The length of the rectangular classroom will be 8 inches on the scale drawing.

What is a rectangle defined as?

Rectangles are four-sided polygons having internal angles of 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from the square in that its opposite sides are of equal length.

If one side of a rectangle is 20 cm long, the other side must be 20 cm long as well.

Two diagonals cross form a rectangle. Both diagonals are the same length.

P = 2 (Length + Width) defines the perimeter.

Rectangle Area=Length*Breadth

Now,

As total length of room =36 feet

and 9 feet = 2 inch on drawing scale

then length of classroom on  drawing scale is = 36/9*2

=8 inch

Hence,

            The length of the rectangular classroom will be 8 inches on the scale drawing.

Step-by-step explanation:

The simplest radical form is x⁵.

Radical form is the expression that involves radical signs such as square root, cube root, etc instead of using exponents to describe the same entity.

The given radical form is [tex]\frac{x^{\frac{5}{6} }}{x^{\frac{1}{6} }}[/tex].

The radical and root of a number are the same thing.

Simplifying a radical eliminates the square roots, cube roots, fourth roots, etc.

In the given expression, 1/6 is the 6th root, in both numerator and denominator cancel out 6th root x.

That is,  [tex]\frac{x^{\frac{5}{6} }}{x^{\frac{1}{6} }}[/tex] =x⁵ ([tex]x^{\frac{1}{6} }[/tex]  in the denominator is gets cancelled with [tex]x^{\frac{1}{6} }[/tex] in the numerator)

< 1 is acute (less than 90⁰)

<2 is acute

<BOA is obtuse (greater than 90⁰)

The unknown sides of the figure are

< KNL = 89.85 degrees

< KJL = 50 degrees

< JKM = 40 degrees

< JML = 80 degrees

A rhombus has it's interior angles equal to 360 degrees and the opposites and angels are equal

hence angle MLK = MJK = 100 degrees

< JML = < JKL = say x

2x + 2(100) = 360

2x = 360 - 200

2x = 160

x = 80

< MJL + < KJL = MJK adjacent angles

50 + < KJL = 100

< KJL = 50 degrees

The sides of a rhombus are equal

JM = KL =  15.6

ML = JK = 15.6

Given that NK = 12 and NL = 10, using cosine rule we solve for < KNL

cos < KNL = (15.6² - 12² - 10²) / -2 * 12 * 10

cos < KNL = 1/375

< KNL = arc cos (1/375)

< KNL = 89.85

< JKM + < JKL +  <JNK = 180 sum of angles on a triangle

<JNK = 180 - 89.85 = 90.15

< JKM + 50 + 90.15 = 180

< JKM = 180 - 50 - 90.15

< JKM = 39.85 approximately 40

Similar triangles are triangles in which the ratio of their sides are equal.

Given the similar triangles, ΔMNP and ΔMAB

By the ratio of similar triangles, we have that

MP/MN = MB/MA

We observe that MN = MA + AN

So, MA = MN - AN

Step-by-step explanation:

Answer:

since y = 0 when x = 0

Step-by-step explanation:

We can start by solving for y in the equation:

y * x = 3/5 y

Dividing both sides by y:

x = 3/5

So the equation y * x = 3/5 y can be simplified to:

y = 5/3 x

This equation shows that there is a proportional relationship between y and x, where y is always equal to 5/3 times x. This relationship can be represented on a graph by plotting points (x, y) and drawing a line through them. The slope of the line will be 5/3, and the y-intercept will be 0, since y = 0 when x = 0.

Answer:

y = ±1/√5

Step-by-step explanation:

3y = 3/5y

⇒3y×5y = 3

⇒15y² = 3

⇒y² = 3/15

⇒y² = 1/5

⇒y = ±1/√5

The solution of the equation 16g + 3 = 4 - 13g is g = 1/29

An equation is a statement that two expressions are equal. In other words, it's a mathematical sentence that says that the value on the left side of the equation is equal to the value on the right side.

In your problem, you have the equation:

16g + 3 = 4 - 13g

To solve this equation, the goal is to isolate the variable "g" on one side of the equation, so we can find its value. To do that, we need to use some algebraic techniques.

First, we can simplify the equation by combining like terms. We can add 13g to both sides of the equation to get:

16g + 13g + 3 = 4

Now we can combine the like terms on the left side of the equation:

29g + 3 = 4

Next, we want to isolate the variable "g" on one side of the equation. To do that, we can subtract 3 from both sides of the equation:

29g = 1

Finally, we can solve for "g" by dividing both sides of the equation by 29:

g = 1/29

So the solution to the equation is g = 1/29.

The angle of rotation that will bring Car 3 to the position of Car 18 is 11.25 degrees. The angle of rotation that a car travels when it moves one position counterclockwise is 168.75 degrees. Car 3 needs to move 15 positions counterclockwise to reach Car 18.

a. We have to determine the angle of rotation that will bring Car 3 to the position of Car 18 on the London Eye, so we will first calculate the number of positions that Car 3 needs to move counterclockwise to reach Car 18.

We know that there are 32 observation cars on the London Eye, so the distance between two adjacent cars will be 360/32 = 11.25 degrees.

b. To find the angle of rotation that a car travels when it moves one position counterclockwise, we will divide the full rotation of the London Eye by the number of observation cars (i.e. 32).

