Luce is single and making $763 biweekly. She claims no federal withholding allowances. If the state tax is 19% of the federal tax, how much in state tax does Luce contribute? a.
$12.92
b.
$15.13
c.
$15.77
d.
$16.34

Answers

Answer: d. $16.34

Step-by-step explanation:

The table shows that if the wages are between 760 and 780 and there are no withholding allowances, the federal tax is $86.

Luce therefore has a federal tax of $86 as she falls in the bracket described.

If state tax is 19% of this, state tax is:

= 19% * 86

= $16.34

The amount of state tax which is contributed by the Luce for the no federal withholding allowances is $16.34.

What is federal income tax?

Federal income tax is the tax which is used to develop and run the city or country and charged on the citizen residing there  .

A 9-column table with 7 rows is given in the prooblem.

Luce is single and making $763 biweekly. She claims no federal withholding allowances.

This amount is come between the values of $760 and $780.  If we look into the table provided into the problem, the federal tax for this slab is $86.  

Now the state tax is 19% of the federal tax. Thus, the 19 percent of the federal tax $86 is,

[tex]\rm tax=86\times\dfrac{19}{100}\\tax=16.34[/tex]

Thus the amount of state tax which is contributed by the Luce for the no federal withholding allowances is $16.34.

Elena paga por su recibo de teléfono S/. 132,80 y de luz S/. 75,20. Si 3 meses del año pagó igual. ¿Cuánto pagó por este tiempo?

Answers

Answer:

Por 3 meses Elena pagó $624.

Step-by-step explanation:

Elena paga por su recibo de teléfono $ 132,80 y de luz $ 75,20. Por lo que, para obtener lo pagado por Elena en ese mes por sus recibos se debe sumar ambos importes:

132,80 + 75,20= 208

Entonces en ese mes Elena pagó $208.Si 3 meses del año pagó el mismo importe, entonces debes multiplicar $208 por 3.

208*3= 624

Entonces, por 3 meses Elena pagó $624.

Consider function h. Complete the statements describing the y-values of function h.

1. The end behavior of function h is described by (an oblique, no, or absolute) asymptote.
2. The range of function h is all y-values (less than or equal to 4,1,-4, or 0) and (greater than 1, 0, -4, or 4)

Answers

Answer:

1) The end behavior of function [tex]h[/tex] is described by an absolute (horizontal) asymptote.

2) The range of function [tex]h[/tex] is all y-values less than or equal to 0 and greater than 1.

1) The end behavior of the function is defined by a horizontal asymptote, that is the values of [tex]y[/tex] when [tex]x[/tex] tends to [tex]\pm \infty[/tex]. Answer: The end behavior of function [tex]h[/tex] is described by an absolute (horizontal) asymptote.

2) The range of the function is the set of values of [tex]y[/tex] associated with the function.

Answers

Answer:

He paid $640 out of his total $3,200 for the month.

As a fraction it is (640/3200) which equals (1/5)

We want it as a percentage so we multiply the fraction by 100.

1/5×100=20%

20% is the final answer.

Answer:

y = -13

Step-by-step explanation:

y = 3x - 1             equation(i)

2x - y = 5            equation(ii)

now substitute the value of y in equation(ii)

2x - y = 5

2x - (3x -1) = 5

2x - 3x + 1 = 5

-x = 5 -1

-x = 4

x = -4

again substitute the value of x in equation (i)

y = 3x - 1

y = 3*-4 - 1

y = -12 - 1

y = -13

Ramesh went from place A to place B and then from place B to place CA is 10.8 km from B and place B is 15.5 km from place C, Rahul went from place A to place D and then place D to place C, distance between place A and D is 11.7 km and distance between place D and place C is 18.2 km, Who travelled more distance and by how much, also calculate the total distance between place A and place D and express the total distance in M,CM and KM.​

Answers

Answer:

Part A

Rahul by 3.6 km

Part B

The distance between A and D, through place C, d are;

The distance between A and D in meters, m = 44,500 m

The distance between A and D in centimeters, cm = 4,450,000 cm

The distance between A and D, in kilometers, km = 44.5 km

Step-by-step explanation:

Part A

The details of the journeys are;

The distance of A from B = 10.8 km

The distance of B from C = 15.5 km

The total distance Ramesh traveled, d₁ = The distance of A from B + The distance of B from C

Therefore;

d₁ = 10.8 km + 15.5 km = 26.3 km

The total distance Ramesh traveled, d₁ = 26.3 km

The distances of the journey of Rahul is as follows;

The distance between place A and D = 11.7 km

The distance between place D and C = 18.2 km

The total distance Rahul traveled, d₂ = The distance between place A and D + The distance between place D and C

d₂ = 11.7 km + 18.2 km = 29.9 km

The total distance Rahul traveled, d₂ = 29.9 km

Therefore, given that d₂(29.9 km) > d₁(26.3 km), Rahul travelled more distance than Ramesh

The difference between the distance Rahul travelled and the distance Ramesh travelled, d₂ - d₁ = 29.9 km - 26.3 km = 3.6 km

Therefore;

Rahul travelled more distance than Ramesh by 3.6 km

Part B

The total distance from place A to place D through place C, d₃, is given as follows;

d₃ = The distance from A to B + The distance from B to C + The distance from C to D

∴ d₃ = 10.8 km + 15.5 km + 18.2 km = 44.5 km

The total distance from place A to place D, d₃ = 44.5 lm

The total distance from place A to place D in meters, m = 1000 m/km × 44.5 km = 44,500 m

The total distance from place A to place D in cm = 100 cm/m × 44,500 m = 4,450,000 cm
