The sale price per sheet in this example is $12.60.
What is the discount?
A discount is a reduction in the price of a product or service that is offered by a seller to a buyer. It is a form of incentive that is used to encourage customers to purchase goods or services, often by making them more affordable or attractive.
To compare the two deals, we need to calculate the sale price per sheet for each deal.
In the previous example, the sale price per sheet was $15.00 after a 20% discount off the regular price of $18.00.
In this example, the sale price per sheet is 30% off the regular price of $18.00, so we can calculate the sale price per sheet as:
Sale price per sheet = Regular price per sheet - Discount amount
Sale price per sheet = $18.00 - (30% x $18.00)
Sale price per sheet = $18.00 - $5.40
Sale price per sheet = $12.60
Comparing the two deals, we can see that the sale price per sheet in this example is lower than the sale price per sheet in the previous example. Therefore, the better deal is the 30% discount off the regular price of $18.00, which results in a sale price per sheet of $12.60.
Therefore, the sale price per sheet in this example is $12.60.

describe what we mean by cost, revenue and profit
Answer:
In business and economics, cost, revenue, and profit are key concepts that relate to the financial aspects of a business.
Cost refers to the expenses incurred by a business in order to produce, sell or distribute its products or services. This includes direct costs, such as the cost of raw materials, labor and overhead expenses, as well as indirect costs, such as marketing and administrative expenses.
Revenue, on the other hand, refers to the income generated by a business through the sale of its products or services. Revenue can be calculated by multiplying the price of a product or service by the number of units sold.
Profit is the difference between revenue and cost, and is a measure of how much money a business earns after all of its expenses are paid. A business earns a profit when its revenue exceeds its total costs, including both fixed and variable costs.
Profit can be further broken down into gross profit and net profit. Gross profit is the difference between revenue and the direct cost of producing or delivering a product or service. Net profit, on the other hand, is the profit that remains after all expenses, including indirect costs, taxes and interest payments, have been deducted from revenue.
In summary, cost refers to the expenses incurred by a business, revenue refers to the income generated by the sale of products or services, and profit is the difference between revenue and cost, indicating how much money a business earns after all expenses are paid.

Solve (x-3)^2-2=x+1 graphically
Answer:
Step-by-step explanation:
To solve the equation graphically, we need to first rearrange it into the form of y = f(x). So, let's simplify the given equation:
(x - 3)² - 2 = x + 1
Expanding the left side:
x² - 6x + 9 - 2 = x + 1
Simplifying:
x² - 7x + 6 = 0
Now we can graph the function y = f(x) = x² - 7x + 6 and the line y = x + 1 on the same coordinate axes and find their intersection points.
Here's a graph of the function and the line:
Graph of y=x^2-7x+6 and y=x+1
We can see that the two curves intersect at two points, which have x-coordinates of approximately 1.2 and 5.8. So, the solutions to the equation are x ≈ 1.2 and x ≈ 5.8.
Water flows at 2 feet per second through a pipe with a diameter of 8 inches. A cylindrical tank with a diameter of 15 feet and a height of 6 feet collects the water. What is the height, in inches, of the water in the tank after 5 minutes?
The height of the water in the tank after 5 minutes is approximately 732.6 inches.
What is the equation for a cylinder's volume?V = πr²h, where V is a cylinder's volume, r is its radius, and h is its height, is the formula for calculating a cylinder's volume. The formula is created by first determining the area of the cylinder's base, which equals r2, and then multiplying that area by the cylinder's height to determine the volume. The volume of tanks, pipelines, and other cylindrical objects may be calculated using this formula, among many other uses.
The volume of a cylinder, which is:
V = πr²h
Given that, diameter is 15 feet, so the radius is 7.5 feet.
Also,
2 feet per second = 2 * 12 * 60 inches per minute = 1440 inches per minute
V = πr²h
Substituting the values:
V = π(7.5)^2(14405)
Here, 14405 is the amount of water that flows into the tank in 5 minutes.
Divide the volume of water by the area of the base of the cylinder
V/A = h
2,044,123/(π(7.5)^2) ≈ 732.6 inches
Hence, the height of the water in the tank after 5 minutes is approximately 732.6 inches.

