Therefore , the solution of the given problem of perimeter comes out to be length = 16.8 and width = 50.4
Establish a perimeter.The perimeter, or total length, of a shape is referred to as its perimeter in geometry. A shape's perimeter is calculated by summing the lengths of all of its sides and edges. By adding together the lengths of all a shape's sides, one may determine its perimeter. The circumference of a field, for instance, will be 78 yards for a rectangle with dimensions of 24 yards long by 15 yards wide.
Here,
Given :
Perimeter of rectangle = 84 feet
Thus,
Length is 6 times more than its 2 time width
=> 6L = 2W
=> W = 3L
In the perimeter formula:
=> 3L + 2L =84
=> 5L = 84
=>L = 84/5
=>16.8
and
W = 3L
=> W = 3*16.8
=> W = 50.4
Therefore , the solution of the given problem of perimeter comes out to be length = 16.8 and width = 50.4

Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
9, 3, 1, ...
Answer: This is a geometric sequence and the common ratio is equal to 1/3.
Step-by-step explanation:
The given sequence is a geometric sequence with the common ratio 1/3.
What is Geometric Progression?Geometric progression is a sequence of numbers such that the ratio of two consecutive numbers is the same for whole sequence.
This ratio is common ratio.
The given sequence is 9, 3, 1, .......
Arithmetic sequence is a sequence where the numbers are arranged in an order such that the difference of two consecutive numbers, called common difference, is a constant.
3 - 9 = -6
1 - 3 = -2
Difference is not constant, so not an arithmetic sequence.
3/9 = 1/3
1/3 = 1/3
Ratio is constant.
So the sequence is geometric sequence.
And the common ratio in the simplest form is 1/3.
Hence the sequence is geometric with common ratio 1/3.

Mr. Klimek made his wife a rectangular vegetable garden. The width is 5 3/4 ft, and the length is 9 4/5 ft. Mr. Klimek calculated his garden to be 15 11/20 square feet. Is Mr. Klimek correct with his calculations? If he is, what did he do to find his answer. If he is incorrect, what did he specifically do wrong, what is the correct answer? Show and Explain.
Answer:
He is wrong. The right answer is 56.35. Or 56 7/20
Step-by-step explanation:
So lets go over what we know.
The width is 5 3/4ft.
The length is 9 4/5 ft.
The square feet is l*w, otherwise known as area.
So in this, we multiply 5 3/4 by 9 4/5.
Before we multiply however, lets put this into decimal form. Its easier to think of it this way.
3/4, or 3 divided by 4, is 0.75 So 5 3/4 is actually 5.75
4/5, or 4 divided by 5, is 0.80. So 9 4/5 is actually 9.8
Now lets multiply:
5.75*9.8
This might seem a bit confusing, but here is a step by step way of how I multiplied:
5*9 is 45. 5 times 8 is 40. Move the decimal since we used 8 instead of .8 its now:
45 and 4.0
Which is 49.
Now lets multiply 9.8 by the 0.75
3/4ths of 9 is 6.75. 3/4 of 8 is 6. Again, move over the decimal since we used 8 instead of .8 its now:
6.75 and .6
This is 7.35
Add that to 49:
56.35
So this is your answer.
Now, this is not what Mr.Klimek got.
So he is wrong.
The real answer is 56.35
To find the fractional form of this, we can take the decimal 35 and put it over 100:
35/100
Then simplfy. In this case 5 goes into both numbers. So:
7/20
So we have 56 7/20.
Now, the final question, what did Mr.Klimek do wrong?
Well, he added his length and width, instead of multiplying.
We already know what our two numbers equal: 9.8 and 5.75.
Lets add these:
9 plus 5 is 14. 0.8+0.75 is 1.55.
14+1.55=15.55
Using the method of transfering fractions I spoke of above:
55/100
5 goes into both numbers:
11/20
So adding the lenght and width, we got 15 11/20. This is what Mr.Klimek did.
So to sum up each answer:
The answer is 56.35 or 56 7/20Mr.Klimek is incorrect.Mr.Klimek added the length and Width, instead of multiplying.Hope this helps! :D

Each of the students in class writes a different 2 digit number on the whiteboard. The teacher claims that no matter what the students write there will be at least three numbers on the white board whose digits have the same sum what is the smallest number of students in the calls for the teacher to be correct?
Answer: The teacher's claim is that there will be at least three numbers on the whiteboard whose digits have the same sum, no matter what the students write. To see if this claim is true, we can consider different cases for the number of students in the class.
If there are only two students in the class, the teacher's claim is not true. The two students can write any two different two-digit numbers, and it's not guaranteed that the digits in those numbers will have the same sum.
If there are three students in the class, the teacher's claim is true. The three students can write any three different two-digit numbers, and at least one of those numbers is guaranteed to have digits that have the same sum as one of the other numbers.
If there are more than three students in the class, the teacher's claim is true. No matter what numbers the students write, there will always be at least three numbers whose digits have the same sum.
Therefore, the smallest number of students for the teacher's claim to be true is three students.
It's worth mentioning that the teacher's claim is not necessarily true for all cases, it's only true that any three numbers picked out of the two-digit numbers set, will have digits with the same sum.

