One number is six less than three times another number. If the sum of the numbers is 38, find the numbers.
Answer: Let's call the first number "x" and the second number "y".
From the problem statement, we know that:
x = 3y - 6 (because one number is six less than three times the other number)
x + y = 38 (because the sum of the numbers is 38)
We can substitute the first equation into the second equation to solve for one of the variables:
3y - 6 + y = 38
4y - 6 = 38
4y = 44
y = 11
Now we can substitute this value of y back into the first equation to find the value of x:
x = 3(11) - 6
x = 29
So the two numbers are:
x = 29
y = 11

Circle E has a radius of 5.3 meters. FG is a chord and HE is a perpendicular bisector of FG. If FG = 6.5 meters, calculate the distance of EH.
The distance of EH is 4.1866 meters.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
From the question, we have,
Radius of the circle = 5.3 meters
EF = EI = 5.3 meters
FG = 6.5 meters
Also, we have, HE is a perpendicular bisector of FG.
FH = HG = 6.5 / 2 = 3.25
We have to calculate EH.
We have, FH is the projection of EF in the vertical axis.
FH = EF sin (θ), where θ is the angle FEH.
3.25 = 5.3 sin (θ)
sin (θ) = 0.6132
θ = sin⁻¹ (0.6132)
θ = 37.82°
We have, EH is the projection of EF into the horizontal axis.
EH = EF cos (θ)
= 5.3 cos (37.82°)
= 5.3 × 0.7899
= 4.1866 meters
Hence the length of EH is 4.1866 meters.

How many cords of wood could you fit in a room that is 4 yards long 4 yards wide and two yards High answer to the nearest hundredth
Answer: To find the number of cords of wood that can fit in a room, we need to find the volume of the room and then divide that by the volume of a cord of wood.
A cord of wood is a unit of measurement that is equal to 128 cubic feet.
The volume of the room can be found by multiplying the length by the width by the height:
V = 4 x 4 x 2 = 32 cubic yards
To convert cubic yards to cubic feet, we can use the conversion factor of 1 cubic yard = 27 cubic feet.
So, the volume of the room in cubic feet is:
V = 32 x 27 = 864 cubic feet
To find the number of cords of wood that can fit in the room, we divide the volume of the room by the volume of a cord of wood:
cords = 864 / 128
cords ≈ 6.75
So, you could fit approximately 6.75 cords of wood in a room that is 4 yards long, 4 yards wide, and 2 yards high, to the nearest hundredth.

How to determine the measure of the anglesAs a general rule:
Complementary angles add up to 90 degrees
This means that

3x + 6 + 4x - 14 = 90 ------ Substituting 3x + 6 and 4x - 14 for ∡s ABC and CBD
Evaluate the like terms
7x = 98
Divide both sides by 7

graph the equation y=2/3x-1 iready quiz graph linear equations
Answer: To graph the equation y = 2/3x - 1, we can start by finding some points that satisfy the equation.
We can pick any value for x and substitute it into the equation to find the corresponding y-value.
For example:
When x = 0, y = (2/3)(0) - 1 = -1
When x = 1, y = (2/3)(1) - 1 = -1/3
When x = 2, y = (2/3)(2) - 1 = 1/3
When x = 3, y = (2/3)(3) - 1 = 2/3
We can plot these points on a coordinate plane and then connect them with a straight line to graph the equation.
The graph will be a line that passes through the points (0, -1), (1, -1/3), (2, 1/3), and (3, 2/3).

The values of the variables namely x, y and z of the given triangle are;
x = 12, y = 9√13, z = 6√13
How to use Pythagoras Theorem?There are three sides of a right angle triangle namely; Opposite, Adjacent and Hypotenuse.
The formula for Pythagoras theorem is;
Hypotenuse² = Opposite² + Adjacent²
Thus;
y² = 27² + 18²
y = √(27² + 18²)
y = √1053
y = 9√13
Using concept of similar triangles, we can say that;
x/18 = 18/27
x = (18 * 18)/27
x = 12
Using Pythagoras theorem again;
z = √(12² + 18²)
z = √468
z = 6√13

