The distance travelled by the unicycle is 226.08 inches.
What is the distance travelled?The first step is to determine the circumference of the wheel of the unicycle. A circle is a bounded figure which points from its center to its circumference is equidistant. The circumference of a circle is the distance round the circle.
Circumference of a circle = 2πr
Where:
π = pi = 3.14 r = radius = diameter / 2 = 24 / 2 = 12 inches3.14 x 2 x 12 = 75.36 inches
The next step is to multiply the circumference of the unicycle by the number of revolutions the tire made.
Distance travelled = 3 x 75.36 inches = 226.08 inches

You want to fence off a rectangular area of yard using the back side of your house as one of the sides. You have a total of 150 yards of fence. If the area of the fenced in portion comes to 2,800 square yards, what are the dimensions of the fenced-in area? Show all work for full credit.
The dimensions of the fenced-in area is
either length = 35 yards and width = 80 yards ,
or length = 40 yards and width = 70 yards .
In the question ,
it is given that
the total length of the fence = 150 yards
let L be the length of the area to be fenced
let B be the width of the house
Given that one side of the area is fenced using the back side of the house
So, the perimeter of the area to be fenced is 2L+B
equating both the perimeter we get
2L+B=150
B=150-2L ....(i)
Given the area fenced-in portion = 2800 yards
also the fenced-in portion area = L×B
hence
L*B=2800
Substituting the values of B from equation(i) , we get
L*(150-2L)=2800
150L - 2L² = 2800
2L² - 150L + 2800 = 0
simplifying further , we get
L² - 75L + 1400 = 0
L² -40L -35L +1400 = 0
L(L-40) -35(L-40) = 0
(L-35)(L-40) = 0
So , L = 35 yards or L = 40 yards
Using L = 35 yards , we get B = 150-2(35) = 80 yards
and using L =40 yards , we get B = 150-2(40) = 70 yards .
Therefore , The dimensions of the fenced-in area is
either length = 35 yards and width = 80 yards ,
or length = 40 yards and width = 70 yards .

A shipping carton has the shape of right triangular prism. Thelength of the carton is 4 times the longer lag of the righttriangular base. The shorter leg of the base is 1/2 of the longerleg. If the volume is 5832 cubic inches what is the length of thecarton?
EXPLANATION
Let's see the facts:
Length = 4*longer leg
Shorter leg of the base= 1/2 longer leg
We know that Volume = 5832 = 1/2* length* longer leg* shorter leg
Let's call x to the longer leg, the variables are:
length= 4*longer leg= 4x --> x is the longer leg
Shorter leg= 1/2longer leg= 1/2x --> x is the longer leg
Substituting terms, the equation would be:
[tex]5832=\frac{1}{2}\cdot4x\cdot x\cdot\frac{1}{2}x[/tex]Multiplying like terms:
[tex]5832=\frac{4}{4}x^3[/tex]Simplifying:
[tex]5832=x^3[/tex]Switching sides:
[tex]x^3=5832[/tex]Isolating x:
[tex]x=\sqrt[3]{5832}[/tex]Solving the cubic root:
[tex]x=18[/tex]So, x is the value of the longer leg.
Now, we need to find the length, we know that length=4*longer leg
So, the length of the carton is 4*18= 72

What are mathematical operations?Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative integers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. The set that the values created are contained in is known as the codomain, while the set that the operation really produced is known as the codomain of definition, active codomain, image, or range. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.
A scalar can be multiplied by a vector to create another vector (a process known as scalar multiplication), and two vectors can be combined to make a scalar quantity in an inner product operation. An operation may or may not have specific characteristics, such as being idempotent, associative, commutative, or anticommutative.

What is transformation?
The transformation, or f: X → X, is the name given to a function, f, that maps to itself. The pre-image X becomes the picture X following the transformation. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point.
Example: A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.
We know that re-sizing an item uses a transition called dilation.
In the figure the dimensions of the figures differ by a factor of 2.
Thus, dilation of figure A by a factor of 2 shows figure A is similar to Figure B
