To determine the volume of each congruent square pyramid when three of them are assembled into a cube with a side length of 2 feet, we need to divide the volume of the cube by 3.

The volume of each pyramid can be calculated based on the formula for the volume of a pyramid, considering the dimensions of the cube. The volume of a cube can be found by cubing the length of its side. In this case, the cube has a side length of 2 feet, so its volume is (2 ft)^3 = 8 cubic feet.

Since three congruent square pyramids make up the cube, we can divide the volume of the cube by 3 to find the volume of each pyramid. Therefore, the volume of each pyramid is 8 cubic feet / 3 = 2.67 cubic feet. This means that each individual pyramid, when combined with two others, would occupy a volume of approximately 2.67 cubic feet within the cube.

Based on the given conditions, Jane has $31, Kevin has $25, and Hans has $50 in their wallets.

Let's solve the problem step by step.

First, let's assume that Jane has X dollars in her wallet. Since Kevin has $6 less than Jane, Kevin would have X - $6 dollars in his wallet.

Next, we're given that Hans has 2 times what Kevin has. So, Hans would have 2 * (X - $6) dollars in his wallet.

According to the information given, the total amount of money they have in their wallets is $106. We can write this as an equation:

X + (X - $6) + 2 * (X - $6) = $106

Simplifying the equation:

4X - $18 = $106

4X = $124

X = $31

Now we know that Jane has $31 in her wallet.

Substituting this value into the previous calculations, we find that Kevin has $31 - $6 = $25 and Hans has 2 * ($25) = $50.

To find the total amount they have, we sum up their individual amounts:

Jane: $31

Kevin: $25

Hans: $50

Adding these amounts together, we get $31 + $25 + $50 = $106, which matches the total amount stated in the problem.

The ratio of change in the area of a rectangle, given that the length has increased in the ratio 3:2 and the width has reduced in the ratio 4:5 and the ratio of change in the area of the rectangle is 1.2, indicating a 20% increase in the area from the original size.

Let's calculate the new length and width of the rectangle. The original length is 18 cm, and it has increased in the ratio 3:2. So, the new length can be calculated as (18 cm) * (3/2) = 27 cm. Similarly, the original width is 15 cm, and it has reduced in the ratio 4:5. Hence, the new width can be calculated as (15 cm) * (4/5) = 12 cm.

The original area of the rectangle is (18 cm) * (15 cm) = 270 cm². The new area is (27 cm) * (12 cm) = 324 cm². Therefore, the ratio of change in the area can be calculated as (324 cm²) / (270 cm²) = 1.2.

Hence, the ratio of change in the area of the rectangle is 1.2, indicating a 20% increase in the area from the original size.

Answer:

area = 132 m²

perimeter = 62 m

Step-by-step explanation:

The easiest way to calculate the area of the shape is to work out the area of the entire rectangle, then subtract the area of the 2 small (white) square:

Area of a rectangle = width x length

⇒ area = 10 x 15 = 150 m²

Area of one square = 3 x 3 = 9

Total area = 150 - 9 - 9 = 132 m²

Perimeter = (2 x 10) + 15 + (9 x 3) = 62 m

We start off by drawing out the triangle on a graph! Placing points (x ,y) at

(-3, 5), (-5, -2) and (2, -2). I've included a screenshot of how the triangle should look to help you out visually!

From there, to find the area we use the equation, area = \(\frac{1}{2}\) b • h.

To find the base, we subtract: -5 - 2 = -7, meaning that the base equals 7.

And to find the height, we subtract: 5 - (-2) = 7, also meaning that the height equals 7 as well.

Plugging those two numbers in the equation for area, we get:

area = \(\frac{1}{2}\) 7 • 7

area = \(\frac{1}{2}\) 49

area = 24.5 or 24 1/2, in this case your answer should be B.

Step-by-step explanation:

The Total surface of triangular prism  is 112 inches.

To calculate the surface area of a triangular prism, you need the measurements of the base and the height of the triangular faces, as well as the length of the prism.

The given measurements are;

Base ; 5 inches and  4 inches

height is 8 inches

Length of the prism is 2 inches.

To find the total surface area, we sum up the areas of all the faces:

Total surface area = area of triangular  faces + area of rectangular faces + area of lateral faces.

area of triangular faces = 5 inches × 4 inches = 20 inches.

area of the two faces = 20 ×2 =40

Area rectangular faces = 5 inches × 8 inches/ 2 = 40 inches.

Area of lateral faces = 8 inches ×2 = 16 square inches

for the two lateral faces is 16 × 2 = 32 square inches.

Total surface area = 40 square inches + 40 inches + 32 square inches = 112 square inches.

The  values of x will f(x) > 0 for x < 0, and f(x) < 0 for -6 < x < 0 and x > -6.

To determine the values of x for which f(x) > 0, we need to find the intervals where the function is positive. Let's analyze the function f(x) = x*-x³-6x².

