Find the constant of proportionality for the table of values and write in the form y = kx
A) y = 1/4x
B) y = 4x
C) y = 6x
D) y = 24x
Answers
Answer:
Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Number of lemons used is denoted by 'y'.
Number of glasses of lemonade is denoted by 'x'.
As we can observe that ,
[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]
so we can write i as
[tex]\frac{x}{y} = \frac{1}{4}[/tex]
By cross multiplication
y=4x
So, if write it in the form y=kx,
It will be y=4x.

Now, you will look at each chart for 3 x's above the number 4. You have now eliminated the middle two. Next, count how many 3's there are, which is 2. Both have those, so eliminating other choices is a no-go. Now, look at how many 5's you have, which is 2. Look at your charts... again, no choice ca be marked-off. Finally, look at how many 6's there are, which is 3. So, look at your last options and find which one has 3 total x's above the 6. And there you go, D.

Answers
Answer:
2.=3
Step-by-step explanation:
Answer:
3 inches
Step-by-step explanation:
The dimension of interest is the greatest common factor of 12 and 27.
3 · 4 = 12
3 · 9 = 27
The greatest common factor is 3.
Elena needs squares that are 3 inches on each side.
We need to find the common factor of 12 and 27 since they ask to find a square of the same sides. This plays a key part in making sure it fits in the shape correctly with no overlaps and gaps :)

In the following inequality, x ≥ −2, what type of circle would appear on the number line (open or closed circle) and in which direction would the arrow point on the number line(right or left)?
Also, what is a possible solution to x ≥ −2?
Please answer all of the questions in sentence form.
(10 Points)
Answers
Answer:
A closed circle would appear on the number line and the arrow should be pointing towards right. The possible solutions could be basically anything greater than or equal to -2, it could be -2, -1, 0, 1, 2, 3, 4 and so on.
Step-by-step explanation:
There are a few things to consider:
1. The inequality symbol:
⇒ [tex]\leq or \geq[/tex] always represented by a closed circle on the number line (this also means that the function x ≥ −2 would contain values greater than -2 but it WOULD also include -2 as an answer, but anything less than -2 would not be included).
⇒ < or > always represented by an open circle on the number line (This also means that the function would contain all numbers greater than -2 but NOT -2 or anything greater).
2. Where the Inequality sign opens:
⇒ If the inequality sign opens towards the variable (a letter) it means that all the values will be greater than the value given in the function. (For example x > 2, since the inequality sign is opening towards the x it means that all values in the solution set would be greater than two and thus the arrow would face the right side. The possible solution set could be 3, 4, 5 and so on)
⇒ If the inequality sign opens towards the number value given, it means that all the values will be less than the value given in the function. (For example, x < 2, in this case the inequality faces towards the number value given so the values for the answer set will have every value less than 2, the solution set would contain values like 1, 0, -1, and so on).

For B. you will do this: 2*72 + 6 = 144 + 6 = 150. So, no. You need 90 degrees.
For C. you will do this: 2*42 + 6 = 84 + 6 = 90. This is a possible answer choice, but you should keep going just in case.
For D. you will do this: 2*36 + 6 = 72 + 6 = 78. So, no because you need 90 degrees for a right angle. (A right angle is 90 degrees)

the number of points in the first five games of the football season are listed below. what is the mean number of points scored?
Answers
To find the mean, all you have to do is add each number and then divide by how many numbers you added.
So, 38 + 29 + 16 + 42 + 33 = 158. There were five numbers added, so the next step is to divide 158 by 5. That equals 31.6 as your answer.
The mean number of points scored is 31.6 from the number of points in the first five games of the football season
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The number of points in the first five games of the football season are listed in table.
We have to find the mean number of points scored.
Mean we get by dividing sum of scores of 5 games and number of games played.
sum of scores of 5 games = 38+29+16+42+33
=158
Total number of games = 5
Mean = 158/5
=31.6
Hence, the mean number of points scored is 31.6.

Answer:
E.6, mark the guy above me brainliest, they got it right and answered first.

Option E is the correct answer.
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
The volume of the cedar trunk is 3/4 cubic yard.
To find the number of cubic blocks with a side length of 1/2 yard, we can divide the volume of the trunk by the volume of each cubic block:
So,
(3/4 cubic yard) ÷ (1/2 yard)³
= (3/4 cubic yard) ÷ (1/8 cubic yard)
= 6 cubic blocks
Therefore,
Jimmy would need 6 cubic blocks with a side length of 1/2 yard to measure the volume of his trunk.
