Answer: PROFIT= 15
PROFIT PERCENT(%)=5%
Step-by-step explanation: As the article is bought at 300 and sold at 315, the difference between the buying and the selling prices is the profit.
Profit is the margin between the price you have bought and the price at which you have sold.
That is 315-300= 15
Now the percentage 15/300*100 = 5
To know the percentage, we have to divide the given value by the total value and after that multiply the result by 100.
Here the given value which is profit is 15 and the total is 300
After dividing 15/300 We get 0.05 and multiply by 100= 5.
So the percentage is 5%.

Answer: The profit is Rs 15 and the profit per cent is 5%.
Step-by-step explanation:
Purchase Price: Rs 300
Selling Price: Rs 315
profit: 315-300=15 ( profit=selling price -cost price)
profit percentage= (15/300)*100 ( profit percentage= (profit/cost price)*100)
What’s the force on an object with a mass of 10 kg and an acceleration of 4 m/s
The force on the object is 40N
What is force?Force can be described as the influence that can change the motion of an object.
It is seen as an external agent having the capability of changing a body's state of motion or rest.
It causes b in velocity of an object with mass , that is, to accelerate. Force can also be described as either a push or a pull.
It is described as a vector quantity, that is, it has both magnitude and direction.
The formula for determining force is given as;
F = ma

Use arrow notation to describe the translation of point P(–10, 1) to point P′(–16, –1).
Answer: In order to describe a translation using arrow notation, we need to specify the direction and distance of the translation. In the case of the given translation, point P is translated to point P' by moving 6 units to the left and 2 units down. This can be represented using arrow notation as follows:
P' = P ← 6 ↓ 2
Here, the symbol ← represents a leftward movement, and the symbol ↓ represents a downward movement. The numbers 6 and 2 indicate the distance of the movement in the respective directions. This means that point P is translated to point P' by moving 6 units to the left and 2 units down from its original position.

Hailey goes to a restaurant and the subtotal on the bill was xx dollars. A tax of 8% is applied to the bill. Hailey decides to leave a tip of 24% on the entire bill (including the tax). Write an expression in terms of xx that represents the total amount that Hailey paid.
The expression in terms of xx that represents the total amount that Hailey paid is (2912/625)xx .
What is business Mathematics?
Business mathematics is the branch of mathematics utilized by businesses to track and coordinate their operations. Accounting, inventory management, marketing, sales forecasting, and financial analysis are all areas where commercial businesses apply mathematics.
According to Question:
let the the subtotal on the bill was xx dollars
A tax of 8% is added on bill then Bill becomes xx + 8% of xx
The of 8% on bill = (108/100)xx
Now the Final bill = xx + (108/100)xx
= (208/100)xx
Hailey decides to leave a tip of 24% on the entire bill (including the tax)
So the Total Amount = (208/100)xx + 24% of Final bills
⇒
24% of (208/100)xx = (208/100)(124/100)xx
The Total amount = (208/100)xx +(208/100)(124/100)xx
Let the Amount be A
hence, expression in terms of xx that represents the total amount that Hailey paid is A = (208/100)xx +(208/100)(124/100)xx
⇒ A = (52/25)xx +(52/25)(31/25)xx
⇒ 625A = 625((52/25)xx +(52/25)(31/25)xx)
⇒ 625A = 1300xx + 1612xx
⇒ 625A = 2912xx
⇒ A = (2912/625)xx

(a) u
The approximate mean and standard deviation of the number of chips meeting specifications are: μ = 16.2; σ = 1.273
In this question, we have been given a factory makes silicon chips for use in computers. it is known that about 90% of the chips meet specifications. every hour a sample of 18 chips is selected at random for testing and the number of chips that meet specifications is recorded.
we need to find the approximate mean and standard deviation of the number of chips meeting specifications
Since 90% meet specifications we can say p = 0.9
So, q = 1 - p
q = 1 - 0.9
q = 0.1
here, a sample size is n = 18
So, the mean would be,
μ = np
μ = 18 * 0.9
μ = 16.2
And the standard deviation would be,
σ = √npq
σ = √(18 * 0.9 * 0.1)
σ = 1.273
Therefore, the mean (μ) = 16.2 and the standard deviation (σ) = 1.273

Let’s simplify this equation:
25x + 5 =26x

O5, 12, 13
The lengths of the sides of the triangle are 5, 12, and 13.
So the correct option is the last one.
How to find the lengths of the sides?Remember that if we have two points (x₁, y₁) and (x₂, y₂), the distance between these two points is given by the formula:
d = √( (x₁ - x₂)² + (y₁ - y₂)²)
Here we know that the vertices of our triangle are the points:
(0, 0), (5, 0), (5, 12)
And we want to find the lengths of the sides.
We can get the length of the first side using the points (0, 0), (5, 0)
d₁ = √( (0 - 5)² + (0 - 0)²) = 5
The length of the second side is: (5, 0), (5, 12).
d₂ = √( (5 - 5)² + (0 - 12)²) = 12
The length of the third is side is given by the points (5, 12) and (0, 0)
d₃ = √( (5 - 0)² + (12 - 12)²)
d₃ = √(25 + 144) = 13

What is an isosceles triangular prism?The faces of a polyhedron called an isosceles triangular prism are made up of polygons. It has six edges, five faces, and five vertices. Isosceles triangles make up the two portions at the base that face each other and rectangles make up the vertical faces of the five faces.
where the isosceles triangle's base has equal sides measured in "a" units, each triangle's base measured in "b" units, the triangle's height measured in "h" units, and the length of the congruent rectangles measured in "l" units.
The surface area of an isosceles triangular prism is:
Surface area = (b × h) + (2× l × a) + (l × b)
here, b = the base of each of the triangle = 16 feet
h = the height of the triangle = 18 feet
l = length of the congruent rectangles = 10 feet
