Answer:

40m deep = 500 kPa.

+10m deep = +100 kPa

50m deep = 600 kPa

60m deep = 700 kPa

( It never stops ! )

Explantion:

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:

100 kPa every 10 meters, or 10 kPa per meter.

0m deep = 100 kPa. Add 10 kPa for every meter. ( and so on )

kPa = 100 + (10x the depth in meters)

Using the variables given, p = 10d + 100.

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.

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.

The percentage of 322 out of 450 using the percentage formula was found out to be approximately 71.56%.

To find the percentage of 322 out of 450, we can use the following formula:

percentage = (part/whole) x 100

where, "part" is the value we want to express as a percentage (in this case, 322), "whole" is the total value (in this case, 450), and "x" means "multiply".

Using the formula mentioned above, we get:

percentage = (322/450) x 100

percentage = 0.7156 x 100

percentage = 71.56%

Therefore, percentage of 322 out of 450 is approximately 71.56%.

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.

The VAT percentage of a mobile price is tagged Rs 5,000 with a 12% discount and adding a certain percentage of VAT reaches Rs 4,972 is a 13% VAT Percentage.

The solution to the problem is as follows:
Step 1: Find the price of the mobile after the discount. The discount is 12% of the original price, which is Rs 5,000. So, the discount amount is:
12% of Rs 5,000 = (12/100) * 5000 = Rs 600

Step 2: Subtract the discount amount from the original price to get the price after the discount:
Rs 5,000 - Rs 600 = Rs 4,400

Step 3: Now, we need to find the VAT percentage that was added to the price after the discount to get the final price of Rs 4,972. Let the VAT percentage be x%. Then the equation is:
Rs 4,400 + x% of Rs 4,400 = Rs 4,972

Step 4: Simplify the equation and solve for x:
4400 + (x/100) * 4400 = 4972
4400 + 44x = 4972
44x = 4972 - 4400
44x = 572
x = 572/44
x = 13

Therefore, the VAT percentage is 13%.

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.

Answer:

  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 pattern is ...

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.

Step-by-step explanation:

The coordinates of the point is Q ( 22 , -24 )

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

Measure the distance between the two end points, and divide by 2.

Let A ( x₁ , y₁ ) be the first point

Let B ( x₂ , y₂ ) be the second point

The midpoint between A and B is M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

Given data ,

Let the first point be represented as P ( -2 , 8 )

Let the second point be represented as Q ( x , y )

Now , the midpoint of P and Q is M ( 10 , -8 )

where , midpoint between P and Q is M ( a , b ) where

a = ( x₁ + x₂ )/2

b = ( y₁ + y₂ ) / 2

Substituting the values in the equation , we get

10 = ( -2 + x ) / 2

Multiply by 2 on both sides of the equation , we get

-2 + x = 20

Adding 2 on both sides of the equation , we get

x = 22

And ,

-8 = ( 8 + y ) / 2

Multiply by 2 on both sides of the equation , we get

y + 8 = -16
