The majority of the marina's bolts are white. The remaining bolts are divided into 4/7 blue and the remainder red. There are 84 vessels at the marina if there are nine red boats.

Let's start by finding the fraction of bolts that are not red:

Fraction of white bolts: 3/4

Fraction of bolts that are not white: 1 - 3/4

Fraction of bolts that are not white = 4-3/4

Fraction of bolts that are not white = 1/4

Fraction of blue bolts: 4/7 of 1/4

Fraction of blue bolts = 4/28

Fraction of blue bolts = 1/7

Fraction of red bolts: 1/4 - 1/7

Fraction of red bolts = 7-4/28

Fraction of red bolts = 3/28

We know that there are nine red boats, which is equal to 3/28 of the total number of bolts. So we can set up an equation to solve for the total number of bolts:

3/28x = 9

Multiplying both sides by (28/3), we get:

x = (28/3) * 9

x = 28 * 3

x = 84

Therefore, there are 84 boats in the marina.

Using the distance formula and the converse of the pythagorean theorem to determine whether the points are vertices of a right triangle :

22. The points (1,1), (4,4), and (1,4) form a right triangle.

23. The points (6,0), (6,4), and (2,4) form a right triangle.

24. The points (-2,1), (3,5), and (6,-2) does not form a right triangle.

The points (1,1), (4,4), and (1,4) form a triangle. We can use the distance formula to find the lengths of the three sides, and then use the converse of the Pythagorean theorem to determine whether it is a right triangle. The distance formula is:

d = √((x₂-x₁)² + (y₂-y₁)²)

So the lengths of the three sides are:

d₁ = √((4-1)² + (4-1)²) = √(27)

d₂ = √((1-1)² + (4-1)²) = √(9)

d₃ = √((1-4)² + (4-1)²) = √(18)

To check if it is a right triangle, we need to see if any of the sides squared equals the sum of the squares of the other two sides. If that is the case, then it is a right triangle. Otherwise, it is not. Checking the three possible combinations, we see that:

d₁² = 27

d₂² + d₃² = 9 + 18 = 27

Therefore, the triangle formed by the points (1,1), (4,4), and (1,4) is a right triangle.

Similarly for points (6,0), (6,4), and (2,4), the lengths of the three sides are:

d₁ = √((6-6)² + (4-0)²) = 4

d₂ = √((2-6)² + (4-4)²) = 4

d₃ = √((6-2)² + (0-4)²) = 4√2

To check :

d₁² + d₂² = 16 + 16 = 32

d₃² = 32

Therefore, the triangle formed by the points (6,0), (6,4), and (2,4) is a right triangle.

For points (-2,1), (3,5), and (6,-2) the lengths of the three sides are:

d₁ = √((3-(-2))² + (5-1)²) = √(41)

d₂ = √((6-3)² + (-2-5)²) = √(58)

d₃ = √((6-(-2))² + (-2-1)²) = √(73)

To check :

d₁² + d₂² = 41 + 58 = 99

d₃² = 73

Therefore, the triangle formed by the points (-2, 1), (3,5), and (6, -2) is not a right triangle.

The cost increases by $10 for each ton of sugar being transported. This can be seen from the fact that for every 1 ton increase in weight, the cost increases by $10. And the slope of the line is $10/ton.

(a) To calculate the cost increase per ton of sugar being transported, we need to find the change in cost when the weight of sugar increases by 1 ton.

Looking at the graph, we can see that the cost increases from $20 to $30 as the weight of sugar increases from 1 ton to 2 tons. Therefore, the cost increase per ton of sugar is:

$30 - $20 = $10

So the cost increases by $10 for each ton of sugar being transported.

(b) The slope of the line can be calculated using the formula:

slope = (change in y) / (change in x)

where y is the cost and x is the weight of sugar being transported.

Since the line is perfectly horizontal, the change in y is zero for any change in x. Therefore, the slope is:

slope = 0 / (change in x) = 0

So the slope of the line is zero, which means that the cost does not change as the weight of sugar being transported changes.

The answer of the given question based on the finding the adjoint of M is 16  -4  -33

  -12  -5  -12.

In linear algebra, a cofactor is a scalar value that can be computed for each element of a square matrix. To find the cofactor of a specific element of a matrix, we first remove the row and column containing that element, and then compute the determinant of the remaining matrix. The sign of the cofactor depends on the position of the element within the matrix: it is positive if the sum of the row and column indices is even, and negative if the sum is odd.

The cofactor matrix of a given matrix is obtained by replacing each element of the matrix with its corresponding cofactor. Cofactor matrices are useful in computing the inverse of a matrix and in solving systems of linear equations.

The adjoint of  matrix is  transpose of its co-factor matrix.

First, we need to find the transpose of the co-factor matrix:

What is mixed fraction?

A mixed number is one that contains both a whole number and a fraction. The fraction is written after the whole number, with a space or plus sign placed between them. The mixed number 2 1/4 serves as an explanation for how the numbers 2 and 1/4 were added. Objects that aren't whole numbers but are close to them, such length or time measurements, are typically represented by mixed numbers.

a) Diagram

   4 cups of blueberries

    __ __ __ __

    |    |     |    |    |

    |__|__|__|__|

Each batch uses 3/2 cups of blueberries

B) To find the number of batches Lin can make, we need to divide the total amount of blueberries by the amount of blueberries per batch:

4 cups of blueberries ÷ (3/2 cups of blueberries per batch)

= (4 cups of blueberries) × (2/3 batches per cup of blueberries)

= 8/3 batches

Therefore, Lin can make 8/3 or approximately 2.67 batches of blueberry muffins using all of the blueberries.

