Answer:

x = 50

Step-by-step explanation:

The interior angle at each vertex of regular octagons are 135°.

3(50) - 15 = 135

For the polygon to be an 8 sided regular polygon like you said, the angle must equal 135, and so x must equal 50.

The required value of the x in the given expression is 50°.

Given that,
A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.

A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of polygons, equilateral triangles, squares, pentagons, etc

Here,
For the octagon,
The angle of a vertex is 135°.
Equating the angles,
3x  -15 = 135
3x = 135 + 15
3x = 150
x = 50

Thus, the required value of the x in the given expression is 50°.

Answer:

Kevin is 7 years old right now.

Step-by-step explanation:

Let x be Kevin's age right now, that's what we're trying to find.

Answer:a) To find the probability that Jane will not take out three fruits and have an orange, an apple, and a grapefruit, we need to calculate the probability of the complementary event, which is the probability that she will take out any combination that doesn't include those three specific fruits.Total number of fruits = 5 oranges + 4 grapefruits + 3 apples = 12 fruitsNumber of ways to select 3 fruits from the 12 fruits = C(12, 3) = 12! / (3! * (12 - 3)!) = 220Number of ways to select 3 fruits excluding the orange, apple, and grapefruit = C(9, 3) = 9! / (3! * (9 - 3)!) = 84Probability of not selecting the specific combination = 84 / 220 ≈ 0.3818Therefore, the probability that Jane will not take out three fruits and have an orange, an apple, and a grapefruit is approximately 0.3818.b) To find the probability that Jane will not take out an orange until all five oranges are removed and all other fruits remain in the bag, we can consider the scenario where she removes all other fruits first. The probability of not selecting an orange on each draw is:Probability of not selecting an orange = (Total fruits - Oranges) / Total fruits = (4 grapefruits + 3 apples) / 12 fruits = 7 / 12Since Jane removes one fruit at a time without replacement, the probability of not selecting an orange on each draw remains the same.The probability of not selecting an orange in all five draws is:Probability of not selecting an orange in 5 draws = (7 / 12) * (7 / 12) * (7 / 12) * (7 / 12) * (7 / 12) ≈ 0.0864Therefore, the probability that Jane will not take out an orange until all five oranges are removed and all other fruits remain in the bag is approximately 0.0864.

Step-by-step explanation:

The probability that Jane will not take out three fruits and have an orange, an apple, and a grapefruit is approximately 0.3818 or 38.18%.

The probability that Jane will not take out an orange, leave it to the side, remove another orange, and continue until all five oranges are removed while leaving the other fruits in the bag is 0, indicating that it is not possible for this event to occur.

We have,

a)

To calculate the probability that Jane will not take out three fruits and have an orange, an apple, and a grapefruit (order doesn't matter), we need to consider the total number of ways she can choose three fruits out of the available fruits.

Total number of ways to choose 3 fruits

= Total number of fruits Choose 3

= (5 + 4 + 3) Choose 3

= 12 Choose 3 = 220

Now, let's calculate the number of ways she can choose three fruits that do not include an orange, an apple, and a grapefruit.

Since we want to exclude these specific fruits, we have:

Number of ways to choose 3 fruits without an orange, an apple, and a grapefruit

= Number of fruits remaining (excluding the specified fruits) Choose 3

= (12 - 3) Choose 3

= 9 Choose 3

= 84

The probability that Jane will not take out three fruits an orange, an apple, and a grapefruit is given by:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = Number of ways to choose 3 fruits without specified fruits / Total number of ways to choose 3 fruits

Probability = 84 / 220 ≈ 0.3818 or 38.18%

b)

To calculate the probability that Jane will not take out an orange and remove all five oranges while leaving the other fruits in the bag, we need to consider the total number of ways she can remove five oranges.

