Which arrangement shows −5 1/2 , −5 , −6.4 , and −26/4 in order from least to greatest?
<3 thx
Answer:
-6.4, -5 1/2, -5, and -2 6/4.
Step-by-step explanation:
Arranging these negative values in order from least to greatest may be tricky if you are not familiar with your integer rules and operations. However, if you seem to understand, even a little, this way may be helpful to you.
All you need to know is this. positive and negative are opposites. Thus, if, for example, +2 is greater than +1 in positives, then -2 is less than -1 in negatives. So, in other words, think about it this way when you see a negative number, but you are used to positive numbers, just assume that the biggest number on the positive side is the smallest number on the negative side.
Therefore, if we were to use this method, we would result in -6.4, -5 1/2, -5, and -2 6/4. Since it would be the opposite in positives.

Applying the angle relationships, the measures of the numbered angles are:
m∠1 = 145°
m∠2 = 145°
m∠3 = 35°
m∠4 = 35°
m∠5 = 145°
m∠6 = 145°

How to Find the Measures of Angles Using Angle Relationships?The position of angles when a transversal intersects parallel lines determines the type of angle relationships that exist between the angles, and also their measure.
Based on angle relationships, the angle measures in the image are solved as follows:
m∠1 = 180 - 35 [linear pair angle relationship]
m∠1 = 145°
m∠2 = m∠1 [vertical angles]
m∠2 = 145°
m∠3 = 35° [vertical angles]
m∠4 = 35° [corresponding angles]
m∠5 = m∠2 [alternate interior angles]
m∠5 = 145°
m∠6 = m∠5 [vertical angles]
m∠6 = 145°
m∠7 = m∠4 [vertical angles]
m∠7 = 35°

I'll give you all 65 points that I have if you tell me how to do it because I want to understand the topic. thank you
Width of the box is the dimension which gives the gives maximum value.
Width of the box = 9 cm
Length of the box = 9 cm
Given,
The perimeter of the rectangular bottom of the box = 36 cm
The height of the box = 4 cm
We have to find the dimension which gives maximum value.
Volume = lwh
Perimeter = 2(l + w)
36 = 2l + 2w
l = (36 - 2w)/2
l = 18 - w
Now,
Volume = length × width × height
V = (18 - w) × w × 4
V = 72w - 4w²
Lets find w by using w = -b/2a
That is,
w = -72/2(-4) = -72/-8 = 9

Write an equation that represents the line.
Use exact numbers.
Answer:
y = -2x -3
Step-by-step explanation:
To write an equation we need two points that the line cuts through.
we then use the formula: Gradient = Rise/Run
the points chosen are (0,-3) and (1,-5)
Gradient = (-5--3)/(1-0)
= -2
to write the equation we need one known point, gradient and one unknown point say (x,y).
we therefore use the formula for gradient/slope
G = Rise/Run
-2 = y+3/x-0
-2x = y + 3
y = -2x -3
Answer:
y = - 2x - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (1, - 5) ← 2 points on the line
m = [tex]\frac{-5-(-3)}{1-0}[/tex] = [tex]\frac{-5+3}{1}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2

What are linear equations?A linear equation is an algebraic equation of the form y=mx+b that only contains a constant and a first-order (linear) component, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are the variables. Ax+By=C is the accepted form for two-variable linear equations. Finding both intercepts of an equation in this form is rather simple (x and y). If an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is said to be linear. The point-slope form, standard form, and slope-intercept form are the three primary types of linear equations.
As given
ages are consecutive even integers
Victoria > Tyee
So
Victoria's age = x
Tyee's age = x + 2
x(x + 2) = 80
= x² + 2x - 80
= x² + 8x - 10x - 80
Hence , the ages are 72 and 74.

Simplifying the answer
What is Real number ?
The value of a continuous quantity that can represent a distance along a line is a real number. René Descartes first used the word "real" in this meaning in the 17th century when he made a distinction between the real and imaginary roots of polynomials.
Solve : u² = -121
putting square root on both side
√u² = √ (-121)
u = (-11)
u = 11i
Since, there is no real square root of -121
If i is the imaginary unit then i = -1 and we find that
11i is square root of -121
Hence, the simplify answer for u² = -121 is 11i

The graph of the linear equation 4x - y = 8, with two points on the line is shown in the image attached below.
How to Graph a Linear Equation?If we know the slope, m, of the linear equation, which is the rise of the line over the run of the line, and also know the y-intercept value, b, we can graph a linear equation such that the slope of the line would be the value of m, and the point where the line intercepts the y-axis would be the value of b in the linear equation that is represented as y = mx + b.
Given the linear equation, 4x - y = 8, we can rewrite this in slope-intercept form as y = mx + b:
4x - y = 8
-y = -4x + 8 [subtraction property of equality]
y = 4x - 8 [division property of equality]
The slope, m, is 4, while the graph of the linear equation must intercept the y-axis at y = -8, because the y-intercept of the linear equation is b = -8.
Thus, the graph of 4x - y = 8 is shown below.

Five rays share a common endpoint. Set up an equation to find the value of x.
The equation that can be set up is, 2x° + 3x° + 36.5° + 36.5° + 2x° = 360°.
The value of x is: x = 41.
What are Angles around a Point?Angles that are formed around an endpoint but several rays will have a sum of 360 degrees when each of the angles formed around the endpoint is added together.
The diagram shows the angles that are formed by the five rays at a common endpoint. The angles are, 2x°, 3x°, 36.5°, 36.5°, and 2x°.
The sum of all these angles formed will give us 360 degrees. Therefore, the equation that would be created to find the value of x would be written as:
2x° + 3x° + 36.5° + 36.5° + 2x° = 360° [equation set up to find x]
Combine like terms
7x° + 73° = 360°
Subtract 73 from each side
7x° + 73° - 73° = 360° - 73° [subtraction property of equality]
7x = 287
Divide both sides by 7:

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.
Currently, the function is
f(x) = 7 x 4^x
Suppose,
y = f(x) = 7 x 4^x.
=> y = 7 x 4^x
Hence,
lny = ln (7 x 4^x).
We obtain using the logarithm equation
Hence,
ln y = ln7 + ln 4^x.
= ln y = ln7 + x ln4 .
Hence,
y equals e^(ln7 + x ln4).
=> y = e^ln7.e^(xln4) (xln4)
Using the exponential formula, we obtain
=> y = 7xln4
Consequently, y=f(x)=7.x.ln4
To determine function f's value (x)
7.x.ln7 = 0
As a result, For all possible values of x (x€R). To date,

The area of one surface of a cube is 19,600 sq. cm. If the cube is filled with water how many bottles of 4 litres each can be filled from it?
686 bottles of 4 liters each can be filled from this cube.
We can solve this problem by following a few steps.
As we know that a cube has 6 surfaces and each surface has a geometrical shape of a square. We also know that each side of a square is the same.
So, the surface area of a square ≡ Side × Side.
Let's assume the side as z
Now, the area of this square ≡ z × z = z²
∴ z² = 19600, as per the question.
We have to solve the equation, z² = 19600 Or, z = 140 ( by doing root both sides)
Now we know the side of the cube, then the volume of this cube is z³.
As, we know the volume of a cube ≡ side × side × side, as the height of a cube is also identical.
Volume of the cube = 140³ = 2,744,000 cc
1000 cc is considered as 1 liter. Therefore, this cube consists of, 2,744,000/1000 = 2744 liter of water.
Each bottle consists of 4 liters of water. Then we can fill, 2744/4 = 686 bottles of water.
