1/2 minus (1/8+1/8) I need help can somebody give me advice on this

The perimeter of the given triangle in mixed fraction form is 4 1/2 ft.

A triangle is a closed, 2-dimensional shape with three straight sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. There are many types of triangles, including equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), scalene triangles (no sides or angles are equal), right triangles (one angle is a right angle, or 90), and obtuse triangles (one angle is greater than 90). Triangles are used in many areas of mathematics, science, and engineering.

Here,

The perimeter of the triangle:

=2 1/8+5/6+1 3/4

First, we need to convert all the mixed numbers into improper fractions:

2 1/8 = 17/8

5/6 = 10/16 = 15/24

1 3/4 = 7/4

Now we can add the three fractions:

17/8 + 15/24 + 7/4

To add these fractions, we need to find a common denominator. The smallest number that all three denominators divide into is 24. So we can rewrite the fractions with 24 as the denominator:

17/8 = 51/24

15/24 (already in the correct form)

7/4 = 42/24

Now we can add the numerators:

51/24 + 15/24 + 42/24 = 108/24

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 12:

108/24 = (9 × 12)/(2 × 2 × 2 × 3) = 9/2

=4 1/2 ft

Answer:

Step-by-step explanation:

Prim's algorithm is a greedy algorithm used to find the minimum spanning tree (MST) of a connected, undirected graph. It works by growing the tree one vertex at a time, always adding the vertex with the lowest weight edge that connects it to the growing tree. The algorithm starts with an arbitrary vertex, adds it to the tree, and then repeats the following steps until all vertices are in the tree:

Find the vertex that is not in the tree but has the minimum weight edge connecting it to the tree.

Add the vertex to the tree and mark it as visited.

Update the minimum weight edges connecting the vertices that are not yet in the tree to the growing tree.

This process continues until all vertices are in the tree, and the final result is the minimum spanning tree. The visualization of Prim's algorithm for minimum spanning tree can be represented graphically by showing the growth of the tree one vertex at a time, and highlighting the edges that are added to the tree in each step. The animation can be used to show how the algorithm is making decisions based on the weights of the edges and how it is gradually building the minimum spanning tree.

The rate of change of the function represented in the table is 12 For the given x- and y-values, the function is f(x)=12x+34

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

m=26-2/5-3

=24/2

=12

Rate of change is 12.

Now let us find y intercept

26=12(5)+b

26=60+b

26-60=b

b=34

So the function is y=12x+34

Hence, the rate of change of the function represented in the table is 12 For the given x- and y-values, the function is f(x)=12x+34

The probability that the country is in the south Asia region is 7/87

The probability is a mathematical concept that tells us how likely an event is to occur.

The probability that a country is in South Asia given that it has high business startup costs is represented as P(A|B). This is calculated as follows:

P(A|B) = P(A and B) / P(B)

Where P(B) is the probability that a country has high business startup costs and can be calculated as:

P(B) = B / Total number of countries

And P(A and B) is the probability that a country is in South Asia and has high business startup costs, which can be calculated as:

P(A and B) = A / Total number of countries

So, substituting the values, total high startup cost is 87 and and, South Asia start up cost is 7, Then, the probability that the country is in the south Asia region is

The dimensions of the original mat are 27 inches by 21 inches.

A closed figure bounded by four sides in which opposite sides are equal is known as rectangle.

The area of rectangle is calculated by the given formula,

A = length x breadth

Length and width  of the rectangle can be found from the following expression after solving for x. The expression is given by :

outside area - inside area = 184 square inches

{(2·x - 3)·(x + 8)} - {(2·x - 7)·(x + 4)} = 184  (On substitute length and width expressions. Each area is the product of length and width.)

⇒{( 2·x² + 16·x - 3x - 24)} - {(2·x² +  8x  -7x -28) }= 184

⇒(2·x² + 13x - 24) - ( 2·x² + x -28) = 184

⇒ 12·x + 4 = 184 .................(On simplifying the expression)

⇒ 12·x = 180

⇒ x = 15

Then the original length of the mat is given by substituting value of x in outside length expression :

2·x - 3 = 2·15 - 3 = 30 - 3 = 27 inches

If A, B, and C are nxn invertible matrices, the equation   C^-1(A+X)B^-1=I(n) has a solution which is X=CB-A. Since invertible matrices are those whose inverse matrix exists.

For A to be the matrix  here A⁻¹ is the inverse of it, so AA⁻¹=I, here I is the identity matrix ,since the matrix equation given to us is: C⁻¹(A+X)B⁻¹=In, now multiplying B on the right side and  C on the left side we get :CC⁻¹(A+X)B⁻¹B=CIₙB

=>Iₙ(A+X)Iₙ=CIₙB

=>A+X=CB, according to the property  of the identity matrix.Now adding -A on both sides we get,

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

i.e

2 x 5 = 10

10 x 5 = 50

50 x 5 = 250

250 x 5 = 1250

The Zucchini will be longer than 11 feet on the ninth day.

Since 12 inches is equal to 1 foot, then 11 feet will be equal to 132 inches. Below, we are going to describe the rate of the plant's growth from day 1.

Day 1 = 6 inches

Day 2 = 6 + 9 inches = 15 inches

Day 3 = 15 + 9 + 3 = 27 inches

Day 4 = 27 + 12 + 3 = 42

Day 5 = 42 +15 + 3 = 60

Day 6 = 60 + 18 + 3 = 81

Day 7 = 81 + 21 + 3 = 105

Day 8 = 105 + 24 + 3 = 132

Day 9 = 132 + 27 + 3 = 162

We are told that on the second day, the tree grew up to 15 inches and subsequently, it grew by the same amount as the day before plus another three inches.

Going by that calculation, on the third day, the tree will grow by 9 inches plus three more inches and this continues. Finally, on the ninth day, the tree would have grown up to 162 inches which is greater than 132 inches or 11 feet.
