On a scale drawing, a building has length 12.4 cm and width 9.4 cm. The real length of the building is 62 metres. Work out, in metres, the real width of the building.
The real width of the building is given by 47 meters.
Given that the actual length of the building is 62 meters.
In a scale drawing, the length of the building is 12.4 cm.
So, 12.4 cm = 62 meters
1 cm = 62/12.4 = 620/124 = 5 meters.
Also given that the width of building on scale drawing = 9.4 cm
Hence the real width of the building = 9.4 * 5 = 47 meters.

How does a qualitative graph describe the relationship between quantities? Explain your reasoning.
Qualitative graphs depict the relationship between two quantities without including numerical values.
The benefit is that it only shows the overall trend of the effect. When we experiment with these variables, we can immediately see how the graph will look. This could validate our findings.
A quantitative relationship emerges as one variable influencing another, which can be seen with a graph. Examine how each variable is represented on the graph, as well as how quantitative relationships are stated using equations.
Quantitative data refers to data that's represented by numbers.
This is the result of graphing all of the data points. Look at that, our data points have formed a straight line! We can draw the line in using a ruler to make it more visible. We'll notice that the line passes through all of the points in our data, indicating that there is a definite relationship in our quantitative data.
Thus, qualitative graphs depict the relationship between two quantities without including numerical values.

Function g can be thought of as a translated (shifted) version of f(x) = x^2
The new function's equation is g(x) = (x - 2)² + 6
Given,
The parent function, f(x) = x²
We have to determine the equation for the new function g(x)
Vertical shift:
The parent function is clearly pushed 6 units upward from the graph.
The general formula to increase the c units on the graph is f(x) + c
As a result, by using the rule, the new function g(x)of vertical shift is provided by g(x) = x² + 6
Horizontal shift:
It is clear from the graph that the parent function has been moved 2 units to the right.
To move the graph's c units to the right, follow this basic formula: f(x - c)
Consequently, the new function g(xhorizontal )'s shift is given by g(x) = (x - 2)²
The new function g( x ) is as follows:
The equation results in the new function being shifted 2 units to the right and 6 units upward.
g(x) = (x - 2)² + 6
Therefore, the new function's equation is g(x) = (x - 2)² + 6

The graph of the function f(x)=log5(x) is stretched vertically by a factor of 3, reflected over the x-axis, reflected over the y-axis, and shifted down by 4 units.
Find the equation of the function g(x) described above.
Note: If you are using log you need to type it in and use the subscript button on the keyboard. There is no log button.
The equation of the function g(x), considering the transformations, is given as follows:
[tex]g(x) = -3\log_5{(-x)} - 4[/tex]
How to obtain the equation of function g(x)?The equation of function g(x) is obtained applying the transformations to the parent function f(x).
The parent function f(x) is given as follows:
f(x) = log5(x).
The vertical stretch by a factor of 3 is represented by a multiplication of f(x) by 3, hence:
g(x) = 3log5(x).
The reflection over the x-axis is represented by a multiplication of the function by -1, hence:
g(x) = -3log5(x).
The reflection over the y-axis is represented by a multiplication by -1 inside the domain of the function, hence:
g(x) = -3log5(-x).
The shift down by four units is represented by a subtraction of the function by four, hence:
g(x) = -3log5(-x) - 4.

Solve the system by using elimination:
3x + 6y = 10
2x + 3y = 5
Answer:
(0, [tex]\frac{5}{3}[/tex] )
Step-by-step explanation:
3x + 6y = 10 → (1)
2x + 3y = 5 → (2)
multiplying (2) by - 2 and adding to (1) will eliminate y
- 4x - 6y = - 10 → (3)
add (1) and (3) term by term to eliminate y
- x + 0 = 0
- x = 0
x = 0
substitute x = 0 into either of the 2 equations and solve for x
substituting into (2)
2(0) + 3y = 5
3y = 5 ( divide both sides by 3 )
y = [tex]\frac{5}{3}[/tex]

If she earned a total of $83. 00 for the week, how many hours did laurie work on monday? enter and solve an equation.
If she put in the same amount of time on Wednesday and Monday. She worked 4 hours on Sunday. The amount of hours Laurie will work on Monday if she earns a total of $83.00 for the week will be 3.
Define equation.In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities.
Given,
if she put in the same amount of time on Wednesday and Monday. She worked 4 hours on Sunday. The amount of hours Laurie will work on Monday if she earns a total of $83.00 for the week will be: 3.
$7.5= 1 hour various days
Sunday: $9.50 or ($7.50+$2.00) = 1 hour
Sunday = 4 + $9.50 = 38
Let Monday equal x $7.5 = 7.5x.
Let Wednesday equal x $7.5 equal x.
Let the total income be $83
Let x be the amount of hours.

the function h(x) is a transformation of the square root parent function
f(x)=[tex]\sqrt{x}[/tex]. what function is h(x)
The function h(x) is a translation of 4 units to the left, so the correct options is B.
h(x) = √(x + 4)
What is the rule for function h(x)?We know that h(x) is a transformation on the parent square root function:
f(x) = √x
If we look at the graphs, we can see h(x) is translated 4 units to the left.
Now, for a function f(x), we define a horizontal translation of N units as:
h(x) = f(x + N)
if N < 0, the translation is to the right.
if N > 0, the translation is to the left.
In this case we have a translation of 4 units to the left, then N = 4, so we can write:
h(x)= f(x + 4)
Replacing the function f(x) we get:
h(x) = √(x + 4)
So the correct option is B.

Answer: A number which is divided by 5, with the result as 50 less than if the number had been divided by 6 would be; -1500
How to solve Algebra Word Problems?
Let the number be x. We are asked that it is divided by 5, and the result is 50 less than if the number had been divided by 6;
(x/6) - (x/5) = 50
Multiply by 30 to get;
5x - 6x = 1500
-x = 1500
x = -1500
Let the older turtle be represented x and the younger one be y.
Todays age,
Older turtle = 11y years
Younger turtle = y years
Also the equation form as;
11y + 24 = 7(y + 24)
11y + 24 = 7y + 168
11y - 7y = 168 - 24
4y = 144
y = 144/4
y = 36
Thus;
Age of older turtle today = 396 years
Age of younger turtle today = 36 years
Therefore,

After collision, Car A moves with a velocity of 4.1 m/s
Elastic CollisionAn elastic collision is a collision in which there is no net loss in kinetic energy in the system due to the collision. Both momentum and kinetic energy are conserved in an elastic collision. It can be either one-dimensional or two-dimensional. In the real world, perfectly elastic collision is impossible because there is bound to be some energy conversion, however small. However, though there is no change in the linear momentum of the whole system, there is a change in the individual momenta of the involved components, which are equal and opposite in magnitude and cancel each other out and the initial energy is conserved.
The formula of elastic collision is given as
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
Assuming after collision, car B has a velocity of 0m/s
281(2.82) + 209(1.72) = 281 * v + 0
792.42 + 359.48 = 281v

A triangle has two sides of length 12 and 18. What is the smallest possible whole-number length for the third side?
Answer:
7
Step-by-step explanation:
You want the integer length of the shortest third side that will form a triangle with sides 12 and 18.
Triangle inequalityThe triangle inequality requires the sum of any two sides exceed the measure of the third side. If x is the short side, we want ...
x +12 > 18
x > 6 . . . . . . subtract 12
The smallest integer greater than 6 is 7.
The third side must be at least 7 units long.
__
Additional comment
Some authors write the triangle inequality as a+b≥c. If you use that version, then the shortest side can be 6 units. The resulting "triangle" will have zero area, and will look like a line segment 18 units long.
