A rectangle retaining wall has area of 15 square feet.The height of the wall is two feet less than its length.find the height and the length of the wall
Answer:
The wall is 3 ft high and 5 ft long.
Step-by-step explanation:
Recall: Area of the rectangular wall is A = (length)(height).
Let the height be represented by h. Then the length is represented by h + 2.
The formula A = (length)(height) then becomes A = h(h+2) = 15 ft², which, written in the standard form of a quadratic equation, is h² + 2h - 15 = 0.
Let's solve this last equation for h using completing the square:
h² + 2h - 15 = 0 becomes h² + 2h + 1 -1 - 15 = 0, or (h + 1)² = 16. Taking the square root of both sides, we get:
h + 1 = ±4, which is equivalent to h = 3 and h = -5. Discard the negative result. Then h = 3 and w = 3+2 = 5.
The wall is 3 ft high and 5 ft long. Its area is (3 ft)(5 ft) = 15 ft²
The height and the length of the rectangular wall is 3 feet and 5 feet respectively.
What is the height and the length of the wall?Area of a rectangle = 15 square feet
Length = x feet
Height = (x - 2) feet
Area of a rectangle = height × length
15 = x × (x - 2)
15 = x² - 2x
set to quadratic equation
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x(x - 5) + 3(x - 5) = 0
(x + 3)(x - 5) = 0
x + 3 = 0 or x - 5 = 0
x = -3 or x = 5
The length of a rectangle cannot be negative
Therefore,
Length = x feet
= 5 feet
Height = (x - 2) feet
= 5 - 2
= 3 feet

Hi So I know M∠2 + 63° (im pretty sure at least) but what does M∠3 equal?
Answer:
m<2 = 63
m<3 = 117
Step-by-step explanation:
<1 and <2 are alternate interior angles and are therefore equal. M<1 = 63 degrees, so m<2 must be the same thing.
<2 and <3 are on the same straight line.
They are supplementary.
Therefore they equal 180 degrees.
63 + m<3 = 180 Subtract 63 from both sides.
63 - 63 +m<3 = 180 - 63 Collect like terms
m<3 = 117
what is the independent variable and the dependent variable when a large 2 topping pizza, l, cost 2$ more than a medium 3 topping pizza, m,
Answer:
Although variables wouldn't really fit for this problem, if you were to graph it, the pizza types would be on the x axis and the cost would be on the y axis since the cost of the pizzas technically "depend" on the type of pizza.

1. In the figure below, ABC ~ PQR. If the area of ABC is 40 cm2, what is the area of PQR? Show your work.
Answer:
[tex]90cm^2[/tex]
Step-by-step explanation:
The side length AB of triangle ABC corresponds to side length of PQ of triangle PQR.
The scale factor from ABC to PQR is [tex]k=\frac{6}{4}=1.5[/tex]
The area of triangle PQR will change by [tex]k^2=1.5^2=2.25[/tex] centimeters square.
Since we know the area of triangle ABC to be [tex]40cm^2[/tex], the area of triangle PQR [tex]=2.25\times 40=90cm^2[/tex]
Answer:
The area of the triangle PQR is 90 cm^2.
Step-by-step explanation:
We are given two triangles, ABC and PQR, which are similar to each other.
If two triangles are similar, then the ratio of their areas is the square of the ratio of their sides.
Given that area of the triangle ABC is [tex]40cm^2[/tex], we are to find the area of the triangle PQR.
Finding the scale factor [tex]k=\frac{6}{4} =1.5[/tex]
So square of this scale factor will be [tex]k^2=(1.5)^2=2.25[/tex]
Area of triangle PQR = [tex]2.25 \times 40[/tex] = 90cm^2

