Daniel has a yearly income of $41,300 and claims 4 exemptions. The amount allowed for each exemption is $900. His local tax is4 3/4%. How much local income tax should be withheld from his weekly earnings? (Round your answer to the nearest cent.)
Answer:
$34.37.
Step-by-step explanation:
To calculate Daniel's local income tax withholding, we first need to determine his taxable income. To do this, we subtract the value of his exemptions from his yearly income: $41,300 - (4 x $900) = $37,500.
Next, we need to convert the local tax rate of 4 3/4% to a decimal by dividing it by 100: 4 3/4% = 0.0475.
Finally, we can calculate Daniel's local income tax withholding by multiplying his taxable income by the local tax rate: $37,500 x 0.0475 = $1,793.75.
To find the amount of local income tax that should be withheld from Daniel's weekly earnings, we simply divide his total local income tax by the number of weeks in a year: $1,793.75 / 52 = $34.37. Therefore, Daniel's local income tax withholding from his weekly earnings should be $34.37.
How many real roots does the quadratic equation x2 5x 7 0 have?
The equation x^2 - 5x + 7 = 0 has no real roots.
We know that the general form of a quadratic equation is:
ax^2 + bx + c =0
The equation we have is:
x^2 - 5x + 7 = 0
On comparing the given equation with the general form of a quadratic equation, we get that:
a = 1, b= -5, and c = 7
If D = b^2 - 4ac < 0, then the roots of the quadratic equation are imaginary or there are no real roots.
Therefore, b^2 - 4ac = (-5)^2 - 4x1x7 = -3<0.
Hence, we conclude that the nature of the roots of the give equationis imaginary, thus it has no real roots.

How would you define this triangle by its angles and its sides?
Answer:
Equilateral Triangle
A triangle with all the sides equal is called an equilateral triangle.
Isosceles Triangle
A triangle with at least two sides equal is called an isosceles triangle.
Scalene Triangle
If all the sides of a triangle are unequal, i.e., if the sides are of different lengths, the triangle is called a scalene triangle.
Acute Triangle
An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.
Obtuse Triangle
Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.
Right Triangle
A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse. You may come across triangle types with combined names like right isosceles triangle and such, but this only implies that the triangle has two equal sides with one of the interior angles being 90 degrees.

C 35m + 50 = 419
D 50m - 35 = 410
Answer:
C

I'm guessing you misspelled 410 as 419, but the equation is y=mx+b
Kim wants the money amount she puts in to pay off her $410 phone, or in other words, add up to $410.
The constant, or b, is 50. The m is 35, and the x is the months.
35m + 50 = 410
Answer: C. 35m + 50 = 410
Step-by-step explanation:
We know the cost is 410, so it will be = 410
We know that she pays 35 each month, which mean it is 35m

How do you describe a line on a graph?
A line on a graph is a series of points connected by a straight line. It is used to show continuous change or a relationship between two variables.
A line on a graph is a visual representation of a continuous change or a relationship between two variables. It is made up of a series of points connected by a straight line, making it easy to compare changes in data over a period of time. The points on the line represent the values for the two variables being graphed, with the horizontal axis (x-axis) representing one variable and the vertical axis (y-axis) representing the other. The points on the line can be joined with either a straight line or a curved line, depending on the type of data being graphed. For example, a straight line will be used to show a linear relationship between two variables, while a curved line might be used to show a non-linear relationship. By examining the line, it is possible to determine the rate of change or the correlation between the two variables being graphed.

Geometry.
1. Reasoning What is the advantage of using coordinates O(0,0),
E(0, 2b), and F(2a, 0) rather than O(0, 0), E(0, b), and F(a, 0)?
Using coordinates O(0,0), E(0, 2b), and F(2a, 0) rather than O(0, 0), E(0, b), and F(a, 0) has the advantage of allowing the graph to be stretched or shrunk uniformly in both the x- and y-directions by a factor of 2. This can be useful if the scale of the graph needs to be adjusted, or if the graph needs to be compared to another graph with a different scale. It can also make the graph easier to read if the values of the variables being plotted are very large or very small.
By using coordinates that are multiples of the original coordinates, the shape of the graph is preserved, but the scale is changed. This can be useful if the purpose of the graph is to compare the relationships between different variables, rather than to provide an accurate representation of the actual values of the variables.
