Agnes pays state income tax equal to 3.75% of her federal taxable income. She pays federal income tax equal to 28.4% of her federal taxable income. This year she paid $15,449.60 in federal income tax. How much did Agnes pay in state income tax?
Answers
The amount that Agnes paid in state income tax is; SI = $2,040
How to calculate state income tax?To find the state income tax in this situation, we would use this equation:
t = px
Where;
t = Total paid
p = percentage
x = federal income tax
In this case, we would need to find what x is.
We are given;
Total paid = $15,449.60
Percentage of federal tax = 28.4% = 0.284
The equation is;
15,449.60 = 0.284x
dividing both sides by 0.284 gives;
x = $54,400.
Now, we can calculate Agnes' state income tax from the formula:
SI = x × p
SI = 54400 × 0.0375
SI = $2,040

Which of the following quantities are directly proportional?
the amount of homework received by an RSM teacher and the time that the teacher
spent grading it PLS HELP I WILL GIVE BRAINLEIST
Answers
The amount of homework received by an RSM teacher and the time that the teacher spent grading it is the case of directly proportional.
What are direct and indirect variations ?
One quantity directly changes in response to a change in another quantity, which is referred to as direct variation. This suggests that if one quantity increases, the other will follow suit and rise in proportion. In a similar manner, if one quantity declines, the other amount also declines.
When one parameter declines while the other rises or vice versa, this is known as inverse variation. This means that the magnitude or absolute value of one item decreases as the other quantity rises, resulting in a constant value for their product. This item is also referred to as the proportionality constant.
Direct proportion occurs when one value increases and the other also increases
As the amount of homework received by an RSM teacher increases, the time that the teacher spent grading it also increases.
So, this is a case of directly proportional.

What can be values and units.Let's say you go to the store to buy six apples. You are informed by the shopkeeper that he is offering 10 apples for Rs 100. In this instance, the value and the units are the price of the apples.Recognizing the units and values is crucial when using the unitary technique to a problem.Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things.We are aware of the quantity of apples and the amount of money in the aforesaid problem.According to our question-
inverse proportionality means L = k/l
So the equation is:
L = k(wd2/l)
You are given:
w = 6 in
d = 5 in
l = 12 ft
L = 7666 lbs
7666 = k(6*52/12)
Solve for the constant, k.
7666 = k (6*25/12)
7666 = k (150/12)
7666 = k (12.5)
613.28 lbs/(ft.in3) = k
Use this k-value to solve for L in the last part of the question.

The result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)
The given expression is
(x / m^2 - 2x / m)(3x^2y / m)
Here we have to apply distributive property
The distributive property states that multiplying the sum of two or more variable by a number gives the same result as when each variable is multiplied individually by the number and the products are added together.
The distributive property of subtraction is
A(B-C) = AB - AC
Apply the distributive property
(x / m^2 - 2x / m)(3x^2y / m)
= (x / m^2)(3x^2y / m) - (2x / m)(3x^2y / m)
Multiply the terms
= (3x^3y / m^3) - (6x^3y / m^2)
Hence, the result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)

Step-by-step explanation:
We know that,

Forming the equation,
→ (4x - 25)° = 75°
Now the value of x will be,
→ (4x - 25)° = 75°

when f(x) = -3 what is x?
Answers
The function f(x) = -3; the value of x is not defined as the function is independent of 'x'.
What is defined as the independent function?The independent variables are function inputs, while the dependent variables are function outputs.
The value of the a dependent variable is determined by the input. The independent variable, on the other hand, is unrelated to anything; it is simply whatever you want to put in! The connection between the dependent as well as independent variables can be investigated.We can openly manipulate independent variables by trying to plug in any input value. In most math problems, we consider x to be the independent variable because it is the one we generally change.On a graph, we generally plot the independent variable just on horizontal axis (which we also call the x-axis).For the given question;

-6 - (-5) = -6 + 5 == -1
Now x:
x2 is 0, and x1 is 0
Set up the equation:
x2-x1
Plug in our values:
0-0 = 0
Now, put those two values together and you have the slope!
-1/0 is the slope
We can simplify this further though.
