The inequality to find the value of x for the rectangle is 2(2x+4) < 122 and the value of x should be less than 28.5.

According to the question,

We have the following information:

The perimeter of the rectangle is less than 122.

A rectangle has a width of x and a length of x plus 4.

Now, the expressions for the width and length of the rectangle are given below:

Width = x units

Length = (x+4) units

We know that the following formula is used to find the perimeter of rectangle:

2(length+width) < 122

2(x+4+x) < 122

2(2x+4) < 122

Dividing by 2 on both sides:

2x+4 < 122/2

2x+4 < 61

Subtracting 4 from both sides:

2x < 61-4

2x < 57

Dividing by 2 on both sides:

x < 57/2

x < 28.6

Hence, the inequality to find the value of x for the rectangle is 2(2x+4) < 122 and the value of x should be less than 28.5.

The rate of change of the temperature on the time interval is -2°C. This means that, in average, for each hour that passes the temperature decreases by 2 degrees Celcius.

A rate of change is defined as the quotient between the difference in some measure (in this case it will be the difference between the final temperature and the initial temperature) and the time interval in which it happens.

Here we know that:

final temperature = -5°C

Initial temperature = 13°C

And this change goes from 3 P.M. to midnight, so the change happens on an interval of 9 hours.

Then the rate of change of the temperature is:

r = (-5°C - 13°C)/9h = -2°C/h

So for each hour, the temperature decreases by 2°C.

Linda' number of questions has an expected value of 11.3

The given parameters in the question are:

8 questions with probability 0.6,

15 questions with probability 0.3

20 questions with probability 0.1

The expected value is then calculated as

E(x) = Sum of (number of questions * probability)

Substitute the known values in the above equation, so, we have the following representation

E(x) = 8 * 0.6 + 15 * 0.3 + 20 * 0.1

Evaluate

E(x) = 11.3

Answer:

I believe the answer is C

Step-by-step explanation:

The coordinates of B are (-7,-2).

What do you mean by x and y coordinates?

The x and y coordinates are a component of the x-axis and y-axis in a 2D space in the Cartesian coordinate system. The x and y coordinates for a point in space are expressed as an ordered pair (x, y). The position of the point on the x-axis is shown by the first number, while its location on the y-axis is indicated by the second number.

According to the given data in the question,

if M is the location where line segment AB meets its midpoint.

Then, we will using the midpoint formula,

[tex](-5,2)=(\frac{-3+x}{2},\frac{6+y}{2})..............(1)[/tex]

Putting the x-coordinates in (1),

[tex]-5=\frac{-3+x}{2}\\ -10=-3+x\\-10+3=x\\x=-7[/tex]

Similarly, putting the y-coordinates in (1),

[tex]2=\frac{6+y}{2} \\4=6+y\\4-6=y\\y=-2[/tex]

Hence, the coordinates of B are (-7,-2).

The probability of selecting two cards that are not orange, is 0.483 and the probability of selecting two cards that are not red and green, is 0.393.

In the given question we have to find the probability.

From the question it is given that,

10 yellow, 6 green, 9 orange, and 5 red cards facedown.

Total number of cards = 10+6+9+5

Total number of cards = 30

Once a card selected, NOT replaced.

a.) Now finding the probability of selecting two cards that are not orange.

There are total orange cards = 9

The number of cards except orange card = 21

Then the probability of selecting one card except orange = 21/30

Then the probability of selecting other card except orange = 20/29

Then the probability of selecting two cards that are not orange is

P(O) = 21/30 * 20/29

P(O) = 420/870

P(O) = 0.483

Then the probability of selecting two cards that are not orange, is 0.483.

(b) Now finding the probability of selecting two cards that are neither red nor green.

The total number of cards except red and green card = 19

Then the probability of selecting one card except red and green card = 19/30

Then the probability of selecting other card except red and green card = 18/29

Then the probability of selecting two cards that are not red and green card is

P(RG) = 19/30 * 18/29

P(RG) = 342/870

P(RG) = 0.393

Then the probability of selecting two cards that are not red and green, is 0.393.

If the plumber charges a customer $45 , then the visit was 0.5 hours long .

In the question ,

it is given that

the fixed charge to visit a client's home is = $35

additional per hour charge of plumber is = $20 .

let the time taken by plumber in the customer house be "x" .

So , according to the question

the equation for total charge is

total charge = 35 + 20x

given the customer paid $45 ,

So , 45 = 35 + 20x

20x = 45 - 35

20x = 10

x = 10/20 = 0.5

Therefore , If the plumber charges a customer $45 , then the visit was 0.5 hours long .

1. The Cost of Ending Inventory and the Cost of Goods Sold under LIFO, FIFO, and Weighted-Average, are as follows:

                                      LIFO           FIFO      Weighted-Average

Ending inventory          $425          $691                $573

Cost of goods sold      $492          $226               $344

FIFO (First-in, First-out) assumes that the physical flow of goods sold follows the chronological order of acquisition.

LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.

The weighted-average method uses the average cost of goods to compute the ending inventory and the cost of goods sold.

LIFO:

Ending inventory = $425 ($917 - $492)

Cost of goods sold = $492 (12 x $20 + 12 x $21)

FIFO:

Ending inventory = $691 (9 x $11 + 17 x $20 + 12 x $21)

Cost of goods sold = $226 ($917 - $691)

Weighted Average:

Ending inventory = $573 (40 x $14.33)

Cost of goods sold = $344 (24 x $14.33)

                                   Units  Unit Cost    Total Cost

Jan. 1      Beg. Inventory  20     $8.00           $160

May 10   Purchases          15     $11.00           $165

June 30 Purchases          17    $20.00         $340

Answer:

Step-by-step explanation:

8.5 inches divided by 2 = 4.25 inches which is the base of the triangle with a height of 5.8 inches. Area of that triangle is 1/2 x base x height = 1/2 x 4.25 inches x 5.8 inches = 12.325 inches squared. Two of the triangles make 1 full isoceles triangle= 2 x 12.325 inches squared = 24.65 inces squared. But there are 5 isoceles triangles in a pentagon, so 5 times 24.65 inches squared = 123.25 inches squared.
