angles formed by a transversal worksheet answer key
A transversal is a third line that crosses two other lines.
Lines on a plane that do not intersect are considered parallel lines in geometry. It is referred to as being parallel when two straight lines in a plane do not cross at any point.
Eight distinct angles may be obtained by drawing two parallel lines, a line across them, and then another line through that.
A key mathematical ability that calls for conceptual comprehension and clarity is the angles form. Worksheets on angles generated by parallel lines and transversals provide a variety of activities and problems based on angles that can aid students in learning about angles.

Is the line y 3x 7 parallel or perpendicular to 3x 9y 9 explain your answer?
The slopes 3 and -1/3 are the opposites of one another. So the line y = 3x - 7 is perpendicular to line 3x + 9y = 9.
In the given question, we have to explain the line y = 3x - 7 is either parallel or perpendicular to 3x + 9y = 9.
The given equation is y = 3x - 7.
y = mx+ c is the line's equation in the slope-intercept form.
By comparing this to the preceding equation, we can determine that this line's slope is 3 and its y-intercept is -7.
Lines with equal slopes are said to be parallel. Lines that are perpendicular will have a slope product of -1.
3x + 9y = 9
We can write this equation as
9y = -3x + 9
Divide by 9 on both side, we get
y = -3/9 x + 9/9
y = -1/3 x + 1
Now the slope is -1/3 and y-intercept is 1.
Hence, the slopes 3 and -1/3 are the opposites of one another. So the line y = 3x - 7 is perpendicular to line 3x + 9y = 9.

For what value of k are the roots of the quadratic equation are real and equal?
The value of k for which the roots of the equation are real and equal is k = b^2/4a.
What is quadratic equation?A quadratic equation is an equation of the form ax^2 + bx + c = 0, where a, b, and c are constants and x represents an unknown. It is a type of polynomial equation, with the degree of the polynomial being 2. The solutions to a quadratic equation can be found using the quadratic formula, which involves taking the square root of the coefficient of x^2 and then subtracting the coefficient of x from both sides of the equation. Quadratic equations are commonly used in science, engineering, and mathematics.
The roots of any quadratic equation ax^2 + bx + c = 0 are real and equal when the discriminant, b^2 - 4ac, is equal to zero. This can be written as b^2 = 4ac, or b^2/4a = c. Therefore, the value of k for which the roots of the equation are real and equal is k = b^2/4a.

A city has a cone shaped building for storing salt and sand for icy roads. Each building has radius of 25 feet and height of 18 feet. Find the volume of the building. Use 3.14 for the pie
.
(A) 471 ft3
(B) 35, 325 ft3
(c) 11, 775 ft3
(D) 1413 ft 3
Answer: The volume of a cone is given by the formula: V = (1/3) * π * r^2 * h
Where:
V is the volume
π is 3.14
r is the radius
h is the height
So in this case, using the given values:
V = (1/3) * 3.14 * (25^2) * 18
V = (1/3) * 3.14 * 625 * 18
V = (625 * 18 * 3.14) / 3
V = 35,325 ft^3
So the answer is (B) 35,325 ft3

What are Mathematical operators??In mathematics, an expression is a group of numbers and operations. The components of a mathematical expression that perform an operation are as follows:
Operands: An operation uses operands, which are numbers. Depending on the type of operation, different terms are applied to the operands.
Given the total space for beach play = [tex]8\frac{2}{5}[/tex] square yards
[tex]8\frac{2}{5}[/tex] square yards = 42/5 square yards
and space for water = [tex]3\frac{1}{10}[/tex] square yards
[tex]3\frac{1}{10}[/tex] square yards = 31/10 square yards
let us assume the rest of the area for the sand
area of sand = total area - space for water
area of sand = 42/5 - 31/10
area of sand = (42(2) - 31)/0
area of sand = (84 - 31)/10

What are Angle of elevation and depression?Between the horizontal line and the line of sight, an angle called the angle of elevation is created. When the line of sight is upward from the horizontal line, an angle of elevation is created. In order to get the angle of elevation for an object at a distance of 10 units from the horizontal line (y=10) and 12 units from the observer w.r.t. the horizontal line (x=12), for instance, we write tan = 10/12, which can be simplified to tan = 5/6. The value of so obtained is tan-1 (5/6).Given the following parameters from the questions:
Height of the ramp = 10in
angle of elevation = 15degrees

