what is percentage ?A number or ratio that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the percent sign "%" is widely used to signify it. There are no dimensions to the percentage amount. Percentages are essentially fractions because they have a numerator of 100. Put the percent sign (%) next to a number to indicate that it is a percentage. For instance, you would score a 75% if you answered 75 out of 100 questions on a test correctly (75/100). Divide the money by the total to get percentages, then multiply the result by 100. The formula (value/total) x 100% is used to determine the percentage.

Answer: y = 40deg, x = 80deg
Step-by-step explanation:
1. Because we see that there are parallel lines in the triangle to the left, we know that two of the angles of that triangle are 50deg
2. using the fact that triangles have a total of 180deg we get x = 80deg
To solve for y, we also know that there are two angles in that triangle which are the same, and one of them is y, therefore 2y + 100deg = 180deg, meaning 7 = 40deg

what is linear equations?The algebraic equation y=mx+b is known as a linear equation. M serves as the y-intercept, and B serves as the slope. The previous clause has two variables, y and x, and is sometimes referred to as a "linear equation with two variables". Bivariate linear equations are those with two independent variables. The following are a few examples of system of equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation takes the form y=mx+b, with m denoting the slope and b denoting the y-intercept, it is referred to as being linear. The term "linear" refers to an equation having the form y=mx+b, where m stands for the slope and b for the y-intercept.

Sketch the area represented by g(x). g(x)t4 dt Then find g'(x) in two of the following ways (a) by using Part 1 of the Fundamental Theorem g(x) (b) by evaluating the integral using Part 2 and then differentiating g'(x)
The area represented by g(x) is the definite integral of g(x) with respect to t from t=0 to t=x:
g(x) = ∫(t^4) dt from 0 to x
To find g'(x) using Part 1 of the Fundamental Theorem of Calculus, we know that:
g'(x) = d/dx (∫(t^4) dt from 0 to x) = (t^4) evaluated at x = x^4
To find g'(x) using Part 2 of the Fundamental Theorem of Calculus, we can evaluate the integral:
g(x) = ∫(t^4) dt = (1/5)t^5 evaluated from 0 to x = (1/5)x^5
then take the derivative of g(x) with respect to x:
g'(x) = d/dx ((1/5) x^5) = (1/5) * 5x^4 = x^4
Both ways give the same result of g'(x) = x^4

Jackson digs a hole at a rate of 3/5 feet every 10 minutes. After digging for 40 minutes, Jackson places a plant in the hole that fills exactly 9/10 feet of the hole. Relative to ground level, what is the elevation of the hole after placing the plant in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
[tex]2 \, \dfrac{4}{25} \textrm{ ft}[/tex]
Step-by-step explanation:
First, solve for how many feet Jason has dug after 40 minutes:
[tex]\dfrac{\dfrac{3}{5} \textrm{ ft}}{10 \textrm{ min}} \times 40 \, \textrm{min} = 2 \dfrac{2}{5} \, \textrm{ft}[/tex]
So, the hole he has dug is 2 2/5 ft deep.
Next, we can solve for how deep the hole will be after placing a plant in by simply multiplying 9/10 by the depth of the hole dug.
[tex]2\, \dfrac{2}{5} \times \dfrac{9}{10} = \dfrac{12}{5} \times \dfrac{9}{10} = \dfrac{6 \times 9}{5 \times 5} = \dfrac{54}{25} = 2 \, \dfrac{4}{25} \textrm{ ft}[/tex]

The table shows monthly costs for two different internet service providers. What will be the difference in cost of the two plans after 18 months
Answer: 240
Step-by-step explanation:
The difference in cost between the two plans after 18 months is $240.
This is because the cost of Company A is consistently $35 more per month than that of Company B, which therefore would add up to $630 after 18 months.
The linear equation representing the cost of Company A is Y = 35X + 40, while the linear equation representing the cost of Company B is Y = 50X.
After 18 months, X would equal 18, and substituting this value into the two equations, we get the following for Company A:
Y = 35X + 40 Y = 35 * 18 + 40 Y = 630Meanwhile, for Company B, we get:
Y = 50X Y = 50 * 18 Y = 900The difference between these two values for different internet service providers is:
= $900 - $630 = $240This question should be provided with this following data:

