Sam needs a new crate for his puppy, Barney. The old crate, which is shaped like a rectangular prism, is 16 inches long, 9 inches wide, and 10 inches tall. Barney's new crate is also shaped like a rectangular prism, but it is 24 inches long, 10 inches wide, and 12 inches tall.
How many cubic inches larger is Barney's new crate than his old crate?
Barney's new crate is 1,440 cubic inches larger than his old crate.
The volume of the old crate is:
16 inches x 9 inches x 10 inches = 1440 cubic inches
The volume of the new crate is:
24 inches x 10 inches x 12 inches = 2880 cubic inches
To find how many cubic inches larger the new crate is than the old one, we can subtract the volume of the old crate from the volume of the new crate:
2880 cubic inches - 1440 cubic inches = 1440 cubic inches
Therefore, Barney's new crate is 1440 cubic inches larger than his old crate.

Select all of the expressions that are equal to 6 × 45.
A. 6 × (40 + 5)
B. 4 + 2 × 45
C. (6 × 40) + (6 × 5)
D. (6 + 40) × (6 + 5)
E. 6 × (20 + 25)
Answer:
A and C.
Step-by-step explanation:
Because 6x45=270. And if you look at the problem, 6x(40+5). Of course, you do the parentheses first. So 40+5= 45. Then 6x45. And once again, you get 270. Then for C, 6x40= 240. And, 6x5= 30. Then, add. 240+30= 270.
Other things being equal, larger automobile engines are less fuel efficient. You are planning an experiment to study the effect of engine size (in liters) on the fuel efficiency (in mpg) of sport utility vehicles. In this study
a. gas mileage is a response variable, and you expect to find a negative association.
b .gas mileage is a response variable, and you expect to find a positive association.
c. gas mileage is an explanatory variable, and you expect to find a strong negative association.
d. gas mileage is an explanatory variable, and you expect to find a strong positive association.
e. gas mileage is an explanatory variable, and you expect to find very little association.
The correct answer is (a) gas mileage is a response variable, and you expect to find a negative association.
The reason for this is that other things being equal, larger automobile engines require more fuel to operate, which means they are less fuel efficient. Therefore, as engine size (in liters) increases, we would expect fuel efficiency (in mpg) to decrease.
To test this hypothesis, we would need to gather data on the engine size and fuel efficiency of a sample of sport utility vehicles. We could then use regression analysis to determine the strength and direction of the association between engine size and fuel efficiency. If our hypothesis is correct, we would expect to see a negative coefficient for engine size in our regression model, indicating that larger engine sizes are indeed associated with lower fuel efficiency.
In summary, when studying the effect of engine size on fuel efficiency, gas mileage is the response variable and we expect to find a negative association between engine size and fuel efficiency.

in an assignment problem, each resource can perform how many tasks?
In an assignment problem, each resource can perform only one task. The assignment problem is a linear programming problem that seeks to minimize the cost of assigning tasks to available resources.
An assignment problem is a combinatorial optimization problem in which a group of jobs must be assigned to a group of workers while minimizing the total cost of completing the jobs. This type of problem is solved using linear programming. In addition, there is a one-to-one matching between the set of jobs and the set of workers. The goal of an assignment problem is to find the optimal or best possible pairing of jobs to workers.To obtain the best possible solution, an optimal assignment algorithm can be utilized. There are four basic methods to solve the assignment problem: the Hungarian method, the matrix reduction method, the branch-and-bound method, and the Auction algorithm.

6. Suppose that f(n) = 2f (n/2) + 3 when n is an even positive integer, and f(1) = 5. (a) Find f(16). (b) Give a big-O estimate for the function f.
To find f(16), we can use the given recursive formula. Since 16 is an even number, we apply the formula:
f(16) = 2 * f(16/2) + 3 = 2 * f(8) + 3.
Next, we apply the formula again with 8 as an even number:
f(8) = 2 * f(8/2) + 3 = 2 * f(4) + 3.
Repeating the process with 4:
f(4) = 2 * f(4/2) + 3 = 2 * f(2) + 3.
Finally, applying the formula with 2:
f(2) = 2 * f(2/2) + 3 = 2 * f(1) + 3 = 2 * 5 + 3 = 13.
Therefore, f(16) = 13.
To estimate the function f with big-O notation, we observe that each step in the recursion doubles the input size while adding a constant term of 3. Hence, we can say that f(n) is O(log n) since it grows logarithmically with respect to n.

