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

Step-by-step explanation:
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

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.

Austin correctly answered 92% of the questions on a geography quiz. Liz answered 47 of the 50 questions correctly. Which student got the most questions correctly.
(if you answer this may you please show your work)
Answer:liz scored better
Step-by-step explanation:
Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score
