Scale drawing: a rectangle with length 4 feet and width 3.75 feet. Initial dimensions: a rectangle with length 24 feet and width 15 feet. New dimensions: a rectangle with length 20 feet and width 18.75 feet.
Abdul planned a pool to be 24-feet long. To fit in his yard, however, the pool can only be 20-feet long. Abdul’s ratio and work is below. Where did he make an error?
StartFraction 24 feet divided by 6 over 20 feet divided by 6 EndFraction = StartFraction 4 over 3 EndFraction
Abdul’s work is correct.
Abdul should have divided by 5, not 6.
Abdul should have divided by 4, not 6.
This problem has no change in the scale factor.
PLEASE ANSWER ASAP!!!
Answer:
He should have divided by 4, not 6....
Step-by-step explanation:
Just did the lesson
Abdul have done error by dividing with 6 instead of 5, So Abdul should have divided by 5, not 6 is correct option.
What is Area of Rectangle?The area of Rectangle is length times of width.
According to the information provided, the initial dimensions of the pool are a rectangle with length 24 feet and width 15 feet.
The corresponding dimensions in the drawing are a rectangle with length 4 feet and width 3.75 feet.
Therefore, the scale factor for the length is:
24/4 = 6
And the scale factor for the width is:
15 feet / 3.75 feet = 4
Abdul wants to fit the pool into a smaller space, so he needs to find the corresponding dimensions of the pool in the drawing that has a length of 20 feet.
To maintain the same scale, he needs to apply the same scale factor to the new length.
Thus, the new length in the drawing is:
20/6 = 3.33 feet
Similarly, he needs to apply the same scale factor to the new width to maintain the same scale.
Thus, the new width in the drawing is:
18.75/4 = 4.69 feet
Now, let's check Abdul's work:
24/6×6/20=4/3
Left side is not equal to right side.
Abdul should have divided by 5, not 6.
Hence, Abdul have done error by dividing with 6 instead of 5, So Abdul should have divided by 5, not 6 is correct option.

a triangle has vertices d(6,1), e(2,3) and f(-1,-3). show that triangle DEF is a right angle triangle and identify the right angle triangle
We'll need the slope formula which is
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\[/tex]
We subtract the y values together, and divide that over the difference in the x values when subtracted in the same order.
Let's find the slope of line DE
[tex]D = (x_1,y_1) = (6,1) \text{ and } E = (x_2,y_2) = (2,3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{3 - 1}{2 - 6}\\\\m = \frac{2}{-4}\\\\m = -\frac{1}{2}\\\\[/tex]
The slope of line DE is -1/2.
Next, compute the slope of line EF
[tex]E = (x_1,y_1) = (2,3) \text{ and } F = (x_2,y_2) = (-1,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-3 - 3}{-1 - 2}\\\\m = \frac{-6}{-3}\\\\m = 2\\\\[/tex]
The slope of line EF is 2.
Lastly, compute the slope of line FD
[tex]F = (x_1,y_1) = (-1,-3) \text{ and } D = (x_2,y_2) = (6,1)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{1 - (-3)}{6 - (-1)}\\\\m = \frac{1 + 3}{6 + 1}\\\\m = \frac{4}{7}\\\\[/tex]
The slope of line FD is 4/7.
--------------------------
To recap everything so far, we found the following:
slope of DE = -1/2slope of EF = 2slope of FD = 4/7The product of the first two slopes gets us (-1/2)*(2) = -1 showing that DE is perpendicular to EF.
Perpendicular slopes multiply to -1 as long as neither line is vertical nor horizontal.
Since DE is perpendicular to EF, this proves we have a 90 degree angle at point E.
Therefore triangle DEF is a right triangle.
Which represents the solution(s) of the system of equations, y = x2 – 6x 8 and y = –x 4? Determine the solution set by graphing. (1, 3) only (2, 0) and (4, 0) (1, 3) and (4, 0) no solutions.
The solution of the considered system of equation is represented by: Option C: (1,3) and (4,0)
What is a solution to a system of equations?For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)
For the considered case, the system of equations given to us is:
[tex]y = x^2 - 6x + 8\\y = -x + 4[/tex]
Plotting both's graph and finding the common points on both's graph, we get the common points as:
(1,3) and (4,0)
These points satisfy both the equations simultaneously.

Step-by-step explanation:
Omar grouped the terms and factored the gcf out of the groups of the polynomial 3x3 – 15x2 – 4x 20. his work is shown. step 1: (3x3 – 15x2) (–4x 20) step 2: 3x2(x – 5) 4(–x 5) omar noticed that he does not have a common factor. which accurately describes what omar should do next? omar should realize that his work shows that the polynomial is prime. omar should go back and regroup the terms in step 1 as (3x3 – 15x2) – (4x 20). in step 2, omar should factor only out of the first expression. omar should factor out a negative from one of the groups so the binomials will be the same.
The step that Omar should proceed with is given by: Option D: Omar should factor out a negative from one of the groups so the binomials will be the same.
What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomials.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
The polynomial that Omar is dealing with is:
[tex]3x^3 - 15x^2 -4x + 20[/tex]
We see that 3 times 5 = 15 and 4 times 5 = 20, so trying in that way:
[tex]3x^3 - 15x^2 -4x + 20 = 3x^2(x-5) + 4(-x + 5)[/tex]
Taking out a negative factor from second term would make the binomials same, after which we can take that common out, as shown below:
[tex]3x^3 - 15x^2 -4x + 20 = 3x^2(x-5) + 4(-x + 5) \\3x^3 - 15x^2 -4x + 20 = 3x^2(x-5) -4(x-5) \\3x^3 - 15x^2 -4x + 20 = (x-5)(3x^2-4)[/tex]
It successfully got factored, thus not a polynomial.
Thus,the step that Omar should proceed with is given by: Option D: Omar should factor out a negative from one of the groups so the binomials will be the same.

A triangular garden has an area of 112 ft2. Its height is 2 ft more than its base. Find the measure of the base.
Answer:
14 ft.
Step-by-step explanation:
First, we will assign variables to each value. If height is h, and base is b, then
1/2bh = 112 and h=b+2.
We will use substitution in this system of equations. first, we will isolate the b in bh/2=112. To do this we will multiply both sides by 2 to isolate the variables, so bh=224. Then, to isolate just one variable, in this case, b, we will divide 224 by h, getting us b=224/h.
Then, we will substitute b for this value in h+2=b, leaving us with h+2=224/h
Then isolate the variable. h will equal either -14 or 16. Because this is a geometric shape, the value of its sides cannot be negative, so it has a height of 16.
Then, plug this into the second equation. If the height is 2 ft more than the base, then the base will be 14 ft.
