9. Two distinct lines, l and m, are each perpendicular to the same line n.
Explain why & and m are parallel lines. (Lesson 1-6)
When two distinct lines, l and m, are each perpendicular to the same line n, it means that the two lines have the same angle of rotation in relation to n.
What is angle?An angle is a figure formed by two lines or rays diverging from a common point. It is measured in degrees, with a full circle representing 360 degrees. Angles are used to describe the direction and orientation of objects, as well as to measure the size of an area or the relationship between two lines. Angles are an important part of mathematics, used in problems such as geometry, trigonometry and calculus.
This angle is equal to 90 degrees, meaning that the two lines are parallel to one another.
Parallel lines are lines that never intersect and are always the same distance apart. This is the case for l and m because both lines are perpendicular to the same line n and, thus, have the same angle. Therefore, the two lines are parallel to one another, meaning that they will never cross and will always remain the same distance apart.

what is the probability of rolling a 6 and then a 2 from one die in that order?
and
how many different ways are there to roll 3 dice??
*PLEASE ANSWER ASAP*
Answer:
1/36 and 216
Step-by-step explanation:
The probability of rolling a 6 or a 2 on either piece of dice is 1/6. Therefore, 1/6x1/6= 1/36.
When rolling three dice, we also need to consider the fact that there is a 1/6 chance of rolling any number. 6x6x6= 216.

Therefore , the solution of the given problem of equation comes out to be the system of equations has an answer of x = 5 and y = -2.
How are equations used?Mathematical formulas frequently use the same variable letter to try to enforce harmony among two assertions. Many academic numbers are shown to be equal using mathematical expression, also known as assertions. In this case, instead of splitting 12 into two parts, the normalise adds b + 6 using the example of y + 6. It is possible to determine the link number between each sign portion and the line length.
Here,
One of the solutions for a single variable should be solved in terms of the other.
We can find x from the first solution by solving in terms of y:
=> 2x + 3y = 4
=> 2x = 4 - 3y
=> x = (4 - 3y)/2
Solve for the other variable by substituting the formula for the variable from step 1 into the other equation.
Change x in the second expression to (4 - 3y)/2:
=> 2x = 7y + 24
=> 2((4 - 3y)/2) = 7y + 24
=> 4 - 3y = 7y + 24
=> -10y = 20
=> y = -2
Solve for the other variable by substituting the value of the variable from step 2 into one of the initial formulae.
When the first solution is used:
=> 2x + 3y = 4
=> 2x + 3(-2) = 4
=> 2x - 6 = 4
=> 2x = 10
=> x = 5
As a result, the system of equations has an answer of x = 5 and y = -2.

Kelly's taxable income is $50,000. Approximately what percent of her taxable income is her tax? Round to one tenth of a percent.
Approximately 24.1% of Kelly's taxable income is her tax.
What is percent?
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
To determine what percent of Kelly's taxable income is her tax, we need to calculate her tax liability first.
Assuming that Kelly files as a single taxpayer with no dependents and takes the standard deduction, her taxable income of $50,000 falls into the 22% tax bracket for the year 2021.
Using the IRS tax tables for 2021, Kelly's tax liability would be approximately:
$9950 + (0.22 * ($50,000 - $40,525)) = $9950 + $2095.50 = $12045.50
Therefore, Kelly's tax liability is approximately $12,045.50.
To calculate what percent of her taxable income is her tax, we can divide her tax liability by her taxable income and multiply by 100:
($12,045.50 / $50,000) * 100 = 24.09%)
Therefore, approximately 24.1% of Kelly's taxable income is her tax. Rounded to one tenth of a percent, this is 24.1%.

If f(x)=4x+8 and g(x) = square root x+4, what is (f °g)(12)
For given functions f(x) and g(x), the value of (f °g)(12) is 24.
What exactly is a function?
In mathematics, a function is a rule that assigns to each input value (also called the argument) exactly one output value. The input values are typically drawn from a specific set, called the domain of the function, and the output values are drawn from another set, called the range of the function.
Now,
To find (f °g)(12), we need to first evaluate g(12) and then use the result to evaluate f(g(12)).
g(x) = √(x+4), so g(12) = √(12+4) = √16 = 4.
f(x) = 4x+8, so f(g(12)) = f(4) = 4(4) + 8 = 16 + 8 = 24.
Therefore,
The value of (f ° g)(12) = f(g(12)) = 24.

What distinguishes the weighted mean from the arithmetic mean?Both the arithmetic mean and the weighted mean may be used to determine the average of a group of integers. The sum of all the numbers in the group divided by the entire amount of numbers in the set yields the arithmetic mean. Regardless of significance or relevance, it gives each integer in the set the same amount of weight. On the other hand, the weighted mean gives the integers in the set distinct weights based on their significance or relevance. This indicates that certain numbers in the set provide a greater weighted mean contribution than others.
Given that, Bobbi's goal was to save an average of $7.00 per week.
Thus the amount saved is:
12 x $7 = $84.
He saved $5 for 11 weeks thus,

Let's start by finding the cοst οf οne apple and οne οrange using the infοrmatiοn frοm twο Saturdays agο:
3a + 4ο = 3.47, where "a" is the cοst οf οne apple and "ο" is the cοst οf οne οrange.
We can simplify this equatiοn by dividing bοth sides by 3: a + 4/3 ο = 1.1567
Nοw, let's use the infοrmatiοn frοm last Saturday:
12ο = 6.36
ο = 0.53
We can substitute this value οf "ο" intο οur simplified equatiοn tο find the cοst οf οne apple:

