In general, different refrigerants should not be mixed or recovered into the same cylinder.

Different refrigerants have unique chemical compositions and properties that make them incompatible with one another. Mixing different refrigerants can lead to unpredictable reactions, loss of refrigerant performance, and potential safety hazards. Therefore, it is generally recommended to avoid recovering different refrigerants into the same cylinder.

When recovering refrigerants, it is important to use separate recovery cylinders or tanks for each specific refrigerant type. This ensures that the refrigerants can be properly identified, stored, and recycled or disposed of in accordance with regulations and environmental guidelines.

The refrigerant recovery process involves capturing and removing refrigerant from a system, storing it temporarily in dedicated containers, and then transferring it to a proper recovery or recycling facility. Proper identification and segregation of refrigerants during the recovery process help maintain the integrity of each refrigerant type and prevent contamination or cross-contamination.

To maintain the integrity and safety of different refrigerants, it is best practice to recover each refrigerant into separate cylinders. Mixing different refrigerants in the same cylinder can lead to complications and should be avoided. Following proper refrigerant recovery procedures and guidelines helps ensure the efficient and environmentally responsible management of refrigerants.

Step-by-step explanation:

4,12

1,3

4/12=4

12/3=4

The point (1,3) is mapped to the point by a dilation with the origin as the center. The dilation's scale factor is 4.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.

Finding the dilation's centre point is the first step in determining the scale factor. Next, we measure the distances between the centre point and various points on the preimage and the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.

The basic formula to find the scale factor of a dilated figure is: Scale factor is equal to the difference between the dimensions of the old and new shapes.

= 4,12

= 1,3

There were 682 children's and 332 adults were admitted when the entrance charge to an park is $4 for adults and $1.50 for children.

Given that,

The entrance charge to an amusement park is $4 for adults and $1.50 for children. 351 persons visited the park on one particular day, and 1014 dollars in entrance fees were collected.

We have to find how many people and kids were allowed inside.

We know that,

We get equations as,

1.5x+4y=351 ----->equation(1)

The other equation is

x+y=1014 ----->equation(2)

Take the equation(2)

x+y=1014

y=1014-x

Substitute y=1014-x in equation(1)

1.5x+4y=351

1.5x+4(1014-x)=351

1.5x+2056-4x=351

1.5x-4x=351-2056

-2.5x=-1705

2.5x=1705

x=1705/2.5

x=682

Substitute x=682 in equation(2)

y=1014-x

y=1014-682

y=332

The slope of the line that passes through the points (0, 6) and (2, 15) is 4.5, to one decimal place.

The slope of a line is a measure of how steep the line is. It is calculated by finding the change in the y-coordinate divided by the change in the x-coordinate between two points on the line.

In this case, the change in the y-coordinate is 15 - 6 = 9, and the change in the x-coordinate is 2 - 0 = 2. Therefore, the slope of the line is 9 / 2 = 4.5.

We can also see that the line is steep because the y-coordinate changes by a larger amount than the x-coordinate when we move from one point to the next.

Here is a Python code that you can use to calculate the slope of the line:

Python

def slope(point1, point2):

 """

 Calculates the slope of a line given two points.

 Args:

   point1: A tuple of the form (x, y).

   point2: A tuple of the form (x, y).

 """

 x1, y1 = point1

 x2, y2 = point2

 return (y2 - y1) / (x2 - x1)

if __name__ == "__main__":

 point1 = (0, 6)

 point2 = (2, 15)

 slope = slope(point1, point2)

 print("The slope of the line is", slope)

Answer: There are 24 ways.

Step-by-step explanation:

All the numbers are divisible by 11, so divide all the numbers by 11 to make the problem simpler: Jo climbs a flight of 6 stairs. Jo can take the stairs 1, 2, or 3 at a time.

A recursive approach can now solve this problem. The number of ways to climb one stair is 1. There are two ways to climb 2 stairs: (1, 1) or (2). For 3 stairs, there are 4 ways: (1, 1, 1), (1, 2), (2, 1), and (3). Extending this pattern, there are 1+2+4 = 7 ways to climb up 4 stairs, 2+4+7 = 13 ways to climb up 5 stairs, and 4+7+13 = 24 ways to get up 6 stairs.  

