The slope of the line passing through points A and B is 1/3.

The formula for the slope of a line to find the slope passing through points A and B. The formula is:

slope = (change in y) / (change in x)

Let's label the coordinates of point A as (x₁, y₁) and the coordinates of point B as (x₂, y₂).

Then, substitute the values and calculate the slope:

slope = (y₂ - y₁) / (x₂ - x₁)

slope = (3 - 2) / (3 - 0)

slope = 1 / 3

Therefore, the slope of the line passing through points A and B is 1/3.

Answer:  the team won 154g / (g + 1) games and lost 154 / (g + 1) games.

Step-by-step explanation: The mathematical equation "W/L = g" is expressed in a concise manner, wherein "W" refers to weight, "L" refers to the length, and "g" represents the gravitational acceleration. This equation can be utilized in various scientific and academic disciplines, particularly in the field of physics, engineering, and mechanics. The relationship between weight, length, and gravitational acceleration can be further explored and examined through research studies and experiments.

The equation in consideration may be rendered less intricate through the process of multiplication of both sides by L.

"The equation W = gL" can be expressed in an academic manner as follows: The equation denoted by W = gL can be deduced as the product of the gravitational acceleration (g) and the length (L) of an object in a given direction. This equation is commonly used in physics to determine the work (W) performed on an object as a result of a force acting on it, in correlation with the displacement it undergoes in the same direction.

It is understood that the summation of the games won and lost by the team is equivalent to the overall number of games that were played.

The equation denoting the sum of W and L yields a value of 154.

The first equation may now be replaced in the second equation, resulting in:

The mathematical equation GL + L = 154 represents an algebraic expression, where 'G' and 'L' are variables that denote unknown numerical values. The equation dictates that the sum of the values assigned to 'GL' and 'L' must equal to 154. Such equations are commonly used to solve numerical problems in mathematics and related disciplines.

One should perform the mathematical operation of factoring out the variable L on the left-hand side.

The equation L(g + 1) = 154 can be expressed with greater academic rigor.

The sides can be divided by (g + 1) to simplify the equation.

The equation L = 154 / (g + 1) represents a mathematical relationship wherein L is determined by dividing 154 by the sum of g and one.

The aforementioned equation can be utilized to derive a solution for W, ascertaining the relationship that W is equivalent to gL.

The presented expression, W = g(154 / (g + 1)), exhibits a mathematical relationship between the variables W and g, whereby W is a function of g. The numerator of the parenthetical expression, 154, is divided by the sum of g and one, then this ratio is multiplied by g to produce the value of W. The formula can be utilized in various disciplines, such as physics, engineering, and mathematics.

The expression can be simplified to yield:

The expression W can be denoted as 154g / (g + 1) in accordance with the commonly recognized conventions of formal academic writing.

Step-by-step explanation:

To calculate the volume of the sandcastle decoration in the fish tank, we can use the formula:

Volume of the decoration = Total volume of water after adding the decoration - Volume of water before adding the decoration

The volume of water before adding the decoration is the volume of the rectangular prism formed by the fish tank, which is:

Volume of water before = Length x Width x Height

= 16 x 15 x 12

= 2,880 cubic inches

After Kyle added the sandcastle decoration, the water level rose to 13 inches. This means the volume of water in the tank increased by the volume of the decoration. The new volume of water in the tank is:

Volume of water after = Length x Width x Height

= 16 x 15 x 13

= 3,120 cubic inches

Therefore, the volume of the sandcastle decoration is:Volume of decoration = Volume of water after - Volume of water before

= 3,120 - 2,880

= 240 cubic inches

Therefore, the volume of the sandcastle decoration in the fish tank is 240 cubic inches.
