All questions are solved using BODMAS rule.
BODMAS stands for Brackets, Orders (of operations), Division, Multiplication, Addition, and Subtraction. It is a commonly used acronym in mathematics to remember the order in which mathematical operations should be performed. When solving mathematical expressions, operations within brackets should be done first, followed by any exponents or roots.
Next, perform any divisions or multiplications from left to right, followed by any additions or subtractions from left to right. This order ensures that the expression is evaluated correctly and avoids confusion or errors.

Aadan and Chinyelu viit the market in Gao to buy an Azawakh, a breed of dog that i popular for guarding ancient Mali village. When Aadan' dog wa a puppy, it weighed `8` kg, which i `30\%` of it current adult weight. What i the current weight of Aadan’ dog?
Write an equation in which `x` repreent the current weight of Aadan' dog
The current weight of Aadan's dog is approximately 26.67 kg.
What is weight ?
Weight is a measure of the force of gravity on an object. The weight of an object is equal to the force exerted on the object by gravity. The weight of an object is typically measured in units of force such as newtons (N) or pounds (lb). On Earth, the weight of an object is equal to its mass multiplied by the acceleration due to gravity, which is approximately 9.8 m/s².
Let's call the current weight of Aadan's dog as "W".
As per the information given,
Aadan's dog was a puppy and it weighed 8 kg which is 30% of it's current adult weight.
So, 8kg = 30/100*W
We can find the current weight of Aadan's dog by solving the equation above:
8 = 30/100W
8 = 3/10W
8 = 0.3W
W = 8/0.3
W = 8/(3/10)
W = 8(10/3)
W = 8*3.333
W = 26.666 kg ( approx 26.67 kg)
So the current weight of Aadan's dog is approximately 26.67 kg.

The percentage of commuters that travel more than 45 minutes is 90%.
What is percentage ?
A percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%" and is used to express a proportion or rate as a part of a whole. Percentages can be used to compare different quantities or to express how much one quantity has changed relative to another.
The percentage of commuters that travel more than 45 minutes is the quotient of the commuters that travel more than 45 minutes and the total number of surveyed commuters.
So, we have ,
Percentage = [tex]\frac{450}{500}%Percentage[/tex] =500450
Divide 450 by 500
Percentage = 0.9 Percentage=0.9
Express as percentage
Percentage = 90 Percentage=90%
Hence, the percentage of commuters that travel more than 45 minutes is 90%.

If f(x)= 2x2 + x - 7 and g(x)= x + 5, then evaluate g(f(3)).

Step-by-step explanation:
This would be your functions: [tex]\displaystyle{f(x)=2x^2+x-7}[/tex] and [tex]\displaystyle{g(x)=x+5}[/tex]. In order to evaluate g(f(3)), we must find the value of f(3) first which we can find by substituting x = 3 in the f(x).
[tex]\displaystyle{f(3)=2(3)^2+3-7}\\\\\displaystyle{f(3)=2\cdot 9 - 4}\\\\\displaystyle{f(3)=18-4}\\\\\displaystyle{f(3)=14}[/tex]
Therefore, g(f(3)) is basically equal to g(14), we substitute x = 14 in the g(x).
[tex]\displaystyle{g(f(3))=g(14)=14+5 = 19}[/tex]
Hence, g(f(3)) is 19.
How do you express your answer as a polynomial in standard form?.
The standard form of polynomial is to write the polynomial so that the term with the highest power of the variable comes first, followed by the other terms in order of descending powers of the variable.
A polynomial in standard form requires that the polynomial be written in descending order of exponents. Polynomials are written in standard form for ease of computation. A polynomial is in its canonical form when it is expressed with the highest order term first, followed by the higher order terms, and so on. For example: 14x⁴ - 5x³ - 11x² - 11x + 8. You can see that in this standard form polynomial, the exponents are ordered in descending powers. These algebraic equations are called polynomials. Procedure for writing polynomials in standard form:
Write the terms Make the groups of all similar terms.The highest exponent write the as first term.Write the rest of the terms with small exponents in descending order.Write the constant term.The normal form polynomial of degree 'n' is : aₙxⁿ + aₙ₋₁ x⁽ⁿ⁻¹⁾ + ... + a₁ x + a₀
Let us assume a polynomial, p(x) = x² + 8x - 9 + 7x³ - 6x + x⁴ , using the above steps we can write the standard form of p(x).
x² + 8x - 9 + 7x³ - 6x + x⁴ x² - 9 + 7x³ - 6x + 8x+ x⁴ = x² - 9 + 7x³+ 2x + x⁴x⁴ + 7x³ + x² + 2x - 9 ( standard form)To learn more about Standard form polynomial, refer:

Consider the function f(x)=x^3-1. Which of the following functions is f^-1(x)?
The inverse function of f(x) = x^3 - 1 is f^-1(x) = (x + 1)^(1/3).
What is the inverse of a function?
An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function that gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.
The inverse of a function f(x) is denoted as f^-1(x), and it is defined as the function that "undoes" f(x).
To find the inverse of a function, we need to swap the roles of x and y, and then solve for y in terms of x.
Given f(x) = x^3 - 1, the inverse function f^-1(x) is the function such that:
f(f^-1(x)) = x
f^-1(f(x)) = x
So we need to solve for x in terms of y.
x^3 - 1 = y
x = (y + 1)^(1/3)
Therefore, the inverse function of f(x) = x^3 - 1 is f^-1(x) = (x + 1)^(1/3).

The degree measure of each angle in the triangle are:
m angle l = 18.4
m angle J = 57.6
m angle K = 93
What is the Degree Measure?
The degree measure, also known as an angle measure, is a way to quantify the size of an angle in mathematics. The degree measure of an angle is typically represented by the symbol "degrees" (°) or simply "deg" and it is a unit of measurement.
In a triangle, the degree measure of all angles add up to 180 degrees. Therefore, we can use this property to find the degree measure of each angle in the triangle.
m angle l = (x + 5) deg
m angle J = (4x + 7) deg
m angle K = (7x) deg
So we can use the following equation:
m angle l + m angle J + m angle K = 180
(x + 5) + (4x + 7) + (7x) = 180
12x + 19 = 180
12x = 161
x = 13.4
Hence, the degree measure of each angle in the triangle are:
m angle l = (x + 5) deg = (13.4 + 5) = 18.4
m angle J = (4x + 7) deg = (413.4 + 7) = 57.6
m angle K = (7x) deg = (713.4) = 93

sum of two numbers is 95.theother by 15 find the numbers?
Answer:
The two numbers are 40 and 55.
Step-by-step explanation:
Let one of the numbers be x.
Then the other number is 95 - x.
If we assume x to be larger among two of them,
⇒ x - (95 - x) = 15 (as one exceeds the other by 15)
⇒ 2x = 15 + 95
⇒ x = 110 / 2 = 55
The other number is (95 - x) which is 95 - 55 = 40
Thus, the two numbers are 40 and 55

Two points on your graph is (2,2), and (6,4). You would take the second y which is 4 and subtract it from the first y which is 2. (4-2 = 2). Then you take the second x (6) and subtract it from the second y (2). (6-2 = 4). Now that you have the change and x over the change in y. you divide the top number by the bottom number.