The total number of ways by which Jo climbs the stairs at school when he can take the stairs 1, 2, or 3 at a time.

Arrangement of the things or object is mean to make the group of them in a systematic order, in all the possible ways. The number of possible ways to arrange is n!.

Here, n is the number of objects.

Every day at school, Jo climbs a flight of 6 stairs.  Jo can take the stairs 1, 2, or 3 at a time. For example, Jo could climb 3, then 1, then 2.

With one stair, there is one way to climb. With two stairs, the ways to climb are two 1-1 at a time or 2 at a time. For the three stair, there are 4 ways,

\(1+1+1,1+2,2+1,3\)

For the three stair, there are 7 possibilities he can climb the stair.

\(1+1+1+1,\;1+1+2,\;1+2+1,\;2+2\;,2+1+1\;1+3.\;3+1\)

In the same way for the 5 the stair there are 6 additional steps add in it, which makes it 13.

For the six stair for single step, we have 13 ways, for double step we have 7 ways and for triple step we have 4 ways. Thus,

\(\rm Number\; of \; ways=13+7+4\\\rm Number\; of \; ways=24\)

After 8 weeks, Faith would have $88. money saved = 40+6w

Answer:

$88 saved in 8 weeks

Step-by-step explanation:

Part 1:

You would first set up the equation 40 + (6 x 8) = t. T would be the total money saved. You would then do 6 times 8 first, as they're in parenthesis. You would get 48. You now have 40 + 48 = t. You would now add like terms, and you would get 88 = t. You would save $88 in 8 weeks.

Answer:

 Slope = -1.500/2.000 = -0.750

 x-intercept = -20/3 = -6.66667

 y-intercept = -20/4 = -5

Step-by-step explanation: Solve   4y+3x+20  = 0

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  4y+3x+20  = 0 and calculate its properties

Notice that when x = 0 the value of y is -5/1 so this line "cuts" the y axis at y=-5.00000

 y-intercept = -20/4  =  -5

When y = 0 the value of x is -20/3 Our line therefore "cuts" the x axis at x=-6.66667

 x-intercept = -20/3  = -6.66667

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -5.000 and for x=2.000, the value of y is -6.500. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -6.500 - (-5.000) = -1.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -1.500/2.000 = -0.750

 Slope = -1.500/2.000 = -0.750

 x-intercept = -20/3 = -6.66667

 y-intercept = -20/4 = -5

Answer:

C. Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)

Step-by-step explanation:

The student first made a mistake in step 2. In order to check if the sum of the measures of the two remote interior angles of a triangle is equal to the measure of the exterior angle, it is necessary to use the property of alternate exterior angles. Alternate exterior angles are angles that are on opposite sides of the transversal and between the same parallel lines, so they are congruent. The measure of alternate exterior angles is always equal to 180 degree. Therefore, the correct statement in step 2 is that m∠o + m∠p = 180 degrees (alternate exterior angles)

Here is the comparision

Purpose:To compare the topologic features of acute primary angle-closure glaucoma eyes before an attack to those of normotensive eyes, assuming that untreated fellow acute primary angle-closure glaucoma eyes are candidates for an acute attack.

Methods:Under dark-room conditions, ultrasound biomicroscopy was used to examine 50 eyes (12 fellow eyes of acute primary angle-closure glaucoma and 38 normotensive cases with a closure-possible narrow angle). Before any surgical or laser intervention, all eyes were examined and found to have normal pupillary response without the use of any topical drugs. Each eye was examined at four predetermined angle locations. The chamber angle configuration parameters were measured and compared between the two groups.

Result:Appositional angle closures were detected in 27 fellow eyes and 48 normotensive eyes with a closure-possible narrow angle. The incidence differed statistically between the two groups (69.2% in fellow eyes and 48% in normotensive eyes). In the fellow eye group, appositional angle closures beginning at the angle's entrance were more frequently detected. The distance between the iris root and the bottom of the angle varied significantly between groups.

Conclusion:Acute primary angle-closure glaucoma fellow eyes have different topologic features than normotensive narrow-angled eyes, as well as a higher incidence of appositional closure, which may predispose these eyes to an impending acute attack.
