Answer:
Given that RS bisects MO at N, we know that:
RN = RO (by definition of a bisector)
MN + NO = MO (by the angle bisector theorem)
Given that MN = 5x + 8 and NO = 10 + 3x, we can substitute these values into the second equation to find the value of x.
MN + NO = MO
(5x + 8) + (10 + 3x) = MO
8x + 18 = MO
Now we can use the first equation to find the value of x.
RN = RO
5x + 8 = 10 + 3x
3x = 2
x = 2/3
Therefore, the value of x is 2/3.
LMNO is a parallelogram. If NM = x + 12 and OL = 2x + 8, find the value of x and then find NM and OL.
The value of the sides, NM and OL are 16 and 8 respectively
How to determine the value
To determine the value of x, we have the note the properties of a parallelogram.
The properties of a parallelogram includes;
Opposite sides of a parallelogram are parallelOpposite sides of a parallelogram are congruentOpposite angles of a parallelogram are congruentInterior angles are supplementaryEach diagonal of a parallelogram divides it into two congruent trianglesThe diagonals of a parallelogram bisect each other at right angleThen, we have;
NM = OL
substitute the values
x + 12 = 2x + 8
Now, collect like terms
x = 4
NM = 4 + 12 = 16
OL = 16
Hence, the value are 4 and 16

a marble is selected at random 3 times from a bag of 2 green marbles, 2 blue marbles, and 2 red marbles. the selected marble is replaced each time. what is the probability that at least 1 of the selections is blue?
The odds of choosing a red and a blue are 6/20 (4/20), or 3/5.
What is meant by probability?The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true.A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty. Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability. The likelihood that something will happen is known as probability. The number of possible outcomes is divided by the total number of possible outcomes to determine probability.The balls in the bag are unaware of what was drawn the first time because the two choices are separate.
Six of the 20 pebbles in the bag are red. The odds of selecting a red are 6/20.
Four of the 20 pebbles in the bag are blue. Picking a blue one has a 4/20 chance.
Multiplying the odds of each event will yield the likelihood of two independent events.
The likelihood of selecting a red followed by a blue is 6/20 (4/20), or 3/5.

for a random sample of 100 people, what is the probability that the sample mean will be within 5 points of the population mean
The probability that the sample mean will be within 5 points of the population mean is 0.95 or 95%
Central Limit TheoremThe Central Limit Theorem (CLT), a foundational idea in statistics, holds that, regardless of the underlying population distribution, the distribution of the sample means will be about normal given a big enough sample size. The CLT is crucial because it enables us to draw conclusions about a population based on a sample, even when the population is not normal.
According to the CLT, as the sample size grows, sample means will approach population means and their standard deviations will fall. The standard error, also known as the standard deviation of the sample means, is calculated by dividing the standard deviation of the population by the square root of the sample size.
According to the Question
The sample mean for a random sample of 100 individuals is most likely to be within 5 points of the population mean. The distribution and standard deviation of the population, however, would determine the precise likelihood. The standard error may be used to determine a confidence interval for the population mean if the population standard deviation is known. A 95% confidence interval is frequently used, which is equivalent to 1.96 standard deviations from the mean. In this instance, especially with a large sample size, there is a good likelihood that the sample mean will be within 5 points of the population mean.

15 foot ladder leaning agaisnt a building touches the wall 12 feet above the ground how far from the building is the bottom of the ladder
The bottom of the ladder is 9 feet from the wall.
Using the Pythagorean Theorem, we can calculate the distance from the wall. The Pythagorean Theorem states that for a right triangle, the sum of the squares of the sides is equal to the square of the hypotenuse. In this case, the hypotenuse is 15 feet and the side adjacent to the wall is 12 feet.
The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.
We can solve for the distance from the wall (a). a^2 = c^2 - b^2, so a^2 = 15^2 - 12^2, which equals a^2 = 225 - 144, so a^2 = 81. Taking the square root of both sides, a = 9 feet.
Therefore, the bottom of the ladder is 9 feet from the wall.

We have the formula A = 1/2(a+b)h
Let's identify all variables
A = 24
a = 9
b = 7
h = ?
Lets plug all that in:

Elle wants to spend at most Php80 on dairy products. Each liter of goat milk costs
Php130 and each liter of cow's milk costs Php65. Find the possible number of each dairy product
Elle can buy maximum 0.6 liters of goat milk and 1.2 liters of cow's milk.
What System of linear inequalities?
A system of linear inequalities is similar to a system of linear equations, except that it is made up of inequalities rather than equations. To represent scenarios with various restrictions, systems of linear inequalities are utilized.
Let x be the number of liters of goat milk and y be the number of liters of cow's milk that Elle wants to buy. We know that:
x + y ≤ 80 (because Elle wants to spend at most Php80)
130x + 65y ≤ 80 (because each liter of goat milk costs Php130 and each liter of cow's milk costs Php65)
This is a system of linear inequalities, and the solution set is the set of all possible combinations of x and y that satisfy both inequalities.
The inequality 130x + 65y ≤ 80 represents a line in the plane, and the inequality x + y ≤ 80 represents a region that is "bounded" by this line.
The solution set for the inequalities are x <= 0.6 and y <= 1.2.
So, Elle can buy maximum 0.6 liters of goat milk and 1.2 liters of cow's milk.

