the length of a rectangle is 5 meters less twice it’s width. if the perimeter of the rectangular is 38 meters, then what is the value of the length
The length has a value of 9 meters
How to determine the length of the rectangle?From the question, we have the following parameters that can be used in our computation:
Length = 5 meters less twice it’s width
This means that
Length = 2Width - 5
The perimeter is given as
Perimeter = 38 meters
The perimeter is calculated as
Perimeter = 2 x (Length + Width)
So, we have
2 x (2Width - 5 + Width) = 38
Divide by 2
2Width - 5 + Width = 19
This gives
3Width= 21
Divide
Width - 7
Recall that Length = 2Width - 5
So, we have
Length = 2 * 7 - 5
Evaluate
Length = 9
Hence, the length is 9 meters

Answer: The profit from 2021 = $ -1.16 Million ($1.16 Million loss)
Step-by-step explanation:
Profit for 2022 = $ 1.38 Million
Profit for 2021 = Profit for 2022 - $ 2.54 Million
Algebraic equation:
p2021 = p2022 -$ 2.54 Million
p2021 = $ 1.38 Million - $ 2.54 Million

The remainder when 14 is divided by 3 is 2
What is remainder?
When we divide a number by another number if at the end if we have a number less than quotient and we can not divide further we say that the remaining number is remainder.
We are given a number as 14 and we divide 14 by 3
And on dividing 14 by 3 we get the quotient as 4 and remainder as 2.
Hence the remainder we get on dividing 14 by 3 is 2.

P(x) = x³- 2x² + 5x.
factor p completely
Answer:
P(x) = x (x²- 2x + 5)
Step-by-step explanation:
First factor x out:
P(x) = x (x²- 2x + 5)
Then, try to simplify (x²- 2x + 5):
However, there is no way to further simplify.
So, the answer should be x (x²- 2x + 5).

Step-by-step explanation:
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.
Arithmetic progression is S = 1/2n[2a+(n-1)d]
----------------------------------------
In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Geometric progression is Uₙ = arⁿ ⁻ ¹

Answer: √141
Step-by-step explanation:
a^2=c^2-b^2
The hypotenuse is larger in this question so we subtract them.
25^2-22^2=625-484=141
√141
Answer:
x = √141
or
x = 11.87
Step-by-step explanation:
is a right triangle, we solve it with the Pythagorean theorem ("In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides".)
x² = 25² - 22²
x² = 625 - 484
x² = 141
x = √141
or
x = 11.87

1. The public primary/secondary school dropout rate in Washington State is 6%. Suppose 35
individuals of primary/secondary school age are interviewed at random on a city street. What is
the probability that:
a. (5 points) Exactly 7 of them are dropouts?
The probability that exactly 7 individuals are dropouts out of 35 is 0.0033288.
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.
Given,
Probability of dropouts=p= 6%= 0.06
Probability of not dropouts=q=1-p=1-0.06=0.94
n=35
We use the probability mass function of binomial distribution, as there are only two possible outcomes for the given situation. If the individual is dropout or not a dropout.
P(X=x)= nCr x p^r x q^(n-r)
P(X=7)= 35C7x(0.06)^7x(0.94)^28
P(X=7)=6724520x(0.06)^7x(0.94)^28
P(X=7)=0.00332889
Therefore, the probability of exactly 7 of them are dropouts is 0.00332889.

For a set of five numbers,
the mode is 8
the median is 12
Work out one possible set of five numbers.
Step-by-step explanation:
mode = the number appearing the most often in the list of data.
median = the middle number. half of the other numbers are smaller, and the other half is larger.
so, we know one number already : 12 in the middle.
that gives us
_ _ 12 _ _
a good mode is when it has a real majority (e.g. every other number appears only once, but the mode number appears twice).
so, 8 should appear twice.
as 8 is smaller than 12, it can only be on the left side of 12.
that gives us
8 8 12 _ _
note we need 2 numbers larger than 12, but each appearing only once.
so, e.g.
8 8 12 13 14

The lateral surface area of cone A is equal to the lateral surface area of
cylinder B. This is true.
How to illustrate the information?Lateral area of cone is given by: πrl
where r is the radius and l is the slant height
Here r=r and l=2h
Hence, lateral area of cone A= π×r×2h = 2πrh
Lateral area of cylinder is given by: 2πrh
where r is the radius and h is the height
