If BE = 10x - 12 and EF = 2x, Find AC
The length of AC is 12.
What are Arithmetic operations?Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.
Given is a line.
A, B, C, D, E and F are equally spaced on the line.
Given that, EF = 2x
This means that distance between each of the point is 2x.
AB = 2x, BC = 2x, CD = 2x, and DE = 2x
Given BE = 10x - 12
BE = BC + CD + DE
= 2x + 2x + 2x
= 6x
So, 10x - 12 = 6x
10x - 6x = 12
4x = 12
x = 3
Now, we have to find AC.
AC = AB + BC
= 2x + 2x
= 4x
= 4 × 3
= 12
Hence AC is 12.

Therefore, the length of the arc intercepted by the central angle is 56.52 cm (rounded to two decimal places).
What is arc?In geometry, an arc is a part of a circle. Specifically, it is a portion of the circumference of a circle. An arc can be defined by two endpoints and all the points on the circle's circumference between those endpoints. Arcs are commonly measured in degrees, just like angles. A full circle has 360 degrees, so a semicircle has 180 degrees, and so on. The length of an arc depends on the size of the circle and the size of the central angle that intercepts it. Arcs are important in many applications of geometry, such as in navigation, architecture, and engineering. They are also used in trigonometry and calculus to study functions that involve circular or periodic behavior.
Here,
We can use the formula for the length of an arc of a circle to find the length of the arc intercepted by a central angle. The formula is:
Length of arc = (Central angle / 360) x (2 x π x radius)
where π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the central angle measures 270 degrees and the radius of the circle is 12 cm. We can substitute these values into the formula to get:
Length of arc = (270 / 360) x (2 x π x 12)
Length of arc = (3/4) x (2 x 3.14 x 12)
Length of arc = 0.75 x 75.36
Length of arc = 56.52 cm

What is data in math?Data is the raw information that can be collected and analyzed to provide insights. It is the foundation of decision-making and can be used to identify trends, patterns, and relationships. Data can come from many different sources, including surveys, databases, and software applications. Data can be qualitative or quantitative, static or dynamic, structured or unstructured, and can be used to inform decisions, inform policy, and inform research. Data can also be used to make predictions, monitor performance, and improve efficiency.
This suggests that the competition between the teams is relatively balanced, and that no team is significantly outperforming the others in terms of number of wins. This could indicate that the teams are of about equal skill level, or that the schedule for each team is balanced enough that no team has an advantage over the others.

Debra will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $47.96 and costs an additional $0.19 per mile driven. The second plan has an initial fee of $53.96 and costs an additional $0.15 per mile driven. How many miles would Debra need to drive for the two plans to cost the same?
By answering the above question, we may state that Debra would thus function need to travel 150 miles for the price of the two plans to be the same.
what is function?Mathematicians research numbers, their variants, equations, forms, and related structures, as well as possible locations for these things. The relationship between a group of inputs, each of which has a corresponding output, is referred to as a function. Every input contributes to a single, distinct output in a connection between inputs and outputs known as a function. A domain, codomain, or scope is assigned to each function. Often, functions are denoted with the letter f. (x). The key is an x. There are four main categories of accessible functions: on functions, one-to-one capabilities, so many capabilities, in capabilities, and on functions.
The starting charge and the cost per mile would be added together for the first plan's total cost:
Costs for plan 1 total 47.96 plus 0.19x.
The first charge and the cost per mile would be added together for the second plan's total cost:
Plan 2's overall cost is 53.96 plus 0.15x.
Set the two total cost expressions equal to one another and solve for x to get how many miles Debra would need to go for the two plans to be the same in price:
47.96 + 0.19x = 53.96 + 0.15x
0.04x = 6
x = 150
Debra would thus need to travel 150 miles for the price of the two plans to be the same.

Electricity bills in a certain city have mean $ 106.27 . Assume the bills are normally distributed with standard deviation $ 17.15 . Find the value that separates the lower 40 % of the bills from the rest.
Write only a number as your answer. Round to two decimal places (for example: 42.81). Do not write any units.
Answer:
Step-by-step explanation:
To find the value that separates the lower 40% of the bills from the rest, we need to find the z-score corresponding to the 40th percentile of the standard normal distribution, and then use this z-score to find the corresponding value in the distribution of electricity bills.
Using a standard normal distribution table or a calculator, we can find that the z-score corresponding to the 40th percentile is approximately -0.25.
To find the corresponding value in the distribution of electricity bills, we can use the formula:
z = (x - mu) / sigma
where z is the z-score, x is the corresponding value in the distribution, mu is the mean, and sigma is the standard deviation.
Rearranging this formula to solve for x, we get:
x = mu + z * sigma
Substituting the given values, we get:
x = 106.27 + (-0.25) * 17.15
x = 101.63
Therefore, the value that separates the lower 40% of the electricity bills from the rest is approximately $101.63.

Neither of the given points is a solution to the system of linear inequalities.
What does solution to the system of linear inequalities mean ?
A system of linear inequalities is a set of two or more linear inequalities with the same variables. This system consists of two linear inequalities, each involving the variables x and y, and each inequality uses one of the inequality symbols.
The solution to a system of linear inequalities is the set of values for the variables that satisfy all the inequalities in the system simultaneously. This solution can be represented graphically as the region of the coordinate plane that satisfies all the inequalities in the system.
Check the given points whether they are solutions to the system of linear inequalities or not :
Substitute the x and y values of each point into both inequalities and check if they are true.
(a) (-4,1) :
y ≤ -3x - 2
1 ≤ -3(-4) - 2
1 ≤ 10
This is false, so (-4,1) is a not solution to the first inequality.
y > x - 2
1 > -4 - 2
1 > -6
This is true, so (-4,1) is a solution to the second inequality.
Since (-4,1) is a solution to only one of the inequalities and not both, it is not a solution to the system of linear inequalities.
(b) (2,2):
y ≤ -3x - 2
2 ≤ -3(2) - 2
2 ≤ -8
This is false, so (2,2) is not a solution to the first inequality.
y > x - 2
2 > 2 - 2
2 > 0
This is true, so (2,2) is a solution to the second inequality.
Since (2,2) is a solution to only one of the inequalities and not both, it is not a solution to the system of linear inequalities.
Therefore, neither of the given points is a solution to the system of linear inequalities.