First, let's factor out an x from the expression to simplify it: f(x) = x(-x² - 6x).

Now, we can observe that if x = 0, the entire expression becomes 0, so f(x) = 0.

Next, we analyze the signs of the factors:

1. For x < 0, both x and (-x² - 6x) are negative, resulting in a positive product. Hence, f(x) > 0 in this range.

2. For -6 < x < 0, x is negative, but (-x² - 6x) is positive, resulting in a negative product. Therefore, f(x) < 0 in this range.

3. For x > -6, both x and (-x² - 6x) are positive, resulting in a negative product. Thus, f(x) < 0 in this range.

Answer:

The circumference of circle is 14π cm.

Step-by-step explanation:

Given that the formula of circumference is C = 2×π×r where r represents radius of circle. In this case, diameter of circle is 14cm so the radius will be 7cm. Then, you have to substitute the value into the formula :

\(c = 2 \times \pi \times r\)

\(let \: r = 7\)

\(c = 2 \times \pi \times 7\)

\(c = 14\pi \: \: cm\)

Answer:

14\(\pi\)

units = cm

Step-by-step explanation:

circumference = 2 x \(\pi\) x r

c = 2 x \(\pi\) x 7   - it's 7 because the diameter is 14 and radius is half the diameter

c = 14 x \(\pi\)

c = 43.98229715

in terms of pi c = 14 \(\pi\)

There are 3 internal nodes with degree 4 and 10 internal nodes with degree 3 in the tree t.

Let x be the number of internal nodes with degree 4, and y be the number of internal nodes with degree 3.

1. x + y = 13 (total internal nodes)
2. 4x + 3y = t - 1 (sum of degrees of internal nodes)

Since t has 24 leaves and 13 internal nodes, there are 24 + 13 = 37 nodes in total. So, t = 37 and we have:

4x + 3y = 36 (using t - 1 = 36)

Now, we can solve the two equations:

x + y = 13
4x + 3y = 36

First, multiply the first equation by 3 to make the coefficients of y equal:

3x + 3y = 39

Now, subtract the second equation from the modified first equation:

(3x + 3y) - (4x + 3y) = 39 - 36
-1x = 3

Divide by -1:

x = -3/-1
x = 3

Now that we have the value of x, we can find the value of y:

x + y = 13
3 + y = 13

Subtract 3 from both sides:

y = 13 - 3
y = 10

So, there are 3 internal nodes with degree 4 and 10 internal nodes with degree 3 in the tree t.

Using quantifiers; a) ∀ student ∈ this class, ∃ exactly 2 mathematics classes ∈ this school that the student has taken and b) ∃ person, ∀ country ∈ the world (country ≠ Libya), the person has visited that country.

a) "Every student in this class has taken exactly two mathematics classes at this school."

In this statement, we have two main quantifiers:

Universal quantifier (∀): This quantifier denotes that we are making a statement about every individual student in the class. It indicates that the following condition applies to each and every student.

Existential quantifier (∃): This quantifier indicates the existence of something. In this case, it asserts that there exists exactly two mathematics classes at this school that each student has taken.

So, when we combine these quantifiers and their respective conditions, we get the statement: "For every student in this class, there exists exactly two mathematics classes at this school that the student has taken."

b) "Someone has visited every country in the world except Libya."

In this statement, we also have two main quantifiers:

Existential quantifier (∃): This quantifier signifies the existence of a person who satisfies a particular condition. It asserts that there is at least one person.

Universal quantifier (∀): This quantifier denotes that we are making a statement about every individual country in the world (excluding Libya). It indicates that the following condition applies to each and every country.

So, when we combine these quantifiers and their respective conditions, we get the statement: "There exists at least one person who has visited every country in the world (excluding Libya)."

In summary, quantifiers are used to express the scope of a statement and to indicate whether it applies to every element or if there is at least one element that satisfies the given condition.

Therefore, Using quantifiers; a) ∀ student ∈ this class, ∃ exactly 2 mathematics classes ∈ this school that the student has taken and b) ∃ person, ∀ country ∈ the world (country ≠ Libya), the person has visited that country.

Step-by-step explanation:

The opposite of any positive number is the same number but negative.

The parameter u in a paired t procedure represents the mean difference in the responses to the two groups within pairs of subjects in the entire population.

This means that u captures the average change or effect observed when comparing the two related groups.

To elaborate further:

The parameter u represents a specific measure of interest in a paired t procedure.  In a paired t procedure, the data consists of paired observations, where each observation is made on the same subject or item under different conditions.

The parameter u represents the mean difference between the paired observations for the entire population. It quantifies the average change or effect observed between the two groups being compared within the pairs of subjects. By estimating the value of u from a sample, we can make inferences about the population parameter and test hypotheses regarding the difference between the two groups.
