We create a number line with a range from 0 to 1.0 and divide it into 5 equal segments to demonstrate the equality between 0.200 and 1/5.
What is a Number Line?The visual representation of numbers on a straight line, either horizontally or vertically, is known as a number line. When numbers are written down on a number line, it is straightforward for humans to compare them and perform basic arithmetic operations on them. One might assume that a number line starts at zero (0). There are only negative numbers to the left of zero and only positive numbers to the right of zero. In other words, as we move to the right on a number line, the value of the numbers increases. This shows that the numbers on the right are more numerous than those on the left.
We create a number line with a range from 0 to 1.0 and divide it into 5 equal segments to demonstrate the equality between 0.200 and 1/5.This line will include points at 0.2, 0.4, 0.6, 0.8, and 1.0.Next, we create a second number line that has five equally spaced segments and ranges from 0 to 5/5.This line will have the following points: 1, 2, 3, 5, 4, and 5/5.These values of 0.200 and 1/5 will be equivalent, as demonstrated by the equal segments.To know more about the number line, visit:

Answer: take a picture of it please
Step-by-step explanation:
Answer:
4.5
Step-by-step explanation:
To answer the problem:
PK * PN = PL^2
Let PN = x
8x = 10^2

x = 100/8
x = 12.5
KN = PN - PK
12.5 - 8 = 4.5 would be the length of segment KN.
Which constant should be added to the binomial x^2-14x so that it becomes a perfect square trinomial?
A. 49
B. 36
C. 16
D. 25
Answer:
A
Step-by-step explanation:
x² - 14x
using the method of completing the square
add ( half the coefficient of the x- term )² to x² - 14x
x² +2(- 7)x + (- 7)²
= x² - 14x + 49
= (x - 7)² ← perfect square
Simplify three eighths times the quantity 1 plus the square root of 49 end quantity squared minus the quantity four minus one end quantity cubed.

The given expression:
(3/8)*( 1 + √49)^2 - (4 - 1)^3
Can be simplified to -3.
So we have the equality:
(3/8)*( 1 + √49)^2 - (4 - 1)^3 = -3
Which means that the first option is the correct one.
How to simplify the given expression?Here we have the expression:
(3/8)*( 1 + √49)^2 - (4 - 1)^3
(I think is something like that)
And we want to simplify it, so first let's simplify the things inside the two parentheses.
The first one is:
1 + √49
We know that 7*7 = 49, then the square root of 49 is 7.
1 + √49 = 1 + 7 = 8
The other one is:
4 - 1 = 3
Replacing that in the expression we get:
(3/8)*( 1 + √49)^2 - (4 - 1)^3 = (3/8)*(8)^2 - (3)^3
Now we can solve the exponents:
8^2 = 8*8 = 64
3^3 = 3*3*3 = 27
Replacing that we get:
(3/8)*64 - 27 = 3*8 - 27 = 24 - 27 = -3
We conclude that the given expression:
(3/8)*( 1 + √49)^2 - (4 - 1)^3
Can be simplified to -3.

Find the missing term(s) of each arithmetic sequence. 2,□, □,□,-0.4,. . . .
The missing terms are 1.4, 0.8, 0.2
The series is ,
2, __, __, __, -0.4,...
To find the missing terms of the arithmetic sequence , we need to find the the common difference (d).
So formula to find the value of d
[tex]t_{n}[/tex] = a+ (n-1)d
Where [tex]t_{n}[/tex]= nth term of the series
a = first value of the sequence
n = number of terms
Here
[tex]t_{5}[/tex]= -0.4
a = 2
n = 5
-0.4= 2 + 4d
d = -0.6
Now we will add -0.6 from the first number of the series, so we get
[tex]t_{2}[/tex] = 2+(-0.6)
=2-0.6
= 1.4
[tex]t_{3}[/tex] = 1.4 - 0.6
= 0.8
[tex]t_{4}[/tex] = 0.8 - 0.6

