One of the fundamental aspects of geometry is the construction of angles.

A shape known as an angle is created by two rays that have a common point (called a vertex). A protractor can be used to create a variety of angles. There are also ways to construct some angles without using a protractor, including 60°, 30°, 120°, 90°, and 45°. As a result, these angles can be created using a ruler and compass.

In geometry, construction is a key topic where we learn to construct angles, lines, and various shapes. We will learn how to create angles in this post using a protractor, compass, ruler, and pencil.

To draw an angle of 15 degrees using a pair of compass and ruler, follow these steps:

Place the point of the compass on the point where you want the vertex of the angle to be.

Adjust the compass to the desired width of the angle's rays.

Draw an arc that intersects both rays of the angle.

Using the ruler, draw a line from the vertex of the angle to the point where the arc intersects one of the rays.

Repeat step 4 for the other ray.

You should now have a 15-degree angle.

On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

Now, According to the question:

How do you find the B intercept form?

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line.

y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept. x and y represent the distance of the line from the x-axis and y-axis, respectively. The value of b is equal to y when x = 0, and m shows how steep the line is.

Step-by-step explanation:

Of 800 students in a university, 360, or 45%, live in dormitories. the 800 is an example of population size. Population size is a number that represents the total quantity of a particular group of items or people.

In this case, the population size is 800 students in a university. This population size is used to calculate the percentage of students who live in the dormitories. In this example, the percentage of students who live in the dormitories is 45% or 360 students.   Population size can be used to analyze different trends or patterns within a group of people.

For example, if the university wanted to determine the number of students who commute from home, they could use the population size of 800 students to calculate the percentage of students who commute from home. Similarly, the university could use the population size to calculate the percentage of students who live off-campus.   Population size can also be used to track changes over time.

For example, if the university wanted to determine if the number of students living in the dormitories had increased or decreased since last year, they could compare the current population size of 800 students with the population size from the previous year.

The dimension of the shipping box is : 6 , 7 and 2 ft.

Now, According to the question:

The given information is:

Width of shipping box is x

Length of shipping box is x+1

Height of shipping box is x-4

The volume is 84 cubic ft.

To find the dimensions of the box in feet.

The volume of a box is = width × length × height.

Plug all the values in above formula:

84 cubic ft. = x(x + 1) (x - 4)

84 cubic ft. = (x)(x+1)(x-4) = [tex](x)[/tex][tex](x^2-3x-4)[/tex] = [tex]x^3 - 3x^2 - 4x.[/tex]

Next, think of the factors of 84. 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84.

The value is x = 6.

Put the value x = 6

The linear equation that models the distance as a function of time is:

y = -65mi/h*x + 420mi

A general linear equation can be written as:

y = a*x + b

Where y is the distance, x is the number of hours, x is the slope or rate of change, and b is the y-intercept.

Here we know that the family traves at a constant rate of 65 mi/h, then that will be the value of the slope.

And the y-intercept will be equal to the initial distance that they need to travel, which is 420 miles, then the linear equation that represents the distance as a function of time is:

y = -65mi/h*x + 420mi

The reaction time for Joyce is given by the equation J = -0.1 seconds

The reaction time for Felix is given by the equation F = -0.4 seconds or 0.2 seconds

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the reaction time for Joyce is given by the equation J

Let the reaction time for Felix is given by the equation F

The average reaction time = 0 seconds

Now , the value of J = 0.1 seconds below the average reaction time

So , substituting the values in the equation , we get

The reaction time for Joyce J = 0 - 0.1 = -0.1 seconds

And ,

The difference between the reaction time of Joyce and Felix = 0.3 seconds

So , substituting the values in the equation , we get

J - F = 0.3

-0.1 - F = 0.3

Adding F on both sides of the equation , we get

F + 0.3 = -0.1

Subtracting 0.3 on both sides of the equation , we get

F = -0.4 seconds

And , F - J = 0.3

So , F - ( -0.1 ) = 0.3

F = 0.2 seconds

Answer:

To find the exact value of csc(theta) in simplest radical form, we first need to determine the coordinates of the point on the terminal side of the angle in standard position.

Since the terminal side passes through the point (-2,1), we know that the point is on the line y = 1. To find the exact value of csc(theta), we need to find the distance between the point (-2,1) and the origin (0,0). This distance is given by the expression sqrt((-2)^2 + 1^2) = sqrt(5).

Therefore, csc(theta) = 1/sin(theta) = 1/sqrt(5)

Sam built a circular fenced-in section for some of his animals.

The section has a circumference of 55 meters.

As we know that, the circumference of circle = 2πr. So,

2πr = 55

Now putting, π = 22/7

2 × [tex]\frac{22}{7}[/tex] × r = 55

Multiply by 7 on both side, we get

44 × r = 385

On solving the provided question we can say that by percentage 25% of 500 = 25/100 X 500 = 125 grams

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

-1/3 is the multiplicative inverse of -2 1 3

The multiplicative inverse of a number is the number that, when multiplied by the original number, equals 1. This concept is also sometimes referred to as the reciprocal of a number.

For example, the number 2 has a multiplicative inverse of 1/2 because 2 * (1/2) = 1. Similarly, the number 3 has a multiplicative inverse of 1/3 because 3 * (1/3) = 1.

It's important to note that not all numbers have a multiplicative inverse. For example, 0 does not have a multiplicative inverse because any number multiplied by 0 is 0.

In the case of -2 1 3, its multiplicative inverse is -1/3. This can be verified by multiplying -2 1 3 by -1/3:

(-2 1 3) * (-1/3) = - (2/3) = -2/3 + 1/3 + 2/3 = 1