Where T is the subject of the formula, the expression becomes, T = N²SL/M². (Option B)
What is the explanation for the above response?
To make T the subject of the formula M = N√(SL/T), we need to isolate T on one side of the equation by performing mathematical operations in a way that cancels out all other variables.
Here's how we can do that:
Square both sides of the equation to eliminate the square root:
M² = N²SL/T
Multiply both sides of the equation by T to get rid of the denominator on the right-hand side:
M²T = N²SL
Divide both sides of the equation by M² to isolate T on one side:
T = N²SL/M²

If sin theta = 4/9, then what is the value of sin(pi - theta)
Sin(pi - theta) has a value of 4/9. sin(pi - theta) is equal to sin for any value of theta (theta). sin(pi - theta) has a value of 4/9.
We may calculate the value of sin(pi - theta) using the trigonometric identity sin(pi - theta) = sin(pi)cos(theta) - cos(pi)sin(theta):
Pi minus theta equals sin (pi)
cos(pi)sin - cos(theta) (theta)
We may simplify the expression to: since sin(pi) = 0 and cos(pi) = -1
0*cos(theta) - (-1)*sin = sin(pi - theta) (theta)
Pi minus theta equals sin (theta)
The value of sin(theta) can now be substituted to obtain:
Theta = 4/9 sin(pi - theta)
Hence, sin(pi - theta) has a value of 4/9.
The value of theta determines the value of sin(pi - theta). In terms of the trigonometric functions of theta, there is a generic formula to get sin(pi - theta): Pi minus theta equals sin (pi)
cos(pi)sin - cos(theta) (theta)
We may simplify the expression to: since sin(pi) = 0 and cos(pi) = -1
0*cos(theta) - (-1)*sin = sin(pi - theta) (theta)
Pi minus theta equals sin (theta)
Hence, sin(pi - theta) is equal to sin for any value of theta (theta).

In how many ways can 6 people be seated in a row of 9 chairs
There are 60,480 ways to seat 6 people in a row of 9 chairs using the multiplication principle of counting.
There are 9 choices for the first person, 8 choices for the second person (since one chair is already taken), 7 choices for the third person, and so on. Therefore, the total number of ways 6 people can be seated in a row of 9 chairs is:
[tex]9 * 8 * 7 * 6 * 5 * 4 = 60,480[/tex]
So there are 60,480 ways to seat 6 people in a row of 9 chairs.
To count the number of ways 6 people can be seated in a row of 9 chairs, we can use the multiplication principle of counting.
First, we consider the number of choices for the first person. Since there are 9 chairs and the order in which the people are seated matters, there are 9 choices for the first person. Once the first person is seated, there are 8 chairs remaining for the second person to choose from, since one chair is already taken. Therefore, there are 8 choices for the second person. Continuing in this way, there are 7 choices for the third person, 6 choices for the fourth person, 5 choices for the fifth person, and 4 choices for the sixth person.
To find the total number of ways to seat 6 people in a row of 9 chairs, we multiply the number of choices at each step together. Hence, the total number of ways is:
[tex]9 * 8 * 7 * 6 * 5 * 4 = 60,480[/tex]

What is the solution to this equation? -2x + 15 = 30
After simplifying we get, the solution to the equation as -2x + 15 = 30 is x = -7.5.
To solve the equation -2x + 15 = 30, we need to isolate the variable x on one side of the equation. We can do this by performing the same operation on both sides of the equation to maintain its balance.
First, we will subtract 15 from both sides of the equation to get:
-2x + 15 - 15 = 30 - 15
Simplifying the left-hand side and the right-hand side of the equation, we obtain:
-2x = 15
Next, we will divide both sides of the equation by -2 to isolate x:
-2x/-2 = 15/-2
Simplifying, we get:
x = -7.5
Therefore, the solution to the equation -2x + 15 = 30 is x = -7.5.

The length of the rectangle is 63 cm and the Breadth of the rectangle is 12 cm, for this, we have to know something about rectangles.
What is a rectangle?Rectangle, It is a plane shape, as opposed to a square, with four(4) straight sides and four(4) right angles, particularly one(1) with uneven neighboring sides.
Square, A square is a regular quadrilateral in Euclidean geometry, which means that it has four(4) equal(same) sides and four(4) equal angles. It can alternatively be explained as a rectangle with two(2) neighboring sides that are of equal(same) length.
Given, Perimeter = 150 cm, Length, l = 5b+3 , Breadth = b
150 = 2(5b + 3 + b)
150 = 2(6b +3)
6b +3 = 75
6b = 72
b = 12 cm, So l = 63 cm (By putting the b value in the l equation

When his first child was born, a father put $3000 in a savings account that pays 4% annual interest, compounded quarterly. How much will be in the account on the child's 18th birthday? Answer rounded to the whole number
Answer:
$6141
Step-by-step explanation:
We can use the formula for compound interest to find the amount in the account after 18 years:
A = P(1 + r/n)^(nt)
Where:
A = the amount in the account after 18 years
P = the principal amount (initial deposit) = $3000
r = the annual interest rate = 4% = 0.04
n = the number of times the interest is compounded per year = 4 (quarterly)
t = the time in years = 18
Plugging in these values, we get:
A = 3000(1 + 4%/4)^(4*18)
A = 3000(1.01)^72
A = 3000*2047
A = 6141
Rounding to the nearest whole number, we get:
A = $6141
Therefore, there will be $6141 in the account on the child's 18th birthday.
