Applying the rules of exponents, the value of n in the equation given is calculated as: n = 8.

The product rule of exponents says that when the base are the same, add their exponents together.

For example, m × m² = m^(1 + 2) = m³.

The exponents are 1 and 2. The expression has similar base of m. Therefore, to multiply m and m² together, we would simply add their exponents together while the final result will be the same base.

Also, the negative rule of exponents states that we subtract their exponents if they have he same base.

For example:

m³/m² = m³ ÷ m² = m^(3 - 2) = m.

Given the equation:

[tex]\frac{4^3 \times 8^2}{2^n} = 2^4[/tex]

Simplify the bases to make all equal

= [tex]\frac{2^{(2)(3)} \times 2^{(3)(2)}}{2^n} = 2^4[/tex]

= [tex]\frac{2^{6} \times 2^{6}}{2^n} = 2^4[/tex]

Apply the product rule and the negative rule of exponents to find the value of n in tye equation:

[tex]2^{(6 + 6 - n)} = 2^4\\\\2^{(12 - n)} = 2^4\\\\[/tex]

The bases will cancel each other:

12 - n = 4

Subtract 12 from both sides

12 - n - 12 = 4 - 12

-n = -8

Divide both sides by -1

n = 8

Income is a total that includes any wages, salaries, profits, interest payments, rent, or other forms of earnings received in a calendar year for families and individuals in the United States, as defined by tax law. Gross income less taxes and other deductions (such as required pension payments) is a common definition of discretionary income and is frequently used as a benchmark to assess the wellbeing of taxpayers.

The idea may include the accumulation of both monetary and non-monetary consumption capacity, with the former (monetary) serving as a stand-in for total income in the field of public economics.

The amount of money would be $1115.45 the zoo makes selling the waste that day.

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

They charge farmers $5 per pound for the daily feces from the elephants. If an elephant's daily waste production is at or below the 10th percentile for the distribution of waste which is given in the question.

To determine the amount of money would the zoo make selling the waste that day.

P(z ≤ z₀) = 0.1

z₀ = -1.28

⇒z₀ =(x₀ -μ ) / σ

Substitute the values and solve for x₀,

⇒ -1.28 =(x₀ -250 ) / 21

⇒x₀ = (-1.28)×21 - 250

⇒x₀ = 223.09

So the amount of money would be as :

⇒ 223.09 × 5

⇒ 1115.45

Therefore, the amount of money would be $1115.45 the zoo makes selling the waste that day.

Answer:

72,000 yards

Step-by-step explanation:

The scale factor can be found by doing:

[tex]240 \div 4 = 60[/tex]

This means that 60 is the scale factor. You can apply the scale factor to the length of the rectangular building, meaning that the length of the actual building is:

[tex]5 \cdot 60 = 300[/tex] yards

So, if the building is 240 yards wide, and 300 yards long. You can find the area of the actual building just like any other rectangle using:

[tex]A = l \cdot w[/tex]

(Area = length * width)

So, the final answer is:

[tex]A = 300 \cdot 240\\ A= 72,000[/tex]

This means that the area of the actual building is 72,000 yards.

Using the exterior angle of a polygon theorem, the value of the missing angle is 58°

From the question, we are to calculate the value of the missing angle.

From the given information, the missing angle is (3x -2)°.

To calculate the value of the missing angle,

First, we will determine the value of x

From the Exterior angle of a polygon theorem, we can write that

90° + (3x + 12)° + (4x - 10)° + (3x - 2)° + 70° = 360°

(3x + 12)° + (4x - 10)° + (3x - 2)° = 360° - 70° - 90°

3x° + 12° + 4x° - 10° + 3x° - 2° = 200°

10x° = 200° + 2° + 10° - 12°

10x° = 200°

x = 200/10

x = 20

The missing angle is (3x -2)°

Substitute the value of x

(3(20) -2)°

= (60 -2)°

= 58°

Thus,

The missing angle measure is 58°

Based on the number of bushels that the farmer has to sell, the equation that represents the total change in the number of bushels after seven days is 220 - 15⁵/₈(7).

The farmer has a total of 220 bushels of wheat to sell and then sells about 15⁵/₈ every day.

After 7 days, the total change in the number of bushels would be:

= Total bushels to be sold - Bushels of wheat already sold

= Total bushels to be sold - (Number of bushels sold per day x Number of days)
= 220 - 15⁵/₈(7)

= 110 bushels of wheat

The quadratic equation that has roots (-1 - √2)/3 and (-1 + √2)/3 is:

x² + (2/3)x - 1/9 = 0

We have been given the roots of quadratic equation.

(-1 - √2)/3 and (-1 + √2)/3

We need to find the quadratic equation.

Since (-1 - √2)/3 and (-1 + √2)/3 are roots, (x - (-1 - √2)/3) and (x - (-1 + √2)/3) must be the factors of the quadratic equation.

So, the required quadratic equation would be,

(x - (-1 - √2)/3) * (x - (-1 + √2)/3) = 0

x[x - (-1 + √2)/3) ] - ( (-1 - √2)/3) [x - (-1 + √2)/3] = 0

x² - x(-1 + √2)/3 - x(-1 - √2)/3 + [(-1 - √2)(-1 + √2)]/9 = 0

x² - x(-2/3) + (1 - 2)/9 = 0

x² + (2/3)x - 1/9 = 0

The time taken by Peter to arrange the chairs all by himself is 10/3 minutes.

Given that :-

Katrina can arrange the chairs in the classroom in 5 minutes.

One day peter helped her and took both of them 2 minutes to arrange the chairs.

We have to find the time taken by Peter to arrange the chairs all by himself.

LCM (5,2) = 10

Let the total work of arranging the chairs is of 10 units.

We know that,

Efficiency of a person = Total Work/Time taken by person

Hence,

Efficiency of Katrina = 10/5 = 2 units

Efficiency of Katrina + Efficiency of Peter = 10/2 = 5 units

The definition for the function is y = {-2x +1   x < 1 ; -x + 2   x ≥ 1. The correct option is b.

From the question, we are to determine the equation for the function

First, we will determine the equation for when x < 1

Picking the points (-1, 3) and (0, 1)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

(y - 3) / (x - -1) = (1 - 3) / (0 - -1)

(y - 3) / (x + 1) = -2 / (0 + 1)

(y - 3) / (x + 1) = -2 / 1

(y - 3) / (x + 1) = -2

y - 3 = -2(x + 1)

y - 3 = -2x - 2

y = -2x - 2 + 3

y = -2x + 1

Thus,

When x < 1, the function is y = -2x + 1

Now, determine the equation for when x ≥ 1

Picking the points (1, 1) and (2, 0)

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

(y - 1) / (x - 1) = (0 - 1) / (2 - 1)

(y - 1) / (x - 1) = -1 / 1

(y - 1) / (x - 1) = -1

y - 1 = -1(x - 1)

y - 1 = -x + 1

y = -x + 1 + 1

y = -x + 2

Thus,

When x ≥ 1, the function is y = -x + 2
