What is simplification of algebraic expression?
At first it is important to know about algebraic expression. Algebraic expression consist of numbers and variable connected by addition, subtraction, multiplication, division.
Simplification of algebraic expression is the process of calculating the algebraic expression into lower form by combining all the like terms together. Here, BODMAS rule is used. B stands for bracket, O stands for of, D stands for division, M stands for multiplication, A stands for addition, S stands for subtraction.

In triangle ABC, angle B is one-quarter of angle A and angle C is two fifth of angle A. If the size of angle A is (x- 10)°. Form an equation in x and hence calculate the angle of triangle ABC to the nearest degree.
When in triangle ABC, angle B is one quarter off angle B and angle C is two fifth of angle A and the angle A is (x-10) degrees, then the ∠A, ∠B and ∠C are 109 degrees, 27 degrees and 44 degrees respectively
The ∠A = (x-10) degrees
Angle B is one-quarter of angle A
∠B = (1/4)×(x-10)
= (1/4)x - (5/2)
= 0.25x-2.5
The angle C is two fifth of angle A
∠C = (2/5)(x-10)
= (2/5)x - 4
= 0.4x-4
We know sum of the angles in a triangle is 180 degrees
Then,
∠A + ∠B + ∠C = 180
Substitute the values in the equation
(x-10) + 0.25x-2.5 +0.4x-4 = 180
1.65x-16.5 = 180
1.65x = 196.5
x ≈ 119
∠A = (x-10)
= 119-10
= 109 degrees
∠B = 0.25x-2.5
= 0.25×119-2.5
≈ 27 degrees
∠C = 0.4x-4
= 0.4×119-4
≈ 44 degrees
Hence, when in triangle ABC, angle B is one quarter off angle B and angle C is two fifth of angle A and the angle A is (x-10) degrees, then the ∠A, ∠B and ∠C are 109 degrees, 27 degrees and 44 degrees respectively

What are functions?
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given: g(x) = 3x
To evaluate : The function x= - 2, 0, 5.

How to illustrate the information?A vertex (plural vertices) in geometry is the intersection of two straight lines. Three line segments come together to form a triangle. The ends of a triangle's three sides meet at three separate points in a plane to form the triangle, which has three sides with two endpoints each. The vertices of a triangle are the three distinct intersecting points or corners.
Congruent triangles are triangles that are precisely the same size and shape. The word congruent has the sign. When the three sides and three angles of one triangle match the same dimensions as the three sides and three angles of another triangle, two triangles are said to be congruent.

the total consumption of fruit juice in a particular country in 2006 was about 2.28 times 10 squared 9 gallons. The population of that country that year was 3 times 10 squares 8 what was the average number of gallons consumed per person in the country 2006
The average consumption of the fruit juice would be 7.6 gallons for the year 2006.
What do you understand by average consumption?Average consumption is derived by dividing the total measured consumption of that municipal service by that consumer during the three months before by three. It refers to the average consumption of a consumer of a municipal service during a certain time.
How is the average consumption determined?Utilizing the total of quantities consumed or dispersed over a period of time, typically 12 months, the average monthly consumption can be computed. The average number of units used each month is known as average monthly consumption, stock-outs corrected (CA).
Total consumption of the fruit juice in 2006=2.28x109 gallons.
Total population of the country in year 2006=3x108
Average Consumption=(2.28x109)/(3x108)
= 7.6 gallons

me Give example of 6 types of factoring polynomials with Solution
Answer:
1 Greatest Common Factor
We have to find out the greatest common factor, of the given polynomial to factorise it. This process is nothing but a type of reverse procedure of distributive law.
2. Grouping
This method is also said to be factoring by pairs. Here, the given polynomial is distributed in pairs or grouped in pairs to find the zeros.
3. Using Identities
The factorisation can be done also by using algebraic identities. The most common identities used in terms of the factorisation are:
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
a2 – b2= (a + b)(a – b)
4. Zero Factor Property :The Zero Factor Property (also called the Zero Product Property) says that if the product of two quantities is zero, then at least one of those quantities is zero. The only way to get a product equal to zero is to multiply by zero itself.
5. Greatest Common Factor (GCF) Method:
This is almost always the first method applied to factoring polynomials. Look at all of the terms and see if they all have something in common that can be removed.
6. Sum or Difference in Two Cubes

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
it is already known that Oris has to move 7 squares (because 3 + 4 = 7), yet she has another 6 sets of possibilities because a dice has 6 facets.

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 20.8 years; the standard deviation is 3.1 years.
Use the empirical rule (68 - 95 - 99.7%) to estimate the probability of a gorilla living longer than 23.9 years
The probability of a gorilla living less than 23.9 years is 0.84 (84%) if the lifespans of gorillas in a particular zoo are normally distributed.
How does probability work?A probability is also called as a numerical representation of the likelihood or chance that any kind of specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities. Probability refers to potential.
Any random event's occurrence is the exact subject of this area of mathematics. The range of the value varies from 0 to 1. Mathematics has been incorporated probability to forecast the likelihood of various types of events.
How is probability determined?The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas.
We need to find the z-score herein of 23.9 years in the kind of standard normal distribution of the lifespans of gorillas in this particular zoo.
z score can be further be calculated using the equation
z = (X-M)/s
and it has been given that X is 23.9 years
M is also called the average gorilla life (20.8 years)
s is given as the standard deviation (3.1 years)
Thus, putting up the values, we have
Z = 1
The Empirical rule that is present here states that 68% of the total lifespans lie within 1 standard deviation from the other mean.
Then Half of it, 68/2 = 34 % lies right side of 1 standard span of the mean.
Since this lifespan is less than mean is 50%, 50%+34% =84% lies less than total z-score 1, that is the probability of a gorilla living less than 23.9 years.

A unicycle wheel has a diameter of 24 inches.

If the wheel revolves 3 times clockwise, approximately how far does the unicycle travel? (Use 3.14 for π.)
The distance travelled by the unicycle is 226.08 inches.
What is the distance travelled?The first step is to determine the circumference of the wheel of the unicycle. A circle is a bounded figure which points from its center to its circumference is equidistant. The circumference of a circle is the distance round the circle.
Circumference of a circle = 2πr
Where:
π = pi = 3.14 r = radius = diameter / 2 = 24 / 2 = 12 inches3.14 x 2 x 12 = 75.36 inches
The next step is to multiply the circumference of the unicycle by the number of revolutions the tire made.
Distance travelled = 3 x 75.36 inches = 226.08 inches