360/32 = 11.25 degrees

Next, to determine the angle of rotation that would bring Car 3 to the position of Car 18, we will multiply the number of positions that Car 3 needs to move counterclockwise and the angle of rotation for each position as follows -

15 x 11.25 = 168.75 degrees

Therefore, the angle of rotation that a car travels when it moves one position counterclockwise is 168.75 degrees.

c. To find the number of positions that Car 3 needs to move counterclockwise to reach Car 18, we will subtract the position number of Car 18 from that of Car 3 and then take the absolute value, as it is a cyclical rotation.

|18 - 3| = 15

Hence, Car 3 needs to move 15 positions counterclockwise to reach Car 18.

Answer:

# of appointments is 3

Step-by-step explanation:

He makes $75 per appointment, which means this immediate value is directly dependent on the number of appointments (x). So it can be given by 75x.

Tips are simply added, tips are not directly dependent on the number of visits as customers will tip differently so we can add $40 to the equation.

Now we must negate the expenses, each appointment there is a fee of $10. So it can be given as 10x.

We know that this all must equal $235.

So the equation is as follows:

235 = (75x)+40-(10x)

Simplifying we get

235 = 65x + 40

195 = 65x

195/65 = x

x = 3

Therefore, Logan had 3 appointments.

Players A and B withdraw balls from the urn consecutively until a read ball is selected, the probability that player A selects the red ball is approximately 0.408.

To find the probability that player A selects the red ball, we can use the law of total probability and consider all the possible ways the game could end. A selects the red ball on the first draw. The probability of this is simply the proportion of red balls in the urn, which is 3/10.

A selects a black ball on the first draw, followed by B selecting a black ball on their turn, and so on, until A finally selects the red ball. The probability of this is:

(7/10) * (6/9) * (5/8) * ... * (1/4) * (3/7)

Notice that the probability of selecting a black ball decreases by one after each turn, since the total number of balls in the urn decreases by one and the number of black balls decreases by one.

The probability of selecting the red ball on the last turn (after all the black balls have been selected) is 3/3 = 1. We multiply all these probabilities together to get the total probability of this sequence of events.

A selects a black ball on the first draw, followed by B selecting a black ball on their turn, and so on, until B finally selects the red ball. The probability of this is:

(7/10) * (6/9) * (5/8) * ... * (2/4) * (3/6)

Notice that the probability of selecting a black ball decreases by one after each turn, just like in the previous case. However, the probability of B selecting the red ball on their turn is now 3/6, since there are only six balls left in the urn at this point. We multiply all these probabilities together to get the total probability of this sequence of events.

Adding up these three probabilities, we get:

3/10 + (7/10) * (6/9) * (5/8) * ... * (1/4) * (3/7) + (7/10) * (6/9) * (5/8) * ... * (2/4) * (3/6) ≈ 0.408

Casey Na is due an extra overtime pay of $1,170 for the first quarter as part of his company's perfect attendance program.

What is overtime pay?

Overtime pay is the additional compensation paid to an employee for any hours worked in excess of the standard working hours or beyond the standard workweek. The rate of overtime pay is usually higher than the regular rate of pay for an employee's normal working hours.

To determine the extra overtime pay due to Casey Na for the first quarter, we need to know his regular pay rate and the number of hours he worked each week.

Let's assume that Casey Na's regular pay rate is $20 per hour and that he worked 40 hours each week during the first quarter. This means that he worked 3 hours of overtime each week, for a total of 39 hours at his regular rate and 3 hours at his overtime rate.

To calculate his overtime pay for the first quarter, we can use the following formula:

Overtime pay = overtime hours x overtime rate

Since Casey Na worked 3 hours of overtime each week for 13 weeks, his total overtime hours for the first quarter were:

Total overtime hours = 3 hours/week x 13 weeks = 39 hours

His overtime rate is 1.5 times his regular rate, or $20 x 1.5 = $30 per hour.

Therefore, his overtime pay for the first quarter was:

Overtime pay = 39 hours x $30/hour = $1,170

Since he also earned a bonus of $975 for perfect attendance, his total extra pay for the first quarter was:

Extra pay = Overtime pay + Bonus = $1,170 + $975 = $2,145

Therefore, Casey Na is due an extra overtime pay of $1,170 for the first quarter as part of his company's perfect attendance program.

                         [1 1 1]                                    [3]

An example of a 3x3 matrix A and a 3x1 matrix B such that the solution set of Ax = b is a line in R³ that does not contain the origin:

A = [1 2 3]

   [2 4 6]

   [1 1 1]

B = [1]

   [2]

   [3]

To check that the solution set of Ax = b is a line in R³, we can solve for x in terms of a parameter t:

Ax = b

[1 2 3] [x1] = [1]

[2 4 6] [x2]   [2]

[1 1 1] [x3]   [3]

Ax = b

x1 + 2x2 + 3x3 = 1

2x1 + 4x2 + 6x3 = 2

x1 + x2 + x3 = 3

Dividing the second equation by 2 and subtracting it from the first equation, we get:

-x1 - x2 = -1

Solving for x2 in terms of x1 and x3, we get:

x2 = -x1 + 1 - (3/2)x3

Solving for x3 in terms of a parameter t, we get:

x3 = t

Then, x1 can be expressed in terms of t as:

x1 = -t + 1

Therefore, the solution set of Ax = b is:

x = [-t + 1]

   [-t + 1 - (3/2)t]

which is a line passing through the point (1, 1/2, 0) with a direction vector [-1, -3/2, 1].

A × [0; 0; 0] = [0; 0; 0]

Therefore, the origin is not on the line of solutions.