Karia gave each of her 8 friends an equal number of flyers to pass out at the upcoming student government vote. She also gave each of them person 2 bags to carry their flyers. Karia had 200 items to hand out to students including the bags. Write an equation to represent this situation
PLEASE HELP!!! 10 POINTS!!
Answer:
8x + 8 * 2 = 200
Step-by-step explanation:
Let's assume that each friend received x flyers to pass out.
The equation would be:
8x + 8 * 2 = 200
8x = 184
x = 23
So each friend received 23 flyers and 2 bags, and in total, they received 23 * 8 + 8 * 2 = 200 items.
Write an equation of the graph shown in terms of cosine:
Answer:
Step-by-step explanation:
A squiggly line can refer to a variety of different shapes or patterns. To create an equation using cosine that resembles a squiggly line, you can use a combination of sine and cosine functions with different frequencies and amplitudes. Here's an example equation that produces a squiggly pattern:
y = A * cos(B * x) + C * sin(D * x)
In this equation, A, B, C, and D are constants that you can adjust to modify the shape and characteristics of the squiggly line. By experimenting with different values for these constants, you can create various squiggly patterns. Keep in mind that the specific equation may vary depending on the exact shape and features you have in mind for the squiggly line.
Surveying Property A surveyor locating the corners of a triangular piece of property started at one corner and walked 480 ft in the direction of N36°W to reach the next corner. The surveyor turned and walked S21°W to get to the next corner of the property. Finally, the surveyor walked in the direction N82°E to get back to the starting point. What is the area of the property in square feet?
The area of the triangular piece of property is approximately 63,121.75 square feet.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Starting at the first corner, the surveyor walks 480 ft in the direction N36°W. We can break this down into its northward and westward components:
Northward component = 480 cos(36°)
≈ 388.75 ft
Westward component = 480 sin(36°)
≈ 295.42 ft
This takes the surveyor to the second corner of the property.
From the second corner, the surveyor walks S21°W to get to the third corner. We can again break this down into its southward and westward components:
Southward component = 480 cos(21°)
≈ 435.89 ft
Westward component = 480 sin(21°)
≈ 168.75 ft
Finally, the surveyor walks N82°E to get back to the starting point.
We can break this down into its northward and eastward components:
Northward component = 388.75 ft
Eastward component = 435.89 sin(82°)
≈ 426.04 ft
Now we have the lengths of all three sides of the triangular property:
Side 1 = 480 ft
Side 2 = √[(295.42 - (-168.75))^2 + (388.75 - 435.89)^2]
≈ 421.66 ft
Side 3 = √[(426.04 - 295.42)^2 + (388.75 - 0)^2]
≈ 296.13 ft
calculate the area of the triangular property, we can use Heron's formula:
Area = √[s(s - a)(s - b)(s - c)]
where s is the semiperimeter (half the perimeter) of the triangle,
and a, b, and c are the lengths of its sides.
s = (480 + 421.66 + 296.13)/2 ≈ 598.40
Area = √[598.40(598.40 - 480)(598.40 - 421.66)(598.40 - 296.13)]
Area ≈ 63,121.75 sq ft
Therefore, the area of the triangular piece of property is approximately 63,121.75 square feet.

the fetus experiences tactile stimulation in the womb as a result of
The fetus experiences tactile stimulation in the womb as a result of: several factors including movement, pressure, and the mother's digestive and respiratory systems.
What is tactile stimulation?Tactile stimulation is the sense of touch. The fetus can experience a sense of touch even while still in the womb. The sense of touch can be evoked by several factors including movement, pressure, and the mother's digestive and respiratory systems.In the womb, the fetus is in a dark, warm, and quiet environment.
Therefore, they can feel when their mother touches her stomach or when someone touches her from outside the belly. The tactile stimulation also occurs when the fetus moves around or kicks and stretches. The fetus' tactile sensitivity has been shown to be well-developed by the end of the first trimester.
The fetus is also sensitive to pressure changes. This is because the amniotic fluid in which they are suspended is influenced by changes in pressure. For instance, if the mother is sitting, standing, or lying down, this causes changes in the pressure of the amniotic fluid.
These changes cause the fetus to move or shift their position. This movement, in turn, stimulates the fetus' tactile senses.
