The profit for hundred cell phone is $65000
The cost of a cell phone is $2500
and sold for $3150
The selling price of a cell phone is $3150 and
The cost price of a cell phone is $2500.
What is Profit and Loss in mathematical term?To ascertain a commodity's market price and assess a business's profitability, mathematicians utilize the profit and loss formula. The cost price and the selling price of every thing are different. We are able to determine a product's profit or loss based on the values of these prices.
Step-by-step explanation:
Profit = Selling price - Cost price
Profit = $3150 - $2500
Profit = $650
The profit for one cell phone is $650
We have to find the profit for hundred cell phone
$650 × 100 = $65000
The profit for hundred cell phone is $65000.

A teacher asks students to place tiles on the classroom wall to show the alphabet. The tiles will each have one letter or be blank. Each letter will have only one tile. The list shows the teachers rules for the arrangement of tiles.
• How many columns of tiles will there be?
• How many blank tiles will be used?
• What multiplication fact helped you solve the problem?
1. They must form a rectangle.
2. The rectangle must have 4 rows.
3. The rectangle must have the least possible number of columns.
The least possible number of columns is 7
2 blank tiles is will be used
Yes using multiplication facts the question can be solved.
Given data
Alphabet arrangement on tiles
The rules for arrangement of the alphabets
1. They must form a rectangle.
2. The rectangle must have 4 rows.
3. The rectangle must have the least possible number of columns.
How to find the column of tiles the arrangement will havenumber of alphabets = 26
let the row represent the width of the rectangle, so that the rectangle has 4 rows.
The length will be
length * width = 26
length = 26 / width
length = 26 / 4
length = 6.5 ≅ 7
Hence the least possible number of columns is 7
How to find the number of blank tiles used
26 / 4 gives 6 remainder 2 hence it requires 2 more tiles to make it up a rectangle of 7 columns.
The remaining part is filled with blank tiles therefore 2 blank tiles is used
How to solve the problem with multiplication factUsing multiplication we solve the problem as thus:
let the number of column be x such that
4 * x = 26
x = 26 / 4
so we use blank tiles to make the equation divisible by 4 without remainder.
using mental math: 28 / 4 = 7
therefore 2 blank tiles were added and the minimum number if rows is 7
Yes using multiplication facts the question can be solved.

Which expression is equivalent to (2x − 1)(4x + 3) − (9x + 1)(2x − 1)?
The given expression (2x − 1)(4x + 3) − (9x + 1)(2x − 1) is equivalent to -10x^2 + 9x - 2, that is, option b.
If terms of the form (a + b) and (a + c) are to be multiplied, then each number or variable in the 1st term is multiplied by every variable in the 2nd term. Thus, (a + b)(a + c) = a^2 + ac + ab + bc.
Here, we are given an expression (2x − 1)(4x + 3) − (9x + 1)(2x − 1)
let us simplify the given expression-
[2x(4x) + 3(2x) -4x - 3] - [9x(2x) -9x + 2x -1)]
8x^2 + 6x - 4x - 3 - (18x^2 -9x + 2x -1)
8x^2 + 2x - 3 - 18x^2 +7x +1
8x^2 -18x^2 + 2x +7x -3 +1
-10x^2 + 9x - 2

A 3-by-3 magic square :

A square array of numbers, often positive integers, is referred to as a magic square in recreational mathematics if the sums of the numbers in each row, each column, and both main diagonals are the same.
The following values are listed in the question:
The numbers are 4, 5, 6, 14, 15, 16, 24, 25, and 26.
A 3-by-3 magic square is required.
Since the numbers are 4, 5, 6, 14, 15, 16, 24, 25, and 26.
Now the sum of all numbers is :
4 + 5 + 6 + 14 + 15 + 16 + 24 + 25 + 26 = 135
There are now 3 rows and 3 columns, thus the total number is divided by 3.
5 24 16
26 15 4
14 6 25
5 + 24 + 16 = 45
5 + 26 + 14 = 45
26 + 15 + 4 = 45
24 + 15 + 16 = 45
14 + 6 + 25 = 45
5 + 15 + 25 = 45
So, the total of each row and each column is therefore 45.
Therefore, this is a 3-by-3 magic square that satisfies the conditions :