Of all the cookies in a cookie jar, 4/5 are oatmeal of the oatmeal cookies 2/3 have nuts what fraction of all the cookies in the cookie jar are oatmeal with nuts?
By answering the above question, we may state that So, 5333/10000 of linear equationthe cookies in the cookie jar are oatmeal cookies with nuts.
What is a linear equation?In algebra, a linear equation is one that of the form y=mx+b. The slope is B, and the y-intercept is m. As y and x are variables, the previous sentence is frequently referred to as a "linear equation with two variables". Bivariate linear equations are linear equations with two variables. Linear equations may be found in many places, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation has the structure y=mx+b, where m denotes the slope and b the y-intercept, it is referred to as being linear. A mathematical equation is said to be linear if its solution has the form y=mx+b, where m stands for the slope and b for the y-intercept.
For the sake of a simple computation, let's say that the cookie jar contains 100 cookies.
The issue states that 4/5 of the cookies in the jar are oatmeal cookies. So,
80 oatmeal cookies are equal to 4/5 * 100.
Two thirds of the oatmeal cookies have nuts in them. So,
2/3 times 80 equals 53.33 oatmeal cookies with nuts (approx)
As a result, the percentage of cookies in the cookie jar that are made with oats and nuts is:
53.33/100 = 0.5333
This is expressed as a fraction:
0.5333 = 5333/10000
So, 5333/10000 of the cookies in the cookie jar are oatmeal cookies with nuts.

What is 2 times the square root of 48 - the square root of 3 simplified
2 times the square root of 48 minus the square root of 3 simplified is 7√3.
what is square root?
The square root of a number is a value that, when multiplied by itself, gives the original number. In other words, it is the inverse operation of squaring a number. For example, the square root of 16 is 4 because 4 multiplied by itself (4 x 4) equals 16.
The symbol used to represent the square root is √. So, the square root of 16 is written as √16.
To simplify this expression, we can first simplify the square root of 48.
We know that 48 can be written as 16 x 3, and since 16 is a perfect square, we can simplify the square root of 48 as follows:
√48 = √(16 x 3) = √16 x √3 = 4√3
Now we can substitute this value into the expression:
2(4√3) - √3 = 8√3 - √3 = 7√3
Therefore, 2 times the square root of 48 minus the square root of 3 simplified is 7√3.

Element X decays radioactively with a half life of 8 minutes. If there are 470 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 10 grams? y
The decay of Element X can be modeled by the equation:
N = N0 * (1/2)^(t/t1/2)
where N is the amount of Element X remaining after time t, N0 is the initial amount of Element X, t1/2 is the half-life of Element X, and ^(t/t1/2) denotes exponentiation with base 1/2.
We know that the initial amount of Element X is 470 grams, the half-life is 8 minutes, and we want to find the time it takes for Element X to decay to 10 grams. Let t be the time in minutes.
Then, we can set up the following equation:
10 = 470 * (1/2)^(t/8)
Dividing both sides by 470, we get:
(1/47) = (1/2)^(t/8)
Taking the natural logarithm of both sides, we get:
ln(1/47) = (t/8) * ln(1/2)
Solving for t, we get:
t = -8 * ln(47)/ln(2)
t ≈ 59.3
Therefore, it would take about 59.3 minutes, to the nearest tenth of a minute, for Element X to decay to 10 grams.

Mr. Hamstra can travel about 70 miles when his tank is 1/4 full.
How is gas mileage calculated? What is it?The distance a car can go on a given quantity of gasoline is measured as gas mileage, also known as fuel efficiency. By dividing the distance driven by the amount of gasoline used, one may determine gas mileage. For instance, a car's gas mileage is 25 mpg (300/12 = 25) if it can go 300 miles on 12 gallons of petrol. Many variables, including traffic, speed, weather, road gradient, and vehicle maintenance, can have an impact on gas mileage.
Given that, Mr. Hamstra’s car holds 14 2/5 gallons of gas and averages 20 miles per gallon.
Thus, when his tank is 1/4 full, it contains:
1/4 * 14 2/5 = 14 2/5 / 4 = 3 1/2 gallons.

b. The distance between points K and L is 10 units.
c. ΔJKL is not an equilateral triangle.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.
Given points as:
J (-5,-3)
K (1,5),
L (7,-3)
b. To determine the distance between points K and L, we can use the distance formula:
distance = √(x₂ – x₁)² + (y₂ – y₁)²
Substituting the coordinates of K and L, we get:
distance = √((7 - 1)² + (-3 - 5)²)
distance = √(36 + 64)
distance = √(100)
distance = 10
Therefore, the distance between points K and L is 10 units.
c. To determine if JKL is an equilateral triangle, we need to check if all three sides have the same length.
We can find the lengths of each side using the distance formula:
JK = √((1 - (-5))² + (5 - (-3))²) = √(6^2 + 8²) = 10
KL = 10 (as we found in part b)
LJ = √((-5 - 7)² + (-3 - (-3))²) = √((-12)²) = 12
