Step-by-step explanation:

45 pieces of 4 inch can the dressmaker cut from 5 of these rolls of ribbon.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

1 roll = 3 feet of ribbon

So, 5 rolls = 5 x 3 = 15 feet of ribbon

and, 1 foot = 12 inches

Then, 15 feet = 15 x 12 = 180 inches

The dressmaker has 180 inches of ribbon in total.

Now, the 4-inch pieces can the dressmaker cut from 5 of these rolls of

Answer: In summary, all integers can be classified as either positive, negative, or zero.

Step-by-step explanation:

There are three types of integers: positive integers, negative integers, and zero.

Positive integers: Positive integers are numbers greater than zero, such as 1, 2, 3, 4, and so on.

Negative integers: Negative integers are numbers less than zero, such as -1, -2, -3, -4, and so on.

Zero: Zero is an integer that is neither positive nor negative. It is the only integer that is neither positive nor negative, and it is often referred to as the "origin" on a number line.

In summary, all integers can be classified as either positive, negative, or zero.

Answer: The three types of integers are Zero (Neutral Integers), Negative Integers, and Positive Integers.

Step-by-step explanation:

Negative Integers are the ones that has a value less than zero, examples of these are -7, -8, -9.

Positive integers, on the other hand. Are the ones that has a value more than zero, examples of these are 10, 11, 12, 13.

Note: The key difference between Negative Integers and Positive Integers is that a negative integer has a "-" sign, while a positive integer does not.

Zero are the neutral integers which means that it's the integer that's in the middle of the positive and negative integers, it has neither a positive sign or a negative sign.

Another note: Integers do not include fractions or decimals, only whole numbers.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial f(x) = 2x³ - 11x² - 20x - 7.

Now, If f(7) = 0 then (x - 7) is a factor of the polynomial f(x).

Therefore, f(x) = (x - 7)(2x² + 3x + 1).

Answer:

The drama club receives $9 for each ticket they sell.

Step-by-step explanation:

The total amount of money the drama club receives from selling 108 tickets is the difference between the total amount collected and the amount donated to the school.

Total amount collected = 108x + 972

Amount donated to the school = 108x

Amount received by the drama club = (108x + 972) - 108x = 972

Therefore, the drama club receives a fixed amount of $972 for selling 108 tickets.

To find how much money the drama club receives for each ticket sold, divide the total amount received by the number of tickets sold:

972/108 = $9

Therefore, the drama club receives $9 for each ticket they sell.

vertical angle theorem

angle addition postulate

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

The evidence in the proof that supports the statement that m/AOW = 45° is:

Statement 3: ZZOB ZXOA. This means that ZOB and ZOA are vertical angles, which means they are congruent.

Statement 4: m/XOA = 45°. This is the measure of ZOA, which is congruent to ZOB.

Statement 7: m/XOA + m/AOW = m/XOW. This is the angle addition postulate, which states that the sum of the measures of the angles in a triangle is 180°.

So, combining these pieces of evidence, we have:

m/XOA = 45° and m/XOA + m/AOW = m/XOW,

therefore m/AOW = m/XOW - m/XOA

                              = 90° - 45°

                              = 45°.

The boolean expression that is true if the value of x is equal to zero is:

x == 0

Let's us first learn about Boolean expression.

A boolean expression is an expression that evaluates to either true or false. It can be created using comparison operators, such as == (equal to), != (not equal to), < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to). These operators compare two values and return a boolean result.

In this question, the double equal sign (==) is the comparison operator for equality in many programming languages, and it returns true if the values on both sides are equal, and false otherwise.

So in this case, the expression "x == 0" would return true if x is equal to zero, and false otherwise.

  b. Square the number of the next term, n

Step-by-step explanation:

You want to know the pattern of the sequence 1, 4, 9, 16, 25, ... and why it tells you the next number is 36.

Usually we look for a common difference or a common ratio when we're trying to identify a sequence as arithmetic or exponential. This sequence has neither, as the differences are 3, 5, 7, 9, and the ratios are 4, 9/4, 25/16.

Neither of these are constant sequences. However, we do notice that the sequence of differences has a common difference of 2. The fact that "second differences" are common (all the same) means the sequence can be described by a second-degree polynomial.

Looking at the sequence values, we see they are ...

  1 = 1², 4 = 2², 9 = 3², 16 = 4², 25 = 5²

so we expect the 6th term to be the square of 6, 6² = 36. This is in line with the predicted next number.

The Morse Fall Scale (MFS) is a standardized tool used to assess a patient's risk of falling. It is used by healthcare professionals in a variety of clinical settings, including hospitals, long-term care facilities, and home care.

The MFS was first developed in 1987 by Dr. Morse and her colleagues as a way to identify patients at high risk for falls and to implement fall prevention measures. The MFS is a quick and simple tool that assesses six different risk factors for falls. These risk factors include history of falling, secondary diagnosis, ambulatory aids, intravenous therapy, gait, and mental status. The MFS assigns points to each risk factor based on the severity of the risk, with a maximum score of 125. Patients who score higher on the MFS are considered to be at higher risk for falls and require more intensive fall prevention interventions. The MFS is useful for healthcare professionals in identifying patients at risk for falls and in developing an individualized fall prevention plan. The MFS is also useful in measuring the effectiveness of fall prevention interventions by allowing healthcare professionals to track a patient's progress over time. However, it is important to note that the MFS is only one tool in a comprehensive fall prevention program and should not be used in isolation.

In summary, the Morse Fall Scale is a standardized tool used to assess a patient's risk of falling. It is a simple and quick tool that assesses six different risk factors and assigns points based on the severity of the risk. The MFS is useful in identifying patients at risk for falls and in developing an individualized fall prevention plan.

Answer:

Step-by-step explanation:

The sum of the interior angles in a polygon can be calculated using the following formula:

(n - 2) * 180 degrees

where n is the number of sides in the polygon.

To understand why this formula works, let's consider a single interior angle in the polygon. Each interior angle is split into two equal angles that form a straight line. The sum of these two angles is 180 degrees. Now, if we look at all the interior angles in the polygon, we can see that they are divided into (n - 2) pairs of angles that form straight lines. This means that the sum of all the interior angles in the polygon is (n - 2) * 180 degrees.

For a hexagon, which has 6 sides, we can plug in n = 6:

(6 - 2) * 180 = 4 * 180 = 720 degrees

So, the sum of the interior angles in a hexagon is 720 degrees.

+10m deep = +100 kPa

50m deep = 600 kPa

60m deep = 700 kPa

The depth affects the entire water pressure, not the other way around, and thus the depth is a independant variable and the water pressure is most likely a dependant variable.

Fact:
