If someone makes $200,000 per year, receives a paycheck monthly and pays 25.6% in income tax, how much is deducted from each paycheck for income tax?
Answers
$4266.67 is deducted every month for income tax.
Step-by-step explanation:
Given,
Amount earned per year = $200,000
Income tax = 25.6%
Amount of income tax = 25.6% of amount earned
Amount of income tax = [tex]\frac{25.6}{100}*200000 = \frac{5120000}{100}[/tex]
Amount of income tax = $51200
As this amount is yearly, therefore, we will divide it by 12 to find monthly amount.
Income tax deducted per month = [tex]\frac{51200}{12}=\$4266.67[/tex]
$4266.67 is deducted every month for income tax.

Answer: 1/2
Step-by-step explanation: When dividing integers, if the signs are the same, the quotient is positive. So a negative divided by a negative always equals a positive. In this problem -3 ÷ -6 is 0.5.
However, there is no 0.5 on the list so we need to write the decimal as a fraction.
To write the decimal 0.5 as a fraction, we use the place value chart. 0.5 means 0 units and 5 tenths which can be written as the fraction 5/10.
Notice however that 5/10 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 5 and 10 which is 5 to get the equivalent fraction 1/2.

Step-by-step explanation:
ED2020
Final answer:
Will would have saved approximately $9,420.12 in 10 years by contributing 9% of his $41,000 salary annually, with a 3% employer match and a 7.13% interest rate.
Explanation:
To calculate how much Will would have saved in 10 years, we need to consider both his salary contribution and the employer's matching contribution. Will saves 9% of his $41,000 salary every year, which comes out to $3,690. The employer matches his contribution up to 3%, so the employer would contribute an additional $1,230 (3% of $41,000) every year.
To calculate the total savings after 10 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt). In this case, the principal P is the total annual contributions, the interest rate r is 7.13%, and n is the number of times interest is compounded per year, which we will assume to be once per year.
Using the formula, we can calculate:
A = ($3,690 + $1,230)(1 + 0.0713/1)^(1*10)
A = $5,920 * 1.0713^10
A = $9,420.123296
Rounding to the nearest cent, Will would have saved approximately $9,420.12 in 10 years.
Roy has decided to visit the new ice cream shop around the corner. When he goes in, he sees 16 big buckets full of ice cream behind the counter, each containing a different flavor. There are 6 flavors that contain chocolate.
If he closes his eyes and picks out a bucket at random, what is the probability that the flavor he picks will contain chocolate?
A.
B.
C.
D.
Answers
Answer:
6/17
Step-by-step explanation:
To find the probability that Roy picks a chocolate flavor at random, we need to use the basic probability formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \]
In this scenario:
- The favorable outcomes are the number of chocolate flavors.
- The total number of possible outcomes is the total number of flavors.
According to the given situation, there are a total of 16 flavors of ice cream, and out of these, 6 flavors contain chocolate.
Using the probability formula:
\[ \text{Probability of picking a chocolate flavor} = \frac{6}{16} \]
To simplify the fraction, we can divide both the numerator and the denominator by the greatest common divisor, which in this case is 2:
\[ \frac{6 \div 2}{16 \div 2} = \frac{3}{8} \]
Now, to express this as a decimal, we divide 3 by 8:
\[ 3 \div 8 = 0.375 \]
Therefore, the probability that Roy picks a chocolate flavor at random is 0.375. If you're looking at multiple-choice answers, you would choose the option that best fits this answer.
if 4 people are responsible for 25% of the work and one is doing .025 how much work do the other 3 take on?
Answers
Answer:
22.5%
Step-by-step explanation:
1 person is doing 0.025 of the work. What is that in percent??
We convert decimal to percentage by multiplying by 100 and sticking the "%" sign.
So,
0.025 * 100 = 2.5%
Hence, 1 person is doing 2.5% of the total 25% of the work alloted to 4 persons.
The other 3 would do rest of the work, that would be:
25% - 2.5% = 22.5% of the work (rest 3 person would be)

How many integers have a square root that is greater than 10 and less than 11?
Answers
Answer:
20
Step-by-step explanation:
We know that 10² = 100, so all integers above 100 have a square root greater than 10. Similarly, 11² = 121, so all integers below 121 have a square root less than 11. So, we want the integers from 101 through 120, inclusive. There are integers from through (just as there are 20 integers from 1 through 20).

Answers
I NEED A FREE BRAINLIEST ASAP
Answer:
Joey must get a score of 94 to have a average test score of 90.
Step-by-step explanation:
Joey wants a average score of 90.
He already scored 91 and 85 on the previous two tests, and wants to know the score to get a 90 as an average.
Set the equation:
Average = (score of known tests + x)/(amount of tests in all).
Note that: x = score of the next test.
First, Plug in the corresponding numbers to the corresponding terms/variables:
90 = (91 + 85 + x)/(3)
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, multiply 3 to both sides:
90(3) = (91 + 85 + x)/(3) * 3
270 = 91 + 85 + x
Isolate the variable x. Combine like terms:
270 = (91 + 85) + x
270 = 176 + x
Subtract 176 from both sides:
270 (-176) = 176 (-176) + x
x = 270 - 176
x = 94
Joey must get a score of 94 to have a average test score of 90.

