Answer:

No only variable on both sides have no solution

Step-by-step explanation:

Then you can get,

for example x=x

or,

y=y

Answer:

Step-by-step explanation:

A. Every equation with variables on both sides has no solution.​ However, it is also possible for an equation with the variable on only one side to also have no solution.

B. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. This means that if an equation has no​ solution, then the variable must appear on both sides.

C. Any equation can have one​ solution, infinitely many​ solutions, or no solutions. This does not depend on whether the variable appears on only one side or on both sides.

D. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. By​ contrast, an equation with variables on both sides always has no solution or infinitely many solutions.

b-1. The profit on a monthly volume of 61,000 is $3000

b-2. The Profit on a monthly volume of 87,000 units is $8,200

c. Volume is needed to obtain a profit of $16,000 per month is 126,000units

d. Volume is needed to provide a revenue of $23,000 per month is 25,556 units.

Proper production is pivotal in making the the business successful. There are many factors to consider to make sure that the production is at maximum efficiency. Example factors include the cost of materials, the quantity to produce, the selling price of the product, and the fixed and variable cost of the product.

a. There should be 46,000 units in order to break even.

The break-even formula is:

Break even = Fixed cost / Price - Variable cost

                   = 9,200/ 0.9 - 0.7

                   = 46,000

Volume per month = 46,000 units

b-1. The profit realized is $3,000 when monthly volume is 61,000 units.

The formula is:

Profit = Price × quantity - (fixed cost - variable cost × quantity)

Profit = 0.9 × 61,000 - (9,200 + 0.7 × 61,000)

Profit = 54,900 - 51,900

Profit = 3,000

b-2. The profit realized is $8,200 when monthly volume is 87,000 units.

Profit = 0.9 × 87,000 - (9,200 + 0.7 × 87,000)

Profit = 8,200

c. The monthly volume when profit is $16,000 is 126,000 units.

The formula is : Quantity = \(\frac{Profit+fixed cost}{Price-variable cost}\)

Quantity = \(\frac{16,000+9,200}{0.9-0.7}\)

Quantity = 126,000

d. The volume needed to provide a revenue of $23,000per month is 25,556 units.

The distance between the final positions of the two people is 13 meters. So, the correct answer is option 2.

To find the distance between the final positions of the two people, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, one person walks 5 meters to the east, and the other person walks 12 meters to the north. This forms a right triangle, with the person who walked to the east representing the horizontal leg of the triangle and the person who walked to the north representing the vertical leg of the triangle.

Using the Pythagorean theorem, we can calculate the distance between the final positions as follows:

\(Distance^2 = (5^2) + (12^2)\\Distance^2 = 25 + 144\\Distance^2 = 169\)

Taking the square root of both sides, we find:

Distance = √169

Distance = 13

Therefore, the distance between the final positions of the two people is 13 meters. So, the correct answer is option 2.

To determine the missing amounts in each situation, let's analyze the given information.Situation a: Supplies available-prior year end: $3,578

Supplies purchased during the current year: $675

Total supplies available: $4,725

To find the missing amount, we can subtract the known values from the total supplies available:

Missing amount (Situation a) = Total supplies available - (Supplies available-prior year end + Supplies purchased during current year)

                           = $4,725 - ($3,578 + $675)

                           = $4,725 - $4,253

                           = $472

Therefore, the missing amount in Situation a is $472.

Situation b:

The missing amount is already provided in the question as $12,165.

Situation c:

Supplies available-current year-end: $3,041

Supplies expense for the current year: (unknown)

To find the missing amount, we need to determine the supplies expense for the current year. However, based on the given information, there is no direct indication of the supplies expense. It is not possible to determine the missing amount in this situation without additional information.