100 ounces of pure chocolate is required to be included in 100 ounces of chocolate topping that is 50% chocolate to prepare a topping that is 75% chocolate.
Using the given equation to determine the number of ounces needed:
0.50 . 100 + 1.00x = 0.75(100 + x)
50 + 1.00x = 75 + 0.75x
50 - 75 = 0.75x - 1.00x
- 25= -0.25x

0.25x= 25
x= 25/0.25
x= (25. 100)/25

A decorator creates a scale drawing of a bedroom with a scale of 3 inches =5 feet. If the actual bedroom measures 24 feet long, how many inches long should the bedroom be in the scale drawing?
The bedroom should be 14.4 inches long in the scale drawing.
What is the proportion?
A proportion is an equation in which two ratios are set equal to each other.
If the scale of the drawing is 3 inches = 5 feet, that means that for every 3 inches on the drawing, it represents 5 feet in reality. To find how many inches the bedroom should be in the scale drawing, you can use the proportion:
(inches in scale drawing) / (feet in reality) = 3 inches / 5 feet
We know that the length of the actual bedroom is 24 feet. To find the length of the bedroom in the scale drawing, we can substitute 24 feet for the (feet in reality) in the proportion and solve for the (inches in scale drawing):
(inches in scale drawing) / 24 feet = 3 inches / 5 feet
Cross-multiplying gives:
(inches in scale drawing) = (24 feet)(3 inches / 5 feet) = 14.4 inches

What is Distance?
Length is measured in distance. For instance, the length of a road equals its distance.
The most popular units of measurement for distance in the metric system are millimeters, centimeters, meters, and kilometers.
A scalar quantity known as distance measures "how much ground an object has traversed" while moving. An object's total change in position is referred to as displacement, a vector variable that measures "how far out of place an object is."
How far did Sam run ?
Step1:
Dean ran 2.3 fewer kilometers than Sam. If Dean ran 6.8 km
Distance run by dean = 6.8 km
Distance run by dean = 2.3 fewer kilometers than Sam.
Let us assume that, distance run by same is s km
Step2:
Distance run by dean = s - 2.3
therefore,
s - 2.3 = 6.8
s = 6.8 + 2.3

How to Find the Simplest Form of a Fraction?If a fraction's top and bottom are whole numbers that are coprime to one another, it is said to be in its simplest form.It's easy to figure out how to simplify any fraction. By reducing the fraction's numerator and denominator by the greatest common factor that splits them both in half, we can simplify the numerator and denominator. The denominator and numerator should both remain whole numbers after division. Reducing fractions is another name for this fractional arithmetic procedure.Because the common component "c" is subtracted from both the numerator and the denominator, if the fraction is, for instance, ac/bc, then the simplified form of ac/bc will be a/b.ac/bc = a/b

What is an equation of the line that passes through the point (- 1/4 and is parallel to the line 2x y 1?
The equation of line passing through (-1, 4) and parallel to y = 2x + 1 is y = 2x + 6.
In the given equation, we have to find the equation of the line passing through (-1, 4) and parallel to y = 2x + 1.
The given equation of line is y = 2x + 1.
The given points (x(1), y(1)) = (-1, 4)
The equation of line in the slope intercept form is y = mx + c, where m is the slope of the line and c is the y-intercept of the line.
The slope of the given line y = 2x + 1 is m = 2, on comparing to the general equation of the line.
The equation of the line that passes through the point (x(1), y(1)) is:
y - y(1) = m(x - x(1))
Now putting the value in the formula
y - 4 = 2(x - (-1))
Now simplifying the equation,
y - 4 = 2(x + 1)
Using distributive property to simplify the equation
y - 4 = 2x + 2
Add 4 on both side, we get
y = 2x + 6
Hence, the equation of the line passing through (-1, 4) and parallel to y = 2x + 1 is y = 2x + 6.
