Step-by-step explanation:
Sure, here is an example of how the information provided could be organized in an Excel spreadsheet to calculate Taxable Income and Adjusted Gross Income: see in the attached e1 and e2 screenshots.
It's worth noting that the above example is a simplified version, and the actual calculations for tax purposes would depend on the specific tax laws and regulations in the relevant jurisdiction and year. Also, the numbers provided here are not the final Taxable Income, it's only the calculation of Taxable Income based on the information provided.
A checkout clerk at a department store is expected to complete 16 transactions every hour. In the past 20 minutes, he completed 6 transactions. Choose True or False for each statement. If the clerk continues at the same rate, he will meet his goal of 16 transactions in 1 hour. Choose... At his current rate, the clerk will complete 12 transactions in 1 hour. Choose... At his current rate, the clerk will complete 9 transactions every half hour. Choose... If the clerk continues at this rate for a 6-hour shift, he will complete 96 transactions. Choose...
Step-by-step explanation:
16 transactions per hour (60 minutes).
in short :
16/1
or 16/60 (for minutes instead of 1 hour)
in 20 minutes 6 transactions.
so,
6/20
hour many transactions then in 1 hour (60 minutes) ?
60 = 20×3
so, to bring the ratio to 1 hour (60 minutes) we need to multiply the denominator by 3. and to keep the ratio value, we need to to do the same thing also to the numerator.
therefore,
6/20 × 3/3 = 18/60
so, the clerk will do 18 transactions per hour.
he will meet his goal of 16 : true
he will even exceed but definitely meet his goal.
12 transactions in 1 hour : false
9 transactions every half hour : true
as he will do 18 transactions in 1 hour, he will do half of these transactions (9) in half an hour.
96 transactions in 6 hours : false
18/1
6 = 1×6
so, with the same trick as above we get
18/1 × 6/6 = 108/6
and we see, he would complete 108 transactions in a 6- hour shift.
96 would be right, if the actual ratio would be 16/1 :
16/1 × 6/6 = 96/6
If BD=7x-10, BC=4x-29, and CD=5x-9, find each value
Answer: We know that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Using the triangle inequality theorem, we can set up the following inequality:
BD + BC > CD
7x - 10 + 4x - 29 > 5x - 9
Simplifying, we get:
11x - 39 > 5x - 9
Subtracting 5x from both sides, we get:
6x - 39 > -9
Adding 39 to both sides, we get:
6x > 30
Dividing by 6 from both sides, we get:
x > 5
So x must be greater than 5.
To find the value of BD, we can substitute the value of x in the equation:
BD = 7x - 10
BD = 7(5) - 10 = 25 - 10 = 15
To find the value of BC, we can substitute the value of x in the equation:
BC = 4x - 29
BC = 4(5) - 29 = 20 - 29 = -9
To find the value of CD, we can substitute the value of x in the equation:
CD = 5x - 9
CD = 5(5) - 9 = 25 - 9 = 16
So, BD = 15, BC = -9, CD = 16

and m∠F=131°.
Round your final answer to the nearest tenth. **
Angle D= Angle E= Angle d=
Answer:
Step-by-step explanation:
Using the Law of Cosines, we can find the remaining angle measures of the triangle.
Angle D = cos-1[(25^2 - 8^2 - (25^2 * cos(131°)))/(-2*8*25)] = 20.5°
Angle E = cos-1[(8^2 - 25^2 - (8^2 * cos(131°)))/(-2*25*8)] = 61.4°
Angle F = 180° - (20.5° + 61.4°) = 98.1°
Round to the nearest tenth:
Angle D = 20.5°
Angle E = 61.4°
Angle F = 98.1°

Option 1: Solving by Factoring
Please explain in detail the strategy, Solving by Factoring, discussed in the lesson Quadratic in Form Polynomials. Include an example with this explanation to clearly explain the process.
Answer:
Step-by-step explanation:
Solving by factoring is a strategy used to solve quadratic in form polynomials, which are equations that can be written in the form of ax^2 + bx + c = 0. The goal of this strategy is to factor the equation into two binomials that are equal to zero. Once the equation is factored, we can use the zero product property to set each binomial equal to zero and solve for the roots or solutions of the equation.
The process of factoring begins by finding the greatest common factor of all the terms in the equation. Once the GCF is identified, it can be factored out of the equation. Next, we look for two binomials that multiply to give the remaining terms in the equation and add to give the remaining constant term.
For example, consider the equation: 3x^2 + 6x - 9 = 0.
To factor this equation, we first find the GCF of all the terms, which is 3. We can factor out 3 from all the terms, giving us: 3(x^2 + 2x - 3) = 0.
Now, we look for two binomials that multiply to give x^2 + 2x - 3 and add to give -2. We can see that (x-3)(x+1) satisfies this condition.
By factoring the equation, we have now factored the polynomial into (x-3)(x+1) = 0. We can use the zero product property to set each binomial equal to zero and solve for the roots: x-3 = 0 and x+1 = 0. The solutions are x=3 and x=-1.
By using the factoring strategy, we were able to solve the quadratic in form polynomial 3x^2 + 6x - 9 = 0 and find the roots x=3 and x=-1. This strategy can be applied to any quadratic in form polynomial and is a useful tool in solving equations.

