Answer:
Option B.) 3 inches
Step-by-step explanation:
Let us first express some principles that we can use to solve our problem. Generally, the Volume of a Box is given by:
[tex]V=h*w*l[/tex]
where
[tex]V[/tex] : is the volume
[tex]h[/tex] : is the height
[tex]w[/tex] : is the width
[tex]l[/tex] : is the length
Now we know that:
Volume of Box A ( [tex]V_{A}[/tex] ) is Equal to Volume of Box B ( [tex]V_{B}[/tex] ) so we have:
[tex]V_{A}=(2in)(3in)(6in)\\V_{A}=36 in[/tex]
So now we can find the Length ( [tex]l_{B}[/tex] ) of Box B easily, as we now the volume along with the height and the width, as follow:
[tex]V_{A}=V_{B}=36in\\\\36in = (3in)(4in)l_{B}\\\\36in=(12in)l_{B}\\\\l_{B}=\frac{36in}{12in}\\ \\l_{B}=3in[/tex]
So the Length of Box B is 3 inches, thus Option B. is correct.

the geometric mean of 2 and 14 is 2√7.
What is geometric progression?
A geometric progression sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.
Given two numbers whose geometric mean needed to calculate
From the formula of Geometric mean
GM = [tex]\sqrt[n]{x_{1} x_{2} x_{3} ....x_{n} }[/tex]
Where GM = geometric mean
n = number of values
Xi = values to average
Thus,
GM = √(2 *14)
GM = 2√7
therefore, the geometric mean of 2 and 14 is 2√7.

The charge to ship a package from one town to another, C, is given below as a function of the weight of the object, w, in pounds.
C = $2.50 + $0.55w
If the shipping cost for Cathy's item was $7.29, what was its weight?
A.
18.7 pounds
B.
0.87 of a pound
C.
87 pounds
D.
8.7 pounds
D) 8.7lbs
Subtract $2.50 from the total cost, because that's a fixed number, then do more math and boom, just like magic, it's solved.
Answer:
8.7 pounds
Step-by-step explanation:
7.29 = 2.5 + 0.55 w
0.55 w = 7.29 - 2.5
0.55 w = 4.79
w = 4.79 / 0.55

I need help with this Geometry question.
Answer:
Given that AC ≅ BC, the sides are of equal measures.
CD is a side in both ΔACD and ΔBCD, so the side is equal in both triangles.
Given that CD if the bisector of ∠ACB, the two angles produced are equal: ∠ACD ≅ ∠BCD.
∠ACB is contained between AC and CD in ΔACD. ∠ACB is contained between BC and CD in ΔBCD.
Therefore by the SAS postulate, ΔACD ≅ ΔBCD.
Step-by-step explanation:
The SAS postulate says that if two triangles have a contained angle between two sides that are known to be equal in the other triangle, then the triangles are congruent.
Prove that two sides are equal, then prove that an angle that is between those two sides is also equal.
A student bought a piece of hard candy that is in the shape of a sphere. The candy has a radius of 3 centimeters.
Which of the following is closest to the volume of the piece of candy?
(Use 3.14 for π.)
Volume of piece candy is 113.04 cubic centimeter
Solution:
A student bought a piece of hard candy that is in the shape of a sphere
The candy has a radius of 3 centimeters
Radius = 3 cm
Use 3.14 for π
Volume of sphere is given as:
[tex]V = \frac{4}{3} \times \pi \times r^3[/tex]
Where, "r" is the radius of sphere
Therefore, volume of candy is given as:
[tex]V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04[/tex]

A bakery offers a sale price of $2.50 for 3 muffins. What is the price per dozen?
Answer:
$10.0
Step-by-step explanation:
We are given;
Sale price for 3 muffins is $2.50We are required to determine the price per dozen;
We need to know that a dozen contain 12 itemsTherefore;
A dozen of muffins has 12 muffinsThus;
3 muffins = $2.50
12 muffins = (12 ÷ 3) × $2.5
= 4 × $2.50
= $10.0
The Price of a dozen is thus $10.0

