A hurricane is a big rotating storm system that develops over warm ocean waters and usually travels westward toward the American mainland.

An Atlantic Ocean hurricane or a northern Pacific Ocean hurricane is a tropical storm. In most years, hurricanes develop between June 1 and November 30. The Taino Indian word "hurakan," which means "god of wind," is where the word "hurricane" originates.

A hurricane is a big rotating storm system that develops over warm ocean waters and usually travels westward toward the American mainland. Depending on the maximum sustained wind speeds, hurricanes are either classed as tropical storms or hurricanes. Hurricanes have winds of 74 mph or more, whereas tropical storms have winds of 39 to 73 mph.

The hurricane's eye, which is a calm, clear region encircled by powerful winds, is the most hazardous component of the storm. The hurricane's eye, which can be up to 30 miles across, frequently experiences the storm's greatest rains and highest winds.

A hurricane's landfall can result in flooding from storm surges, strong winds, and heavy rains. The increase in sea level that happens as a cyclone nears land is known as a storm surge. Along with coastal locations, this increase in water level has the potential to inflict significant harm and flooding.

After 8 number of games both has equal amount of money.

Deana starts with $15 and the machine she is playing costs $0.75 per game

lulu starts with $13 and the machine she is playing costs $0.50 per game

Let us after x number of games both has same money

Deana spends 0.75*x amount of money after playing x number of games.

Deana has remaining amount of money 15 - 0.75*x.

lulu spends 0.50*x amount of money after playing x number of games.

lulu has remaining amount of money 13 - 0.50*x.

We have assumes that after x number of games both has same amount of money.

[tex]15-0.75*x = 13 - 0.50*x[/tex] --- this is the correct expression to write an equation that could be used to find after how many games the two friends will have the same amount of money.

15 - 13 = 0.75*x - 0.50*x

solving the equation, the width of the rectangle was found to be 6.67 feet and the length was found to be 22.67 feet.

Let x = the width of the rectangle

Then, the length = 3x + 4

Perimeter = 2(3x + 4) + 2x = 48

2(3x + 4) + 2x = 48

6x + 8 = 48

6x = 40

x = 40/6

x = 6.67 feet

The width of the rectangle = 6.67 feet

The length of the rectangle = 3(6.67) + 4 = 22.67 feet

To solve for the length and width of the rectangle, an equation was set up using the perimeter of 48 feet. The length was represented by 3x + 4, where x is the width. After solving the equation, the width of the rectangle was found to be 6.67 feet and the length was found to be 22.67 feet.

Hello,

I hope you and your family are doing well!

An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. In this case, the difference between consecutive terms is 6, so the common difference is 6.

The explicit formula for the nth term of an arithmetic sequence with first term a1 and common difference d is:

a_n = a1 + (n-1)d

Plugging in the values from the given sequence, we have:

a_n = 7 + (n-1)6

This is the explicit formula for the nth term of the arithmetic sequence.

For example, if you want to find the fifth term of the sequence, you would plug in n = 5:

a_5 = 7 + (5-1)6 = 7 + 4*6 = 7 + 24 = 31

So the fifth term of the sequence is 31.

There are 15 different positive divisors (greater than 1) for the number m³pt. Here m, p, and t are distinct prime numbers. This is obtained by the prime factorization method.

The following are the steps to find the number of positive factors of a number:

Step 1: Find the L.C.M of the number by using the prime factorization method. For example: consider the number 24. Then, its prime factorization is as follows:

24 = 2 × 2 × 2 × 3

Step 2: Same bases should be added in powers. So, the factors we can write as

24 = 2³ × 3¹

Step 3: To find the number of positive factors of the number, the exponents of the prime factors is multiplied by adding 1.

I,e., N = (3 + 1)(1 + 1) = 4 × 2 = 8.

So, there are 8 factors for the number 32. They are 1, 2, 3, 4, 6, 8, 12, and 24.

It is given that, m, p, and t are distinct positive prime numbers.

Then, the number of positive divisors greater than 1 for the number m³pt are

m³× p × t

Since m, p, and t are prime factors, we can multiply their power by adding 1 to them. I.e.,

N = (3 + 1) (1 + 1) (1 + 1) = 4 × 2 × 2 = 16

So, there are a total of 16 factors for the given number (including 1). So, the number of factors greater than 1 is 16 - 1 = 15.

Therefore, there are 15 different positive divisors greater than 1 for the number having prime factors as m³pt.

What is right triangle?

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

Given that point A is lie on the bisector of ∠PQR.

When anything is divided into two equal or congruent portions, usually by a line, it is said to have been bisected in geometry. The line is then referred to as the bisector. Segment bisectors and angle bisectors are the sorts of bisectors that are most frequently taken into consideration.

Therefore QA is the bisector of ∠PQR

Then ∠PQA   ≅ ∠RQA  

Since ∠QXA and ∠QYA are right angle, therefore they are congruent.

∠QXA ≅ ∠QYA

QA ≅ QA

AAS postulate: The triangles are congruent if two angles and the excluded side of one triangle match two angles and the excluded side of another triangle.

According to AAS postulate,

△PQA ≅ △RQA  

Point A is equidistance from ∠PQR.

Step-by-step explanation:

If more than 25 people are added, the total revenue will be r(x) = $ 50, with the x = 5 size group producing the highest revenue for the agency.

The law of diminishing returns dictates that marginal revenue will eventually begin to decline as output level rises, even though it can remain constant above a certain threshold of output.

calculation

If a group of 25 people or more, a travel agency will organize the excursion.

The cost is $300 per person, if the group has exactly 25 participants. However, the cost per person drops by $10 for each additional person beyond the calculated maximum of 25.

R(X) = ( 25 + x ) ( 300 - 10x ) ( 300 - 10x )

evaluate in relation to x = R'(X) = 300 - 10x - 250 - 10x = 50 - 20x

We now have 30 people, which means that there are 5 more persons than 25.

Marginal revenue equals $50 when x = 5 and R'(X) = 50 - 20(5).

The revenue will drop by $50 for the following individual (31st ).

If more than 25 people are added, the total revenue will be r(x) = $ 50, with the x = 5 size group producing the highest revenue for the agency.

When the 10% criterion is met, we can use a binomial distribution to approximate the number of successes in a simple random sample (SRS) (as a simple random sample selects the trials without replacement).

The sample must be less than 10% of the population in order to satisfy the 10% requirement. It is fair to presume that the trials are independent because the sample is so much smaller than the population (even though the sampling occurred without replacement).

This suggests that the sample size n in this situation must be less than 10% of the population size NN.

This is the reason why 10% condition should be met.

In a binomial probability distribution, the number of successes in a series of n experiments is represented as either success or failure   (probability q = 1 p), depending on the outcome's boolean value. A Bernoulli trial or experiment is another name for a single success or failure test, while a Bernoulli process is another name for a sequence of results.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (8, 2).

And, The slope of perpendicular line is,

⇒ m = - 4

Now,

Since, The equation of line passes through the point (8, 2).

So, We need to find the slope of the line.

Since, The product of slope of the perpendicular line is - 1.

Hence, Slope of the line is,

m = - 1/- 4

m = 1/4

Thus, The equation of line with slope 1/4 is,

⇒ y - 2 = 1/4 (x - 8)

⇒ y - 2 = 1/4 (x - 8)

⇒ y - 2 = 1/4x - 2

⇒ y = 1/4x