dori left her house at 12:00 pm and walked at 50 steps per minute and malory left her house at 12:20 and walked 90 steps per minute what time did malory catch up to dori?
Answers
Final answer:
Malory catches up to Dori 25 minutes after starting her walk. Since Malory started at 12:20 pm, she catches up to Dori at 12:45 pm by walking at a faster pace.
Explanation:
To determine what time Malory caught up to Dori, we can set up an equation based on the distance each has traveled. Since distance equals speed multiplied by time, and steps per minute can be considered as speed, we need to find a point at which they have both covered the same distance.
Dori started walking at 12:00 pm and Malory started at 12:20 pm, so Malory starts walking 20 minutes later. We'll use t to represent the time in minutes that Malory has been walking when she catches up to Dori.
Thus, Dori has been walking for t + 20 minutes by the time Malory catches up.
We set up the following equation to find t:
Dori's distance = Malory's distance
50 steps/minute × (t + 20) = 90 steps/minute × t
Solving for t gives us:
50t + 1000 = 90t
1000 = 40t
t = 25 minutes
Therefore, Malory catches up to Dori 25 minutes after Malory started walking. Since Malory started walking at 12:20 pm, we add 25 minutes to this time to find out the catch up time is 12:45 pm.

The average test score of RSM students in September increased by 10%. In October it increased by another 15%. By what percent did the average score on the test increase during the two months? PLEASE HELP I NEED THE ANSWER QUICK
Answers
Answer:
26.5%
Step-by-step explanation:
Increasing Percentages
When sequential percentages increasing are computed, each increase applies to the previous result, instead of the first quantity. That is why sometimes the final results may be confusing. For example, increasing 10% and then 15% will not be the same as increasing a total of 25%.
The average test scores of RSM students first increased by 10%. It means that some quantity C increased by
[tex]10C/100=0.1C[/tex]
Now the average test scores are
[tex]C+0.1C=1.1C[/tex]
A new increasing occurred by 15%, and the previous quantity must be multiplied by 1.15, so the final average test scores are
[tex]1.15(1.1C)=1.265C[/tex]
It means that the total increasing was [tex]100(1.265-1)=26.5\%[/tex]

Which graph represents the solution to the given system ? Y=- 6X - 2Y +2=- 6X
Answers
Answer: The graph is attached.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
Given the first equation:
[tex]y=- 6x - 2[/tex]
You can identify that:
[tex]m=-6\\b=-2[/tex]
By definition, the line intersects the x-axis when [tex]y=0[/tex]. Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:
[tex]0=- 6x - 2\\\\2=-6x\\\\x=-\frac{1}{3}\\\\x=-0.333[/tex]
Now you can graph it.
Solve for "y" from the second equation:
[tex]y +2=- 6x\\\\y=-6x-2[/tex]
You can identify that:
[tex]m=-6\\b=-2[/tex]
Notice that the slopes and the y-intercepts of the first line and the second line are equal; this means that they are exactly the same line and the System of equations has Infinitely many solutions.

kamari loses 3 points for each wrong answer on a test. How does his score change if he has 7 wrong answers?
Answers
Answer: 21
Step-by-step explanation:
If kamari loses 3 points for 1 question. How many would he lose for 7 questions. So basically, you times 3 points by 7 questions to get 21
Kamari's score decreases by 21 points due to 7 wrong answers.
To determine the change in Kamari's score, we need to calculate the total number of points he loses for the 7 wrong answers. Since he loses 3 points for each wrong answer, we multiply the number of wrong answers by the points lost per wrong
Number of wrong answers = 7
Points lost per wrong answer = 3
Total points lost = Number of wrong answers — Points lost per wrong answer
Total points lost = 7 — 3
Total points lost = 21
Therefore, Kamari's score decreases by 21 points.

Answers
The expression for how both booths will cost for the same number of days (d) is 150 + 12d
Step-by-step explanation:
A company set up a food booth and a game booth at a county fair
The fee for the food booth is $100 + 5 dollars per dayThe game booth is $50 + 7 dollars per dayWe need to write an expression for how both booths will cost for the same number of days
Assume that the number of days is d for both booths
∵ The fee for the food booth is $100 + 5 dollars per day
∵ It used for d days
∴ The cost of the food booth = 100 + 5(d) ⇒ (1)
∵ The fee for the game booth is $50 + 7 dollars per day
∵ It used for d days
∴ The cost of the game booth = 50 + 7(d) ⇒ (2)
To find the cost for both booths in d days add (1) and (2)
∵ The cost for both booths = 100 + 5d + 50 + 7d
- Add the like terms
∴ The cost for both booths = (100 + 50) + (5d + 7d)
∴ The cost for both booths = 150 + 12d
The expression for how both booths will cost for the same number of days (d) is 150 + 12d

If u (x) = negative 2 x squared and v (x) = StartFraction 1 Over x EndFraction, what is the range of (u circle v) (x)?
(one-third, 0)
(3, infinity)
(negative infinity, 3)
(negative infinity, positive infinity)
Answers
The range of (u circle v) (x) is (negative infinity, 0).
Explanation:To find the range of (u circle v) (x), we need to substitute v(x) into u(x), which means replacing x in u(x) with v(x).
u(x) = -2x²
So, (u circle v) (x) = -2(v(x))² = -2(1/x)² = -2/x²
The range of (u circle v) (x) is (negative infinity, 0) because as x approaches 0 from the right, (-2/x²) approaches negative infinity, and as x approaches 0 from the left, (-2/x²) approaches positive infinity.
