Jason earns $232.50 per week as the manager at Big Bucks Department Store. He is single and claimed 1 allowance last year. How much more will be deducted from his weekly check if he claims no
allowances?
The difference in the amount of tax withheld based on his previous W-4 form and the new W-4 form is estimated to be $7 per week for federal income tax withholding, meaning $7 more will be deducted from his weekly check if he claims no allowances.
How to Calculate Claimed Allowances?The amount of tax withheld from Jason's paycheck depends on his taxable income, which is his gross income minus any deductions and exemptions. The number of allowances claimed on his W-4 form affects the amount of his paycheck that is subject to tax withholding.
If Jason claimed 1 allowance last year, his employer withheld tax as if he had $4,300 less in taxable income than if he had claimed no allowances. For 2023, the value of each allowance is $4,350.
Therefore, if Jason claims no allowances on his W-4 form, his taxable income will be $4,350 more than if he claimed 1 allowance.
Jason's gross income is $232.50 per week, which translates to $12,090 per year. If he claimed 1 allowance last year, his taxable income was $12,090 - $4,300 = $7,790. If he claims no allowances this year, his taxable income will be $7,790 + $4,350 = $12,140.
To determine how much more tax will be withheld from his weekly paycheck, we need to calculate the difference in the amount of tax withheld based on his previous W-4 form and the amount of tax withheld based on the new W-4 form.
Assuming that Jason is paid weekly, we can use the IRS tax withholding tables to estimate the federal income tax withheld for each situation.
Based on the 2023 IRS tax withholding tables, if Jason is single and claims 1 allowance, his employer would withhold $32 per week from his paycheck for federal income tax.
If he claims no allowances, his employer would withhold $39 per week from his paycheck for federal income tax.
Therefore, if Jason claims no allowances, $39 - $32 = $7 more will be deducted from his weekly check for federal income tax withholding.

Question 11 Solve the inequality. Write the solution set in interval notation. (5)/(y-4)<9
In interval notation, the the solution set in interval notation. (5)/(y-4)<9 is (41/9, ∞).
What is inequality?Inequality is a mathematical statement that two values or expressions are not equal. It is represented by symbols, like >, <, or ≠, and is used to compare quantities or values.
To solve the inequality (5)/(y-4)<9, we need to isolate the variable on one side of the inequality. We can do this by multiplying both sides of the inequality by (y-4) and then simplifying.
(5)/(y-4)<9
5 < 9(y-4)
5 < 9y - 36
41 < 9y
y > 41/9
This means that any value of y greater than 41/9 will satisfy the inequality.

(a) For a line, the ratio of the change in y to the change in x is called the slope of the line.
(b) The point-slope form of the equation of a line with slope m passing through (x1, y1) is y - y1 = m(x - x1).
The slope of a line is a measure of its steepness and is calculated by finding the ratio of the change in y (the rise) to the change in x (the run) between two points on the line.
The point-slope form of the equation of a line is a way to write the equation of a line when you know its slope and one point on the line. It is written as y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is the point on the line.

Three vases have different sizes. the capacity of the big vase is half times bigger than the capacity of the middle sized vase. the capacity of the middle sized vase is four times bigger than the capacity of the small vase
mark the capacity of the middle vase as x
1. what is the capacity of the big vase (in x?)
2.what is the capacity of the small vase (in x?)
3.all of the 3 vases together have a capacity of 5,5 liters. What is the capacity of the middle vase in liters
middle = x
big = 1/2x + x
small = x/4 I need some help T^T
Answer:
The capacity of the big vase is half times bigger than the capacity of the middle sized vase, which means it is 1 + 1/2 times the capacity of the middle vase.
So, the capacity of the big vase in terms of x is:
1/2x + x = 3/2x
Therefore, the capacity of the big vase in x is 3/2x.
The capacity of the middle sized vase is four times bigger than the capacity of the small vase, which means it is 4 times the capacity of the small vase.
So, the capacity of the small vase in terms of x is:
x/4
Therefore, the capacity of the small vase in x is x/4.
The total capacity of the three vases is 5.5 liters. We can set up an equation based on this information:
x + 3/2x + x/4 = 5.5
Multiplying both sides by 4 to eliminate the fraction:
4x + 6x + x = 22
11x = 22
x = 2
Therefore, the capacity of the middle sized vase is 2 in terms of x. To find the capacity in liters, we can substitute x = 2 into any of the expressions we found earlier:
Capacity of the big vase: 3/2x = 3/2 * 2 = 3 liters
Capacity of the small vase: x/4 = 2/4 = 0.5 liters
So, the capacities of the three vases are 3 liters, 2 liters, and 0.5 liters, and their total capacity is 5.5 liters.
Is(8, 2)a solution to the inequality y ≥ 3x + 4?
No, (8, 2) is not a solution to the inequality y ≥ 3x + 4 because when we substitute x = 8 and y = 2 into the inequality, we get a false statement. In other words, the point (8, 2) does not satisfy the inequality y ≥ 3x + 4, which means it is not a valid solution to the inequality.
To determine whether (8, 2) is a solution to the inequality y ≥ 3x + 4, we need to substitute the values of x and y into the inequality and check if the inequality holds true.
y ≥ 3x + 4
Substituting x = 8 and y = 2:
2 ≥ 3(8) + 4
2 ≥ 24 + 4
2 ≥ 28
The inequality is not true since 2 is not greater than or equal to 28.

