What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Eric conducted an experiment in his science class and recorded the data in a table.
Eric’s science experiment, time (seconds), 3, 6, 9, 12, 15, 18, distance (ft), 18, 36, 54, 72, 90, 108.
Let x be the time and y be the distance.
Let the distance and time be linear to each other. Then the linear equation is given as
y - 36 = [(36 - 18) / (6 - 3)] (x - 6)
y - 36 = 6 (x - 6)
y = 36 + 6x - 36
y = 6x
Then the constant of proportionality that relates the distance traveled to the elapsed time represented by this data will be 6.

A storage box is 60 cm long, 45 cm wide, and 30 cm high. The lid is 10 cm high. What is the surface area of the box and its lid?
The formula for the surface area of a rectangular prism (the storage box) is given by: A=2(wl+hl+hw). In this instance, w = width, h = height, and l = length.
We will calculate the surface area of the box and lid by first determining the height with the storage box lid included.
The height is now 40 cm (= 30 + 10). The width is still 45 cm. The length is still 60 cm.
You can fill in these values: A = 2(wl+hl+hw) = 2((45 * 60) + (40 * 60) + (40 * 45)) = 13,800.

Black bird starts his flight path from (2, 0). his flight path reaches a maximum height of 20 yards and lands at point (38, 0).
The maximum height is 20 yards and the total horizontal distance is 36 yards, which is the distance between the point (2, 0) and (38, 0).
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have:
The blackbird starts his flight path from (2, 0). His flight path reaches a maximum height of 20 yards and lands at point (38, 0).
Here the bird path will be a parabola with a maximum height of 20 yards.
The total horizontal distance traveled by the bird = The distance between the points (2, 0) and (38, 0)
= √(38-2)²
= 36 yards
Thus, the maximum height is 20 yards and the total horizontal distance is 36 yards, which is the distance between the point (2, 0) and (38, 0).

Answer:
10 units.
Step-by-step explanation:
Given:
[tex]\text{Volume of prism = 2500 units}^{3}[/tex][tex]\text{Length: 25 units}[/tex][tex]\text{Width: 10 units}[/tex]Formula:
[tex]\text{Volume of rectangular prism = Length} \times \text{Width} \times \text{Height}[/tex]
Substitute the length, width, and the volume of the prism in the formula
[tex]\implies \text{2500 = 25} \times 10 \times \text{Height}[/tex]
Divide 25 × 10 to both sides of the equation to isolate "Height"
[tex]\implies \dfrac{\text{2500}}{25 \times 10} = \dfrac{25 \times 10 \times \text{Height}}{25\times 10}[/tex]
[tex]\implies \dfrac{\text{2500}}{25 \times 10} = \text{Height}[/tex]
Simplify the left hand side of the equation
[tex]\implies \dfrac{{25 \times 10 \times 10}}{25 \times 10} = \text{Height} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [2500 =25 \times 10 \times 10][/tex]
[tex]\implies \dfrac{{10}}{1} = 10 = \text{Height}[/tex]
Therefore, the measure of the height is 10 units.

The two-way table with 5 columns and 3 rows, where the first column is labeled Boys, girls, total, and the entries in the columns match the ones in the second option.
Option B is the correct answer.
What is the two-way table?A two-way table is a table used to display the frequency distribution of two categorical variables.
It is also called a contingency table because it helps to examine the relationship between two variables, to see if they are dependent or independent.
We have,
A 5-column table has 3 rows.
The first column has entries Boys, girls, total.
The second column is labeled A with entries 12, 16, 28.
The third column is labeled B with entries 24, 30, 54.
The fourth column is labeled C with entries 12, 12, 24.
The fifth column is labeled Total with entries 48, 58, 106, represents the given information.
To understand why this is the correct two-way table, let's go through each row and column of the table:
The first row of the table shows the number of boys and girls who took the test, as well as the total number of students.
We are told that there are 106 total sophomores, so the entry in the "total" column is 106.
We are also told that there are 48 boys who received an A, B, or C on the test, so the entry in the "total" column for boys is 48.
Subtracting this from the total number of students gives us the number of girls:
106 - 48 = 58.
The second row of the table shows the number of students who received an A on the test.
We are told that there are 28 total A's, and out of those, 16 were received by girls.
This means that 28 - 16 = 12 A's were received by boys.
Therefore, the entries in the "A" column are 12 for boys and 16 for girls, which matches the table.
The third row of the table shows the number of students who received a B on the test.
We are told that there are 54 total B's, and out of those, 30 were received by girls.
This means that 54 - 30 = 24 B's were received by boys.
Therefore, the entries in the "B" column are 24 for boys and 30 for girls, which matches the table.
The fourth row of the table shows the number of students who received a C on the test.
We are told that there are 24 total C's, and out of those, 12 were received by boys.
This means that 24 - 12 = 12 C's were received by girls.
Therefore, the entries in the "C" column are 12 for boys and 12 for girls, which matches the table.
Thus,
The two-way table with 5 columns and 3 rows, where the first column is labeled Boys, girls, total, and the entries in the columns match the ones in the second option.

If you were to draw lines between the three points, you would see that it makes a triangle, with leg lengths 6 and 5, like in the attached file.
To find the distance between Hillsboro and Middletown, or the hypotenuse of the triangle, use the Pythagorean Theorem:
6² + 5² = c²

If the radius of a sphere is doubled, does the volume also double? explain.
Answer: No, the volume is eight times as large
Step-by-step explanation:
We will test this. Let the radius equal 4, then we will double it to 8.
4 * 2 = 8
With a radius of 4, the volume is about 268 units³. With a radius of 8, the volume is about 2,145 units³.
2,145 / 268 = 8
The volume is not twice as large, it is eight times as large.
Why is this? In the formula, r is cubed. WIth an example of 2, 2 * 2 * 2 = 8.
