A man earned wages of $36,300, received $2200 in interest from a savings account, and contributed $2700 to a tax-deferred retirement plan. He was entitled to a personal exemption of $4050 and a standard deduction of S6300. The interest on his home mortgage was $7800, he contributed $2900 to charity, and he paid $1750 in
state taxes. Find his gross income, adjusted gross income, and taxable income Base the taxable income on the greater of a standard deduction or an itemized
deduction
Answer:
Gross income = $38500
Adjusted gross income = $35800
Taxable income = $13000
Step-by-step explanation:
1. Gross income = wages + interest received
Gross income = $36,300 + $2200
Gross income = $38500
2. Adjusted gross income = Gross income - adjustments
Adjusted gross income = $38500 - $2700
Adjusted gross income = $35800
3. Taxable income = adjusted income - (exemption + deductions)
Taxable income = $35800 - ($4050 + $6300 + $7800 + $2900 + $1750)
Taxable income = $35800 - $22800
Taxable income = $13000

Here are a triangle and a rectangle . width The area of the rectangle is 6 times the area of the triangle. Work out the width of the rectangle.
Answer:
10 cm
Step-by-step explanation:
From the diagram,
Applying,
lw = 5/2(bh)..................... Equation 1
Where l = length of the rectangle, w = width of the rectangle, b = base of the triangle, h = height of the triangle.
make w the subject of the equation
w = 5(bh)/2l............... Equation 2
From the diagram,
Given: l = 12 cm, b = 6 cm, h = 8 cm
Substitute into equation 2
w = 5(6×8)/(2×12)
w = 10 cm
Hence the width of the rectangle is 10 cm
Answer: The Width of The Rectangle = 13.5 cm
Step-by-step explanation:
Area of a right triangle = \(\frac{ab}{2}\)
(a= 9, b= 8)
= \(\frac{9\cdot 8}{2}\)
=36
______________________________
Now,
Area of a rectangle = \(36\cdot 6\)
= 216 (since the area of a rectangle is 6 times the area of the triangle)
_______________________________
(w= width, l= length= 16)
A= \(w\cdot l\)
216 = \(w\cdot 16\)
∴ w = \(\frac{216}{16}\)
= 13.5
∴ Width = 13.5
The radius of a circle is 12 miles. What is the length of an arc that subtends an angle of
4
5
radians?
Using the length formula we know that the length of the given arc is 30.144 miles.
What is an arc?In mathematics, an arc is a portion of the boundary of a circle or curve. It is sometimes referred to as an open curve.
The measurement around a circle that determines its edge is called the circumference, often known as the perimeter.
So, the formula to find the length of the arc is:
Length of an Arc = θ × r
Now, insert values and calculate as follows:
Length of an Arc = θ × r
Length of an Arc = 4π/5 × 12
Length of an Arc = 4π/5 × 12
Length of an Arc = 12.56/5 * 12
Length of an Arc = 2.512 * 12
Length of an Arc = 30.144
Therefore, using the length formula we know that the length of the given arc is 30.144 miles.

What is the equation of a line that is parallel to the line y = 5x – 1 and passes
through the point (4, –3)?
Answer:
y = 5x - 23
Step-by-step explanation:
Since that is ll to y = 5x - 1, slope must be same as that of y = 5y - 1.
Compare y = 5y - 1 with y = mx + c, where m is slope.
Slope of the required line = 5.
And a point lying on that line is (4,-3). Therefore,
Equation is:
=> y - (-3) = 5(x - 4)
=> y + 3 = 5x - 20
=> y = 5x - 23

m/s2. How much time did it take the car to reach its final velocity?
A. 3.7 s
B. 4.8 s
C. 4.9 s
Answer:
\(t = 5.2\ s\)
Step-by-step explanation:
Given
\(a= 12.3m/s^2\) --- acceleration
\(v = 64m/s\) --- final velocity
\(u =0m/s\) --- initial velocity (it is 0, because the car starts from rest)
Required
Determine the time taken
This will be solved using Newton's first equation of motion:
\(v = u + at\)
Substitute values for v, u and a
\(64 = 0 + 12.3*t\)
\(64 = 12.3t\)
\(12.3t = 64\)
Make t the subject
\(t = \frac{64}{12.3}\)
\(t = 5.2\ s\)
Hence, the time taken is approximately 5.2 seconds

The values of the unknown angles are ∠1 = 92°, ∠2 = 24°, ∠3 = 64°, ∠4 = 35°, ∠5 = 81°
What are corresponding angles?Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal). For example, in the below-given figure, angle p and angle w are the corresponding angles.
∠1 + 88 = 180°( angles on a straight line)
∠1 = 180 - 88 which is 92°
∠3 = 64°( corresponding angles are equal)
∠2 + ∠1 + ∠3 = 180( sum of angles in a triangle)
∠2 + 92° + 64° = 180
∠2 = 180 - 92 - 64
∠2 = 24°
∠4 + 81 + ∠3 = 180 ( angles on a straight line)
∠4 + 81 + 64 = 180
∠4 = 180 - 64 -81
∠4 = 35°
∠5 = 81°( alternate angles are equal)
In conclusion the values of ∠1, ∠2, ∠3, ∠4, ∠5 are 92°, 24°, 64°, 35° and 81° respectively.

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
In the given figure side AB = 8.6
Coordinates of A(1, 3), B(8, 8), C(12, 5) and D(5, 0)
Now in the given triangle we will find the angle between Ab and AD to find the length of AE which is the length of the given parallelogram.
Slope m(AB) = 8-3/8-1
=5/7
Slope of AD = -3/4
tan theta = 5/7-(-3/4)/(1+5/7(-3/4))
=41/13
=3.154
Theta = tan ⁻¹(41/13)
=72.41 degrees

Write the rule for the linear function. Remember a function rule is written using f (x) x 7 5 -1 y 2 3 6
The rule for the linear function is f(x) = (-1/2)x + 11/2
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
To write the rule for the linear function, we can start by finding the slope of the line passing through the given points (x, y):
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope= (6 - 2) / (-1 - 7)
Slope= 4 / (-8)
Slope= -1/2
Therefore, the slope of the line passing through these points is -1/2.
Now, we can use the point-slope form of a linear equation to find the equation that represents this relationship:
y - y₁= m(x - x₁)
Where m is the slope and (x1, y1) is any point on the line. Let's use the point (7, 2):
y - 2 = (-1/2)(x - 7)
y - 2 = (-1/2)x + 7/2
y = (-1/2)x + 11/2
Therefore, the rule for the linear function is f(x) = (-1/2)x + 11/2

Twelve cards are numbered from 1 to 12 and placed in a box. One card is selected at random and not replaced. Another is randomly selected. What is the probability of selecting two even numbers?
In this case, we are to determine the probability of selecting two even numbers. This can be solved as follows:There are six even numbers: {2, 4, 6, 8, 10, 12}.We can use the concept of conditional probability since the first event affects the probability of the second event. This can be expressed as follows:
In this case, P(A) represents the probability of selecting an even number, and P(B|A) represents the probability of selecting an even number given that the first card selected was even. P(A) = 6/12 = 1/2 (there are six even numbers and twelve cards in total)P(B|A) = 5/11 (there are five even numbers left in the box after the first even number is selected, and eleven cards are left in total).
The probability of selecting two even numbers can be found by multiplying these probabilities: P(A) x P(B|A) = (1/2) x (5/11) = 5/22Therefore, the probability of selecting two even numbers is 5/22.Answer: 5/22