What is the perimeter of triangle “QTS”
Answer: 15 + x, or x + 15
Step-by-step explanation:
The perimeter of triangle QTS is represented as line segments QT + TS + QS. This means:
6 + 6 + ((3x - 1) + (4 - 2x))
You can first simplify 6 + 6, 6 + 6 = 12
12 + ((3x - 1) + (4 - 2x))
Next, focus on ((3x - 1) + (4 - 2x))
3x + (-1) + 4 + (-2x), addition is commutative, so use addition
3x + (-2x) + 4 + (-1)
(3x - 2x) + (4 - 1)
x + (4 - 1)
x + 3
The equation is now:
12 + x + 3
You can simplify this more by adding 12 + 3
15 + x
The answer is 15 + x or x + 15 because that is as simplified as the equation can be.

A situation in which solutions exist so that both parties are trying to find a mutually acceptable solution to a complex conflict is known as which of the following?
A) mutual gains
B) win-lose
C) zero-sum
D) win-win
E) None of the above.
D) Win-win is a situation in which both parties come away with a positive outcome.
Win-win is a situation in which both parties come away with a positive outcome. It is the ideal solution to a complex conflict, as it ensures that both parties benefit in some way. Win-win solutions involve a collaborative approach to problem solving, where each party works together to find a mutually beneficial solution. This can involve compromise, trade-offs, and creative negotiation.
For example, two companies may be in competition for the same contract. Rather than viewing each other as adversaries, they could work together to create a win-win solution that meets their respective needs. This could involve a collaborative approach to the project, or a mutually beneficial pricing arrangement.
Win-win solutions also require an understanding of each party's needs, interests, and values. It is important to identify the underlying interests that each party has, and use them to create a solution that meets everyone's needs. By taking the time to understand each other's perspectives, it is possible to create a solution that is beneficial to both parties. In this way, win-win solutions provide an opportunity to develop a constructive relationship that can be beneficial in the long term.

The new computer will take to loading a document with 2 graphics and 1 paragraph is 43.99 seconds.
How to calculate time taken using percentage?Time taken can be calculated using percentages by determining the percentage of time that has already passed, then calculating the remaining time based on the percentage of time remaining.
For example, if you are asked to calculate the time taken for a project that is 50% complete, you would first need to determine the total length of the project. Let's say it is a project with a timeline of two months.
Next, you would need to calculate the percentage of time that has already passed. In this case, since the project is 50% complete, 50% of the two months has already passed. This means that one month has passed.
Finally, you can determine the time taken by subtracting the time that has already passed from the total length of the project. In this case, the time taken would be one month, since one month has already passed and there is one month remaining until the project is completed.
The old computer would load 2 graphs and one paragraph in:
22 × 2 seconds + 9 seconds = 53 seconds
The new computer is 17% faster so:
53 - (17% × 53) = 43.99 seconds

What are the 2D shapes?The plane forms that can be sketched on a flat (or plane) surface or a piece of paper are known as 2D shapes. Every 2D shape has different attributes, like area and perimeter. Some of the two-dimensional objects have sides and corners, while others have curved edges.
Given two pathways,
circular and square, and the circular pathway is inscribed inside of a square pathway,
area of circular pathway = 768 square feet
area of circle = π/4*d²
where d is the diameter
768 = π/4*d²
768*4 = πd² (π = 3)
3072/3 = d²
d = √1024
d = 32 feet
since the circle is inscribed in a square the length of a side of square is equal to the diameter of the circle,
d = a = 32 feet
to find the perimeter of the square path,
perimeter of square = 4a
perimeter of square = 4*32
perimeter of square = 128 feet

Explain weather there is a possible transformation of f in the form g(x) =f(x)+k, where k is a constant for which the graph y=g(x) will have no x-intercepts. Enter your answer and your justification in the space provided.
Answer:
Yes, a transformation of f in the form g(x) =f(x)+k can have no x-intercepts. This will occur if the constant k is added to the y-value of every point on the f(x) graph, resulting in the chart of g(x) being shifted upward by k units. If the original diagram of f(x) had no x-intercepts, then the graph of g(x) would also have no x-intercepts because the x-coordinate of each point on the graph of f(x) is unchanged by the transformation.
