Find the scale factor that was used in the dilation shown.
The scale factor that was used in the dilation could be 1.5 units.
What is scale factor?Suppose a figure (pre image) is dilated (dilated image) by scale factor of k. So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The quantities that are squares or multiple of linear things twice grow by square of scale factor.
So area of first figure = k² × area of second figure
Similarly,
The Volume of first figure = k³ × volume of second figure.
Since the scaling is done by product of some constant, that constant is called scale factor.
Then we have:
K = 4/6
K = 2/3
K = 1.5 units.
Thus, scale factor is the ratio of the new measurement to the old measurement therefore, the scale factor that was used in the dilation could be 1.5 units.

Sample question:
Aimee bought 2 CDs each costing $11.95 and 3 CDs each costing $6.48. She paid with a $50 note. How much change did she receive?
Answer:
2 × 11.95 = 23.9
3 × 6.48 = 19.44
Total spent = 23.9 + 19.44 = 43.34
Change = 50 - 43.34 = $6.66

Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x
The solution is Option A.
The equation which has a constant of proportionality k = 7 is 4y = 28x
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the equation be represented as A
Now , the value of A is
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
Now , the equation is
4y = 28x
On simplifying the equation , we get
Divide by 4 on both sides of the equation , we get
y = 28x/4
y = 7x
y = 7x is of the form y = kx where the value of k is 7
Therefore, the value of k is 7
Hence , the value of proportionality constant is 7