Answer:
The addition of given fractions is [tex]\frac{11}{12}[/tex]
Therefore [tex]\frac{1}{4}+\frac{2}{3}=\frac{11}{12}[/tex]
Step-by-step explanation:
Given fractional expression is [tex]\frac{1}{4}+\frac{2}{3}[/tex]
To find the addition of given fractions :
Adding the given fractions we get
[tex]\frac{1}{4}+\frac{2}{3}[/tex]
[tex]=\frac{1(3)+2(4)}{12}[/tex] ( here taking 12 as LCM )
[tex]=\frac{3+8}{12}[/tex]
[tex]=\frac{11}{12}[/tex]
Therefore [tex]\frac{1}{4}+\frac{2}{3}=\frac{11}{12}[/tex]
The addition of given fractions is [tex]\frac{11}{12}[/tex]
Does the equation y=9x^2+19 represent a linear function?
Because the equation has an (constant of 19/ exponent of 2) , it (can/cannot) be written in the form y=mx+b.
When the equation is graphed, the rate of change between different pairs of coordinates on the graph (is constant/varies) so the graph of the equation is a (curve/point/straight line)
Therefore, the equation represents a (linear/nonlinear) function.
Because the equation has an [tex]\boxed{\text{exponent of 2}}[/tex], it [tex]\boxed{\text{cannot}}[/tex] be written in the form y = mx+b
When the equation is graphed, the rate of change between different pairs of coordinates on the graph [tex]\boxed{\text{varies}}[/tex] so the graph of the equation is a [tex]\boxed{\text{curve}}[/tex]
Therefore, the equation represents a [tex]\boxed{\text{nonlinear}}[/tex] function.
-----------------------------------------------------------------------------------------------------
So in short, y = 9x^2+19 is not linear because it graphs out a curve that isn't a straight line.
More info: The equation y = 9x^2+19 is a quadratic function as the exponent of 2 is the largest exponent. The degree is 2 for the same reason. A parabola will be graphed in this case, which is a curved bowl-like shape. The lowest point of this parabola is at (0,19) which is also the y intercept. There are no x intercepts as this parabola is entirely above the x axis and it goes on forever upward. See the diagram below for the graph of y = 9x^2+19.
The equation y=9x²+19 represents a nonlinear function because it has an exponent of 2, which means it cannot be written in the linear form of y=mx+b. The graph of this equation is a curve, indicating a varying rate of change unlike a straight line which indicates a linear function.
Explanation:The given equation is y=9x²+19. Because the equation has an exponent of 2, it cannot be written in the form y=mx+b, which is the standard form of a linear equation. In linear function, the highest exponent is 1.
When the equation is graphed, the rate of change between different pairs of coordinates on the graph varies. So, the graph of this equation forms a curve. Linear functions have constant rates of change and their graph is a straight line.
Therefore, given the criteria, the equation y=9x²+19 represents a nonlinear function.

Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)
Answer:
The perimeter of the polygon = 18 units
The area of the polygon will be [tex]A=18[/tex] square units
Step-by-step explanation:
Computing the Perimeter of the Polygon:
Considering the polygon with vertices
W (11,2)X (11,8)Y (14,8)Z (14,2)As the polygon is drawn in coordinate plane as shown in figure a.
From the attached figure a, we can observe that
The length of the side [tex]WZ = 3[/tex] unitsThe length of the side [tex]ZY = 6[/tex] unitsThe length of the side [tex]WX = 6[/tex] unitsThe length of the side [tex]XY = 3[/tex] unitsSo, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.
The perimeter of the polygon = [tex]WZ + ZY + WX + XY[/tex]
= 3 + 6 + 6 + 3
= 18 units
Computing the Area of the Polygon:
Area can be calculated by multiplying the length and width of the polygon.
[tex]A=lw[/tex]
So, the area will be:
[tex]A=lw[/tex]
[tex]A=(3)(6)[/tex]
[tex]A=18[/tex]
Therefore, the area of the polygon will be [tex]A=18[/tex] square units

Frankenstein in this passage?
O
O
A. Peacefulness
B. Excitement
O
c. Distraction
O
D. Dread
SUBMIT
Answer:
The answer is: letter A, Peacefulness
Explanation:
Mary Shelley is the author of the book entitled, "Frankenstein." The story of the book centers on "Victor Frankenstein," a scientist and his monster creation. This creation of his, later on, asked for a female companion by threatening him. Victor, reluctantly, agreed on this under the monitoring of the creature. In the end of the story, Victor and his men in the ship were trapped in ice.
While Victor was on his journey to Geneva after his brother (William Frankenstein) died, he spoke in the passage above, "I contemplated the lake; the waters were placed; all around was calm, and the snowy mountains, 'the palaces of nature,' were not changed." This made him think how much nature brings peace to his soul that even after turmoil, he felt comforted by nature. Although he dreads to go back, the thought of the calm nature made him continue his journey.
Thus, this explains the answer, "Peacefulness."
