Step-by-step explanation:

Answer:

B

Step-by-step explanation:

From annual salary of 42,600, we have to subtract the following percentages:

Social Security:

0.062 * 42,600 = 2641.2

Medicare:

0.014 * 42,600 = 596.4

State Income Tax:

0.03 * 42,600 = 1278

Federal Income Tax:

0.13 * 42,600 = 5538

Total Deductions (from percentages) = 2641.2 + 596.4 + 1278 + 5538 = 10053.6

Now, remaining salary:

42,600 - 10053.6 = 32546.4 (annual)

Divided by 12 to get monthly:

32546.4 / 12 = 2712.2 (monthly)

Now, monthly deductions are:

260 + 280 = 540

Net Salary: 2712.2 -  540 =2172.2

Based on the information given his monthly net paycheck is: b. $2172.20.

Deduction

Social security=42,600×62%

Social security = 2641.2

Medicare=42,600×1.4%

Medicare = 596.4

State Income Tax= 42,600×3%

State Income tax = 1278

Federal Income Tax=42,600×13%

Federal Income Tax = 5538

Total Deductions = 2641.2 + 596.4 + 1278 + 5538

Total deduction= 10053.6

Net paycheck:

Net paycheck=(42,600 - 10,053.6)/12- (260 + 280)

Net paycheck=32,546.4/12-540

Net paycheck= 2712.2 -  540

Net paycheck=$2172.2

Therefore, his monthly net paycheck is: b. $2172.20.

Distributive Property.

Step-by-step explanation:

First you solve for the first equation by multiplying 2 by 18 which is 36. Then 3 times 18 which is 54. Then you add them together to get 90.

Next you solve for the second equation by multiplying 5 by 18 which is 90.

Both of these equations are solved by the distributive property because your distributing the number outside of  the parenthesis.

f(–2) = 1

Solution:

The table represents a function.

            x               f(x)

           –6               3

           –2                1

             0                4

             3               –2

To find the value of f(–2):

f(–2) means the value of f(x) for the corresponding x value –2.

In the table, if the x value is –2, then f(x) is 1.

See the value of f(x) which correspond to x = –2.

Hence f(–2) = 1.

Answer:

Reflexive

Step-by-step explanation:

The reflexive property of equality says that a given real number is always equal to itself.

For example :

[tex]y = y[/tex]

[tex]a = a[/tex]

[tex]b = b[/tex]

[tex]5 = 5[/tex]

are all examples of reflexive properties of equality.

[tex]4 + 9 = 4 + 9[/tex]

can be simplified to

[tex]13 = 13[/tex]

Which is explains why it is the reflexive property.

N = N₀* [tex](\frac{1}{2} )^{\frac{t}{h} }[/tex]

where N is how much you currently have

N₀ is the starting amount

t is the time

and h is the half life of the substance.

The half-life formula for a radioactive isotope is amount remaining = (amount initial) × e^(-t/t1/2), where e is the base of natural logarithms, t is the elapsed time, and t1/2 is the half-life of the isotope. The variables t and t1/2 must have the same units of time. The formula can be used to calculate how much of a radioactive isotope remains after a certain amount of time.

The half-life formula for a radioactive isotope is given by:

amount remaining = (amount initial) × e^(-t/t1/2)

Here, e is the base of natural logarithms (approximately 2.71828182), t is the elapsed time, and t1/2 is the half-life of the isotope. The variables t and t1/2 must have the same units of time. To evaluate the exponential function, you may need to use a calculator or an inverse logarithm function. It is important to note that the length of time t does not need to be an exact multiple of half-lives.

The wise man's age can be calculated by solving the equation 400 - 3x= 244, leading to the solution that he is 52 years old.

To determine the wise man's age, we need to set up an equation based on the given statement:

Let's call the wise man's age x

The statement says, "400 reduced by 3 times my age is 244." This can be written as:

400 - 3x = 244

To find x, follow these steps

400 - 3x = 244

3x = 400 - 244

3x = 156

x = 156 / 3

x = 52

So, the wise man is 52 years old.

Answer:

330 degrees

Step-by-step explanation:

a full rotation is 360 degrees and if you subtract 30 from 360 its 330

Final answer:

To complete a full rotation, Greg's ceiling fan, which has already rotated 30 degrees, needs to rotate one more time, as there are 330 degrees left to reach 360 degrees, which is a full rotation.

Explanation:

Greg's ceiling fan rotates 30 degrees and stops. To determine how many more times the fan needs to rotate to complete a full rotation, first, we need to know that one full rotation is equal to 360 degrees. As the fan has already rotated 30 degrees, we subtract this from 360 degrees:

360 degrees - 30 degrees = 330 degrees.

Now, because one full rotation is 360 degrees, we divide the remaining degrees by 360 to find the number of additional rotations needed:

330 degrees / 360 degrees per rotation = 0.9167 rotations.

Since a fan cannot complete a fraction of a rotation in terms of action, Greg's ceiling fan would need to rotate one more time to make it a complete rotation.

