Answer:
Option C: 2 books for $14, 5 books for $35
Step-by-step explanation:
A proportional relationship between two quantities would always have a constant of proportionality. Thus,
Constant of proportionality, k = y/x
In this case,
x = quantity of books
y = price
Let's see which pair will have a constant of proportionality:
Option A: 4 books for $24,8 books for $40
24/4 = 6;
40/8 = 5.
No constant of proportionality.
Option B: 5 books for $25, 6 books for $36
25/5 = 5
36/6 = 6
No constant of proportionality.
Option C: 2 books for $14, 5 books for $35
14/2 = 7
35/5 = 7
Constant of proportionality, k = 7.
This pair represents a proportional relationship.
Option D: 3 books for $15, 7 books for $28
15/3 = 5
28/7 = 4
No constant of proportionality.

Step-by-step explanation:
The average score in an examination taken by 52 students of a class is 85. If the scores of the best 5 performers are not considered, the average score of the remaining students falls by 2. If, none of the first five highest scorers is not below 80 and if each of the 5 top scorers had distinct integral scores, find the maximum possible score of the topper.
Answer:
177
Step-by-step explanation:
If the top 5 performers are not considered, the average drops by 2.
Thus,average without top 5 performers = 85 - 2 = 83
Total scored with 5 table toppers = 52 × 85 = 4420
Total scored without 5 table toppers = 47 × 83 = 3901
Total scores of top 5 table toppers = 4420 - 3901 = 519
We are told that each of the 5 top scorers had distinct integral scores.
Also, all of them will score greater than 83.
Thus,possible maximum score of table topper = 519 - (84 + 85 + 86 + 87) = 177

A field of grass feeds 28 cows for 6 days. How many days would the same field feed 21 cows?
Answer:
Step-by-step explanation:
28 cows × 6 days = 168 cow-days
(168 cow-days)/(21 cows) = 8 days
If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.
How to calculate number of days?This question involves the use of inverse proportion to solve.
According to this question, a field of grass feeds 28 cows for 6 days. The number of days it would take 21 cows is calculated as follows:
28 cows is fed for 6 days
21 cows will be fed for (28 × 6) ÷ 21 = 8 days.
Therefore, If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.

The cost c varies directly as the numbers n of pencils is written as A. c = kn B. k+ cn C. n = k/c D. c =k/n
Answer:
A. c = kn
Step-by-step explanation:
The cost c varies directly as the numbers n of pencils
This means that c is a multiplication of a constant by n, which is the number of pencils. So the equation for the cost is given by:
[tex]c = kn[/tex]
In which k is the constant of proportionality, that is, the cost of each pencil. So the correct answer is given by option A.
Eliana worked 16 1/2 hours for the first week of the month and 16 1/4 hours the second week of the month. Her pay for these 2 weeks was $412.65. How much did Eliana earn per hour?
Answer:
She earned $12.60 per hour
Step-by-step explanation:
Pay was $412.65
Hours worked = 16.5 + 16.25 = 32.75 hrs
hourly rate = $$/hrs = 412.65/32.75 = 12.6
She earned $12.60 per hour

Solve b=y-my for y.
Answer:
y = [tex]\frac{b}{1-m}[/tex]
Step-by-step explanation:
In order to get y by itself, we need to pull y out of 1 and m on the right side.
b = y(1 - m) since y(1 - m) is the same as y - my.
Once we have pulled y out of 1 and m, we can divide both sides by 1 - m
[tex]\frac{b}{1 - m}[/tex] = [tex]\frac{y(1 - m)}{1 - m}[/tex]
We can cancel out the 1 - m on the right side since (1 - m) / (1 - m) = 1
Finally we get our answer:
[tex]\frac{b}{1-m}[/tex] = y
This is the same as y = [tex]\frac{b}{1-m}[/tex]

For the given triangle the statement that is true for length x is -
x < 9
What are triangles?
Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.
The length of 1 side is = 5 units
The length of second side is = 4 units
A key geometrical concept that connects the lengths of a triangle's sides is the triangle inequality theorem.
It stipulates that the length of the remaining side must be greater than the sum of the lengths of any two sides of a triangle.
The triangle inequality theorem can be written out as follows if a, b, and c are the lengths of a triangle's sides:
b + c > a
a + c > b
b + a > c
Since the sum for the given triangle is 5 + 4 = 9
So, the third side must be less than 9.
Therefore, the inequality is x < 9.