Find The Slope of the Line?
Answer: 3
Step-by-step explanation:
To find the slope you have to divide y over x: y/x or most commonly known as rise/run.
We start at the point where the line is touching a point, in this case it's -8 in the y axis.
Then we count up until we find another point that the blue line is touching. In this case at the coordinates (2, -2). So there's 6 values up from -8 and we have to move to the right 2 values to reach the point the blue line is touching.
So we use the formula rise/run or y/x:
6/2 = 3

Create a description in words for the table.
The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.
The number of calories burned is dependent on the number of hours working out. For every 240-hour workout, there is 1 calorie burned, and for every 480-hour workout, there are 2 calories burned.
The number of hours working out is dependent on the number of calories burned. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.
The number of hours working out is dependent on the number of calories burned. For every 240-hour workout, there is 1 calorie burned, and for every 480-hour workout, there are 2 calories burned.
Answer: The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.
Step-by-step explanation:
By observing the nature of the question, we can decide that the amount of time spent working out dictates the number of calories we burn, making the workout (hours) the independent variable and the calories burned the dependent. This automatically cancels out the answers C and D.
We then just use our knowledge of the table. The hours were assigned 1, 2, and 3, and the calories were 240, 480, and 720. Just make sure the answer reflects that! That gives us answer choice B, The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.

So, For this purpose, we know that the
Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
From the given information:
After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6, 3), B'(-2, 1),and C(1, 7).
Then
We need to search out the coordinates of the pre-image A, B and C.
The rule for rotation of 90° about the origin is (x,y) ---> (-y,x).
But we want to seek out the coordinates of the vertices of the pre-image.
So, we'd like to use rule (-y,x) ---->(x,y).
Applying rule,
A'(6, 3) -----> A (3, -6)
B'(–2, 1) -----> B(1, 2)
C'(1,7) -----> C (7, -1).

Line (1): 8x4 = 2(4x + 1) -6
Line (2): 8x - 4 = 8x +1-6
Line (3): 8x - 4 = 8x - 5
Line (4): -4 = -5
Line (5): Based on the calculations above, there are no solutions.
O The error occurred from line (1) to line (2).
The error occurred from line (2) to line (3).
The error occurred from line (3) to line (4).
O The error is in line (5).
The error occurred from line (2) to line (3) i.e., option(b) is correct.
Given that, Line (1): 8x-4 = 2(4x+1)-6, so we will procced to solve line (1) accordingly and then with the steps we will find where the error exactly occur. Let's proceed to solve this question.
8x-4 = 2(4x+1)-6
Now, open or simplify the bracket in RHS, we get
8x-4 = 8x+2-6
Now, simplify RHS accordingly, we get
8x-4 = 8x-4
Now add 4 both sides, we get
8x-4+4 = 8x-4+4
8x = 8x
Now, divide both sides by 8, we get
x = x
Now, subtract x from both sides, we get
0 = 0
Both sides are equal.
⇒ True for all x.
So, from the above calculation steps we can easily concluded that the error occurred from line (2) to line (3).
Hence, option(b) is correct.

Solving a linear equation, we will see that 109 attendees did not visit the concession stand.
How to find the number of attendees who did not visit the concession stand?
First, we know that the total number of surveyed people is 680.
Of these 680, we know that:
527 said that the concession stand prices are excessive.44 said that the concession stand prices are not excessive.x did not visit the concession stand.Now, the 3 numbers above should add up to the total number of surveyed people.
527 + 44 + x = 680
Solving that linear equation for x:
x = 680 - 527 - 44 = 109
We conclude that the number of attendees who did not visit the concession stand is 109.