what are the dimensions of a rectangular tract of land when it’s perimeter is 44 kilometers and it’s area is 120 square kilometers
Answer:
The dimensions of the rectangular tract of land with a perimeter of 44 kilometers and an area of 120 square kilometers are:
Length = 10 kilometers
Width = 12 kilometers
Explanation: To find the dimensions of a rectangular tract of land when its perimeter and area are known, you can use the formulas:
Perimeter = 2(length + width)
Area = length * width
We know that:
Perimeter = 44 kilometers
Area = 120 square kilometers
So, we can use these values to set up the following equation:
44 = 2(length + width)
And we can solve for length and width.
44 = 2(length + width)
22 = length + width
And now we know that the sum of the length and width of the rectangular tract is 22 kilometers.
Now we have to use the area formula:
Area = length * width
120 = length * width
We can use the value we have for the sum of the length and width to find either the length or the width of the rectangular tract.
For example, we can use the equation:
length = 22 - width
And substitute it into the area equation:
120 = (22 - width) * width
And then we can solve for width:
120 = 22 * width - width^2
width^2 - 22 * width + 120 = 0
We can use the quadratic formula to solve for width.
width = (22 +/- sqrt(22^2 - 4 * 1 * 120))/ 2
So,
width = (22 +/- sqrt(484 - 480))/ 2
width = (22 +/- sqrt(4))/ 2
width = (22 +/- 2)/ 2
width = (24)/ 2
width = 12
So, the width of the rectangular tract is 12 kilometers.
And we can use the equation:
length = 22 - width
to find the length
length = 22 - 12 = 10
So, the dimensions of the rectangular tract of land with a perimeter of 44 kilometers and an area of 120 square kilometers are:
Length = 10 kilometers
Width = 12 kilometers

first complete these equations: 160 = ?W + ? L ; W = L - ?
The dimensions of the new practice court is 45.5 feet by 29.5 feet.
The equations should be completed as 160 = 2W + 2L; W = L - 16
How to calculate the perimeter of a rectangle?Mathematically, the perimeter of a rectangle can be calculated by using this mathematical expression;
P = 2(L + W) or P = 2L + 2W
Where:
P represents the perimeter of a rectangle.L represents the length of a rectangle.W represents the width of a rectangle.Since the width of the rectangular lot is 16 feet less than the length, we have:
W = L - 16
Substituting the given parameters into the perimeter formula, we have;
160 = 2L + 2W
160 = 2(L - 16) + 2L
160 = 2L - 32 + 2L
160 = 4L - 32
4L = 182
L = 45.5 feet.
For the width, we have:
W = L - 16
W = 45.5 - 16
W = 29.5 feet.

What is the constant of proportionality? What does it represent?
Answer:
In Explanation
Step-by-step explanation:
The constant of proportionality is a value that relates two variables that have a proportionate relationship. It is often represented by the letter "k".
For example, if two variables x and y are directly proportional, their relationship can be represented by an equation of the form y = kx, where k is the constant of proportionality. In this equation, the value of k represents the ratio of y to x and it is constant, meaning that it does not change as the values of x or y change.
In physics, the constant of proportionality also appears in many mathematical models of natural phenomena, such as Hooke's law (F = km) which relates the force applied on an object (F) to its displacement (x) with a spring constant (k), and Ohm's law (V = IR) which relates the voltage (V) across a resistor to the current (I) flowing through it with a resistance constant (R).
The constant of proportionality can have different units of measure depending on the context and is used to make quantitative predictions about the relationship between the variables. In some cases, it can be used to determine the behaviour of a system or physical process.

a local ice cream store is analyzing the day's sales. each serving came in either a cup or a cone, but not both, and the ratio of servings to cups was 7:47:47, colon, 4. what was the ratio of servings to cones?
The ratio of servings to cones is 47:4.
In mathematics, a ratio is a way of comparing two or more values. It is usually represented as a fraction, with the values being separated by a colon (:). For example, if you have 7 apples and 4 oranges, the ratio of apples to oranges would be 7:4. This can also be written as 7/4 or 1.75. Ratios can also be written as a decimal or a percentage. Ratios can be used to compare quantities, sizes, or measurements in different units.
If the ratio of servings to cups is 7:47:47:4, that means for every 7 servings, there are 47 cups.
Since the servings came in either a cup or a cone, but not both, the ratio of servings to cones is the remaining portion of servings that are not accounted for in the ratio of servings to cups.
So, it's 7 servings + 47 cups = 47 servings + 4 cups.
Therefore, the ratio of servings to cones is 47:4.
