equation to get:

(x - 3)^2 + y^2 + 10*y + 25 = 24 + 25

(x - 3)^2 + (y + 5)^2 = 49

An the radius of the circle will be equal to:

r = √49 = 7

Assume a tax rate of 6.2% on $128,400 for Social Security and 1.45% for Medicare. No one will reach the maximum for FICA. Comple

Yakvenalex [24]

Answer:

FIT: $340.76 (see comment)
OASDI: $173.60
Medicare: $40.60
Net Pay: $2245.04

Step-by-step explanation:

In addition to the information given in the problem statement, we need to know the applicable tax rates and allowance deductions. If we assume the tables we found (attachments 1 and 2) are the same as those in your text, the one additional fact needed is the gross pay to date. At the given wage rate, paychecks after the 44th week will have reduced FICA tax deductions.

Allowances: 4 × $79.80 = $319.20

Adjusted gross pay for FIT: $2800 -319.20 ≈ $2481 (rounded to nearest $)*

FIT: 0.22 × (2481 -1711) +171.36 = 0.22×2481 -205.06 = 340.76

Social Security & Medicare: 0.0765 × 2800 = 214.20

Net pay = $2800 -340.76 -214.20 = $2245.04

_____

<em>* Comment on rounding</em>

The IRS gives the option of rounding the pay or the tax, as long as it is consistently done. Here, the amount of tax on the unrounded gross pay would be 4 cents less: 340.72. The option of reducing the last digit of pay to zero is also offered. FIT on 2480 would be 340.54.