Total number of ways to remove 5 oranges = Number of oranges Choose 5 = 5 Choose 5 = 1

Now, let's calculate the number of ways she can remove the oranges while leaving the other fruits in the bag. Since we want to exclude an orange each time until all five oranges are removed, we have:

Number of ways to remove 5 oranges without affecting other fruits = Number of oranges remaining (excluding the ones removed) Choose 5 = (5 - 5) Choose 5 = 0 Choose 5 = 0

The probability that Jane will not take out an orange and remove all five oranges while leaving the other fruits in the bag is given by:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = Number of ways to remove 5 oranges without affecting other fruits / Total number of ways to remove 5 oranges

Probability = 0 / 1 = 0

Therefore,

The probability that Jane will not take out three fruits and have an orange, an apple, and a grapefruit is approximately 0.3818 or 38.18%.

The probability that Jane will not take out an orange, leave it to the side, remove another orange, and continue until all five oranges are removed while leaving the other fruits in the bag is 0, indicating that it is not possible for this event to occur.

Answer:

y=4x-6

Step-by-step explanation:

The equation of the line is y=mx+c where m is the slope and c is the intercept.

To find the slope, take two points \((x_{1},y_{1})\) and \((x_{2},y_{2})\) and use the equation \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\). Let's take (1,-2) and (2,2) as our two points:

\(m=\frac{2-(-2)}{2-1}=\frac{4}{1}=4\)

The y-intercept is where the line crosses the y-axis. We can see from the graph that the line crosses the y-axis at -6, therefore c= -6.

Now we can write the equation of this line: y=4x-6

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer:

Reena has a square office with an area of 126 square feet. Jazmine has a square office with an area that is 50% greater than the area of Reena’s office. To the nearest tenth, how much greater is the side length of Jazmine’s office than the side length of Reena’s office?

To find the side length of Jazmine's office, we need to first determine the area of her office. We know that her office has an area that is 50% greater than Reena's office, which means the area of Jazmine's office can be calculated as follows:

Area of Jazmine's office = (1 + 0.5) * Area of Reena's office Area of Jazmine's office = 1.5 * 126 square feet Area of Jazmine's office = 189 square feet

Since Jazmine's office is also square, we can find the side length by taking the square root of the area:

Side length of Jazmine's office = sqrt(189) feet Side length of Jazmine's office ≈ 13.7 feet

To find how much greater the side length of Jazmine's office is than the side length of Reena's office, we simply subtract the side length of Reena's office (which is also the square root of her office's area) from the side length of Jazmine's office:

Side length difference = Side length of Jazmine's office - Side length of Reena's office Side length difference = sqrt(189) feet - sqrt(126) feet Side length difference ≈ 1.8 feet

Therefore, to the nearest tenth, the side length of Jazmine's office is 1.8 feet greater than the side length of Reena's office.

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Step-by-step explanation:

-255/-17=15

Based on the future dates concept, and the available content of the question, it will take 15 years for the change in length of the island to be -255 inches.

Future date is a term that is used to describe the major activities of a certain place or humans.

In this case, the time it takes for the change in length to be -255 inches we can set up the following equation:

Change in length = rate * time

-255 inches = -17 inches/year * time

To solve for time divide both sides of the equation by -17 inches/year:

time = -255 inches / (-17 inches/year)

Simplifying the expression:

time = 15 years

Therefore, in this case, it is concluded that it will take 15 years for the change in length of the island to be -255 inches.

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

Step-by-step explanation:

The amount for Sean owe in tax will be $3,150.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Sean earned $31,000 last year.

In the first $25,000 is taxed at 9% and income above is taxed at 15%.

Now,

Since, In the first $25,000 is taxed at 9%.

Hence, The amount of tax = 9% of $25,000

                                         = 9/100 × $25,000

                                         = $2,250

And, Income above is taxed at 15%.

Hence, The above income = $31,000 - $25,000

                                          = $6,000

So, The tax for above income = 15% of $6,000

                                              = 15/100 × 6,000

                                              = $900

Thus, The total tax = $2,250 + $900

                             = $3,150
