Proportional reasoning is a form of 'operational reasoning' based on
Piaget's theory.
Proportional reasoning can be used to solve a problem; B. When one
quantity is a constant multiple of the other.
Reasons:
Proportional reasoning is the reasoning based on the cognition that a
relationship exists between the multiples of the variables in the problem,
such that the magnitude of a variable can implied from the changes made
to the relationships connecting the variables.
An example of proportional reasoning is the distance travelled, d, after a
given time, t, at a constant velocity, v;
d = v·tTo judge the distance travelled, a constant, v, multiplies the time, t, such
that, at a longer time, it can be reasoned that the distance travelled is
much further.
Therefore;
Proportional reasoning can be used to solve a problem in which one quantity is a constant multiple of the other.Learn more here:

Options B and C are the correct conditions under which you can use proportional reasoning to solve a problem:
Proportional reasoning is a mathematical concept that involves understanding and solving problems that relate two or more quantities in a proportional manner. It helps us analyze and predict how changes in one quantity affect another based on their proportional relationship.
B: When one quantity is a constant multiple of the other:
In this case, if one quantity is a constant multiple of another, it means that they are directly proportional. For example, if the quantity of oranges you buy is always twice the quantity of apples you buy, then the quantities of oranges and apples are directly proportional. Proportional reasoning can be used to solve problems related to this relationship.
C: When the two quantities multiplied equal a constant:
If the product of two quantities remains constant, regardless of their individual values, they are inversely proportional. For instance, if the time taken to complete a task is inversely proportional to the number of people working on it, as the number of people increases, the time taken decreases. Proportional reasoning can be used to solve problems involving inverse proportionality.
In summary, proportional reasoning is used when two quantities are directly or inversely proportional to each other, i.e., when one quantity is a constant multiple of the other or when the product of the two quantities remains constant.

Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan? USE NUMBERS ONLY.
Answer: 60 feets
Step-by-step explanation:
Given the question :
Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan?
Using a scale factor of 1 inch : 12 feet
Wingspan of plastic toy bird = 5 inches
Calculate the actual bird wingspan
(1 inch / 12 feet) = (toy bird wingspan / actual bird wingspan)
( 1 inch / 12 feet) = (5 / actual bird wingspan)
Actual bird wingspan = 5 × 12
Actual bird wingspan = 60 feets

|4x + 4| = 15
First, let's get rid of the absolute value signs to get the first solution.
4x + 4 = 15
Subtract 4 from both sides
4x = 11
Divide each side by 4
x = 11/4 or 2.75
Now, let's get the solution by changing 15 to -15.
4x + 4 = -15
Subtract 4 from both sides
4x = -19
Divide both sides by 4
x = -19/4 or -4.75
Simplify. 4−8÷2+3

help me find b and c
Answer:
b = 48 °, c = 46°
Step-by-step explanation:
c = 46 ° as between parallel lines, alternate opposite angles are equal.
since opposite angles are equal 94 ° = 46 ° + additional angel
therefore b = 94° - 46 ° = 48 ° , as sum of 2 internal angles of a triangle is equal to opposite exterior angle.

Find the mid point
Answer:
The answer is
( 4 , - 1)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(2,-4) and (6,2)
The midpoint is
[tex]M = ( \frac{2 + 6}{ 2} , \: \frac{ - 4 + 2}{2} ) \\ = ( \frac{8}{2} \: , \: - \frac{2}{2} )[/tex]
We have the final answer as
( 4 , - 1)Hope this helps you
Answer:
The mid point must be (4,-1)
Step-by-step explanation:
mid point= [(X1+X2)/2 , (Y1+Y2)/2]
