Using the division method it is obtained that Moses is left with 2 dog treats after feeding the 4 dogs with 3 dog treats each.
What is division?
One of the four fundamental mathematical operations—the others being addition, subtraction, and multiplication—is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.
Number of dogs Moses volunteers with, x = 4
Number of dog treats Moses have, y = 14
Number of dog treats Moses gives to each dog = a
So, to find the value for a use the division method -
a = y/x
a = 14/4
a = 3(2/4)
Where, 3 is the quotient and 2 is the remainder.
Therefore, Moses gives each dog 3 treat and have 2 treats left.

Percentage = (present quantity/whole quantity)×100
Given that,
Mike asked 200 students to select their favorite sport and then recorded the results in the bar graph
the percentage of students who selects football is,
Percentage = (50/200)×100
Percentage = 25%
If we consider in same percentage students will select football in next 140 students,

A bag and a ign pen cot 153. 75 peo. The bag cot 28. 85 peo more than the ign pen. How much doe each cot?
As per the unitary method, the cost of bag is $93.3 and the cost of pen is $64.45
The term unitary method in math is known as the process of solving the the value of a single unit, and based on this value we can find the value of the required number of units.
Here we have given that the cost of pen and bag is $153.75.
Here we also know that the bag cost $28.85 more than the pen.
Let us consider that x be the cost of pen and here we know that the cost of bag is $28.85 more than the pen then it can be written as,
=> x + 28.85
Therefore, the equation is written as,
=> x + (x + 28.85) = 153.75
Now, we simplify the equation, then we get,
=> 2x + 28.85 = 153.75
Here we need to find the value of x, so, we have to move the other terms on the other side, then we get
=> 2x = 153.75 - 28.85
=> 2x = 124.9
Therefore, the value of x is 64.45.
Therefore, the cost of bag is calculated as,
=> x + 28.85
=> 64.45 + 28.85
=> 93.3

What does math division mean?Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.
Any number must have a divisor that is less than the dividend when we divide it. Every time, deduct the product from the dividend number before moving on to the next number in the sequence. Always write the product below the dividend number and the quotient above the line.

Which function has a vertex on the y-axis?
f(x) = (x – 2)2
f(x) = x(x + 2)
f(x) = (x – 2)(x + 2)
f(x) = (x + 1)(x – 2)
The function whose vertex is on the y-axis is f(x) = (x – 2)(x + 2).
Option C is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Write each of the functions in the form of ax² + bx + c
Vertex of the function.
= ( -b/2a, f(-b/2a) )
Now,
f(x) = (x – 2)²
x² - 2x + 4
a = 1, b = -2, c = 4
-b/2a = 2/2 = 1
f(1) = -2
Vertex = (1, -2)
f(x) = x(x + 2)
x² + 2x
a = 1, b = 2, c = 0
-b/2a = -2/2 = -1
f(-1) = -1(-1 + 2) = -1
Vertext = (-1, -1)
f(x) = (x – 2)(x + 2)
x² + 2x - 2x + 4
x² + 4
a = 1, b = 0, c = 4
-b/2a = 0
f(0) = (0 -2)(0 + 2) = -4
Vertex = (0, -4)
f(x) = (x + 1)(x – 2)
x² - 2x + x - 2
x² - x + 2
a = 1, b = -1, c = 2
-b/2a = 1/2
f(1/2) = (1/2 + 1)(1/2 - 2) = 3/2 x -3/2 = -9/4

What exactly is a complex number?Complex numbers are defined as a combination of real and fictitious numbers. Z = a + ib, where a and bi are real and imaginary numbers, is how a complex number is expressed.Let z = 19 + i and w = 4 + 10i.
Making a decision is the first step.
The steps to find the product of complex numbers z and w are as follows.
z. w = ( 19 + i )( 4 + 10i ).
applying distributive law,z. w = 19 * (4 10i) i * (4 10i).

The function f(x) = -0.5x^2 + 32.5x - 375 gives a company's profit (or loss) in thousands of dollars, based on what it charges for it's product, x in dollars. If the product is too cheap, the company will not make enough money. If it is too expensive, it will not sell well. A company "breaks even" when it makes enough money to cover it's costs, but hasn't yet made a profit. To break even or make money, how much should the company charge for it's product.
To break even or make money, the company should charge at least $_______ for it's product but no more than $_______
To break even or make money, the company should charge at least $15 for it's product but no more than $50.
How to find the solution to quadratic functions?We are given the function that shows the company's profit or loss as;
f(x) = -0.5x² + 32.5x - 375
This function represents a company's profit (or loss) in thousands of dollars.
x represents what it charges for it's product, x in dollars.
Thus, for it to break even, we have to equate f(x) to zero and solve for x to know the maximum and minimum values of x.
Using quadratic formula, we have;
x = [-b ± √(b² - 4ac)]/2a
x = [-32.5 ± √(32.5² - 4(-0.5 * -375))]/2(-0.5)
x = 15 or 50
Thus, the break even charge has a minimum of $15 and a maximum of $50

What is 2 with an exponent of 7?
2 with an exponent of 7 is 128. It means 2 multiplied by itself 7 times.
When a number is raised to a certain power, it means that the number is multiplied by itself that many times. For example, 2 with an exponent of 7 means 2 multiplied by itself 7 times.
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128So, 2 with an exponent of 7 is 128.
It's important to note that the exponent is also known as the power, so 2^7 is also read as 2 to the power of 7.

Here,
Given :
∵ The inequality is -3(2x - 5) < 5(2 - x)
At first simplify each side
∵ -3(2x - 5) = -3(2x) + -3(-5)
Remember (-)(-) = (+)
∴ -3(2x - 5) = - 6x + 15
∵ 5(2 - x) = 5(2) + 5(-x)
Remember (+)(-) = (-)
∴ 5(2 - x) = 10 - 5x
∴ - 6x + 15 < 10 - 5x
Subtract 15 from both sides
∴ - 6x < -5 - 5x

Place Logan's house at 2 on the number line.
To go from -3 to 2, move 5 units to the right. This is the longest distance possible because each person's house is on opposite sides of the baseball park.
To get the shortest distance possible, we'll place each person's house to the right of 0. This time each person's house is on the same side.

A) They can.
B) They can't.
C) They can.
Is it possible to buy 250 rolls of wrapping paper?
First, we know that:
A roll of wrapping paper cost $2A roll of ribbon cost $3And we know that the math club must spend less than $600.
The cost of 250 rolls of wrapping paper will be:
cost = 250*$2 = $500
This is smaller than $600, so they can buy the 250 rolls of wrapping paper.
B) 250 rolls of ribbon will cost:
cost = 250*$3 = $750
This is more than the amount that they have to spend, then they can't buy 250 rolls of ribbon.
C) Here we have the case of 100 of each, the total cost will be:
cost = 100*$2 + 100*$3
cost = $200 + $300 = $500
This is less than their budget, so they can buy this.
More generally, if x = number of rolls of wrapping paper and y = number of rolls of ribbon, we can write the inequality:
