The value of x is √12.73 when Barrett is aware that the structure measures 32x feet in height, 46x feet in breadth, and 200 feet diagonally.
Definition of Pythagoras Theorem:
The square of the long side of a right-angled triangle is equal to the sum of the squares of the other two sides.
It is stated in this formula:
[tex](side)^2+(side)^2=(hypotenuse)^2[/tex]
Given that,
Barrett is focusing on a rectangle-shaped structure on the school's property. He is aware that the structure measures 32x feet in height, 46x feet in breadth, and 200 feet diagonally.
We must determine what x stands for.
We know that,
The height of building is 32x.
The width is 46x
The diagonal is 200 feet
So we form a triangle
From the Pythagoras theorem,
Hyp² = Side²+ Side²
200² = (32x)² + (46x)²
40000 = 1024x² + 2116x²
3140x² = 40000
x² = 12.73
Square root on both sides
x = √12.73
Therefore, The value of x is √12.73 when Barrett is aware that the structure measures 32x feet in height, 46x feet in breadth, and 200 feet diagonally.

Area = 4 * 6 = 24
Perimeter = 2 * (4 + 6) = 20
Part B: Multiply the coordinates by 3Here, we have
New = (-3, 6), (-3, -12), (9, -12), and (9, 6).
Part C: Find the new perimeter and area of the rectangle.See attachment for the points, where we have
Length = 12 and width = 18
Using area and perimeter formulas, we have
Area = 12 * 18 = 216
Perimeter = 2 * (12 + 18) = 60
Part D: Comparison of the areasThe area of the new rectangle is 9 times the previous area

Responses
3,240°
360°
3,600°
180°
Answer:
3,240°
Step-by-step explanation:
The sum of the measures of the interior angles of a polygon with n sides can be found using the formula:
(n-2) * 180°
So, for a 20-sided figure, the sum of the interior angles would be:
(20-2) * 180° = 18 * 180° = 3,240°
Using a standard deck of 52 cards, Lisa drew a card, recorded the suit of the card picked, then replaced it back in the deck. She continued this for a total of 40 draws. The table shows the frequency of each type of card drawn.
The experimental probability of not selecting a heart is (D)P(not heart) = 77.5%
How to find the experimental probability ?The experimental probability that a heart is selected is:
= Number of times hearts was selected / Number of times Lisa drew a card
= 9 / 40
This then means that the experimental probability of not selecting a heart is:
= 1 - experimental probability of selecting a heart

which rule uses actual probability distributions to determine if hiring decisions have had adverse impact on minority groups? multiple choice question. the prima facie rule the standard deviation rule the four-fifths rule the bona fide occupational qualification rule
The prima facie rule uses actual probability distributions to determine if hiring decisions have had adverse impact on minority groups.
What do you mean by prima facie rule?The "prima facie" rule refers to a legal standard or a evidentiary standard used in the field of employment discrimination law. In the context of employment discrimination, a prima facie case refers to the minimum evidence required to establish a presumption of discrimination.
The term "prima facie" comes from Latin and means "at first sight" or "on its face." In other words, a prima facie case of discrimination is established if, at first sight, the evidence suggests that discrimination has taken place. Once a prima facie case has been established, the burden of proof shifts to the employer to provide a non-discriminatory explanation for the actions in question.
It is more commonly used in legal and ethical contexts to refer to a case or argument that is initially strong enough to establish a point, but may be challenged or overcome by further evidence or argument.

A back-to-school sale offered a laptop for $379. This sale price reflected a 15% discount.
Use the equation to find the cost of the computer before the reduction in price.
(Round to the nearest cent as needed.)
If a back-to-school sale offered a laptop for $379 and this sale price reflected a 15% discount, after using the equation the cost of the computer before the reduction in price is, $446.47.
What is percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
Let's call the original cost of the laptop "x".
The equation to find the cost after a discount is:
x - x * (discount rate) = sale price
In this case, the discount rate is 15%, or 0.15. Plugging in the given values:
x - x * 0.15 = 379
Expanding the equation:
x - 0.15x = 379
0.85x = 379
Dividing both sides by 0.85:
x = 379 / 0.85
x = 446.47

If the first 4 questions are True/False and the last 4 questions are Multiple Choice (a, b, c, or d). What is the probability that they will get them all correct?
The probability of getting all 8 questions correct is 1/4096 or approximately 0.024%.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The probability of getting a True/False question correct is 1/2, since there are only two possible answers. The probability of getting a multiple-choice question correct is 1/4 since there are four possible answers.
So, for the first 4 True/False questions, the probability of getting them all correct is (1/2)⁴ = 1/16.
For the last 4 multiple-choice questions, the probability of getting them all correct is (1/4)⁴ = 1/256.
The total probability of getting all 8 questions correct is the product of the probabilities of getting each set of questions correct:
(1/16) x (1/256) = 1/4096
So, the probability of getting all questions correct is 1/4096 or about 0.024%.

How to multiply two fractions?
When multiplying fractions, you first start with the two fractions you want to multiply. You multiply the numerators (the top numbers) together, and then multiply the denominators (the bottom numbers) together. After putting the two results together as a new fraction, you may need to simplify the fraction in order to express it in its lowest terms.
Firstly , let's find the reciprocal of the divisor
Reciprocal of
3/5 is 5/3
Now, multiply it with the dividend
So,
9/10 ÷ 3/5
= 9/10 × 5/3
= 45/30
