Yesterday, a movie theater sold 290 bags of popcorn. A large bag of popcorn costs $4. A small bag of popcorn costs $1. In all, the movie theater made $566 from popcorn sales. Write and solve a system of equations to find how many bags of each size of popcorn were sold.
PLEASE HELP
As a result, 198 small bags and 92 big bags of popcorn were sold at the movie theatre.
what is equations ?An equation in mathematics is a claim that two statements are equivalent. It usually has two sections: a left and a right, separated by an equals sign in the middle. For instance, the statement that the expression 2x Plus 3 equals the expression 7 is represented by the equation 2x + 3 = 7. The equation can be used to determine the number of x that causes the equation to hold true when the variable x is unknown. Equations, such as linear equations, quadratic equations, trigonometric equations, and many others, can be used to explain a broad range of mathematical relationships.
given
Let x represent the quantity of big popcorn bags sold and y represent the quantity of small popcorn bags sold.
Based on the knowledge provided, we can create the following system of two equations:
x + y = 290 (the total amount of bags distributed) (the total number of bags sold)
4x + y = 566 (the entire revenue from popcorn sales) (the total revenue from popcorn sales)
We have two options for resolving the equation for x and y: substitution or removal. Here, we'll apply the replacement technique:
Y = 290 - x is the result of solving equation 1. We can enter the following formula in place of y in equation 2:
4x + (290 - x) = 566
If we simplify, we get:
3x + 290 = 566
290 from both parts are subtracted, giving us:
3x = 276
3 divided gives us:
x = 92
Thus, 92 big bags of popcorn were sold. We can change x = 92 into equation 1 to determine how many small packages were sold:
92 + y = 290
92 is subtracted from both parts to arrive at:
y = 198
Thus, 198 small packages of popcorn were sold.
As a result, 198 small bags and 92 big bags of popcorn were sold at the movie theatre.

to
attempt 1 out of 3
Answer:
The equation that can be used to determine the average number of miles Keilantra would have to ride each day to meet her goal is:
(28.8 - 4) / 4 = m
This equation subtracts the 4 miles Keilantra has already ridden from her goal of 28.8 miles, and then divides the result by the number of days she still needs to ride (4) to find the average number of miles she would have to ride each day to meet her goal.
Solving this equation gives: (28.8 - 4) / 4 = m
24.8 / 4 = m
6.2 = m
Therefore, the average number of miles Keilantra would have to ride each day to meet her goal is 6.2 miles.

The length of the rectangle above is 5 inches longer than the width. Which expression could be used to represent the area of the rectangle? help pls (: (quiz)
If we let "x" be the width of the rectangle, then the length would be "x + 5" (since it's 5 inches longer than the width).
The area of a rectangle is given by the formula A = length x width. Substituting in the expressions we found for the length and width, we get:
A = (x + 5)x
Simplifying this expression, we get:
A = x^2 + 5x
Therefore, the expression that could be used to represent the area of the rectangle is "x^2 + 5x".
The area of the shaded region is 277
The length of the radius and diameter are 10.5 and 21 respectively
What is area ?The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units like cm² and m². Area of a shape is a two dimensional quantity.
The area of the sector = tetha/360 × πr²
= 72/360 × 3.14 × r²
= 0.628r²
area of the circle = area of the shaded part + area of sector
3.14r² = 277 + 0.628r²
3.14r²-0.628r² = 277
2.512 r² = 277
r² = 277/2.512
r² = 110.3
r = √ 110.3
r = 10.5
d = 2r
d = 10.5 × 2
= 21

