The value of q for the given relation will be 32.
What is direct variation?
A sort of proportionality known as "direct variation" occurs when one quantity immediately changes in response to a change in another variable.
This suggests that if one number increases, the other quantity will also rise proportionately. Similar to the last example, if one quantity declines, the other amount likewise declines. The link between direct variation and the graph will be linear, resulting in a straight line.
As q varies jointly with v and s,
It implies that
q = k v s
Given,
q=24 when v=2 and s=3
24 = k × 2 × 3
k = 24 / 2 × 3
k = 4
When we put v = 4 and s = 2
⇒ q = 4 × v × s
⇒ q = 4 × 4 × 2
⇒ q = 32

What are rational and irrational numbers?Rational numbers are numbers that can be represented by fractions, such as numbers that have no decimal parts, or numbers in which the decimal parts are terminating or repeating.Irrational numbers are numbers that cannot be represented by fractions, being non-terminating and non-repeating decimals, such as non-exact square roots.To order numbers on the number line, we have that:
For negative numbers, the smaller the integer part is, the greater is the number, for example -2 > -3.For positive numbers, the greater the integer part is, the greater is the number, for example 3 > 2.If the integer parts are equal, we look at the decimal part, following the same logic as above.
For this problem, the numbers are given as follows:
Cube root of 51 = 3.71.4 and 2/3 = 4.67.-π = -3.11415...-17/5 = -3.4.Hence the ordering of the rational and irrational numbers from greatest to least is given by:

This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. how many phone calls should she expect after a week?
From the given equation y = 30(0.92)d, she should expect 193 phone calls after a week.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "="..
If the number of phone calls she should expect can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days, then we can calculate the expected amount phone calls after a week.
To determine how much phone calls she should expect after a week, substitute the value of d.
y = 30(0.92)d
where d = 1 week = 7 days
y = 30(0.92)(7)
y = 193.2

Using algebra, The product of two consecutive numbers is 18 more then 8 times a number
What is Algebra ?Roughly speaking, algebra is the study of mathematical symbols and the rules for manipulating these symbols in formulas; it is a unifying thread of almost all of mathematics
The two consecutive numbers are :
x and x+1
x(x+1) = 8(x+1) + 18
x^2 + x = 8x + 8 + 18
x^2 + x = 8x + 26
x^2 + x - 8x - 26 = 0
x^2 - 7x - 26 = 0
Substitute a=1,b=−7 and c=−26 into the quadratic formula

Determine the slope of the line that contains the given points.
C(3,1), D(-2,1)
The slope of the line containing (3,1) and (-2,1) is Zero(0).
The slope of a straight line can be written as follows,
m = [tex](y_{2} - y_{1} )/(x_{2} - x_{1} )[/tex] equation1
The line is containing the points (-3,3) and (4,3). So, we can write
[tex]y_{2}[/tex] = 1 , [tex]y_{1}[/tex] = 1 , [tex]x_{2}[/tex] = -2 , and [tex]x_{1}[/tex] = 3 .
On substituting the values of variables in equation1, we will get
m = ( (1)-(1) ) / ( (-2)-(3) ) = (0/(-5)) = 0.
As the slope of a line is Zero(0), so we can conclude that the given line is a straight line.
Here:
m = the slope of the line
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) are the first coordinates.
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )are the second coordinates.

2. Amirah, Huixian and Priya make a total of 1530 toys in the ratio 12: 16:17.
(ii) the amount of money Priya earns if she is paid $1.65 for each toy.
Answer:
$953.70
Step-by-step explanation:
sum the parts of the ratio, 12 + 16 + 17 = 45 parts
divide the total number of toys by 45 to find the value of one part of the ratio.
1530 ÷ 45 = 34 , then
Priya makes 17 × 34 = 578 toys
she is paid $1.65 per toy, so is paid
578 × $1.65 = $953.70

Suppose f(x)=2 x-5 and g(x)=|-3 x-1| Find the value. g(2)-f(0)
g(2)- f(0) = 12
Given:
f(x)=2 x- 5
g(x)=|-3 x-1|

A circle is a curve sketched out by a point moving in a plane. The radius, diameter, and circumference of the circle are 11.4 ft, 22.8 ft, and 71.6283 ft, respectively.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that radius of the circle is 11 2/5 ft. Therefore, the radius of the circle in a simplified way can be written as,
The radius of the circle = 11 2/5 ft
= (11×5 + 2)/5 ft
= (55 + 2)/5 ft
= 57/5 ft
Now, the diameter and the circumference of the circle can be written as,
Diameter of circle = 2 × (Radius of the circle)
= 2 × 57/5 ft
= 114/5 ft
Circumference of circle = 2 × π × (Radius of the circle)
= 2 × π × 57/5 ft
= (114/5)π ft
Hence, the radius, diameter, and circumference of the circle are 57/5 ft, 114/5 ft, and (114/5)π ft, respectively.

-4² = - (4 × 4)
This is so because the square was only assigned to 4 and not the negative sign
(-4)² = - 4 × - 4
This is so because the square was assigned to both the negative sign and 4
4² = 4 × 4
This is so because the square was assigned to 4

An archer aims at a target that is 122 centimeters in diameter with 10 concentric circles whose diameters decrease by 12.2 centimeters as they get closer to the center. Find the probability that the archer will hit the center.
The probability that the archer will hit the center which is 122 centimeters in diameter with 10 concentric circles whose diameters decrease by 12.2 centimeters as they get closer to the center is 1/100.
As given in the question,
Total number of concentric circle=10
Outer circle diameter=122centimeters
Diameter decrease by 12.2 centimeters as they get closer to the center
Diameter of inner most circle= 122-9(12.2)
= 12.2centimeter
Probability that archer hit the center
= (Area of inner most circle)/ (Area of target)
= π(6.1)²/π(61)²
= {π(61)²/π(61)²}× 1/100
= 1/100
Therefore, probability that the archer will hit the center is 1/100.

Why is the slope of a vertical line undefined.
The slope of a line can be positive, negative, zero, or undefined. The horizontal line does not rise vertically (y1 − y2 = 0), so the slope is zero, but the vertical line does not extend horizontally (that is, x1 − x2 = 0), so the slope is undefined. As mentioned above, the horizontal line has zero slopes. This does not mean that the horizon has no slope. Since the horizontal line is m=0, it is represented symbolically by the expression y=b. Functions defined by horizontal lines are often called constant functions. The slope of the vertical line is undefined. Any two points on the vertical line have the same x-coordinate, so the gradient cannot be computed as a finite number according to the equation
M=(y2-y1)/(x2-x1)
This is because division by zero is an undefined operation.

⇒ (3/4)y=15 x
⇒ y = 15x/(3/4)
⇒ y = 20x
How to solve an equation?To solve Linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
