The dimensions of room are: Length = 15 feet and Width = 9 feet.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
we have,
A room's length is 3 feet less than twice its width.
The area of the room is 135 square feet.
let the width be x then length = 2x - 3.
So, Area of Room
135 = l w
135 = x (2x- 3)
2x² - 3x - 135= 0
2x² + 15x - 18x - 135 = 0
x (2x+ 15) - 9 (2x- 15)= 0
(2x+ 15)(x- 9)=0
x= -15/2 or x= 9.
Thus, the dimensions of room are:
Length = 2(9)-3 = 15 feet
Width = 9 feet

The Campbell family has a disposable income of $60,000 annually. Assume that their marginal propensity to consume is 0.8 (the Campbell family spends 80% of new disposable income on consumption) and that their autonomous consumption spending is equal to $10,000. What is the amount of the Campbell family\'s annual consumer spending?,
The annual consumer spending of the Campbell family is $58,000.
Explanation:To calculate the amount of the Campbell family's annual consumer spending, you need to consider their autonomous consumption spending and their marginal propensity to consume. The autonomous consumption spending is $10,000, which means that even if their disposable income is zero, they will still spend $10,000. The marginal propensity to consume is 0.8, so for every additional dollar of disposable income, they will spend 80 cents. To find the annual consumer spending, you can use the formula: Consumer Spending = Autonomous Consumption Spending + (Marginal Propensity to Consume * Disposable Income). In this case, the disposable income is $60,000, so the annual consumer spending would be $10,000 + (0.8 * $60,000) = $58,000.

The angle between 0 and 2 π in radians that is coterminal with the angle 62 9 π in radians is
8π/9 is coterminal with 62π/9 and lies between 0 and 2π.
Given that, the angle between 0 and 2 π in radians that is coterminal with the angle 62π/9 in radians.
What is the coterminal with the angle?The coterminal angles are the angles that have the same initial side and the same terminal sides. We determine the coterminal angle of a given angle by adding or subtracting 360° or 2π to it.
To find a coterminal angle, add or subtract any multiple of 2π, that is
62π/9 - 2π = (62π-18π)/9
44π/9 - 2π = 26π/9
26π/9 - 2π = 8π/9
Therefore, 8π/9 is coterminal with 62π/9 and lies between 0 and 2π.

If the height of Mount Everest is about 8.8×103 meters, and the height of the Empire State Building is about 3.8×102 meters, which of these statements is true?
Answer:
option C is correct, i.e. Mount Everest is about 23 times as tall as the Empire State Building .
Step-by-step explanation:
Given options are:-
A. There is no way to compare these heights .
B. Mount Everest is about 40 times as tall as the Empire State Building .
C. Mount Everest is about 23 times as tall as the Empire State Building .
D. The Empire State Building is about 23 times as tall as Mount Everest.
Given the height of Mount Everest is about 8.8×10^3 meters, and the height of the Empire State Building is about 3.8×10^2 meters.
Finding ratios of given heights:-
[tex]\frac{Mount\;\;Everest}{Empire\;\;State\;\;Building} =\frac{8.8*10^3m}{3.8*10^2m} \\\\\frac{Mount\;\;Everest}{Empire\;\;State\;\;Building} =23.15789474 \approx 23 \\\\Mount\;\;Everest=23*(Empire\;\;State\;\;Building)[/tex]
Hence, option C is correct, i.e. Mount Everest is about 23 times as tall as the Empire State Building .

The perimeter of to similar polygon is 20 and 28. On side of the smaller polygon is 4. Find the corresponding side of the larger polygon
Final answer:
The corresponding side of the larger polygon is 5.6 units, found by setting up a proportion between the sides and the perimeters of the similar polygons. Scaling a square's side length by 2 makes its area 4 times larger, reflecting the square of the scale factor.
Explanation:
To solve the problem of finding the corresponding side of the larger polygon, we must use the property that the perimeters of similar polygons are proportional to their corresponding sides. Given that the perimeters are 20 for the smaller polygon and 28 for the larger one, we can set up a proportion to find the length of the corresponding side.
Let x be the length of the corresponding side in the larger polygon. The ratio of the perimeters is the same as the ratio of any pair of corresponding sides. Since we have a side of the smaller polygon being 4, we would set up the proportion as follows:
4 / x = 20 / 28
Cross-multiplying to solve for x, we have:
4 x 28 = 20 x x
112 = 20x
x = 112 / 20
x = 5.6
Therefore, the corresponding side of the larger polygon is 5.6 units. In the context of squares, when scaling a square by a factor of 2, the area increases by the square of the scale factor. If the smaller square has a side of 4 inches, the larger square will have a side length of 8 inches. Hence, the area of the larger square is 64 square inches (8x8), which is 4 times larger than the area of the smaller square which is 16 square inches (4x4).

Which recursive equation represents the pattern?
an = an – 1 + 3(n – 1)
an = an – 1 + 3(n – 1)
an = an – 1 + (3n – 1)
an = an – 1 + (n – 1)3
Answer:
[tex]a_n=a_{n-1}+3^{n-1}[/tex]
Step-by-step explanation:
It is given that
If there is 1 child, there can be 0 interactions.
If there are 2 children, there can be 3 interactions.
If there are 3 children, there can be 12 interactions.
If there are 4 children, there can be 39 interactions.
It means we have,
[tex]a_1=0, a_2=3, a_3=12, a_4=39[/tex]
We need to find the recursive equation that represents the pattern.
[tex]a_2=3\Rightarrow 0+3=a_1+3[/tex]
[tex]a_3=12\Rightarrow 3+9=a_2+3^2[/tex]
[tex]a_4=39\Rightarrow 12+27=a_3+3^3[/tex]
Similarly,
[tex]a_n=a_{n-1}+3^{n-1}[/tex]
Therefore, the required recursive formula is [tex]a_n=a_{n-1}+3^{n-1}[/tex].
Alani uses 3/4 cup of pineapple juice to make one bread how much juice will she use to make 5 breads
To make five loaves of bread, Alani will use 3 3/4 cups of pineapple juice, calculated by multiplying the amount required for one loaf, which is 3/4 cup, by five.
To solve this, you multiply the amount of pineapple juice needed for one bread by the total number of breads.
Multiply the amount of juice for one bread by the number of breads: 3/4 cup × 5 = 15/4 cups.
Convert the improper fraction to a mixed number: 15/4 cups is equal to 3 3/4 cups.
Therefore, Alani will use 3 3/4 cups of pineapple juice to make five loaves of bread.

Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1.
The square of the sum of 7 times x and 3 would be written as
[tex](7x+3)^2[/tex]
and 4 times the difference of x and 1 is written as