Situation d:

Supplies available-current year-end: $5,400

Supplies expense for the current year: $24,257

To find the missing amount, we can subtract the known supplies expense from the supplies available at the current year-end:

Missing amount (Situation d) = Supplies available-current year-end - Supplies expense for the current year

                           = $5,400 - $24,257

                           = -$18,857 (negative value indicates a loss)

Therefore, the missing amount in Situation d is -$18,857 (indicating a loss of $18,857).

In summary, we were able to determine the missing amounts in Situations a and d, while Situations b and c already provided the missing amounts in the question.

The formula for the exponential function is V = 5000 (2)^(−t/4).

What is an exponential function?

A function whose value is a constant raised to the power of an argument is called an exponential function.

Here, we have

The value of an item initially worth $5000 loses half its value every 5 years.

V = V₀eˣⁿ

At t = 0,V = V₀

So, V = 5000eˣⁿ

At t = 4,V = V₀/2 = 2500

Substituting these into our equation, we have

5000e^(4k) = 2500

e^(4k) = 12

4k = −ln2

k = −ln2/4

Finally, we have our equation

V = 5000e^(−tln2/4 )

V = 5000(e^ln2)^(−t/4)

V = 5000 (2)^(−t/4)

Hence, the formula for the exponential function is V = 5000 (2)^(−t/4).

Using the given natural abundances of titanium-46, titanium-47, and titanium-48, we find that the average atomic mass of titanium on this planet is approximately 46.4 amu.

To calculate the average atomic mass of titanium on another planet, we need to consider the natural abundances of its isotopes. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and summing up these values.

Let's assume that the three isotopes of titanium on this planet are denoted as titanium-46, titanium-47, and titanium-48. The natural abundances of these isotopes are given as follows:

Isotope Natural Abundance

Titanium-46 70%

Titanium-47 20%

Titanium-48 10%

To calculate the average atomic mass, we multiply the mass of each isotope by its relative abundance and sum up these values. The atomic masses of titanium-46, titanium-47, and titanium-48 are approximately 46.0 amu, 47.0 amu, and 48.0 amu, respectively.

Average Atomic Mass of Titanium:

(46.0amu×70%)+(47.0amu×20%)+(48.0amu×10%)

=(32.2amu)+(9.4amu)+(4.8amu)

=46.4amu

Therefore, the average atomic mass of titanium on this planet is approximately 46.4 atomic mass units (amu).

The fraction of the cookies do they still need to made after Cameron and Lindsey made 80 cookies is 1/2.

Fractions are referred to as the components of a whole in mathematics. A single thing or a collection of objects might be the entire. When we cut a slice of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Roman. "Fractus" means "broken" in Latin.

The fraction was expressed verbally in earlier times. It was afterwards presented in numerical form. A piece or sector of any quantity is another name for the fraction.

Total cookies to be made is 160

Out of which Cameron made 2/5 of the cookies so,

2/5 x 160 = 64 cookies are made by Cameron

Lindsey made 16 cookies

So total cookies that still need to be made is,

The fundamental theorem of arithmetic states that every natural number greater than 1 can be written as a product of primes. Using strong induction, we can prove this.

Let's proceed with the strong induction proof. We start by considering the base case, where m = 2. Since 2 is prime, it can be written as a product of primes itself.

Next, we assume that for all natural numbers k such that 2 ≤ k ≤ m, the statement holds true, i.e., k can be expressed as a product of primes. Now, we aim to prove that m+1 can also be expressed as a product of primes.

We know that m+1 is either prime itself or composite. If m+1 is prime, then it can be written as a product of a single prime, satisfying the theorem.

On the other hand, if m+1 is composite, it can be written as a product of two positive integers a and b, where 2 ≤ a ≤ b ≤ m. Since a and b are both less than or equal to m, we can apply the inductive hypothesis to express a and b as products of primes. Therefore, we can write m+1 as a product of primes by combining the prime factorizations of a and b.

By strong induction, we have shown that for any natural number m greater than 1, it can be expressed as a product of primes. This completes the proof of the fundamental theorem of arithmetic.
