The dimensions of a room measure 12ft by 9ft. In a scale drawing of a room, 1 inch= 3ft. What are the dimensions of the room in the drawing?
Final answer:
To calculate the scale drawing dimensions of a room that measures 12ft by 9ft with a scale of 1 inch=3ft, divide each dimension by the scale factor. The room would be 4 inches by 3 inches on the scale drawing.
Explanation:
To find the dimensions of the room in the drawing when given that 1 inch=3 feet, we need to set up a conversion based on the scale provided. The room measures 12 feet by 9 feet, so we must divide each dimension by the scale factor to convert feet to inches in the drawing.
First, calculating the length:
12 feet ÷ 3 feet/inch = 4 inches
Next, calculating the width:
9 feet ÷ 3 feet/inch = 3 inches
Therefore, the dimensions of the room on the scale drawing would be 4 inches by 3 inches.

The mean absolute deviation is 1.74 inches for the badminton team and 3.02 inches for the basketball team. Which of the following conclusions can be drawn from the data?
The badminton players are all taller than the basketball players.
The basketball players are all taller than the badminton players.
There is more variability in the badminton team member heights.
There is more variability in the basketball team member heights.
There is more variability in the basketball team member heights.
Mean Absolute Deviation, or MAD, describes the variability of a model. The greater the MAD, the more variability there is in the data. Since the MAD of the basketball players is higher than that of the badminton players, the basketball team members' heights vary more.

d=1/2at^2 ; for a
solve for a
Answer:
a = 2d/t²
Step-by-step explanation:
1- Divide by 1/2 on both sides:
(d ÷ 1/2 = d × 2/1 = 2d)
2d = at²
2- Divide by t² on both sides:
2d/t² = a

show work please and will give brainlyist
Out of the given options, the number of students with blue eyes, brown eyes, and hazel eyes can be determined using the information provided in the question.
Explanation:Let's assume the number of students with hazel eyes is x. According to the given information, the number of students with blue eyes is 2 less than x, so it is x - 2. Additionally, there are twice as many students with brown eyes, so the number of students with brown eyes is 2x. The total number of students in the class is given as 34, so we can set up an equation:
x + (x - 2) + 2x = 34
Simplifying this equation, we get 4x - 2 = 34. Adding 2 to both sides, we have 4x = 36. Dividing both sides by 4, we find that x = 9.
Therefore, the number of students with blue eyes is 9 - 2 = 7, the number of students with brown eyes is 2(9) = 18, and the number of students with hazel eyes is 9. Thus, the correct options are a. 8, c. 12, and f. 34.

The width and length of the bulletin board are whole numbers what is the width of the bulletin board if the length is 4 feet
The width of the bulletin board cannot be determined with the given information, as any whole number could be the width if only the length is known to be 4 feet.
Explanation:The question asks for the width of the bulletin board given that the length is 4 feet, and we are told that both measurements are in whole numbers. Without additional information about the actual measurement of the width or the relation between the length and the width, we cannot determine the width exactly. Since the length is 4 feet, which is a whole number, the width could be any whole number. The width could be the same as the length if the bulletin board is square, or it could be different if the board is rectangular.
Since we know that 1 yard is equivalent to 3 feet, it's relevant when converting between these units of measure, but this information is not directly helpful for determining the width without further details. If we had a ratio, scale factor, or additional information regarding the relationship between the length and width, then we could proceed with a mathematical calculation to find the width. For example, if the bulletin board were to have a given aspect ratio or if the problem stated that the width is a certain multiple of the length, then we could use that information to calculate the width.
The width of the bulletin board is 4 feet.
Explanation:To find the width of the bulletin board, we need to know the scale factor between the length and width. Since the length is given as 4 feet, we can assume that the width is also in feet. Therefore, the width of the bulletin board is also 4 feet.
a rectangular porch has dimentions of (x+12) and (x+5) feet. If thr aria of the porch floor is 120 square feet, what is its length and width?
To find the length and width of the rectangular porch, solve the equation (x+12)(x+5) = 120 for x. The length is x+12 feet, and the width is x+5 feet. Substitute the value of x to find the length and width.
Explanation:To find the length and width of the rectangular porch, we need to solve the equation (x+12)(x+5) = 120 for x. Expanding the equation, we get x^2 + 17x + 60 = 120. Rearranging the terms and solving for x, we find x = 5. So the length of the porch is x+12 = 5+12 = 17 feet, and the width is x+5 = 5+5 = 10 feet. Therefore, the porch has a length of 17 feet and a width of 10 feet.