C) To find the fraction of a batch Lin will need to make in order to use all of the blueberries, we need to subtract the number of whole batches from the total number of batches:

8/3 batches - 2 batches = 2/3 of a batch

Therefore, Lin will need to make 2/3 of a batch in order to use all of the blueberries.

Using derivative of a function

The derivative of a function is its limit as the change in the independent variable tends to zero.

Now, since we have the [tex]\lim_{h \to 0}\frac{cos(\pi + h) - (- 1)}{h}[/tex].

We know that the definition of the derivative of  a function f(x) is

[tex]f'(x) =\lim_{h \to 0}\frac{f(x + h) - f(x)}{h}[/tex]

Now, comparing both equations, we see that

f(x + h) = cos(x + h), f(x) = -1

Now, since f(x + h) = cos(x + h), we notice that f(x) must be a cosine function.

So, f(x) = cosx

Now, f(a) = -1

cosa = -1

a = cos⁻¹(-1)

= π

So, substituting this into the derivative equation, we have

[tex]f'(x) =\lim_{h \to 0}\frac{f(x + h) - f(x)}{h}[/tex]

[tex]f'(x) =\lim_{h \to 0}\frac{cos(x + h) - (-1)}{h}\\=\lim_{h \to 0}\frac{cos(x + h) - cos(x)}{h}\\=\lim_{h \to 0}\frac{cos(\pi + h) - cos(\pi )}{h}\\= -sin\pi \\= 0[/tex]

The function (f . g)(x) is a composite function. Composite function is a function that depends on another function. In other words, composite function is a function that is within another function

Therefore, let's solve the composite function as follows:

f(x) = x³ - 4x + 2

g(x) = x² + 2

Hence,

(f. g)(x) = f(x) × g(x)

f(x) × g(x) = (x³ - 4x + 2)(x² + 2)

Using arithmetic progression, number of logs in 6th row are 33.

We can use the information that each row has 5 fewer logs than the row below it to create a sequence of the number of logs in each row. Let's call the number of logs in the first row "a" (which we know is 58 logs). Then, the number of logs in the second row will be "a - 5", the number of logs in the third row will be "(a - 5) - 5" or "a - 10", and so on.

So, we have the sequence of the number of logs in each row as:

a, a - 5, a - 10, a - 15, a - 20, ...

To find the number of logs in the 6th row, we need to find the 6th term in this sequence. We can use the formula for the nth term of an arithmetic sequence:

an = a₁ + (n - 1)d

where an is the nth term, a1 is the first term, n is the number of the term we want to find, and d is the common difference between terms (which is -5 in this case, since each row has 5 fewer logs than the row below it).

Substituting the given values, we get:

a₆ = a₁ + (6 - 1)(-5)

= a - 25

So, the number of logs in the 6th row is a - 25. Since we know that a is 58 logs, we can substitute and simplify:

a - 25 = 58 - 25 = 33

Therefore, the answer is (b) 33.

In mathematics, ratios show how frequently one number is contained in another. For example, if there are 8 oranges and 6 lemons in a fruit dish, the ratio of oranges to lemons is 8 to 6. In a similar vein, the orange-to-whole-fruit ratio is 8, while the lemon-to-orange ratio is 6:8. A ratio is an ordered pair of numbers a and b expressed as a / b, where b is not zero. A ratio is an equation that equates two ratios. For example, if there is one boy and three girls (for every boy she has three girls), 3/4 are girls and 1/4 are boys.

(a) The ratio of green apples to all the apples in the basket is:

Green apples : Total apples = 9 : (9+5) = 9 : 14

So the ratio of green apples to all the apples in the basket is 9:14.

A pyramid is a polygon formed by connecting points known as bases and polygonal vertices. For each hace and vertex, a triangle known as a face is formed. A cone with a polygonal shape. A pyramid with a floor and n pyramids has n+1 vertices, n+1 vertices, and 2n edges. Every pyramid is dual in nature. A pyramid contains three dimensions. A pyramid is made up of a flat tri face and a polygonal base that come together at a single point known as the vertex. A pyramid is formed by connecting the base and peak. The base's edges form triangle faces known as sides that connect to the top.

To determine how much glass is required to cover the entire pyramid, we must first determine the total surface area of the pyramid, including the base.

The formula for calculating the surface area of each triangular face is:

(1/2) x width x height

27.31 square feet = (1/2) x 7 feet x 7.79 feet

24 square feet = (1/2) x 6 feet x 8 feet

Simply multiply the length and width to find the area of the rectangular base:

7 feet by 6 feet equals 42 square feet

As a result, the total surface area of the pyramid is:

145.62 square feet = 2 (27.31 square feet) + 2 (24 square feet) + 42 square feet

Answer:

Step-by-step explanation:

So are given that ΔBIG is similar to ΔMOP. This means that their respective angles are the same measurements, but different side lengths. By definition of similar triangles, their respective side lengths are equal in proportion.

∠I corresponds to ∠O, so their measurements are equal. w = 126°.

∠B corresponds to ∠M, so their measurements are also equal. We don't know the angle measurement for x, but we have all the angles for two similar triangles, so we can find the measure of the third angle. The total angle measure for any triangle is 180°.

x = 180 - 24 - 126

x = 30°

Now that we have all the angle measurements, we can proportions to calculate the lengths of the unknown sides. The proportion of ΔBIG to ΔMOP can be calculated using the corresponding side length for each triangle.

Segment BG corresponds to segment MP. The proportion of BG to MP is:

48/72. Proportions are fractions, so this ratio can be simplified to 2/3 (divide by 24 on top and bottom).

Now we know that the ratio of ΔBIG to ΔMOP is 2/3.

Segment BI (aka v) = (2/3) * 60 cm

v = 40 cm

Segment PO (aka y) * (2/3) = 42 cm

y = 42 * 1.5
