What is the absolute value of 6.4?
Absolute value of 6.4 is 6.4 itself.
What is the number line?A horizontal line with evenly spaced numerical increments is called a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that if corresponds to, such as when graphing a point.
Since, Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.
Thus, the absolute value of a positive number is always positive
Therefore, the Absolute value of 6.4 is 6.4.

Measuring how long the large mouth bass you caught while fishing to the nearest foot.
The number of party favors needed for a birthday party by the whole number.
The volume of water in a water bottle to the nearest fluid Ounce.
The cost of new laptop plus tax calculated to the nearest tenth.
Using unit measurement concepts, it is found that the correct options are:
The distance for a flight from Georgia to Texas to the nearest mile.Measuring how long the large mouth bass you caught while fishing to the nearest foot. The number of party favors needed for a birthday party by the whole number.The cost of new laptop plus tax calculated to the nearest tenth.----------------------------------
When measurements are made, the unit used is a big consideration, to give accuracy to the measurement. For example, measuring a person's height is kilometres would not give an accurate representation.----------------------------------
In the first option, for distance between cities or states, miles is the most widely used metric, so this option is correct.In the second option, heights of mouth bass are usually measured in inches, which is easily converted to feet(dividing by 12), and thus, this option is correct.In the third option, for each person, there is usually a favor, thus, whole number is an accurate metric, and this option is correct.In the fourth option, volume of water is usually measured in liters, and fluid ounces are way smaller than liters, thus not giving an accurate representation.In the fifth option, costs of products, especially expensive products such as laptops, are rounded to the nearest tenth, and thus, this option is correct.A similar problem is given at https://brainly.com/question/16563559

What is an equation of the line that passes through the points (-5, -8)(−5,−8) and (-4, -6)(−4,−6)?
Answer:
Step-by-step explanation:
General equation of a line is y= mx+b,
where m is the slope and b is the y- intercept
For points (-5, -8) and (-4, -6) the slope is
m= difference in y / difference in x
m = [-6 - (-8)] / [-4 - (- 5)] = (-6+8)/(-4+5) = 2/1 =2
Now we know that y= 2x+b , to find b substitute the coordinate (x, y) with coordinate (-4, -6) -you could pick the other point if you want will work because both points are on the line.
-6 = 2(-4) +b , multiply
-6 = -8 + b, add 8 to both sides
-6+8 =b , add
2 =b
The equation of the line that passes through the points (-5, -8) and (-4, -6) is
y= 2x+2
First of all, you will find the gradient. The formula for finding the gradient is y2-y1 /x2-x1. - 6--8/-4--5.If two negatives meet they change to positive. - 6+8/-4+5=2/1,therefore the gradient is 2,after that then you will find the equation of the line. The formula for finding the equation of the line is y-y1=m(x-x1). y-(-8)=m(x--5),y+8=2(x+5),y+8=2x+10,y=2x+2.

What is the area of a circle with a diameter of 8 meters? Use 3.14 for pi, nothing else. Express in pi term and number term.
The two answers you are looking for are 16π m² and 50.24 m².
Solution:
Finding the area of the circle,
First, knowing what the area of a circle formula is:
A=πr²
Since knowing that the radius is half the length of the diameter,
If the diameter is 8, then the radius must be 4.
A=π(4)²
A=16π m²
Now, you have the first answer. If you want to express it differently,
Using 3.14 as pi,
So, therefore,
A=16(3.14)
A=50.24 m²
So, now, we can conclude that the two answers you are looking for for the area of this circle are 16π m² and/or 50.24 m².
Answer:
16pi and 50.24 m squared

5. Find the solutions of x^2 – X-30 = 0.
please show work on how to do it
Answer:
x=6, x= -5
Step-by-step explanation:
Factor the equation
x^2 - x - 30 = 0 ----> (x-6)(x+5)=0
Next find the solution by setting those in the paranthesis equal to zero.
x-6=0 ----> x= 6
x+5=0 ----> x= -5
Step-by-step explanation:
[tex] {x}^{2} - x - 30 = 0[/tex]
➡️ [tex] {x}^{2} + 5x - 6x - 30 = 0[/tex]
➡️ [tex]x \times (x + 5) - 6(x + 5) = 0[/tex]
➡️ [tex](x + 5) \times (x - 6) = 0[/tex]
➡️ [tex]x + 5 = 0[/tex]
➡️ [tex]x - 6 = 0[/tex]

Miguel Sebring took out a loan for $5,000 at 9.5% exact interest for 90 days. How much interest will Miguel pay?
Answer: Miguel will pay Rs 11,875.
Step-by-step explanation:
P = 5,000
R = 9.5%
T = 90 days
now changing time into years
360 days = 1 year
90 days = 1/360 * 90 = 1/4 years = 0.25 years
now
I = PTR/100
= (5,000*9.5*0.25)/100
= 11,875
A table is on sale for $179.20, which is 72% less than the regular price. What is the regular price?
Answer:
640
Step-by-step explanation:
price ÷ 1 - percent (as decimal)
179.20÷(1-0.72) = 640
Answer: Regular price = $640
Step-by-step explanation:
Given information
New price = $179.20
Rate of discount in price = 72%
Given expression
Original Price = New Price / (1 - Rate of discount)
Substitute values into the expression
Original Price = 179.20 / (1 - 72%)
Simplify values in parentheses
Original Price = 179.20 / 0.28
Original Price = $640

Three angles of a triangle are the 4x or (4x-2) and (3x+6). Find x
Answer: x = 16
Step-by-step explanation:
4x + 4x-2 + 3x + 6 = 180 (being sum of triangle)
or, 11x + 4= 180
or, 11x = 176
so, x = 176/11
so, x = 16

Answer:
It will ALWAYS be true!
Step-by-step explanation:
Inputting any real or imaginary numbers such as i or e, (which are also known as complex numbers), and when put in the place of x will ALWAYS equal one another. You could put 1, 2, 3, etc. all the way up to infinity and still get the two equations equal to each other.

I find a spreadsheet to be a convenient tool for repeated calculations using the same formula. Here, the distance between two points is given by ...
d = √((x2 -x1)² +(y2 -y1)²)
For example, the distance between the first two points is ...
d = √((300 -(-350))² +(-400 -200)²) = √(422500 +360000) ≈ 884.59
Other distances are calculated the same way. The results are shown in the attached spreadsheet, which also adds them up.
The path length is 2387.1 feet.
