what is the absolute value of a number ?
Answer:
Step-by-step explanation:
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
Answer:
See below
Step-by-step explanation:
The absolute value of a number is its POSITIVE distance from 0. We notate absolute value as |x|.
For example, if you wanted to determine the absolute value of -5, you would write it as |-5| which is 5.
-5 is 5 away from 0, so this confirms the answer is right.

Answer:
table 3 and table 12 show a proportional relationship
The coordinate points in the table D shows proportional relationship. Therefore, option D is the correct answer.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
A) Slope= (3-2)/(4.5-3) =1/1.5
Slope= (8-4)/(12-8) = 4/4 =1
B) Slope= (60-15)/(4-1)
= 45/5
= 15
Slope= (120-70)/10-5)
= 50/5
= 10
C) Slope= (3-2)/(12-8)
= 1/4
Slope= (5-4)/(16-14
= 1/2
D) Slope= (10-5)/(2-1)
= 5
Slope= (35-25)/(7-5)
= 10/2
= 5
Therefore, option D is the correct answer.

Explain how to solve for coordinates for the equation x + y = 7. Include some coordinates in your answer.
Answer:
y = mx + b would be your starting equation. You need two coordinates for to find your slope (mx). You multiple your slope (m) with your x-coordinate given (x). Then after multiplying, you subtract that with y to find your b. Thus, the answer. You'll want to ask yoru teacher for more help if you don't get it. :)

In a group of 120 people, 90 have an age of more 30 years, and the others have an age of less than 20 years. If a person is selected at random from this group, what is the probability the person's age is less than 20?
Answer:
0.25
Step-by-step explanation:
Number of people whose age is less than 20 is given by
120 - 90 = 30
Probability P that a person selected at random from the group is less than 20 is gieven by

find the area of quadrilateral KLMN
Step-by-step explanation:
I just answered this ...
the first thing we notice : the quadrilateral has 2 pairs of equally long sides with 2 angles being openly 90°.
so, we are dealing with a rectangle here.
we know that one pair of the sides (NK = LM) are 24 cm long.
and we know that KL:LM = 3:4.
that means that the pair KL = MN are the shorter sides of the rectangle. and their length is according to the ratio 3/4 of NK=LM.
3/4 × 24 = 18 cm
the area of that rectangle is therefore
18 × 24 = 432 cm²
What is the area of this polygon?
A = 400 cm²
A = 338 cm²
A = 316 cm²
A = 238 cm²
The area of the polygon is the sum of the area of rectangle + area of triangle = 316 cm². (Option C)
Area of PolygonThe polygon is composed of a triangle and a rectangle.
Area of the polygon = Area of Triangle + Area of Rectangle
Area of Rectangle = length × width
Length = 21 cm
Width = 14 cm
Area of rectangle = 21 × 14 = 294 cm²
Area of Triangle = 1/2(base × height)
Base = 21 - 10 = 11 cm
Height = 18 - 14 = 4 cm
Area = 1/2(11 × 4) = 22 cm²
Therefore:
Area of Polygon = 294 + 22 = 316 cm².

The actual length of a desk is 58 1/2 inches. Margaret estimates the length of the desk and finds her percent error to be less than 5%.
What range of values represents Margaret's estimated length?
Enter your answers as decimals or mixed numbers in simplest form by filling in the boxes.
Answer:
Margaret's estimated length is between 55.575 inches and 61.425 inches.
Step-by-step explanation:
I believe this is enough explanation
Percent error is error in percentage compared to original measurement. The range of values representing Margaret's estimated length is [tex]M \in [ 55.575, \: \: 61.425] \: \rm (in \: inches)\\[/tex]
How to calculate the range of estimated measurement from percent error?If the measurement of the object is measured to be M, and the percent error in the measurement is estimated to be E%, and O is the original measurement of the object being measured then:
[tex]\rm M \in O \pm E\% \: \rm of \: \rm O[/tex]
where O is the original measurement of the object being measured.
This decides the range of values in which the original measurement can fall in. It is [tex]\rm [ O - \text{E\% of O}, \: \: O + \text{E\% of O}][/tex]
For the given case, we have:
Original measurement of the desk = O = [tex]58\dfrac{1}{2} = 58 + 0.5 = 58.5 \: \rm inches[/tex]
E% = percent error in measurement = 5%
Let M denotes the estimated measurement of the desk by Margaret.
Then, [tex]M \in \rm [ 58.5 - \text{5\% of 58.5}, \: \: 58.5 + \text{5\% of 58.5}] \: \rm (in \: inches)[/tex]
5% of 58.5 is:
[tex]\dfrac{58.5}{100} \times 5 = 2.925[/tex] (inches).
Thus, the value of M will lie in:
[tex]M \in \rm [ 58.5 - 2.925, \: \: 58.5 +2.925] \: \rm (in \: inches)\\\\M \in [ 55.575, \: \: 61.425] \: \rm (in \: inches)\\[/tex]
Thus, the range of values representing Margaret's estimated length is [tex]M \in [ 55.575, \: \: 61.425] \: \rm (in \: inches)\\[/tex]

Two trains leave stations 240 miles apart at the same time and travel toward each other. One train travels at 110 miles per hour while the other travels at 90
miles per hour. How long will it take for the two trains to meet?
Answer:
1.2 hours
Step-by-step explanation:
240=(110+90)t
240=200t
t=6/5
t=1.2
It will take 1.2 hours (or 1 hour and 12 minutes) for the two trains to meet.
To find how long it will take for the two trains to meet, we can use the concept of relative speed. When two objects are moving towards each other, their relative speed is the sum of their individual speeds.
Let's calculate the relative speed of the two trains:
Relative Speed = Speed of Train A + Speed of Train B
Relative Speed = 110 miles per hour + 90 miles per hour
Relative Speed = 200 miles per hour
Now, the distance between the two trains is 240 miles. To find the time it takes for them to meet, we can use the formula:
Time = Distance / Relative Speed
Time = 240 miles / 200 miles per hour
Time = 1.2 hours
So, it will take 1.2 hours (or 1 hour and 12 minutes) for the two trains to meet.
