The employee yearly contribution to the
U.S. Medicare tax on a salary of 40,000 $/year is $580.
Medicare is a federal employment tax that helps pay the Medicare insurance program.
The Medicare duty, occasionally known as the" sanitarium insurance duty," is a civil employment duty that contributes to the Medicare insurance program. Medicare duty, like Social Security duty, is taken from an hand's payment or paid as a tone- employment duty.
Part A of the Medicare program, which covers sanitarium insurance for grown-ups 65 and aged, as well as persons with certain impairments or medical conditions, is funded by the Medicare duty. Medicare sanitarium insurance includes hospitalization, lodge care, nursing home care, and certain home healthcare.
Anyone working in the United States is obliged to pay Medicare levies.

Sphere A has radius 2 cm. Sphere B has radius 4 cm. a) Calculate the volume of each sphere.
Answers
Given the radius of each sphere, the volume of sphere A and B are 33.49cm³ and 267.95cm³ respectively.
What are the volumes of sphere a and b?A sphere is simply a geometrical object with a three-dimensional analogue to a two-dimensional circle.
The volume of a sphere is expressed as;
V = (4/3) × π × r³
Where r is radius and π is constant pi ( π = 3.14 ).
Given the data in the question;
Radius of Sphere A = rA = 2cmRadius of Sphere B = rB = 4cmVolume of each sphere = ?First, we determine the volume of sphere A.
V = (4/3) × π × r³
V = (4/3) × 3.14 × (2cm)³
V = (4/3) × 3.14 × 8cm³
V = 33.49cm³
Hence, the volume of sphere A is approximately 33.49cm³.
Next, we determine the volume of sphere B.
V = (4/3) × π × r³
V = (4/3) × 3.14 × (4cm)³
V = (4/3) × 3.14 × 64cm³
V = 267.95cm³
Hence, the volume of sphere Bis approximately 267.95cm³.

Step-by-step explanation:
Parallel Line:
y = -4x + 1; (6, -1)
(x₁, y₁)
y - y₁ = m (x - x₁)
y - (-1) = -4 (x - 6)

Answers
The inverse of the fuction y = 3 x + 2 is y = x/3 - 2/3.
What exactly is the inverse variation?Inverse variation refers to a relationship between two variables in which the value of one increases while the value of the other decreases.When two quantities, say X and Y, are related in such a way that increasing X causes a decrease in Y and vice versa, this is known as indirect or inverse variation.So,
All we have to do to find the inverse of an equation is switch the variables x and y.
x = 3y + 2Now, solve for y as follows:
3y = x - 2y = x/3 - 2/3Therefore, the inverse of the fuction y = 3 x + 2 is y = x/3 - 2/3.

Answers
The equation of the line y = mx + b can be used to calculate the slope of a line m = ( y₂ - y₁ ) / ( x₂ - x₁ ) that passes through two points.
A line is defined as a curve showing the shortest distance between 2 points.
Here,
The slope of the line passing through two points ( x₁, y₁ ) and ( x₂, y₂ ) is given as :
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
The line that connects two locations has the equation y = mx + b, where m is the slope of the line and b is a constant.
We can find b, using the x, y, and m values in the equation of a line to obtain the y-intercept.
Therefore, the Slope of the line can be given as m = ( y₂ - y₁ ) / ( x₂ - x₁ ) and equation of line y = mx +b.

Answers
After direct variation y = 6/5 when x = 4.
What do we mean when we say "direct variation"?To give the reader a hint, direct variation equations use the same phrase.The phrase could be "directly proportional" or "directly varies."For example, the area of a square is proportional to the square of its side.The variational constant is k = 3 if y varies directly as x and y = 6 when x = 2.As a result, y = 3x is the direct variation equation.So,
The initial statement is y = kx
Then to find y when x = 4.
K constant will be y/x ⇒ 3/10That is y = kx ⇒ y = 4/3 × xWhen x = -3:
y = 3/10 × 4 ⇒ y = 6/5
Therefore, after direct variation y = 6/5 when x = 4.

What is mean by Fraction?
A number expressed as a quotient in which a numerator is divided by denominator is called a fraction.
Given that;
The numbers are 1 5/6 and 3 2/3.
Now, Let us assume original number 'x'.
Change mixed fraction into improper fraction,
1 5/6 = 11/6
3 2/3 = 11/3
Then by the given condition,
Subtracting 7/18 from x and add 11/6, we get;
x - 7/18 + 11/6
And this is equal to = 11/3
So, we get;
x - 7/18 + 11/6 = 11/3
Add 7/18 both side,
x - 7/18 + 11/6 + 7/18 = 11/3 + 7/18
x + 11/6 = 11/3 + 7/18
Subtract 11/6 both side,
x + 11/6 - 11/6 = 11/3 + 7/18 - 11/6
x = 11/3 + 7/18 - 11/6
x = 66/18 + 7/18 - 33/18
x = 40/18
x = 20/9

How much was in her account at the end of the month?
Answers
Sarah have $495 in her account at the end of the month.
Given,
The amount Sarah had in her bank account at the beginning of the month = $600
The deposits she made within the month = $40 and $25
The withdrawals she made = $100, $50 , $20
We have to find the balance amount in Sarah's account after all these transactions made:
The deposits Sarah had = 600 + 40 + 25 = 665
Sarah had $665 in her account in a month.
Withdrawals made by Sarah = 100 + 50 + 20 = 170
Sarah made a total withdrawal of $170 in the month.
Now, we have to find the account balance of Sarah:
