Answer:

  x = 6

Step-by-step explanation:

You want the value of x in the geometry where an angle bisector has divided a triangle into sides 42 and (6x-1), and corresponding sides 78 and (10x+5).

The angle bisector divides the sides of the triangle proportionally:

  (6x -1)/42 = (10x +5)/78

  13(6x -1) = 7(10x +5) . . . . . . . . multiply by 546

  78x -13 = 70x +35 . . . . . . . simplify

  8x = 48 . . . . . . . . . . . . . . add 13-70x

  x = 6 . . . . . . . . . . . . . . divide by 8

So the perimeter of the octagon is approximately 45.25 centimeters (rounded to two decimal places).

In geometry, a shape's perimeter is sometimes referred to as its total length. By adding up the lengths of all of an object's sides and borders, one can determine the circumference of something such as a form. The perimeter of a form can be calculated by adding up all of the edges' lengths. For instance, a rectangular with dimensions of 24 yards long as well as 15 yards wide will have a 78 yard perimeter.

Here,

To find the perimeter of the octagon, we need to determine the length of each side of the octagon.

First, let's find the length of the diagonal of the smaller square. We can use the Pythagorean theorem:

d²=4² + 4²=

d² = 16+16 =32

d = √32

=> d = 4√2

​

This diagonal of the smaller square is also the side length of the overlapping square.

Next, let's find the length of one of the sides of the larger square that overlaps with the smaller square. Since the length of the larger square is 6cm, the side length of the overlapping region (part of the larger square that overlaps with the smaller square) is:

6 - 4√2

Finally, the length of one of the sides of the octagon is the sum of the side lengths of the two squares that overlap, minus the side length of the overlapping square (since this side is counted twice):

=> 6 + 6 - 4√2 - 4√2 - (6 - 4√2)

Therefore, the perimeter of the octagon is:

=>8 (12 - 6√2) = 96 - 48√2

So the perimeter of the octagon is approximately 45.25 centimeters (rounded to two decimal places).

Answer:

9yd

Step-by-step explanation:

3½²-2²= √8.25=2.8

The solution of the given problem of triangle comes out to be tan ∠A = 0.25.

Triangles are called polygons if they have four quadrants or more. Its form is a simple geometric figure. When put together, the characters ABC create a right-angled triangle. When the boundaries are incompatible, Euclidean geometry generates a new rectangle with square corners. Triangles are regarded as polygons because they have three edges and three corners.

Here,

Since △ABC is a right triangle with m∠C = 90°, we know that m∠A + m∠B = 90°.

Using the fact that tan ∠B = opposite/adjacent, we can set up a ratio using a common factor, x, for the opposite and adjacent sides of ∠B:

tan ∠B = 0.25 = opposite/adjacent = x/4x

Simplifying the right side, we get:

0.25 = x/4x = 1/4

Multiplying both sides by 4x, we get:

x = 4

So the opposite side of ∠B has length x = 4, and the adjacent side has length 4x = 16.

Using the Pythagorean theorem, we can find the length of the hypotenuse of △ABC:

c² = a² + b²

c² = 4²+ 16²

c² = 256

c = √256

c = 16

Now, we can use the fact that tan ∠A = opposite/adjacent to find tan ∠A:

tan ∠A = opposite/hypotenuse = 4/16 = 1/4

Therefore, tan ∠A = 0.25.

Answer:

To make a frame with an area of 30in², Travis needs to cut out a piece of steel with an area of A = (11+2x)(6+2x)in², where x is the width of the frame. The inside of the frame must be 11in by 6in, so the width of the frame must be x = (30 - 11*6)/4 = 2.25in. The total area of the piece of steel must therefore be A = (11+2*2.25)(6+2*2.25) = 30in².

Step-by-step explanation:

To determine the value of x that will result in a final area of the frame of 30in², we can use the equation for the area of the piece of steel before cutting out the frame:

A = (11 + 2x)(6 + 2x)

We can expand this expression to get:

A = 66 + 44x + 12x^2

Since the inside of the frame has to be 11in by 6in, the area of the frame is 11 * 6 = 66in². So, we want to find the value of x that will result in the area of the piece of steel being equal to the area of the frame plus 30in². This means we want to find the value of x that will satisfy:

66 + 44x + 12x^2 = 96

Expanding the left-hand side of this equation and collecting like terms, we get:

12x^2 + 44x = 30

Dividing both sides of the equation by 12, we get:

x^2 + 3.67x = 2.5

To solve for x, we can use the quadratic formula or factoring. Once we have found the value of x, we can use it to determine the dimensions of the piece of steel before cutting out the frame.