7.86x4.564 report the following answer into significant figures
Answer:
35.87
Step-by-step explanation:
First, what is 7.86 by 4.564?
It is 35.87304.
But the answer needs to be in significant figures, so how do we do that?
Well, significant figures are the numbers that comes after the decimal place. For example, 0.52, which has 2 significant figures.
So with 7.86, there are 2 significant figures and with 4.565, there are 3.
We want to use the one with the least amount of significant figures, so we would round our answer to the hundredth:
35.87
Hope this helps!
The required answer is 35.8730
The number of significant figures in a measurement represents the level of precision in that measurement. In general, the last digit in a number is considered uncertain and is rounded based on the number of significant figures.
When performing arithmetic calculations, the result should be rounded to the same number of significant figures as the least precise measurement used in the calculation.
In this case, the least precise measurement is 4.564, with four significant figures. Therefore, the final result of the calculation 7.86 x 4.564 should be reported with four significant figures.
The answer is 35.87304 and should be reported as 35.8730

What is the value of y that makes T Parallel to U
Answer: y = 18
Sentence: The value of y that makes T Parallel to U is 18.
Step-by-step explanation:
We are given 3 expressions:
(7x)(6y + 9)(3x + 36)We know that since the angle (7x) is on the same line as the angle (3x + 36), we can therefore determine that they correspond to each other. I referred an image to help demonstrate this concept. So since they correspond to each other, that means they have the same value (meaning they are equal to each other).
We can set both expressions equal to each other.
7x = 3x + 36
And solve:
7x = 3x + 36
-3x -3x
4x = 36
/4 /4
x = 9
now we know the value of x, we can plug it into one of the equations. We can plug it in to 3x + 36 to help with the process in solving y.
3(9) + 36 = 63 degrees
Since 6y + 9 and 3x + 36 (63 degrees) are supplementary angles, we can subtract 180 from 63.
180 - 63 = 117
now we know that 117 degrees = 6y + 9 BUT!, we need to solve for y, because that's what the question is asking for.
So lets solve for y:
117 = 6y + 9
-9 -9
108 = 6y
/6 /6
y = 18

converting within measurement sytems
Converting within measurement systems means that we are changing the unit of measurement from one to another.
What is Converting within measurement systems?It is referred to as converting units within measuring systems if we do it using the metric or conventional systems. The conventional system and the metric system are the two most widely used measurement systems. In other words, we are not converting units from customary to metric or vice versa.
Simple unit conversions can be performed mentally or with one-step multiplication or division. There are, however, more difficult conversions that call for many conversions between a wide range of units.
The Unit Factor Method, another name for the Dimensional Analysis process, is a mathematical technique that takes advantage of the fact that any number or statement may be multiplied by "one" without changing its value. By multiplying the previous measurement by one (or more) different representations of the number 1, you can convert units. Although the measurement's value is unaffected by the factor of 1, the measurement's units are.
A ratio of one is referred to as a conversion ratio or unit factor. The names of the units that will be used in the conversion are listed in this ratio. It can be used to convert values both within the English and Metric Systems and between the two. The idea of equivalent values serves as the foundation for the conversion ratio.

A bank has launched a three-year structured deposit that offers an effective annual interest of 8% for the first 18 months, quarterly interest of 1.5% for the next 6 months and semi-annual interest of 2% for the last 12 months. If I wish to receive $100, 000 on the maturity date (that is, on the last day of the third year), how much, to the nearest dollar, should I invest? (Assume that interest rates and principal are guaranteed)
Answer:
To determine how much you should invest to receive $100,000 on the maturity date, you will need to calculate the present value of the cash flows at the beginning of the investment. The present value is the amount of money you would need to invest today to receive a certain amount at a future date, taking into account the time value of money and the interest rate.
You can calculate the present value by using the formula:
PV = CF / (1 + r)^t
Where:
PV = present value
CF = cash flow (the amount you will receive at the maturity date)
r = interest rate
t = time (in years)
The first 18 months, the interest rate is 8% per year, which is equivalent to 8/12 = 0.67% per month.
The next 6 months, the interest rate is 1.5% per quarter, which is equivalent to 1.5/4 = 0.375% per month.
The last 12 months, the interest rate is 2% per semi-annual, which is equivalent to 2/2 = 1% per month.
For the first 18 months, the present value of the cash flow is:
PV = 100,000 / (1 + 0.0067)^(18/12) = 95,167
For the next 6 months, the present value of the cash flow is:
PV = 95,167 / (1 + 0.00375)^(6/12) = 94,853
