Answer:
He owes $33556.08 worth of self employment tax.
Explanation:
consider firstly calculating the profit that he has made after this period which can be calculated as profit= income minus expenses and in this case we are given income earned from self employment of $143380 and the expenses incurred in generating this income is $3563 so we find he difference in these two amounts which is $143380$3563 = $139817 therefore this profit is the taxable income that he needs to deduct tax from.
in order to calculate tax from this amount we go to the tax table so therefore a person earning between $84201 to $160725 is charged 24% tax as per tax table. so now we will say $139817 x 24% = $33556.08 is the tax he owes the IRS.

Hence proved that triangle AB = 3(3)  1 = 9  1 = 8.
What is triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the display style for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a twodimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higherdimensional Euclidean spaces. Except when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.
Given that,
AB + AC = AC
3y  1 + 7y = 29
10y = 29 + 1 = 30
y = 30/10 = 3
Therefore, AB = 3(3)  1 = 9  1 = 8.

(2x + 5.9) +8.3 = 4+3(x+ 2.8)
Answers
Answer:
x =10
Stepbystep explanation:
Equation
(2x + 5.9) +8.3 = 4+3(x+ 2.8) Carefully remove both sets of brackets
Solution
2x  5.9 + 8.3 = 4 + 3x + 8.4 Combine like terms on both sides
2x + 2.4 = 3x + 12.4 Add 3x to both sides
2x+3x + 2.4 = 3x+3x + 12.4 Combine
x + 2.4 = 12.4 Subtract 2.4 from both sides
x + 2.4  2.4 = 12.4  2.4 Combine
x = 10
Rachel is making premade 3inch by 5inch tile rectangles for her driveway. If it takes her 6 minutes to position each rectangle, how many hours will it take her to create a 2foot by 4foot pattern drive? Write your answer as a decimal.
Answers
This is a Metric conversion problem. Note that it will take 38.4 minutes to create a 2foot by 4foot pattern drive. See the explanation below.
What is the calculation justifying the above answer?
There are several ways to do this. Let's use the area of the times and that of the pattern drive.
Note that the area of the 3inch by 5inch tile =
Area of a rectangle
L x B =
3 x 5
= 15inches
Applying the same rule to the pattern drive, we have
2 x 4
= 8 foot
Note that 1 foot = 12 inches
For convenience, thus, we convert the area of the pattern drives into inches. This gives us:
8 x 12
= 96 inches
To get how many minutes it will take to create a 2 by 4foot pattern drive, we have
Recall that it takes 6 minutes to lay a 3x5 which is 12 inches in area.
Hence,
96/15
= 6.4
6.4 x 6
= 38.4 minutes.
Hence, it will take Rachel 38.4 minutes to lay a 2 by 4foot pattern drive given the parameters above.

what property is 3x+2x+17=x+22
Answers
x = 7
The property used is associative property.
If you need to solve it, here’s how:
First, combine the like terms of the constants (numbers that aren’t multiplied by a variable) by subtracting 1 by 7. This gets 6
3x + 2x 6 = x + 22
Now combine the like terms of the coefficients (numbers that are being multiplied by a variable) by adding 3x to 2x. This gets 5x.
5x  6 = x + 22
You now want to remove the 6 because it is on the side of a coefficient. Remove it by adding 6 to 6 to get 0. Make sure to do this on both sides.
5x  6 + 6 = x + 22 + 6
5x = x + 28
Now you can see that there is a variable (x) on the side of a constant (28), remove the x by subtracting x. Do this to both sides. All x’s automatically equal one because it is unknown.
5x  x = x  x + 28
4x = 28
Divide by 4 on both sides.
4x/4 = 28/4

6x  20 = 4y
When x = 0:

y = 20/4 = 5
So, one point on the graph

When y = 2:
Plugging y = 2 into the equation:
6x  20 = 4(2)
6x = 8 + 20 = 12

suppose that you have 15 quarters, 10 dimes, 10 nickels, and 10 pennies in your pocket. you reach in and choose a coin at random so that you can give it to your child. what is the expectation? (round your answer to two decimal places.)
Answers
If you have 15 quarters, 10 dimes, 10 nickels and 10 pennies, then the probabilities of getting quarter, dimes, nickels and pennies are 0.33, 0.22, 0.22 and 0.22 respectively.
Total number of quarters = 15 quarters
Total number of dimes = 10 dimes
Total number of nickels = 10 nickels
Total number of pennies = 10 pennies
Total number of coins = 15+10+10+10 = 45
The probability of getting a quarters = 15/45
= 0.33
The probability of getting a dimes = 10/45
= 0.22
The probability of getting a nickel = 10/45
= 0.22
The probability of getting penny = 10/45
= 0.22
Hence, if you have 15 quarters, 10 dimes, 10 nickels and 10 pennies, then the probabilities of getting quarter, dimes, nickels and pennies are 0.33, 0.22, 0.22 and 0.22 respectively.

#2 The number of bacteria in a refrigerated food is given by N(T)=20T220T+120 for 2T14 Tand where T is the temperature of the food in Celsius.
(a)Explain the meaning of 2T14 in this context
(b)Determine the temperature the number of bacteria will be minimal?
(c)Find number of bacteria in a above
(d) Sketch a graph
Answers
From the given quadratic function, it is found that:
a) The interval 2 ≤ T ≤ 14 gives the range of the temperature of the food in Celsius.
b) The number of bacteria will be minimal for a temperature of 0.5 ºC.
c) The minimum number of bacteria is of 115.
d) The graph that models the situation is sketched at the end of the answer.
What does the quadratic function models in this problem?
The quadratic function is given as follows:
N(T) = 20T²  20T + 120, 2 ≤ T ≤ 14.
In which:
T is the temperature in Celsius of the food.N(T) is the number of bacteria in the food.
The function has a domain of 2 ≤ T ≤ 14, meaning that these are the possible temperatures of the food.
For a concave up quadratic function, the minimum value happens when the input is of:
Tm = b/2a.
For this problem, the coefficients of the quadratic function are as follows:
b = 20, a = 20.
Hence the temperature in which the number of bacteria will be minimal is of:
Tm = 20/40 = 0.5 ºC.
The number of bacteria with this temperature is given by the numeric value of the function when T = 0.5, that is, each instance of T in the function is replaced by 0.5, hence:
N(0.5) = 20(0.5)²  20(0.5) + 120 = 115 bacteria.

How to find the numeric value of a function or of an expression?
To find the numeric value of a function, we replace each instance of the variable in the function by the desired value. This also works for multivariable functions or expressions, as each instance of each variable will be replaced by their attributed values.
For this problem, the expression is given by:
16 + 4(3q + p)

What is ratio ?
By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other. There are two different categories for ratios. The first is a part to part ratio, whereas the second is a part to whole ratio. The relationship between two separate entities or organizations is shown by the parttopart ratio. For instance, a class has a 12:15 boytogirl ratio, whereas the parttowhole ratio describes how one group compares to another. For instance, five people enjoy reading books out of every ten persons. Since the ratio of the component to the total is 5:10, 5 out of every 10 persons enjoy reading.