What is area?Area is a measure of the amount of space inside a two-dimensional (2D) shape or figure. It is usually measured in square units, such as square meters (m²) or square centimeters (cm²). The area of a shape is calculated by multiplying the length of one side or dimension of the shape by the length of another side or dimension. The resulting value represents the total number of square units that are contained within the shape. Area is an important concept in mathematics and is used in various fields, such as geometry, physics, and engineering. It helps in measuring and comparing the sizes of shapes and figures, and in determining how much material is needed to cover or fill a certain area.
Here,
The area of the base can be calculated using the dimensions of the aquarium.
Let's assume that the aquarium has a rectangular base with length L, width W, and height H. Then, the area of the base of the aquarium can be calculated as:

What is one change you can make to one value in Pedro's plan to ensure that Pedro meets his
daily running goal? Justify your response.
One change that Pedro can make to his plan to ensure that he meets his daily running goal is to increase the estimated number of steps per mile.
How would this help meet the running goal?If Pedro overestimates the number of steps in a mile, he will end up taking more steps than he initially planned for, which can help him reach his daily goal.
For example, if Pedro increases his estimate from 2,000 steps per mile to 2,500 steps per mile, he will need to run approximately 4 miles per day to reach his goal of 10,000 steps. This will make it more likely for him to reach his daily goal within the 4 hours of running over the 5 days.
Alternatively, Pedro can increase his running speed to cover more distance in a shorter period of time. For instance, if he increases his running speed from 6 miles per hour to 8 miles per hour, he will need to run for only about 2.5 hours per day to reach his goal of 10,000 steps.

where a = 5
area of the cube = 6(5²)
= 6×25 = 150
Therefore, the surface area of the shape after area of cube such as = 150 has been removed from it ;
= 314-150
= 164.

Determine if the triangle pictured below is a right triangle.
(30 points)
Answer: Yes
Step-by-step explanation: Even though the sides might be different because there is little detail in this illustration, you actually have to predict, and if it looks as straight up as it is here, it counts as right. (Also, if you have a tool like a protractor, you could use that to measure it.)
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Aaron sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
38 visitors purchased no costume.
239 visitors purchased exactly one costume.
12 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a decimal to the nearest hundredth.
The probability that the next person will purchase no costume is 0.13.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The total number of visitors to the website in a single day is:
38 + 239 + 12 = 289
Of these visitors, we know that 38 purchased no costume.
Therefore, the probability that the next person to visit the website will also purchase no costume is:
38/289 = 0.13
Hence, the probability that the next person will purchase no costume is approximately 0.13, or 13% to the nearest hundredth.

69 and 5.6 x 10^5 expressed in scientific notation
The product of 69 and 5.6 x 10⁵ expressed in scientific notation is 3.864 x 10⁷.
Describe Scientific Notation?Scientific notation, also known as standard form, is a way of writing very large or very small numbers in a concise and convenient way. It expresses a number as the product of a decimal number between 1 and 10 (known as the coefficient) and a power of 10.
The general form of a number written in scientific notation is:
a × 10^n
where a is the coefficient, and n is an integer exponent that indicates the number of places the decimal point must be moved to obtain the original number.
To multiply numbers in scientific notation, we multiply their coefficients and add their exponents.
69 x 5.6 x 10⁵ = (6.9 x 10¹) x (5.6 x 10⁵)
= (6.9 x 5.6) x 10¹⁺⁵
= 38.64 x 10⁶
= 3.864 x 10⁷ (in scientific notation)
Therefore, the product of 69 and 5.6 x 10⁵ expressed in scientific notation is 3.864 x 10⁷.

The complete question is :
A corn plant will be killed by the aphids if the total number of aphids on the plant exceeds 2,000. If there are 50 corn plants in this field, will there be enough aphids after 3 weeks to completely destroy the plants?
There won't be enough aphids to completely harm the maize plants because 10,000 is less than 2,000 50 (the maximum number of aphids that can be on all the plants without killing them).
Application of linear equationTo determine if there are enough aphids to kill the corn plants, we need to know the total number of aphids on each plant after 3 weeks. Let's assume that on average, each plant has 200 aphids after 3 weeks.
Then, the total number of aphids in the field would be:
50 plants × 200 aphids/plant = 10,000 aphids
Since 10,000 is less than 2,000 × 50 (the maximum number of aphids that can be on all the plants without killing them), there will not be enough aphids to completely destroy the corn plants.

find the value of x. 6cm 4cm x = ? cm angle measures and segment lengths
The length of segment in the given circle x is 5 cm.
What is circleA circle is formed by all points in a plane that are at a particular distance from the centre. The radius of a circle is the separation between any point on the circle and its center.
Intersecting Secant-Tangent TheoremThe product of the measures of the secant segment and its external secant segment equals the square of the measure of the tangent segment if a tangent segment from a location outside the circle, secant segments are drawn.
In the circle shown, if
AB=6cm
AC=4cm and
CD=x?
According to tangent-secant relation:AC×AD=[tex]AB^{2}[/tex]
4(4+x)=[tex]6^{2}[/tex]
4+x=36/4
x=5
Hence, The length of segment in the given circle x is 5cm.