The radius $r$ of a circle inscribed within three mutually externally tangent circles of radii $a$, $b$ and $c$ is given by \[\frac{1}{r}
The formula yields the radius $r$ of a circle that is inscribed within three circles with radii $a$, $b$, and $c$ that are mutually external tangents.
[tex][\frac{1}{r} = \frac{1}{a} + \frac{1}{b} + \frac{1}{c}][/tex]
The radius of the inscribed circle is related to the radii of the three mutually externally tangent circles using a method known as the radical centre formula. According to this equation, the reciprocals of the radii of the three externally tangent circles add up to the radius of the circle that is inscribed.
The power of point theorem states that the product of the distance between the point and the three points of tangency is equal to the product of the distance between the point and the centres of the circles. This formula is based on the fact that the circles are mutually externally tangent and their centres are collinear. It is crucial to note that the formula can only be used if the circles are mutually externally tangent; otherwise, it is invalid.

Your friend has read 6 more than twice as many pages as your
sister has read. Let 4
be the number of pages that your sister has
read. Write an expression for the number of pages that your friend
has read
Answer:
Expression: 2s + 6
# of Pages Friend Read: 14 pages
Step-by-step explanation:
Let's call the number of pages your sister has read, s, and the number of pages your friend has read, f. We will make our equation first. If your friend has read 6 more than twice as many pages as your sister has, your equation would look like this:
f = 2s + 6
That is your equation for how many pages your friend read, your expression would be just 2s + 6. Now, we will substitute in 4 for s, and we get:
f = 2 * 4 + 6
Multiplying gives:
f = 8 + 6 = 14
So your friend has read 14 pages.

Are parallel algorithms always faster than sequential algorithms?
Answer:
Step-by-step explanation:
Parallel algorithms are not always faster than sequential algorithms. In general, the speed of an algorithm depends on a variety of factors, including the complexity of the algorithm, the hardware it is running on, and the specific problem it is trying to solve.
There are some cases where a parallel algorithm can be faster than a sequential algorithm. For example, if an algorithm can be easily divided into smaller subproblems that can be solved independently and then combined to get the final result, it may be possible to speed up the overall computation by using a parallel algorithm to solve the subproblems in parallel. This can be particularly effective if the subproblems are large and can be solved using multiple processor cores or distributed across multiple computers.
However, there are also cases where a sequential algorithm may be faster than a parallel algorithm. For example, if the problem is relatively small and can be solved efficiently using a single processor, it may not be worth the overhead of dividing the problem into smaller subproblems and coordinating their solution in parallel. In addition, some algorithms may be more difficult to parallelize, or may not lend themselves well to a parallel solution, in which case a sequential algorithm may be a better choice.
Overall, it is important to carefully consider the specific problem and available hardware when deciding whether to use a parallel or sequential algorithm.

using multiple properties of exponents simplify the expression
2a^3b^-4/3a^5b^-2
2a³b⁻⁴/3a⁵b⁻² = 2/3(ab)²
What are exponents?The exponent of a number shows how many times the number is multiplied by itself.
Example: 2×2×2×2 can be written as 24, as 2 is multiplied by itself 4 times. Here, 2 is called the "base" and 4 is called the "exponent" or "power."
In general, xⁿ means that x is multiplied by itself for n times.
Properties of exponents:
Law of Product: a ^m × a ^n = a ^(m + n)
Law of Quotient: a ^m/a ^n = a ^(m - n)
Law of Negative Exponent: a^-m = 1/a ^m
Law of Power of a Product: (ab)^m = a ^m . b ^m
Law of Power of a Quotient: (a/b) ^m = a ^m/b ^m
Given expression
2a³b⁻⁴/3a⁵b⁻²
= 2/3 . a³/a⁵ . b⁻⁴/b⁻²
Law of Negative Exponent: [tex]a^{-m} = 1/a^{m}[/tex]
= 2/3 . a³/a⁵ . b²/b⁴
Law of Quotient: [tex]a^{m} /a^{n} = a^{m-n}[/tex]
= 2/3 . a³⁻⁵ . b²⁻⁴
= 2/3 . a⁻² .b⁻²
Law of Power of a Product: [tex]a^{m} .b^{m}= (ab)^{m}[/tex]
= 2/3 . (ab)⁻²
Law of Negative Exponent: [tex]a^{-m} = 1/a^{m}[/tex]
= 2/3 . 1/(ab)²
= 2/3(ab)²
Hence the simplified expression of 2a³b⁻⁴/3a⁵b⁻² is 2/3(ab)².

Which linear equation shows a proportional relationship?
y equals two thirds times x
y equals negative 3 times x minus one seventh
y equals three fourths times x minus 5
y equals 3 times x plus 7
The linear equation that shows a proportional relationship is y equals two thirds times x.
A proportional relationship is a relationship between two variables in which one variable is a constant multiple of the other. In other words, if y is directly proportional to x, then y = kx for some constant k. This can also be written as y/x = k, where k is the constant of proportionality.
The linear equation that shows a proportional relationship is y = 2/3x.
It shows a direct relationship because the coefficient of x (2/3) is constant, and there is no constant term (y-intercept) which breaks the proportionality.
The other equations do not show a proportional relationship because they have a coefficient that varies with x or a constant term.

How can you tell if a linear system has infinitely many solutions?
A linear system has infinite solutions if it consists of exactly the same equations.
The 3 possible solutions of a linear system are:
- Unique or one solution
- Infinite solutions
- No solution
- If the linear equations are exactly (or can be transformed to exactly) the same equations, the solution is infinite.
Example:
3x + 2y = -4 ..... (equation 1)
6x = -4y - 8 ..... (equation 2)
Add 4y to both sides of equation 2:
6x + 4y = -8
Divide both sides by 3:
3x + 2y = -4
Hence, equation 2 is exactly the same as equation 1. If we plot their graphs, they will share the same graph. Any solution of equation 1 is also solution of equation 2. Therefore, this linear system has infinite solutions.
