The value of the given expression √8/81 = 2√2/81.

The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. The equation a a = b is true if 'a' is the square root of 'b'. Every integer has two square roots, one of a positive value and one of a negative value, because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2.

Given that,

√8/81

We can write the value of √8 = √(2)(2)(2) = 2√2.

Thus, we have the value of √8/81 = 2√2/81.

Assuming a thickness of 1 millimeter for the cardboard, the amount of cardboard utilized to build the candy box is roughly 240 cubic centimeters.

Volume is the quantity of space in a 3D object in arithmetic. A fish tank, for example, is 3 feet long, 1 foot wide, and 2 feet tall. To calculate the volume, multiply the length by the breadth by the height, which is 3x1x2, which is six. As a result, the fish tank has a volume of 6 cubic feet.

Here,

Part A: To find the height of the base, we need to use the formula for the volume of a triangular prism:

V = Bh/2,

where B is the area of the base and h is the height.

We can assume the base of the triangular prism is an equilateral triangle with side length s. The area of an equilateral triangle can be found using the formula:

B = (s² * √(3))/4

We can use this formula to find the side length of the triangle:

s = √((4B)/(√(3)))

Substituting the known values, we have:

1200 = (s² * √(3))/2 * h

solving for h:

h = 1200 * 2 / (s² * √(3))

Substituting the value for s:

h = 1200 * 2 / ((√((4B)/(√(3)))² * √(3))

h = 1200 * 2 / (((4B)/(√(3))) * √(3))

h = 1200 * 2 / (4B)

h = 300 / B

We can find the value of B using the formula:

B = (s² * √(3))/4

Substituting the value for s:

B = (√((4B)/(√(3)))² * √(3))/4

B = (4B)/(3 * √(3))

B = 4B / (√(9))

B = 4B / 3

Solving for B:

B = 300 / h

So, the height of the base is approximately 30 cm.

Part B: To find the amount of cardboard used to make the candy box, we need to find the surface area of the triangular prism and multiply it by the thickness of the cardboard.

The surface area of a triangular prism can be found using the formula:

A = B + Bs + Bh

Where B is the area of the base, Bs is the area of the side of the triangular prism and Bh is the area of the top and bottom of the triangular prism.

We know that B = (s² * √(3))/4 and Bh = B, so

A = B + Bs + Bh = B + 2Bh = 2B + 2Bs

The surface area of the triangular prism is approximately 240 square centimeters.

Assuming the cardboard has a thickness of 1 millimeter, the amount of cardboard used to make the candy box is approximately 240 cubic centimeters.

Answer:

You got it wrong because you didn't distribute the 7 to the 3j.

Step-by-step explanation:

The answer should be 21j +70.

Answer:

In your original answer, you did not distribute the 7 to the 3j

Step-by-step explanation:

The distributive property basically states that the sum of any variables multiplied by a factor is equal to the sum of each product of every individual variable and the factor.

In short,

a(b+c) = ab + ac

or

x(y + w + z) = xy + xw + xz

or

9m + 9n = 9 (m+n)

Therefore, in order to solve 7(3j + 10)

you must multiply 7 by 3j and 7 by 10

(7 * 3j) + (7 * 10) = 21j + 70

Since 70 does not have the same terms as 21j (70 does not have j),

21j + 70 is in its most simplified form.

In your original answer, you didn't multiply the 3j by 7.

Mr. Cho received 3840 eggs in the beginning.

Let's assume that Mr. Cho received x eggs in the beginning.

In the morning, he sold 1/3 of the eggs, so he had 2/3 of the eggs left. Therefore, he had 2/3 x eggs left after the morning sales.

In the afternoon, he sold 320 eggs, so he had 2/3 × x - 320 eggs left at the end of the afternoon.

At the end of the day, he found that 1/4 of the eggs were not sold, which means that he had 3/4 of the eggs left. Therefore, we have:

3/4 × x = 2/3 × x - 320

Multiplying both sides by 12, we get:

9x = 8x - 3840

Simplifying, we get:

x = 3840

Therefore, Mr. Cho received 3840 eggs in the beginning.

