Answer:
14 and 35 I believe.
Since the GCF of 14 and 35 is 7, the LCM is 70 (14×5 and 35×2), they both have 2 digits, and one is even (14) and the other is odd (35).
I hope this helped!
The mystery pair would be required for numbers 14 and 35.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What is Prime Factorization?Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.
We need to write 70 as the product of its prime factors, which is 70.
⇒ 2 × 5 × 7
14 × 5 and 35 × 2
Given that the GCF of the mystery pair is 7
And the LCM of the mystery pair is 70.
Here the GCF of 14 and 35 would be 7
As per the given condition,
The required numbers in the pair have two digits,
Therefore, the even number is 14, and the odd is 35.
Hence, the mystery pair would be required for numbers 14 and 35.

Most of the numbers we know, and work with, are Real Numbers. The Real Number System includes counting numbers, fractions, terminating decimals, positive numbers, negative numbers, zero, repeating decimals, never ending and non-repeating decimals, numbers that are expressed as radicals, and even pi (π).
The natural numbers are the set of counting numbers
• There are infinitely many numbers in a set of numbers.
• The natural numbers are "closed" under addition and multiplication.
The addition of two natural numbers creates another natural number.
The multiplication of two natural numbers creates another natural number.
closed under addition and multiplication.
BUT ...
The subtraction of two natural numbers does NOT necessarily create another natural number
The division of two natural numbers does NOT necessarily create another natural number
The whole numbers are the set of counting numbers (natural numbers) along with zero
• There are infinitely many numbers in this set of numbers.
• The set of whole numbers is "closed" under addition and multiplication.
Integers:
• The integers are the set of all of the natural numbers,
plus their additive inverses and zero
• The integers are "closed" under addition, multiplication and subtraction,
but NOT under division
Rational Numbers:
• The rational numbers are the set of numbers which can be expressed as a ratio
(a fraction) between two integers.
• Integers are rational numbers since 5 can be written as the fraction 5/1.
• Decimals which terminate are rational numbers.
• Decimals which have a repeating pattern are rational numbers. 1/3 = 0.3333333...
• The rational numbers are "closed" under addition, subtraction, and multiplication. Under division, we run into the problem of division by 0, which makes the statement that "the rationals are closed under division" false. Some texts state that "the rationals are closed under division as long as the division is not by zero" which is a true statement.
Irrational Numbers:
The irrational numbers are the set of number which can NOT be written as a ratio (fraction).
• Decimals which never end nor repeat are irrational numbers.
• Irrational numbers are "not closed" under addition, subtraction, multiplication or division.
• Examples of irrational numbers: rad2, π
This is figured out by first figuring out that:
√(√(i)) = [tex]i^{1/4\\}[/tex]
Let [tex]\sqrt{i}[/tex] be a + b[tex]i[/tex].
Square both sides to get [tex]i[/tex] = (a + b[tex]i[/tex])(a + b[tex]i[/tex])
So, [tex]i[/tex] = a² - b² + 2ab[tex]i[/tex]
a² - b² is the real part. The real part is 0.
0 + [tex]i[/tex] = a² - b² + 2ab[tex]i[/tex]
a² - b² = 0
[tex]i[/tex] = 2ab[tex]i[/tex]
2ab = 1
ab = 1/2
b = 1/2a
Now, since a² - b² = 0,
a² - (1/2a)² = 0
a² - 1/(4a²) = 0
[tex]\frac{(4a^{4}-1 )}{4a^{2} }[/tex] = 0
That means the numerator MUST be 0.
[tex](4a^{4}-1 )}[/tex] = 0
[tex]4a^{4}[/tex] = 1
[tex]a^{4}[/tex] = 1/4
a = ± [tex]\frac{1}{\sqrt{2} }[/tex]
if a = [tex]\frac{1}{\sqrt{2} }[/tex] , then b = [tex]\frac{1}{\sqrt{2} }[/tex]
If a = -[tex]\frac{1}{\sqrt{2} }[/tex] , then b = -[tex]\frac{1}{\sqrt{2} }[/tex]
So, it's either a = -[tex]\frac{1}{\sqrt{2} }[/tex] and b = -[tex]\frac{1}{\sqrt{2} }[/tex] , or a = [tex]\frac{1}{\sqrt{2} }[/tex] and b = [tex]\frac{1}{\sqrt{2} }[/tex]
That's why sqrt(i) =0.707106781 + 0.707106781i, or sqrt(i) = -0.707106781 - 0.707106781i