The probability that x is between 25 and 30 is 0.087.

The cumulative distribution function (CDF) of an exponential distribution with mean 25 is given by:

F(x) = 1 - exp(-x/25)

The probability that x is between 25 and 30 can be found by evaluating the CDF at x = 30 and x = 25 and subtracting the two values:

P(25 < x < 30) = F(30) - F(25) = (1 - exp(-30/25)) - (1 - exp(-25/25))

= (1 - exp(-1.2)) - (1 - exp(-1))

About $6,000 more compound interest than simple interest is earned after 35 years, and about $12,500 more compound interest than simple interest is earned after 45 years.

What is a graph ?

A graph is a visual representation of data that shows the relationship between two or more variables. It is a way of presenting information in a clear and concise manner that makes it easy to interpret and understand.

Graphs can be used to show trends over time, compare different groups or categories, or illustrate the relationship between two or more variables.

Since the graph shows the balance for two accounts with the same principal and annual interest rate, we can assume that one account is earning simple interest while the other is earning compound interest.

To estimate the amount of compound interest earned after 35 years, we can look at the difference in balance between the two accounts at that time. From the graph, we can see that the balance for the simple interest account after 35 years is approximately $4,000, while the balance for the compound interest account is approximately $10,000. Therefore, the amount of compound interest earned after 35 years is approximately:

$10,000 - $4,000 = $6,000

To estimate the amount of compound interest earned after 45 years, we can again look at the difference in balance between the two accounts at that time. From the graph, we can see that the balance for the simple interest account after 45 years is approximately $5,500, while the balance for the compound interest account is approximately $18,000. Therefore, the amount of compound interest earned after 45 years is approximately:

$18,000 - $5,500 = $12,500

Therefore,  about $6,000 more compound interest than simple interest is earned after 35 years, and about $12,500 more compound interest than simple interest is earned after 45 years.

Using permutations and combinations, we know that a total of 60,060 different arrangements of flowers can be made in a row.

The different ways in which items from a set may be chosen, usually without replacement, to construct subsets, are called permutations and combinations.

When the order of the selection is a consideration, this selection of subsets is referred to as a permutation; when it is not, it is referred to as a combination.

Examples of permutations include arranging persons, digits, numbers, alphabets, letters, and colors.

Examples of combinations include choosing the menu, the cuisine, the clothes, the subjects, and the team.

So, we have:

3 yellow, 4 red, and 6 blue flowers.

3 + 4 + 6 = 13

Now, the number of arrangements in the row will be:

= 13!/3!4!6!

The required error interval for y(probability of picking two green

apples) is  [1/4, 1/4].

The probability of picking two green apples can be calculated by multiplying the probability of picking a green apple on the first pick by the probability of picking another green apple on the second pick, given that the first pick was a green apple.

Let's call the number of green apples in the crate G, and the number of red apples in the crate R. Based on the given information, the ratio of green to red apples is 2:1, so we have G = 2R.

The probability of picking a green apple on the first pick is G/(G + R), and the probability of picking a green apple on the second pick, given that the first pick was a green apple, is (G-1)/(G + R - 1).

Therefore, the probability of picking two green apples is:

y = (G/(G + R)) * ((G-1)/(G + R - 1)) = (G/(G + R))²

Since we know that G = 2R, we can substitute that into the equation for y to get:

y = (2R/(2R + R))² = (2/(3R + R))² = (2/4R)² = 4/16 = 1/4

So the error interval for y is [1/4, 1/4].

To calculate the probability of getting two bad pieces in a row, we multiply the probabilities of each individual bad piece:

0.04 * 0.04 = 0.0016

So the chances of getting two bad pieces are 0.0016, or 0.16%. This means that out of 100 tries, you would expect to get two bad pieces in a row 0.16 times.

It's vital to remember that independent events, like obtaining two terrible pieces, have probabilities that are determined by multiplying the individual possibilities.