Many students choose to take courses in statistics and computer science as elective. Suppose that in a certain university 41% take computer science, 48% take statistics, and 63% take at least one of these two courses. What is the probability a randomly selected student takes both a computer science and a statistics courses as elective? Round your answer to two decimal places.
The probability that a randomly selected student takes both computer science and statistics courses as electives is 0.26
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
We can use the formula for the probability of the intersection of two events:
P(A and B) = P(A) + P(B) - P(A or B)
where A and B are the events of taking computer science and statistics courses as electives, respectively.
Given:
P(A) = 0.41 (probability of taking computer science)
P(B) = 0.48 (probability of taking statistics)
P(A or B) = 0.63 (probability of taking at least one of these two courses)
So,
P(A and B) = 0.41 + 0.48 - 0.63 = 0.26
Therefore, the probability is 0.26, rounded to two decimal places.

What is the equation of the graph below?
The solution ax2 + bx + c = 0 can be solved using quadratic equation
x = (-b (b2 - 4ac))/2a to get the roots of the problem.
Quadratic equations: what are they?Just using equations x = ax2 + bx + c = 0 and a 0, a quadratic function is a 2nd polynomial problem in one variable. It is a third polynomial problem, hence the foundational theorem of algebra guarantees that there is least one solution. There may also be real or sophisticated solutions. The quadratic formula makes solving any quadratic equation easier for us. In order to solve this equation, we must first change its form to appear as ax2+bx+c=0, in which a, b, and d are the coefficients. Therefore, we add these coefficients to the method: (-b(b2-4ac))/ (2a).
Here,
The problem ax2 + bx + c = 0 can be solved using
the method x = (-b (b2 - 4ac))/2a to get the roots of the problem.
D = b² - 4ac provides the discriminant value. If D > 0, the equation has two genuine, separate roots.

What is the function notation?
Function notation is a way of writing mathematical functions using a specific syntax. A function is a rule that assigns a unique output to each input. In function notation, the function is represented by a letter, usually f, g, or h, followed by a variable in parentheses.
To find (f g)(x), we first need to find g(x) by substituting the value of x into the equation for g(x) = x^2 - 7:
g(x) = x^2 - 7
Next, we substitute the result of g(x) into the equation for f(x) = 2x + 1:
(f g)(x) = f(g(x)) = f(x^2 - 7) = 2(x^2 - 7) + 1
So the final result is (f g)(x) = 2x^2 - 14 + 1 = 2x^2 - 13

given
Now solve any problem for one variable. In the first equation, I'll find the value of x:
200mph = p - w
On both sides, add w:
p = 200mph Plus w
Now that we have the x from the first equation, we can use it to solve for w in the second equation:
200 mph + w + w Equals 300 mph
Add related phrases together for 300 mph: 200 mph plus two
200 mph on both sides are subtracted:
100mph = 2w
50 mph divided by two is w.
Therefore, the wind's speed is 50 mph.
To find the plane's speed, enter the value we just discovered back into either equation. I'll enter it into the first equation.

To find the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza, we need to find the percentage of people that liked pepperoni and the percentage of people that only liked cheese, and then subtract the smaller percentage from the larger percentage.
From the graph, we can see that 30 people liked pepperoni, 20 people liked mushrooms, 15 people liked sausage, and 10 people liked cheese and olives.
The total number of people Jimmy asked is 30+20+15+10 = 75
The percentage of people that liked pepperoni is 30/75*100 = 40%
The percentage of people that only liked cheese is 10/75*100 = 13.33%
The difference between 40 and 13.33 is 26.67%.
So, the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza is 26.67%.