A magic carpet is made with three colors of yarn. The ratio of each color in the carpet is shown below: 10 parts gold yarn 7 parts bronze yarn 3 parts silver yarn The magic carpet is made with a total of 150 meters of yarn. How much silver yarn is in the magic carpet?
Answer:
There are 22.5 meters of silver yarn
Step-by-step explanation:
Gold yarn : bronze yarn : silver yarn
10 : 7 : 3
Gold yarn = 10
bronze yarn = 7
silver yarn = 3
Total ratio = 20
Total meters = 150 meters
How much silver yarn is in the magic carpet?
Quantity of silver yarn in the carpet = silver yarn ratio / Total ratio × total meters of yarn
= 3 / 20 × 150
= 450 / 20
= 22.5 meters
There are 22.5 meters of silver yarn
Bronze yarn = bronze yarn ratio / Total ratio × total meters of yarn
= 7 / 20 × 150
= 1,050 / 20
= 52.5 meters
Bronze yarn = 52.5 meters
Quantity of gold yarn in the carpet = gold yarn ratio / Total ratio × total meters of yarn
= 10 / 20 × 150
= 1500 / 20
= 75 meters
Gold yarn = 75 meters

What is a Mineral Formation?Minerals grow under a wide variety of geologic circumstances. There are probably more ways to produce minerals than there are different types of minerals. Minerals can occur as a result of volcanic gases, sediment formation, oxidation, magma crystallization, or saline fluid deposition, to name a few.
As per the question,
A. Dissolved substances crystallize on the bottom of a lake as
dolomite is an example of a way a mineral can form.

You are thinking of withdrawing all your funds; $45,000 from your 401 (k) at age 54. The normal tax rate for you would be 28%. The rules for withdrawing funds before the age of 59 1/2 is a 10% penalty. How much would you save if you waited until age 59 1/2?
Until the age of [tex]59.5[/tex] years, the amount saved from the withdrawal of funds is [tex]\$3,600.[/tex]
Used the concept of tax which states that,
A tax is an obligatory payment made by the taxpayer to the government in respect of the income earned in the previous year.
Given values:
Amount of funds: [tex]\$45,000[/tex]
Normal tax rate: [tex]20\%[/tex]
Penalty rate at [tex]59.5[/tex] years: [tex]10\%[/tex]
Step-1; Computation of after-tax amount paid at 54 years:
[tex]A_1= \text{Amount of funds} \times (1 - \text{Tax rate})[/tex]
[tex]= \$45,000 \times (1 - 0.2)[/tex]
[tex]= \$36,000[/tex]
Step-2; Computation of after-tax amount paid at 59.5 years:
[tex]A_2 = \text{Amount of funds} \times (1 - \text{Tax rate}) (1 - \text{Penalty rate})[/tex]
[tex]= \$45,000 \times (1 - 0.20) \times (1 - 0.10)[/tex]
[tex]= \$32,400[/tex]
Step-3; Computation of the amount saved;
[tex]\text{Amount saved} = A_1 - A_2\\= \$36,000 - \$32,400\\= \$3,600[/tex]
Therefore, the amount [tex]\$3,600.[/tex] was saved with the amount of [tex]\$36,000[/tex] paid-in [tex]54[/tex] years and the amount of [tex]\$32,400[/tex] paid-at [tex]59.5[/tex] years.

Frederick is training for a triathlon and wants to focus on swimming this week. He can swim 25 yards in 23 seconds. He set up a proportion to determine how long it would take him to swim 175 yards at this rate. Which proportions can be used to determine how long it would take him to swim 175 yards?
Answer:
161secsStep-by-step explanation:
If Frederick can swim 25 yards in 23 seconds, then:
25 yards = 23 seconds
To determine how long it will take him to swim 175yards, we will say:
175 yards = x
Equating both expression:
25 yards = 23 seconds
175 yards = x
Cross multiply
25x = 23*175
25x = 4025
Divide both sides by 25
25x/25 = 4025/25
x = 161 secs
This means that it will take Frederick 161 secs to swim 175 yards

A three-digit personal identification number is chosen using the digits 1–9. The digits cannot be repeated. What is the approximate probability that the first digit will be 6? 0.00595 0.03571 0.11111 0.66667
Answer: C
Step-by-step explanation:it’s the 3rd ans on edge
The question is an illustration of probability, and the approximate probability that the first digit will be 6 is (c) 0.11111
How to determine the probability?The number of digits in the pin = 3
Given that each digit cannot be repeated, the total number of pin is:
Pin = 9 * 8 * 7
Evaluate
Pin = 504
If the first digit is 6, the number of pins is:
First digit6 = 1 * 8 * 7
First digit6 = 56
So, the probability that the first digit is 6 is:
P = 56/504
Evaluate
P = 0.1111
Hence, the approximate probability that the first digit will be 6 is (c) 0.11111