what are the factors of 2n^2 -5n- 42
The factors of the quadratic expression 2n^2 - 5n - 42 are found by looking for two numbers that multiply to -84n^2 and add up to -5n. The correct pair is 7n and -12n, leading to the factors (2n + 7) and (n - 6).
Explanation:The factors of 2n^2 - 5n - 42 need to be determined by finding two numbers that multiply to 2n^2 times -42 (which is -84n^2) and add up to -5n. To factor this quadratic expression, we should look for a pair of numbers that meet these criteria.
Upon inspecting possible pairs, we find that 7n and -12n are the numbers that work since (7n) * (-12n) = -84n^2 and 7n + (-12n) = -5n. The quadratic trinomial can be expressed as:
2n^2 - 5n - 42 = (2n + 7)(n - 6)
By factoring this way, we have broken down the expression into its factors, which are (2n + 7) and (n - 6).
The factors of the quadratic expression [tex]\(2n^2 - 5n - 42\)[/tex] are [tex]\(2n + 7\)[/tex] and [tex]\(n - 6\)[/tex].
To find the factors of the quadratic expression \(2n^2 - 5n - 42\), we can use the factoring method. This involves finding two numbers that multiply to give the product of the coefficient of \(n^2\) (which is 2) and the constant term (which is -42), and also add up to the coefficient of \(n\) (which is -5).
The product of the coefficient of [tex]\(n^2\)[/tex] and the constant term is:
[tex]\(2 \times -42 = -84\)[/tex]
Now we need two numbers that multiply to -84 and add up to -5. These numbers are -12 and 7 because:
[tex]\(-12 \times 7 = -84\)[/tex]
[tex]\(-12 + 7 = -5\)[/tex]
Now we can rewrite the middle term of the quadratic expression using -12 and 7:
[tex]\(2n^2 - 12n + 7n - 42\)[/tex]
Next, we can factor by grouping. Group the first two terms and the last two terms:
[tex]\(2n(n - 6) + 7(n - 6)\)[/tex]
Notice that [tex]\(n - 6\)[/tex] is a common factor. We can factor this out:
[tex]\((2n + 7)(n - 6)\)[/tex].

C) Points are (2,-24) and (5,-15)
Rate of change = [tex]\frac{-15+24}{5-2}=\frac{9}{3}= 3.[/tex]
D) Points are :(2,-12) and (6,-16)
Rate of change =[tex]\frac{-16+12}{6-2}=\frac{-4}{4}=-1.[/tex]
E) Points are (2, -19 ) and (6, -17)
Rate of change =[tex]\frac{-17+19}{6-2}=\frac{-2}{4}=\frac{-1}{2}.[/tex]
Option C has the greatest rate of change.
The increasing linear function with the greatest unit rate is represented by the table in option B. The unit rate is 0.5.
Explanation:The table that represents the increasing linear function with the greatest unit rate is option B (x y 2 14 6 12). In this table, as the value of x increases by 4, the value of y increases by 2. This gives us a unit rate of 2/4 or 0.5.
For the other options:
A. The unit rate is (-6)/3 = -2
C. The unit rate is 9/3 = 3
D. The unit rate is -4/4 = -1

one month charlie rented 2 movies 3 video games for a total of $21. The next month he rented 4 movies and 8 video games for a total of $53. Find the rental cost of each movies and each video game.
The cost to rent a movie is $2.25 and to rent a video game is $5.50, which was determined by solving a system of linear equations derived from the problem statement.
Explanation:This problem is a classic example of a system of linear equations, and we can solve it using either substitution or elimination method. Let's denote the cost of renting a movie as 'm' and the cost of a video game as 'v'. From the problem statement, we know:
2m + 3v = $214m + 8v = $53We can multiply the first equation by 2, giving us 4m + 6v = $42. Now if we subtract the second equation from this, we can solve for 'v':
(4m + 6v) - (4m + 8v) = $42 - $532v = $11v = $5.50Substitute 'v' back into the first equation to solve for 'm':
2m + 3($5.50) = $212m + $16.50 = $212m = $4.50m = $2.25Therefore, the cost to rent a movie is $2.25 and to rent a video game is $5.50.
