Multiplication is the process of multiplying. The length of the 10 fence panels is 18 meters.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given the length of three fence panels is 5.4 meters.
The lenght of each length panel = 5.4m/3 = 1.8 meter
The length of 10 fence panel = 1.8 meter×10 = 18 meter
Hence, the length of the 10 fence panels is 18 meters.

{ Pisces04 }The Womens' World Record Marathon time has improved by 34.82% from Dale Grieg's (UK) time of 3 hrs 27 mins 45s in 1964 to Paula Radcliffe's (UK) time in 2003. Find Paula Radcliffe's World Record time.
Using proportions, it is found that Paula Radcliffe's World Record time was of 2h 15 min 25s.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In seconds, Dale Grieg's time is of:
3 x 3600 + 27 x 60 + 45 = 12,465s.
The Womens' World Record Marathon time has improved by 34.82%, that is, it was reduced by 34.82%, which means that the time is 65.18% of what it was, hence Paula Radcliffe's time is seconds is given by:
P = 0.6518 x 12465 = 8,125s.
In hours, minutes and seconds, we have that:
8,125s = 2h 15 min 25s.

A trader sold a tv for sh .18000 making a 20percent loss.For how much was he supposed to sell it in order to make 20percent profit.
Answer:
The trader was supposed to cell the TV for sh. 27000 in order to make 20% profit
==============
Let the cost price is x.
We have:
x - 20% = 18000Solve it for x:
x - 0.2x = 180000.8x = 18000x = 18000/0.8x = 22500The cost is 22500, find selling price with 20% profit:
22500 + 20% = 22500 + 0.2*22500 = 22500*1.2 = 27000For each experiment, determine whether events A and B are independent or dependent.
For the given experiments there are following outcomes.
A) Independent
b) Dependent
C) Dependent
D) Dependent
E) Independent
Probability can be defined as the ration of favorable outcomes to the total number of events.
For A)
A coin is tossed and a dice is flip. Both the event are independent of each other.
For B)
Choosing of clips have same total number of events that why both the events are dependent to each other.
For C)
It also have same number of total samples cause both cherries and nuts contained chocolate belongs to the same box. That's why its also dependent.
For D)
It is also dependent because the total number of sample is same for both the marbles.
For E)
It is independent, because for every box that picked reduces the size of sample and probability of picking new box wont depends on previous box.
Thus, this is how events are dependent and independent

Answer:
D : (0 ≤t ≤6)
R : (-2 ≤d ≤0)
Step-by-step explanation:
your domain is your x and your range is your y.
this means that you start by looking at your x axis. in this problem, x goes from 0 to 6, so 0 ≤t ≤6
this is the same for y.
y goes from -2 to 0 (remember that you read the y axis down and up, so you need to have the negative number written first)
so -2 ≤d ≤0
Answer:
(domain: 0 ≤ t ≤ 6)
(range: -2 ≤ d ≤ 0)
Step-by-step explanation:
domain of a function: all possible x-values
range of a function: all possible y-values
here, we know that we can't have negative time (note: time is along the x-axis and is x-variable; it is describing the domain)
(and yes, while time still goes on forever, this graph does not have an arrow on the end of it, meaning that is where we are considering time to stop--and because its an ≤ sign, it wouldn't be infinity)
so, time goes from 0 to 6
(domain: 0 ≤ t ≤ 6)
here, we also know that our submarine won't go above the water level (it's not going to keep floating up into space forever), so the maximum value of our range (depth) is going to be 0
we also won't be going any lower than where the toy starts--which we can see to be -2
so, the depth goes from -2 to 0
(range: -2 ≤ d ≤ 0)

21. For the following exercises, use the descriptions of each pair of lines given below to find the slopes of Line 1 and Line 2. Is each pair of lines parallel, perpendicular, or neither?
21. Line 1: Passes through (1, 7) and (5, 5)
Line 2: Passes through (−1, −3) and (1, 1)
Answer:
The given lines are perpendicular.
Step-by-step explanation:
In the question, two lines are given as line 1 passes through (1,7) and (5,5). Whereas, line 2 passes through (-1,-3) and (1,1).
It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.
To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.
Step 1 of 2
Find the slope of first line.
[tex]$$\begin{aligned}m_{1} &=\frac{5-7}{5-1} \\m_{1} &=\frac{-2}{4} \\m_{1} &=-\frac{1}{2}\end{aligned}$$[/tex]
Step 2 of 2
Find the slope of first line.
[tex]$$\begin{aligned}&m_{2}=\frac{1-(-3)}{1-(-1)} \\&m_{2}=\frac{4}{2} \\&m_{2}=2\end{aligned}$$[/tex]
And
[tex]$$\begin{aligned}&m_{1} m_{2}=-\frac{1}{2}(2) \\&m_{1} m_{2}=-1\end{aligned}$$[/tex]
Since, both slopes are reciprocal of each other.
Therefore, the lines are perpendicular.

What is function?
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
According to the function,
Let the function be represented by f(x).
Step 1- Multiplying the number x by 4 results in 4x.
Step 2 - Subtracting 2 from results give 4x - 2.

The true statements about the pool are
The drain is best measured using perimeter The area of the cover is 250 square yardsOne edge of the pool measures 10 ydHow to determine true statements?The given parameters are:
Length = 25 yardsWidth = 10 yardsDepth = 2 yardsTo measure the drain, we simply calculate the perimeter of the edge of the pool.
This means that (a) is correct
When the volume is calculated, the unit is cubic yard or yd³.
This means that (b) is wrong
The area of the cover is:
Area = Length * Width
This gives
Area = 25 yards * 10 yards
Evaluate
Area = 250 square yards
This means that (c) is correct
The length of the drain is calculated as:
Perimeter = 2 *(Length + Width)
This gives
Perimeter = 2 * (25 + 10)

Perimeter = 70
This means that (d) is wrong

Write the equation of the circle graphed below. (-5,-5)
Answer:
(x+5)² + (y+5)² = 18
Step-by-step explanation:
Since the outline of the circle intersects with the point (-8,2), you can substitute to find the equation of the circle in the form (x-h)² + (y-k)² = r². First the center of the circle is given in the form (h,k). So (-5, -5) → (x – (-5))² + (y – (-5))² = r² → (x + 5)² + (y + 5)² = r².
Then to find r², substitute the given point with x and y.
((-8) + 5)² + ((-2) + 5)² = r²
(-3)² + (3)² = r²
18 = r²
r² = 18.
