it will take approximately 1.30 loads of trash from the garbage truck to fill the 40-foot by 9-foot by an 8-foot storage container. However, since you can't have a partial load, you would need to round up to 2 loads to completely fill the container.

what is an 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.

To determine the number of loads of trash from the garbage truck that will fill a 40-foot by 9-foot by 8-foot storage container, we need to compare the volume of the container to the volume of the garbage truck's back.

The volume of the garbage truck's back is:

V_garbage_truck = length x width x height

V_garbage_truck = 23 ft x 8 ft x 12 ft

V_garbage_truck = 2,208 cubic feet

The volume of the storage container is:

V_container = length x width x height

V_container = 40 ft x 9 ft x 8 ft

V_container = 2,880 cubic feet

To find out how many loads of trash from the garbage truck will fill the storage container, we need to divide the volume of the container by the volume of the garbage truck's back:

Number of loads = V_container / V_garbage_truck

Number of loads = 2,880 cubic feet / 2,208 cubic feet

Number of loads ≈ 1.30 loads

Therefore, it will take approximately 1.30 loads of trash from the garbage truck to fill the 40-foot by 9-foot by an 8-foot storage container. However, since you can't have a partial load, you would need to round up to 2 loads to completely fill the container.

What is the quadratic equation?

The quadratic equation is a mathematical formula used to find the solutions (roots) of a quadratic function, which is a second-degree polynomial function of the form:

ax^2 + bx + c = 0

To solve for x in the equation x² + 6x + 9 = 12, we can start by simplifying the left-hand side by factoring the quadratic expression:

(x + 3)² = 12

Taking the square root of both sides, we get:

x + 3 = ±√12

Simplifying the right-hand side, we get:

x + 3 = ±2√3

Finally, solving for x, we have:

x = -3 ± 2√3

Therefore, the solution for x is:

x = -3 + 2√3 or x = -3 - 2√3

So, the correct response is:

x=−3±2√3

Hence, the correct answer would be x equals negative 3 plus or minus 2 root 3

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.

Step-by-step explanation:

By answering the above question, we may state that As a result, there is standard deviation a roughly 0.9999 or 99.99% chance that the sample mean will be within 8 of the population mean.

A statistic known as standard deviation may be used to indicate the variation or variability of a set of statistics. A low standard deviation means that the values tend to be closer to the established mean whereas a large standard deviation shows that the values are widely spread. The standard deviation serves as a gauge for how far the data are from the mean (or ). The data tend to cluster around the mean when the standard deviation is low, and are more scattered when the standard deviation is high. Standard deviation is a measurement of the data set's average variability. It displays the standard deviation of each score with respect to the mean.

population + standard deviation departure from the mean / sqrt (sample size)

Standard deviation is 90/sqrt(100) and equals 9.

z is equal to (x - ) / ( / sqrt(n)).

where:

The sample mean is x. We are looking for the probability given the following conditions: where is the sample size, which is 100; is the population mean, which is 400; is the standard deviation of the distribution of sample means, which is 9;

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.

Step-by-step explanation:

The dimensions of the window that maximize the area of the window is x = 17/(π - 1)(2) and y = 17 - (17/(π - 1)(2)) (1 + π ).

An area is just a surface that is empty. The length and breadth of a form are used to compute its area. The units used to measure length are unidimensional and include feet (ft), yards (yd), inches (in), etc. Nevertheless, a shape's area can only be measured in two dimensions. As a result, it is expressed in square units such as square inches (in2), square feet (ft 2), square yards (yd2), etc. Most forms and things have edges and corners. When determining an object's area, the length and breadth of these edges are taken into account.

Let us suppose the width of the rectangle = x.

The length of the rectangle = y

Thus,

Perimeter = 2 (x + y) + πx

34 = 2x + 2y + πx

2y = 34 - 2x + πx

The area of the window is:

A = (1/2)πx²+ xy

Substitute y = 34 - 2x + πx / 2

To maximize the area we differentiate the area and equate it to 0:

A = (1/2)πx²+ x(34 - 2x + πx / 2)

A =  (1/2)πx²+ 17x - x² + π/2x²

dA/dx = πx + 17 - 2x + πx

2πx + 17 - 2x = 0

2x(π - 1) = - 17

x = 17/(π - 1)(2)

Substitute the value of x in equation:

2y = 34 - 2x + πx

2y = 34 - 2(17/(π - 1)(2)) + π( 17/(π - 1)(2))

y = 17 - (17/(π - 1)(2)) (1 + π )

Hence, the dimensions of the window that maximize the area of the window is x = 17/(π - 1)(2) and y = 17 - (17/(π - 1)(2)) (1 + π ).

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.

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.