one thousand and one million
North Carolina has three times the population of Utah and twice the
population of Oregon. Arkansas has 1 million people fewer than Oregon.
If the total population of these four states is 27 million, how many peo-
ple live in each state?
North Carolina = 3 * Utah
North Carolina = 2 * Oregon
Arkansas = Oregon - 1,000,000
North Carolina + Utah + Oregon + Arkansas = 27,000,000
North Carolina = 3 * Utah
Utah = 1/3 * North Carolina
Utah = 1/3 * (2 * Oregon)
(2 * Oregon) + (1/3 * (2 * Oregon)) + Oregon + (Oregon - 1,000,000) = 27,000,000
2O + (1/3 * 2O) + O + O - 1,000,000 = 27,000,000
2O + 2/3O + O + O - 1,000,000 = 27,000,000
4 2/3 O - 1,000,000 = 27,000,000
4 2/3 O = 28,000,000
O = 6,008,584
NC = 2O
NC = 2(6,008,584)
NC = 12,017,167
A = O - 1,000,000
A = 6,008,584 - 1,000,000
A = 5,008,584
NC = 3U
12,017,167 = 3U
U = 4,005,722
The populations of the four states are as follows:
- Utah has a population of 4 million.
- Oregon has a population of 6 million.
- North Carolina has a population of 12 million.
- Arkansas has a population of 5 million.
Let's denote the population of Utah, Oregon, and Arkansas as U, O, and A, respectively. According to the information given:
1. North Carolina has three times the population of Utah: [tex]\( NC = 3U \).[/tex]
2. North Carolina has twice the population of Oregon: [tex]\( NC = 2O \).[/tex]
3. Arkansas has 1 million people fewer than Oregon: [tex]\( A = O - 1 \).[/tex]
4. The total population of these four states is 27 million: [tex]\( U + O + A + NC = 27 \).[/tex]
From equations (1) and (2), we can equate the populations of Utah and Oregon since both are related to the population of North Carolina:
[tex]\( 3U = 2O \) or \( O = \frac{3}{2}U \).[/tex]
Now, substitute the value of O from equation (3) into the total population equation (4):
[tex]\( U + \frac{3}{2}U + ( \frac{3}{2}U - 1 ) + 3U = 27 \).[/tex]
Combine like terms:
[tex]\( U + \frac{3}{2}U + \frac{3}{2}U - 1 + 3U = 27 \),[/tex]
[tex]\( U + 3U + 3U - 1 = 27 \),[/tex]
[tex]\( 7U - 1 = 27 \).[/tex]
Now, solve for U:
[tex]\( 7U = 27 + 1 \),[/tex]
[tex]\( 7U = 28 \),[/tex]
[tex]\( U = \frac{28}{7} \),[/tex]
[tex]\( U = 4 \)[/tex] million.
Now that we have the population of Utah, we can find the populations of the other states:
[tex]\( O = \frac{3}{2}U = \frac{3}{2} \times 4 = 6 \)[/tex] million,
[tex]\( NC = 2O = 2 \times 6 = 12 \)[/tex] million,
[tex]\( A = O - 1 = 6 - 1 = 5 \)[/tex] million.

Which of the tollowing objects is considered to be one-dimensional because it has length but no width or height?
O A. Line segment
O B. Triangle
O C. Point
O D. Cube
Answer: A. Line segment
Step-by-step explanation:
A line is a one-dimensional geometric straight -undefined figure which has no thickness or depth . It extends infinitely in both directions.
A line segment is a part of a line having end-points on both the sides.
It has only length therefore, it is one dimensional.
Thus , the objects is considered to be one-dimensional because it has length but no width or height is a line segment.
The triangle is 2-dimensional , point has no-dimensions, and cube is 3-dimensional.
A line segment is the correct answer, as in mathematics it is considered one-dimensional because it only has length but no width or height. It extends in one direction, unlike a triangle and a cube, which have more dimensions. The point does not have length.
Explanation:In mathematics, a line segment is considered to be one-dimensional as it only possesses a property of length but no width or height. This means it only extends in one direction, often represented on a number line. In comparison, other options presented such as a triangle, point or cube have other dimensions involved. Specifically, a triangle falls in two dimensions as it has both length and width; a cube is a three-dimensional object possessing length, width, and height; and a point, though it lacks all three dimensions, is not accurate as it doesn't have length, which is the key criterion in the question.

The solution to the number 8000 in scientific notation is 8 * 10³
Expressing the number 8000 in scientific notationFrom the question, we have the following parameters that can be used in our computation:
Number = 8000
Multiply the number by 1
So, we have
Number = 8000 * 1
Express 1 as 1000/1000
So, we have the following representation
Number = 8000 * 1000/1000

The second step in solving 1/3n- 7/12 is to divide both sides of the equation by 1/3.
True Or false?
that is true if that's 1/3n=7/12
if it's 1/3n-7/12 then the first step is to equal it to zero
Yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.
What is a expression? What is a mathematical equation? What is Equation Modelling? What is denominator?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.
We have the equation -
(1/3)n = (7/12)
We have -
(1/3)n = (7/12)
Dividing both sides by (1/3), we get -
[(1/3)/(1/3)]n = [7/12 x 3]
n = 7/4
Therefore, yes, the second step in solving 1/3n = 7/12 is to divide both sides of the equation by 1/3.
