use the rectangle diagram at the right.Write and solve an inequality to find the value of x for which the perimeter of the rectangle is less than 120.
Answers
The perimeter is the sum of all the sides of a geometric figure, so
[tex]\begin{gathered} (x+4)+x+(x+4)+x<120 \\ x+4+x+x+4+x<120 \\ 4x+8<120 \end{gathered}[/tex]To resolve this inequality you can first subtract 8 from both sides
[tex]\begin{gathered} 4x+8-8<120-8 \\ 4x<112 \end{gathered}[/tex]Then you divide by 4 on both sides of the inequality
[tex]\begin{gathered} \frac{4x}{4}<\frac{112}{4} \\ x<28 \end{gathered}[/tex]Therefore, for the perimeter of the rectangle to be less than 120, its shortest side must measure less than 28.

The solutions of the equation x³ + 5x² = - x² + 5x + 3 when solved graphically is x = - 0.41, 1.09.
Draw a graph for each side, or component, of the equation and check to see where the curves intersect or are equal, to solve an equation graphically. The answers to the equation are the x values of these places.
Consider the equation,
x³ + 5x² = - x² + 5x + 3
Solving Equations Graphically:
The solution(s) of the equation f(x) = g(x) are the values of x where the graphs of f and g intersect.
Therefore,
f(x) = x³ + 5x² and g(x) = - x² + 5x + 3
By graphing the function we find the intersection of the two functions.
Hence, the graphs intersect each other at ( - 0.411, 0.776) and ( 1.092, 7.268).
Therefor,e the solution of the equation x³ + 5x² = - x² + 5x + 3 is x = - 0.41 and x = 1.09.

x as a variable can also be expressed as 1x.
so we can say that 2x + 1x
because x & y are two different type of variables. you think of y as a question mark ( ? ).

In this question, we have been given an equation y = -2x + 8
We need to find the x-intercept and y-intercept. Also, we need to write it as a coordinate (a, b)
To find the x-intercept we need to substitute y = 0 in the above equation.
0 = -2x + 8
2x = 8
x = 4
So, the x-intercept is (4, 0)
To find the y-intercept we need to substitute x = 0 in the above equation.
y = -2(0) + 8
y = 0 + 8
y = 8
So, the y-intercept is (0, 8)

Horatio left a campsite, hiking at a rate of 1 mile per hour. Ivan left 3 hours later, hiking at a rate of 2 miles per hour. How long will it take Ivan to catch up to Horatio?
Answers
Ivan will catch up to Horatio in 3 hours .
In the question ,
it is given that
speed of Horatio is 1 miles per hour
speed of Ivan is 2 miles per hour .
and Ivan leaves 3 hours late than Horatio .
Let "t" be the time ( in hours ) taken for Ivan to meet Horatio ,
So, the distance covered by Ivan will be 2*t .
Since Horatio left 3 hours before so the time taken for Horatio to meet Ivan is (t+3).
So, the distance covered by Horatio will be 1*(t+3) .
The distance covered for Horatio and Ivan will be equal ,
which means
2*t = 1*(t+3)
2t = t + 3
2t - t = 3
t = 3
Therefore , Ivan will catch up to Horatio in 3 hours .

They can sell their candy for $3 a box. If we jet x represent the boxes of candy sold, the number of
boxes they need to sell to break even can be found by solving the equation 3x + 500 = 3x. How
many boxes of candy to they need to sell to break even?
Answers
You can never achieve break even by selling any number of boxes of candy if it costs them an additional $3 to manufacture each box of candy.
What is Break even point?In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even."
Although these opportunity costs have been paid and then capital has received the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."
Fixed cost (in manufacturing) = $500
Manufacturing cost of each candy = $3
and selling price of candy = $3
let x be a box of candy sold,
hence for no of box to be sold for a break even,
3x + 500 = 3x
but if you see above equation, that has no solution
Hence by providing each candy at $3 with $500 fixed cost and selling cost again at $3 you cannot achieve a break-even point.
hence there is no solution, and you will never be able to achieve break even.

A tangent and a radius of a circle meet to form a 90 angle is a true statement about a tangent and a radius.
The straight line that "just touches" the curve at a particular location is known as the tangent line (or simply tangent) to a plane curve in geometry. A circle or sphere's radius is any line segment that connects the object's center to its perimeter in classical geometry; in more contemporary use, it also refers to the length of such line segments.
A tangent is a line that very slightly touches the circumference of a circle. The angle between a radius and a tangent is always exactly 90 degrees if the radius and circumference are drawn at the same location.

How high (in feet) is the ballon?
Answers
The height of balloon is 1.99 miles above the ground.
What is angle of depression ?In the event when the line of sight is directed downhill from the horizontal line, an angle is created with it. Angle of depression is the angle produced between the horizontal line and the observer's line of sight when the object being observed is below the level of the observer.
Let's give the balloon's height above the earth and the distance it is from the first milepost horizontally a name.
We can state the following if the angle of this milepost's depression is 24 degrees:
Tan(24)=[tex]\frac{h}{b}[/tex]
b = [tex]\frac{h}{tan(24)}[/tex]
We can state the following for the following milepost as there will be (b+1)miles horizontal distance of and a 20 degree depression at that location.
tan(20)=[tex]\frac{h}{b+1}[/tex]
b +1 = [tex]\frac{h}{tan(20)}[/tex]
Therefore, substituting equation 1
[tex]\frac{h}{tan(24)}[/tex] = [tex]\frac{h}{tan(20)} -1[/tex]
1 = [tex]\frac{h}{tan(20)}[/tex] - [tex]\frac{h}{tan(24)}[/tex]
1 = h× ( [tex]\frac{h}{tan(20)}[/tex] - [tex]\frac{h}{tan(24)}[/tex] )
h = 1.99 miles

The value of x is 4.
The perimeter of any shape is the sum of lengths of all its sides.
We are provided with the sides of triangle i.e., 5x-1, 5x-1 and 2.2x +10.
So, The perimeter of a triangle = sum of length of all three sides = (5x-1) + (5x-1) + (2.2x +10)
The perimeter of a triangle = 12.2x + 8 equation 1
Also, we are provided with the side of square i.e., 6.5x -11.8.

Answers
Using the highest common factor, the greatest number of identical binders that the teacher can make is 18.
What is the highest common factor?The highest common factor or multiple of the given numbers is the highest number that can divide them without a remainder.
We know that 2, 9, and 18 can divide 54, 36, and 72 without leaving a remainder.
We can see that the highest common factor is 18.
When we divide 54 by 18, the quotient is 3. If you divide 36 by 18, the quotient is 2. When you divide 72 by 18, the result is 4.
The number of lined paper = 54 pieces
The number of grid paper = 36 pieces
The number of dividers = 72 dividers
The common factors of 54, 36, and 72 are 2, 9, and 18.