a suitcase with measures 80cm*48cm*24cm is to be covered witha trapulin cloth .how many meters of tarapaulin of width 96cm is reqired to cover 100 such suitcases
To cover one suitcase, we need to find the surface area of the suitcase that needs to be covered. The surface area of the suitcase can be calculated by finding the sum of the areas of its six sides.
Area of one side of the suitcase = length x height = 80cm x 48cm = 3840 sq.cm
Area of the opposite side of the suitcase = length x height = 80cm x 48cm = 3840 sq.cm
Area of the other four sides of the suitcase = width x height = 24cm x 80cm + 24cm x 80cm + 24cm x 48cm + 24cm x 48cm = 7296 sq.cm
Total surface area of one suitcase = 3840 sq.cm + 3840 sq.cm + 7296 sq.cm = 14976 sq.cm
To cover 100 such suitcases, we need to multiply the surface area of one suitcase by 100.
Total surface area of 100 suitcases = 14976 sq.cm x 100 = 1497600 sq.cm
To find the amount of tarapaulin required, we need to divide the total surface area of 100 suitcases by the width of the tarapaulin.
Amount of tarapaulin required = (1497600 sq.cm) / (96 cm) = 15600 sq.cm
We now need to convert the required area into meters.
1 sq.cm = 0.0001 sq.m
15600 sq.cm = 15600 x 0.0001 sq.m = 1.56 sq.m
Therefore, we need 1.56 sq.m of tarapaulin to cover 100 such suitcases, assuming that there is no overlap of the tarapaulin.

The population in this case is all adults in the United States, and the sample is the 1001 adults who were surveyed by Citrix Security.
Is the value of 69% a statistic or a parameter?The sample was selected in such a way as to be representative of the larger population of adults in the United States.
The value of 69% is a statistic, not a parameter. A statistic is a measure that describes a characteristic of a sample, while a parameter is a measure that describes a characteristic of a population. In this case, the 69% refers to the proportion of the 1001 adults surveyed who believe that having their personal information stolen is inevitable, which is a characteristic of the sample. It does not necessarily reflect the proportion of all adults in the United States who hold this belief, which would be a parameter.

What is the volume of the rectangular prism?
To find the volume of a rectangular prism, you need to know its length, width, and height. Let's assume you have those measurements.
The formula for the volume of a rectangular prism is:
volume = length x width x height
We need to know the volume of the classroom in order to determine how many of a certain object it would hold.
The volume of a rectangular prism (like the classroom) is given by the formula:
volume = length x width x height
Plugging in the values we know:
volume = 24 feet x 28 feet x 10 feet
volume = 6720 cubic feet
Now we can divide the volume of the classroom by the volume of the object we want to find out how many will fit.
For example, if we want to know how many basketballs would fit in the classroom, we would need to know the volume of a basketball. According to the NBA, the standard size for a basketball is about 9.43 inches (0.7867 feet) in diameter. The volume of a sphere is given by the formula:
volume = (4/3) x π x radius^3
Plugging in the radius of the basketball:
volume = (4/3) x π x (0.7867/2)^3
volume ≈ 0.193 cubic feet
Dividing the volume of the classroom by the volume of a basketball:
6720 cubic feet / 0.193 cubic feet per basketball ≈ 34,767 basketballs
Hence, the classroom would hold about 34,767 basketballs.

Using the method of solving a system of equations, we grouped each system as no solution, one solution and infinite solutions.
What is a system of equations?
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and visual solutions are possible for these equations. The intersection of two lines represents the system of equations' solution. A group of equations that are all satisfied by the same set of variables are referred to as a system of linear equations. Finding the value of the variable that makes the condition of all the given equations true is the primary goal when solving an equation system.
1) y = -3 and x = -6
This system of equations has only one solution as the variables have only a constant as their value.
2) y = 2x and y = -2x
There is only one solution to this system of equations. It is x =0 and y = 0. This solution only satisfies these equations.
3) y = -x -2
y = -x -6
There is no solution to this system of equations as the mathematical operation on two numbers will not give two values.
4) y = 3x + 4
2y = 6x + 8
There is an infinite number of solutions as the second equation when divided by 2 becomes y = 3x + 4, which is the same as the first equation.
5) y = 9x -1
y = x + 9
There is only one solution for this system of equations.
Therefore using the method of solving a system of equations, we grouped each system as no solution, one solution and infinite solutions.

please show the formula and answer
Answer: The answer should be 35.98 ( or 7π + 14 )
Step-by-step explanation:
The perimeter of a semicircle is half of the circumference plus the diameter. First, we find the circumference, which is (2πr). π * 7 * 2 = 14π. Since we have the circumference, we have to divide it by 2 since it's a semicircle. 14π/2 = 7π. Our next step is to find the diameter. Since the radius of the semicircle is 7, we multiply it by 2. 7 * 2 = 14. Now, let's say that (π = 3.14). So (7 * 3.14) + 14, 21.98 + 14 = 35.98. The answer should be 35.98.