Use the graph to interpret and match the appropriate intervals with their descriptions. Drag the tiles to the correct boxes. Not all tiles will be used. (-6.3,10) (4.9,10)(-9,0)(-3,10)(0,4.9)(-9,-3)
the order of titles according to the correct description boxes is (0, 4.9), (-3,10), (-9, -3) and then (4.9, 10) respectively.
We first look at the graph, and then, we analyze it, completing the tiles.
From the graph, the function is increasing in two intervals (-10,-9) and (4.9,10). The function is increasing over two interval, (-10, -9) and (4.9,10) , so the corresponding tile is (4.9, 10) for increasing in two intervals.
Between -9 and 4.9 the function is decreasing, so the corresponding tile is (0, 4.9).
An interval where the function is above the x-axis, so between -9 and -3, and then above 10, so the corresponding tile is (-9,-3) for interval over which the difference is positive.
Interval over which the difference is negative is when an interval where the function is below the x-axis, so before -10, and then between -3 and 10. Thus the corresponding tile is (-3,10).
Therefore, we can conclude the following relations
interval in which difference of the number of sales is decreasing→ (0, 4.9)
interval over which difference of the number of sales is negative→ (-3,10)
interval over which difference of the number of sales is positive→ (-9, -3)

x = number of people training all 3 sports.
This is because all 3 sports are needed for the triathlon
There are 35 swimmers total. 9 of which are also cyclers (but not runners), and there are 13 swimmers who are also runners (but not cyclers)
That leaves 35-9-13-x people who are swimmers only. I'll leave this expression un-simplified so you can see where the numbers are coming from. Take note of where I'm placing this in the venn diagram below.
There are 32 cyclers. Of this group, 9 are swimmers (but not runners) and 11 are runners (but not swimmers). That leaves 32-9-11-x people who are cyclers only.
There are 38 runners. Of this group, 13 are swimmers (but not cyclers) and 11 are cyclers (but not swimmers). That leaves 38-13-11-x people who are runners only.
All of these values are honestly hard to keep track of. This is why a visual approach using a Venn Diagram is recommended. See the diagram below.
The idea is that every value in the diagram then adds up to the 58 total attendees. This helps form the equation needed to solve for x.
Such an equation is possible because each attendee participates in at least one of the sports mentioned. No values will be outside of all three circles at the same time.

(in feet) and x is the horizontal distance traveled (in
feet). What is the height of the diving board?
Finding the equation of the parabola, it is found that the height of the diving board is of 24 feet.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
From the maximum height, it is found that the vertex is at (1,25), hence:
h = 1, k = 25.
Hence:
y = a(x - 1)² + 25.
You hit the water 6 feet from the diving board, hence y(6) = 0, meaning that we use it to find a as follows:
0 = a(6 - 1)² + 25
25a = -25.
a = -1.
Hence:
y = -(x - 1)² + 25.
The height of the diving board is y(0), hence:

the slope is therefore -7/1 = -7.
the slope is always the factor of x in the equation.
y = -7x + b
b is the y-intercept (the y value when x = 0).

By substitution, the solution of the system of equations, x + 6y = 2 and 5x + 4y = 36, is (8 , -1).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
x + 6y = 2 (equation 1)
5x + 4y = 36 (equation 2)
Using the first equation, find the value of one variable, lets say x, in terms of the other.
x + 6y = 2 (equation 1)
x = 2 - 6y
Substitute the value of x to the second equation.
5x + 4y = 36 (equation 2)
5(2 - 6y) + 4y = 36
10 - 30y + 4y = 36
Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
10 - 30y + 4y = 36
-30y + 4y = 36 - 10
-26y = 26
y = -1
Substitute the value of y in the equation of x.
x = 2 - 6y
x = 2 - 6(-1)
x = 2 + 6
x = 8
Hence, the solution of the given system of equations is (8 , -1).

