Answer:
width = 3 cm
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × width
given A = 27 and length = 9 , then
9 × width = 27 ( divide both sides by 9 )
width = 3 cm
❝ Area of a rectangle is ❞ = ❝ Length × Width ❞
✠ Given terms :
➺ Area = 27 cm²
➺ length = 9 cm
✠ Now, let's assume the width to be ❝ x cm ❞ and proceed to find its value using given relation ~
[tex]\qquad \: \twoheadrightarrow\sf Area = L × B [/tex]
[tex]\qquad \: \twoheadrightarrow\sf 27 = 9 × x [/tex]
[tex]\qquad \: \twoheadrightarrow \sf x = 27 ÷ 9[/tex]

A small rectangular package has a area of 9x square units and a height of 5 units. A large rectangular package has an area of 6 square units a d a height of 3x units more than the small box. What equation could be used to determine the volume of the large rectangular box?
Answers
The equation to determine the volume of the rectangular box is:
V = 6 * (5 + 3x)
Given that the area of the large rectangular package is 6 square units and its height is 3x units more than the small box,
To determine the volume of the large rectangular package, multiply its area by its height.
Volume of the large rectangular package = Area of the large rectangular package * Height of the large rectangular package
The area of the large rectangular package is given as 6 square units, so we substitute it into the equation:
Volume of the large rectangular package = 6 * Height of the large rectangular package
Now, the height of the large rectangular package is 3x units more than the small box. The height of the small box is 5 units, so we add 3x to it:
Height of the large rectangular package = 5 + 3x
Substituting this into the equation:
Volume of the large rectangular package = 6 * (5 + 3x)
Hence, the equation to determine the volume of the large rectangular package is: Volume = 6 * (5 + 3x)

(07.02 MC) what is the value of y in the equation 3(3y - 15) = 0?
Answers
Answer:
[tex]y = 5[/tex]
Step-by-step explanation:
Given equation:
[tex]3(3y - 15) = 0[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3(3y - 15)}{3} = \dfrac{0}{3}[/tex]
[tex]\implies 3y-15 = 0[/tex]
Add 15 to both sides:
[tex]\implies 3y-15 +15= 0+15[/tex]
[tex]\implies 3y=15[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3y}{3}=\dfrac{15}{3}[/tex]
[tex]\implies y=5[/tex]
Answer:
The value of y is 5.
Step-by-step explanation:
First, we will distribute 3 on (3y - 15) This means 3(3y) - 3(15) = 0. Now, we will multiply 3 by what is inside the parentheses for each value. This gives us 9y - 45 = 0. After that, we will add 45 to both sides, which leaves us with 9y = 45. Finally, we will divide 45 by 9 to give us the y value, 5. I hope this helped (:
A 2-column table with 4 rows. The first column labeled Elevation (meters) has entries 500, 1000, 1500, 2000. The second column labeled Temperature of air (degrees Celsius) has entries 11. 8, 8. 5, 5. 3, 2. 0. As elevation increases, temperature decreases. At which elevation will sound travel fastest? 500 meters 1,000 meters 1,500 meters 2,000 meters.
Answers
At an elevation of 500m, the sound will travel fastest.
Elevation Temp
500m 11.8°C
1000m 8.5°C
1500m 5.3°C
2000m 2.0°C
Why do sounds travel at a faster rate at high temeratures?We know that air molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly because the more is the medium, the more quickly sound waves propagate.
So, when the given temperature is maximum i.e. 11.8°C, the sound will travel fastest. The elevation corresponding to 11.8°C is 500m.
So, Sound will travel fastest at 500m elevation.
Therefore, At an elevation of 500m, the sound will travel fastest.

The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)
This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.
The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.
So overall, the inequality sign is "greater than or equal to". That leads to choice B.

Answer:
A) [tex]9 *l=54[/tex]
Step-by-step explanation:
The area of a rectangle is w*l=A, where w is the width and l is the length.
In this question, we are given 2 of the variables. We are told that the width is 9 and the area is 54. So, to find the equation that represents this situation, simply plug in the values.
This gives [tex]9 *l=54[/tex].Then, if needed we can find the length of the rectangle. Through the division property of equality, we know that dividing both sides of the equation maintains the equality of the equation. So, we can divide both sides by 9 to isolate the variable.

P is inversely proportional to q^3, when p has the value 27, q has the value 3. i) find the formula which expresses p in terms of q. P= r is directly proportional to q, when r has the value 10, q has the value 2. ii) prove that r=kp^n and so find the value of k and n.
Answers
Answer:
Step-by-step explanation:
i) If p is inversely proportional to q³, this is expressed as p ∝ q³
p = k/q³ where q is the proportionality constant.
Given p = 27 and q = 3
Substitute this values into the formula
27 = k/(3)³
27 = k/27
k = 27×27
k = 729
Substitute k = 1 into the formula
p = 729/(q)³
Hence the formula which expresses p in terms of q is p = 729/q³
ii) If r is directly proportional to q, it is expressed as r ∝ q
r = kq
If r = 10 and q = 2
Substitute
10 = 2k
k = 10/2
k = 5
The equation becomes
r = 5q... 1
From 1) p = 729/q³
q³ = 729/p
q = 9/³√p
q = 9/p^1/3....2
Substitute equation 2 into 1
r = 5(9/p^1/3)
r = 45p^-1/3
Compare r = 45p^-1/3 with r = kp^n
k = 45 and n = -1/3

If f(–2) = 0, what are all the factors of the function f (x) = x cubed minus 2 x squared minus 68 x minus 120? use the remainder theorem.
Answers
Then all factors of the function f(x) = x³ – 2x² – 68x – 120 is (x + 2), (x + 6), and (x – 10).
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
If f(–2) = 0, that mean one root is –2.
The function f(x) = x³ – 2x² – 68x – 120
We have the one factor is (x + 2)
Then the function can be written as
f(x) = (x + 2)(x² – 4x – 60)
f(x) = (x + 2)(x² – 10x + 6x – 60)
f(x) = (x + 2)[(x(x – 10) + 6(x – 10)]
f(x) = (x + 2)(x – 10)(x + 6)

Which value of x makes the equation 6 ( x − 2 ) = 3 − 9 x true?
Answers
Answer:

Step-by-step explanation:
6(x - 2) = 3 - 9x
We want to find x so that LHS = RHS/
6x - 12 = 3 - 9x
6x + 9x = 3 + 12
15x = 15
x = 1
Not 100% sure!
The value of x that makes the equation true is x = 1.
What is an expression?An expression in mathematics is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represents a value or quantity.
We can solve for x by simplifying the equation using the distributive property and combining like terms:
6(x - 2) = 3 - 9x
6x - 12 = 3 - 9x (distribute 6)
6x + 9x = 3 + 12 (add 9x and 12 to both sides)
15x = 15 (combine like terms)
x = 1 (divide both sides by 15)
Therefore, the value of x that makes the equation true is x = 1.