A local publication charges by the number of lines for automotive ads. They charge $34 for the first 4 lines, and $3.50 for each additional line. If x represents the number of lines, express the cost c(x) of an ad as a piecewise function. Graph it and label the slopes as well.
The graph of the piecewise function is added as an attachment
How to determine the piecewise functionLet c(x) be the cost of an automotive ad with x lines.
For the first 4 lines, the cost is $34, so:
c(x) = 34, for 1 ≤ x ≤ 4
For each additional line beyond the first 4, the cost is $3.50, so:
c(x) = 34 + 3.50(x - 4), for x > 4
When these two cases are put together, we get the piecewise function:
c(x) = 34, for 1 ≤ x ≤ 4
c(x) = 34 + $3.50(x - 4), for x > 4
This function represents the cost of an automotive ad as a piecewise function that depends on the number of lines in the ad.

From the given situation of equation Diamond worked 24 overtime hours that week.
What distinguishes regular salary from overtime compensation?The hourly rate that is paid for the typical hours worked within a pay period is known as regular pay. For full-time employees in the US, this is typically referred to as 40 hours a week. On the other hand, overtime pay is the hourly rate paid for any additional hours worked. Most businesses give time-and-a-half (1.5 times the usual pay rate) or double-time (two times the regular pay rate) for extra hours, which is often more than regular compensation.
Let us suppose the number of hours = x.
Let us suppose the overtime hours = y.
From the given situation we have:
7.5x + 11.25y = 352.5 (equation 1)
x + y = 35 (equation 2)
Substituting equation 2 into equation 1 and simplifying:
7.5x + 11.25(35 - x) = 352.5
7.5x + 393.75 - 11.25x = 352.5
-3.75x = -41.25
x = 11

What is Algebraic expression?An Algebraic expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that can be simplified and evaluated.t may contain one or more variables, which are symbols that represent unknown quantities or values that can vary.
Algebraic expressions can be written using letters, symbols, or a combination of both, and they can be used to model real-world situations, solve problems, and express mathematical relationships. For example, "3x + 5" is an algebraic expression that represents a linear equation with one variable "x".
The given expression is d3a2−(c+b), where a = -2, b = 3, c = -12, and d = -4. Substituting these values, we get:
d3a2−(c+b) = (-4)3(-2)² - (-12 + 3) = -434 - (-9) = -48 + 9 = -39
Therefore, d3a2−(c+b) equals -39 when a=-2, b=3, c=-12, and d=-4.

Use two math vocabulary terms and two academic vocabulary terms to describe
the system of equations. Underline each term you use.
y=2x+4
2y-x=8
Answer:
y = 2x + 4 and 2y - x = 8 represent a system of linear equations.
In this system, the variable x represents an unknown value, while the variable y represents a value that can be determined from the equation. The coefficient 2 in the first equation is an example of a math vocabulary term, indicating that the slope of the line is 2. The term "slope" is a mathematical term that describes the steepness of a line.
The term "system" is an academic vocabulary term that refers to a group of related equations or inequalities. In this case, we have a system of two linear equations that are related to each other.
The second math vocabulary term is "solution", which refers to the set of values of the variables that satisfies both equations in the system. In this case, the solution is the unique point (3, 10), where x = 3 and y = 10.
Finally, the academic vocabulary term "consistent" is used to describe a system of equations that has at least one solution. In this case, the system is consistent because it has exactly one solution, which means the two equations intersect at a single point.