If 6 apples cost the same as 3 bananas, and 4 bananas
cost the same as 5 melons, how many melons can Jane buy for the
price of 32 apples?
Jane can buy 20 melons for the price of 32 apples.
To find out how many melons Jane can buy for the price of 32 apples, we need to use the given ratios to find the equivalent value of melons in terms of apples.
First, we know that 6 apples are equivalent to 3 bananas. So, we can simplify this ratio to 2 apples per 1 banana.
Next, we know that 4 bananas are equivalent to 5 melons. So, we can simplify this ratio to 4/5 of a banana per 1 melon.
Now, we can use these ratios to find the equivalent value of melons in terms of apples. If 2 apples are equivalent to 1 banana, and 4/5 of a banana is equivalent to 1 melon, then we can multiply these ratios together to find the equivalent value of melons in terms of apples:
2 apples/1 banana × 4/5 banana/1 melon = 8/5 apples/1 melon
This means that 1 melon is equivalent to 8/5 apples, or 1.6 apples.
Finally, we can use this ratio to find out how many melons Jane can buy for the price of 32 apples:
32 apples × 1 melon/1.6 apples = 20 melons
Therefore, Jane can buy 20 melons for the price of 32 apples.

Write a polynomial in factored form whose solutions are x =
-3, 5/2, and

The polynomial in factored form whose solutions are x = -3, 5/2, and -5i is 2(x + 3)(2x - 5)(x² + 25).
What is the polynomial in factored form whose solutions are x = -3, 5/2, and - 5i?Given the solutions;
x = -3x = 5/2x = -5iTo have the solutions at x = -3 and x = 5/2, the polynomial must have factors of (x + 3) and (2x - 5), respectively.
Also, to have a solution at x = -5i, there must be a factor of (x+5i) and its complex conjugate (x-5i):
Hence;
(x + 3)(2x - 5)(x + 5i)(x - 5i)
Multiplying out these factors gives:
(x + 3)(2x - 5)(x + 5i)(x - 5i)
(x + 3)(2x - 5)(x² + 25)
= (2x² + x - 15)(x² + 25)
= 2x⁴ + x³ - 15x² + 50x² + 25x - 375
= 2x⁴ + x³ + 35x² + 25x - 375

sum the 3 angles and equate to 180
4x + 21 + x - 10 + 2x + 8 = 180
7x + 19 = 180 ( subtract 19 from both sides )
7x = 161 ( divide both sides by 7 )
x = 23
Then angles in triangle are
4x + 21 = 4(23) + 21 = 92 + 21 = 113°
x - 10 = 23 - 10 = 13°
7x + 8 = 7(23) + 8 = 161 + 8 = 169°

The enrollment at high school R has been increasing by 15 students per year.Currently High School R has 200 students attending.High school T currently has 400 students,but it’s enrollment is decreasing in size by average of 10 students per year. If the two schools continue their current enrollment trends over the next few years, how many years will it take the schools to have the same enrollment.
So it will take 20 years for High School R and High School T to have the same enrollment.
What is enrollment?Enrollment is the process of registering for classes at a college or university. The process usually involves submitting an application and providing transcripts and other documents to the school.
The enrollment at High School R is increasing by 15 students per year while High School T is decreasing by 10 students per year. To figure out how many years it will take for both schools to have the same enrollment, we need to calculate the difference between the two schools.
High School R currently has 200 students and High School T has 400 students. The difference between the two schools is 200 students (400-200 = 200).
Since High School R is increasing by 15 students per year and High School T is decreasing by 10 students per year, it will take 20 years for the two schools to have the same enrollment.
To calculate this, we divide the difference between the two schools (200 students) by the difference between the two schools' enrollment growth (15 students - 10 students = 5 students). This gives us 200/5 = 40. Since 40 years is too long, we divide 40 by 2 and get 20, which is the answer. So it will take 20 years for High School R and High School T to have the same enrollment.

The base cost for copying the first 400 pages is $5,000. For each additional page above 400, the customer is charged $0.01 per page. Therefore, to calculate the total cost for copying p pages, we need to subtract 400 from p to determine the number of pages that are being charged at the additional rate, and then multiply that by $0.01 to determine the additional cost. This gives us:
Additional cost = $0.01 × (p - 400)
The total cost is then the sum of the base cost and the additional cost:
t = $5,000 + ($0.01 × (p - 400))
This equation will give us the total cost, t, for any number of pages greater than 400 that are copied.
