1.5 in. × 1.75 in.
Answers
1.25 x 1.75
(20/16) x (28/ 16)
The required blueprint dimensions of a room are given as 1.25 in. × 1.75 in. Option C is correct.
As mentioned in the question,
The scale factor of 1 inch = 16 feet, dimensions of a room that is 20 feet * 28 feet.
Dimensions of a room on a blueprint is to be determined.
The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
1 inch = 16 feet
1 feet = 1/16 inch,
Now,
Scaled dimensions,
= 20 (1/16) inch × 28 (1/16) inch
= 1.25 in × 1.75 in
Thus, The required blueprint dimensions of a room are given as 1.25 in. × 1.75 in. Option C is correct.

Answers
In the triangle LMN angle N is 76 degree.
Given,
In the question:
There is two isosceles triangle in the figure:
Triangle JKL and Triangle LMN
Angle J = 64 degree
To find the angle Angle N
Now, According to the question:
The triangle is isosceles.
<J = 64 degrees
All triangles have 180
<JLK = 180 - 64 - 64
Angle JLK = 52degree.
Angle JLK = MLN = 52 degree (Vertical opposite angle )
M is the left over from the 2 equal angles.
N = 180 - <M - < MLN
N = 180 - 52 - 52
N = 76 degree
Hence, In the triangle LMN angle N is 76 degree.

Answers
Answer:
x = \(\frac{5}{8}\)
Step-by-step explanation:
Given
- 4(3 + x) + 5 = 4(x + 3) ← distribute parenthesis on both sides
- 12 - 4x + 5 = 4x + 12 , that is
17 - 4x = 4x + 12 ( subtract 4x from both sides )
17 - 8x = 12 ( subtract 17 from both sides )
- 8x = - 5 ( divide both sides by - 8 )
x = \(\frac{-5}{-8}\) = \(\frac{5}{8}\)

Find slope:-
m = rise/run = (16-8)/(8-4) = 8/4 = 2

y = mx + b

so, b = 0
So,
y = mx + b
or, h = 2a + 0
so, h = 2a
hence,a = h/2.
The sea sponges's height grows 2cm every 1 year, so you can write an equation to find the height at any age \(a = \frac{h}{2}\)

Answers
This means we are considering only a part of the ellipse that is centered at the point (0,0) and moves in the direction of the hands of a clock.
The given question is asking about a portion of an ellipse centered at the origin and oriented clockwise. Let's break down the question and provide a clear and concise answer.
An ellipse is a curved shape that looks like a stretched-out circle. It has two main properties:
a major axis and a minor axis. The major axis is the longer distance across the ellipse, and the minor axis is the shorter distance.
In the given question, we are specifically talking about a portion of the ellipse. This means we are considering only a part of the entire ellipse.
When we say the portion is centered at the origin, it means that the center of the portion lies at the point (0,0) on the coordinate plane.
Now, let's talk about the orientation. Clockwise orientation means that if you were to walk along the portion of the ellipse, you would move in the direction of the hands of a clock.
To summarize, the given question is asking about a portion of an ellipse centered at the origin and oriented clockwise.

Answers
The statement "x ∈ {x}" is true. The statement "{x} ⊆ {x}" is true. The statement "{x} ∈ {x}" is false. The statement "{x} ∈ {{x}}" is true.
a) The statement is true because an element x can be a member of a set that contains only itself. In this case, the set {x} contains the element x.
b) The statement is true because every element in {x} is also in {x}. Since both sets are identical, {x} is a subset of itself.
c) The statement is false because a set cannot be an element of itself. In this case, {x} is a set, and it cannot be an element of the same set.
d) The statement is true because the set {{x}} contains the set {x} as its only element. Therefore, {x} is an element of the set {{x}}.

Lee just bought a house with open land in the backyard to create a rectangular garden.
He has 46 linear feet of fencing and wants to create a garden with the largest possible
area to plan vegetables and herbs. If he makes the length of the garden 13 feet, the
garden will have an area of 130 square feet. If he makes the length of the garden 11.5
feet, the garden will have a maximum area of 132.25 feet. The area of the garden, A, in
square feet, is a function of the length, x, in linear feet.
Answers
a) Area of the rectangular garden A can be represented by the equation
A = f ( x ) = x ( 23 - x )
where x is the length of the rectangular fencing in feet
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the total length of the linear feet on fencing be = 46 feet
Now , Let the length of the rectangular fencing be = L
The width of the rectangular fencing be = W
So , the area of the rectangular fencing = Length x Width
Area of Rectangular fencing = L x W
And ,
when the length of the garden = 13 feet
Area of garden = 130 feet²
So , width of garden = Area of garden / length of garden
= 130 / 13
= 10 feet
And ,
when the length of the garden = 11.5 feet
Area of garden = 132.25 feet²
So , width of garden = Area of garden / length of garden
= 132.25 / 11.5
= 11.5 feet
So , the total length of the rectangular fencing = 46 feet
Perimeter of fencing = 46 feet
Perimeter P = 2 ( length + width )
= 2 x 23
= 46 feet
So , the equation to find the area of garden A = f ( x ) = x ( P/2 - x )
where P is the perimeter of the rectangular garden
Hence , Area of the rectangular garden A can be represented by the equation A = f ( x ) = x ( 23 - x )
where x is the length of the rectangular fencing in feet

Dear student, please answer the following questions: First Question ( 15 marks): The inside design conditions for a textile factory are \( 24 \% \) db and Rhinside \( =78 \% \) relative humidity. The
Answers
Proper ventilation, humidity control, and temperature regulation systems are typically employed to maintain these design conditions.
The inside design conditions for a textile factory are given as follows:
- Dry-bulb temperature (T_{text{db, inside})(24%) db (degrees Celsius)
- Relative humidity (RH_{text{inside}} \)): (78 %) relative humidity
These conditions describe the desired environmental parameters inside the textile factory. It is important to maintain these conditions to ensure optimal working conditions for the production of textiles.
The dry-bulb temperature (T_{text{db}) refers to the air temperature as measured by a standard thermometer without accounting for moisture content.
In this case, the inside design condition specifies a dry-bulb temperature of (24 %) db.
The relative humidity ( RH) represents the amount of moisture present in the air relative to the maximum amount of moisture the air can hold at a specific temperature.
A relative humidity of ( 78 %) indicates that the air inside the textile factory is holding 78 percent of the maximum amount of moisture it can hold at the given temperature.
These design conditions are crucial for maintaining the appropriate moisture levels and temperature inside the textile factory, which can impact the quality of textile production, comfort of workers, and overall efficiency of the manufacturing process.
Proper ventilation, humidity control, and temperature regulation systems are typically employed to maintain these design conditions.

How to solve
-y - 10=6x
5x + y= -10
Using the system by elimination
Answers
-y - 10 = 6x
5x + y = -10
First, we can add or subtract the equations in such a way that one variable is eliminated.
Add the equations :
-y - 10 + 5x + y = 6x + -10
5x = -20
x = -4
now we have x = -4 we can substitute this value in any of the equations we have.
let's substitute x = -4 in the first equation
-y -10 = 6*(-4)
-y = -40
y = 40
we have x = -4 and y = 40
we could check the solution by substitute x = -4 and y = 40 in the second equation
5*(-4) + 40 = -10
and we get 20+40 = -10, which is true.
therefore the solution for the system of equations is x = -4, y = 40