Points that are on the same line are collinear. Use the definition of slope to determine whether the given points are collinear.Prove that the quadrilateral with vertices (2,5),(4,8),(7,6) , and (5,3) is a rectangle.
The quadrilateral with vertices (2 , 5), (4 , 8), (7 , 6), and (5 , 3) is a rectangle.
The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.
m = (y2 - y1)/(x2 - x1)
In a rectangle, each pair of adjacent side/line is perpendicular with each other, thus, the slope is negative reciprocal of one another. Also, opposite sides are parallel, thus their slopes are equal.
let A = (2 , 5)
B = (4 , 8)

slope of BC = slope of AD(6 - 8)/(7 - 4) = (3 - 5)/(5 - 2)
-2/3 = -2/3
slope of AB = negative reciprocal = slope BC(8 - 5)/(4 - 2) = (6 - 8)/(7 - 4)
3/2 = -2/3
slope of BC = negative reciprocal = slope CD(6 - 8)/(7 - 4) = (3 - 6)/(5 - 7)
-2/3 = 3/2
slope of CD = negative reciprocal = slope AD(3 - 6)/(5 - 7) = (3 - 5)/(5 - 2)

Suppose a balloon is filled with 5000 cm³ of helium. It then loses one fourth of its helium each day. How much helium will be left in the balloon at the start of the tenth day?
a. How can you write a sequence of numbers to represent this situation?
The situation can be represented by a geometric sequence with a(1) = 5000 and ratio or r = 3/4. At the start of the 10th day, the remaining helium volume is 375.42 cm³
Let a(n) be the volume of helium left in the balloon at the nth day.
Day 1: The balloon is filled with 5000 cm³ of helium. We can conclude the volume of helium in day 1 is:
a(1) = 5000.
Day 2: The volume of helium loses 1/4 from its initial volume. Hence,
a(2) = (1 - 1/4) . a(1)
= 3/4 . 5000 = 3/4 . 5000 = 3750
Day 3: The volume of helium loses 1/4 from its volume in day 2. Hence,
a(3) = (1 - 1/4) . a(2)
= 3/4 . 3750 = 2812.5
Continue the process, it will form a geometric sequence with a(1) = 5000 and ratio or r = 3/4.
To find the 10th term, use the nth term formula:
a(n) = a(1) . r^(n-1)
a(10) = 5000. (3/4)¹⁰⁻¹
= 5000. (3/4)⁹ ≈ 375.42
Hence, at the start of the 10th day, the remaining helium volume is 375.42 cm³

The required solution for the given arithmetic problems are,
A) 2/5
B) 72 / 125
C) 6, 3/4, 12/5, and 3/10
D) 4, 1/6 and 6
A) 12/25 times 15/18.
Division of two fractions performed as multiplication of numerator of one fraction with a denominator of another function over a denominator of one function with a numerator of another function.
= 12 / 25 * 15 / 18 = 2 / 5
Similarly
b) 12/25 divided by 15/18.
= [12 / 25 ] / 15 / 18
= 12 / 25 * 18 / 15
= 72 / 125
C) 6 and 3/4 times 1 and 2/5
6 * 1 = 6
3 / 4 * 1 = 3/4
6 * 2/5 = 12/5
3/4 * 2/5 = 3 / 10
D) 4 and 1/6 divided by 1 and 2/3.
= 4 / 1 = 4
= 1/6 / 1 = 1/6
= 4 / 2/3 = 6
= 1/6 / 2/3 = 1/4
Thus, the required solution for the given arithmetic problems is mentioned above.

Which are the factor pairs of 34?
1,34
2,17
3,11
4,8
5, 29
Answer: (1, 34) and (2, 17)
Step-by-step explanation:
Step 1: Divide 34 by the smallest prime factor.
34/2 = 17
Step 2: Since 17 itself is a prime number, therefore, it is divisible by 17 only.
17/17 = 1
Step 3: Now further division is not possible. Thus, we will consider 2 and 7 as the prime factors of 34.