Step-by-step explanation:

1) Given quadratic expression is [tex]x^2-2x+2[/tex]

First equate the given expression to zero then we will find the roots.

Since the given equation is quadratic hence it has two roots.

For the quadratic equation we have that [tex]ax^2+bx+c=0[/tex]

Therefore roots [tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex] here a and b are coefficients of [tex]x^2andx[/tex] respectively and c is a constant

[tex]x^2-2x+2=0[/tex] here a=1 ,b=-2 and c=2

Now Substitute the values in [tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex] we get

[tex]x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(2)}}{2(1)}[/tex]

[tex]=\frac{2\pm \sqrt{4-8}}{2}[/tex]

[tex]=\frac{2\pm \sqrt{-4}}{2}[/tex]

[tex]=\frac{2\pm \sqrt{4i^2}}{2}[/tex]

[tex]=\frac{2\pm2i}{2}[/tex]

[tex]=2(\frac{1\pm i}{2})[/tex]

[tex]x=1\pm i[/tex]

Therefore [tex]x=1+i[/tex] and [tex]x=1-i[/tex] are the roots of the given quadratic equation.  

2) Given that the number 16 has four roots.In other words, there are four complex numbers that can be entered in the square .

Let x be the given number 16

i.e., x=16

[tex]=2^4i^4[/tex] ( by using the formula [tex](ab)^m=a^mb^m[/tex] )

[tex]=16(1)[/tex] ( by [tex]i^2=-1[/tex] and [tex]i^4=(i^2)^2=(-1)^2=1[/tex] )

[tex]x^4=16=(2i)^4[/tex]

Therefore [tex]x^4=(2i)^4[/tex]

Since powers are same we can equate the bases ( bases are equal )

Therefore x=2i,2i,2i,2i are the roots of the given number 16 and they are complex numbers too

Answer:

Janet has coins worth 252.5, 101, and 50.5.

Step-by-step explanation:

Let us call the three coins [tex]a,b[/tex], and [tex]c[/tex].

The first coin [tex]a[/tex] is 5 times another coin (let's say [tex]b[/tex]); therefore,

[tex]a = 5b[/tex],

and the third coin is 2 times the value of another coin (it's coin [tex]b[/tex]):

[tex]c =2b[/tex].

The total worth of all coins is 404; therefore,

[tex]a+b+c =404[/tex]

or

[tex]5b+b+2b =404[/tex]

[tex]8b =404[/tex]

[tex]\boxed{b = 50.5}[/tex]

with the value of [tex]b[/tex] in hand, we find [tex]a[/tex] and [tex]c[/tex]:

[tex]a = 5b = 5(50.5)[/tex]

[tex]\boxed{a = 252.5}[/tex]

and for [tex]c:[/tex]

[tex]c = 2 b = 2 (50.5)[/tex]

[tex]\boxed{c = 101}[/tex]

Thus, Janet has 3 coins worth 252.5, 101, and 50.5.

Answer:3xy

Step-by-step explanation:18x^2y^3= 3,6,x,x,y,y,y

6xy^2=. 3,2,x,y,y

3x^3y=. 3,x,x,x,y

All three have this in common a 3xy

The greatest common factor of the given polynomial's terms 18x^2y^3-6xy^2+3x^3y is 3xy. This is determined by factoring each term, and finding the greatest factor that occurs in all of the lists.

In mathematics, the greatest common factor (GCF) of a set of terms in a polynomial, is the largest term that divides each term exactly. To find the greatest common factor for the given polynomial 18x^2y^3-6xy^2+3x^3y, first, we list the factors for each term.

The term 18x^2y^3 factors as 2*3*3*x*x*y*y*y, the term -6xy^2 factors as -2*3*x*y*y, and the term 3x^3y factors as 3*x*x*x*y.

The greatest factor that occurs in all three lists is 3*x*y, so 3xy is the greatest common factor of the polynomial’s terms.

Step-by-step explanation:

Step 1:  Convert words into an expression

0.45 plus 9x equals 27

0.45 + 9x = 27

Step 2:  Solve for x

0.45 + 9x - 0.45 = 27 - 0.45

Mercury's distance = 5.8 x 10¹⁰

Venus' distance = 1.86 farther or more than Mercury's, namely 1.86(5.8 x 10¹⁰)

[tex]\bf \stackrel{\textit{venus' distance}}{1.86(5.8\times 10^{10})}\implies \begin{cases} 1.86(58000000000)\\ 107880000000\\ 1.0788\times 10^{11} \end{cases} \\\\\\ \stackrel{\textit{earth's distance}}{2.58(5.8\times 10^{10})}\implies \begin{cases} 2.58(58000000000)\\ 149640000000\\ 1.4964\times 10^{11} \end{cases}[/tex]

about how many meters farther is Earth's than Venus?  well, we can simply get their difference, we know the Earth is farther than Venus, so we can just subtract Venus' distance from Earth's to get the difference, namely 149640000000 - 107880000000.