A. The total profit earned is P(x) = -13600x - 24. B. The quantity at which the profit is maximized is 3.

Profit is a financial metric that represents the amount of money a business earns after subtracting its expenses and costs from its revenue. It is the positive difference between the revenue and the total cost of producing and selling a product or service.

Profit is a key indicator of the financial health of a business, as it reflects the ability of the business to generate income and manage its expenses effectively. A business that earns a profit is able to invest in growth opportunities, pay dividends to shareholders, and build a financial cushion for future expenses and emergencies.

Profit can be expressed as an absolute dollar amount or as a percentage of revenue, known as profit margin. Profit margin is calculated by dividing the profit by the revenue and multiplying the result by 100%. It represents the percentage of revenue that a business keeps as profit after paying its expenses and costs.

A. To find the total profit earned, we need to subtract the total cost from the total revenue:

P(x) = R(x) - C(x)

P(x) = 6800x - 24 - (1700 * 12x)

P(x) = 6800x - 24 - 20400x

P(x) = -13600x - 24

Therefore, the function that gives the total profit earned is P(x) = -13600x - 24.

B. To find the quantity at which profit is maximized, we need to find the value of x that maximizes the profit function P(x).

The profit function is a linear function with a negative slope (-13600), which means that the profit decreases as the quantity of jet-skis sold increases. Thereforte, the profit will be maximized at the lowest possible value of x.

We need to ensure that the value of x satisfies the constraints of the problem. The quantity x represents the number of jet-skis sold, so it must be a positive integer.

The total cost function is C(x) = 1700 * 12x, which means that the fixed cost is $20,400 (1700 * 12). This fixed cost must be covered by the revenue from selling the jet-skis.

The revenue from selling one jet-ski is R(x) = 6800x - 24. To cover the fixed cost, we need to find the value of x that satisfies the following inequality:

6800x - 24 ≥ 20400

Simplifying this inequality, we get:

6800x ≥ 20424

x ≥ 3

Therefore, the quantity must be at least 3 for the profit to cover the fixed cost.

Since x must be a positive integer, the value of x that maximizes the profit is 3.

To confirm this, we can calculate the profit at x = 2 and x = 3:

P(2) = -13600(2) - 24 = -27224

P(3) = -13600(3) - 24 = -40824

We can see that the profit is greater when x = 3, so the quantity at which the profit is maximized is 3.

Step-by-step explanation:

The money loaned at 9% annual interest was 1500 and the money loaned at 11% annual interest was 19000.

Let the amount of money loaned at 9% be x

the amount of money loaned at 11% be y

According to the question,

Total money loaned = 20,500

Thus the equation formed is,

x + y = 20,500 ------ (i)

Simple interest is calculated by

I = P * r * t

where I is the simple interest

r is the rate of interest

t is the time

Thus, the interest on x = 0.09x

the interest on y = 0.11y

Total interest gained = 2,225

Thus the equation formed is,

0.09x + 0.11y = 2225 -------(ii)

Multiply (i) by 0.09

0.09x + 0.09y = 1845

Subtract the above from (ii)

0.02y = 380

a) the estimated yearly increase in the average atmospheric concentration of carbon dioxide is 1.8 ppm.

b) C = 1.8x + 310 This equation represents the mathematical model that estimates the average atmospheric concentration of carbon dioxide, C, in ppm, x years after 1950.

c) if the trend shown by the data continues, the projected average atmospheric concentration of carbon dioxide in the year 2030 would be approximately 454 ppm.

a. To estimate the yearly increase in the average atmospheric concentration of carbon dioxide, we can look at the difference between consecutive data points.

From 1950 to 2000, the concentration increased from 310 ppm to 400 ppm. So, in 50 years, the increase was 400 ppm - 310 ppm = 90 ppm.

To find the yearly increase, we divide this by the number of years: 90 ppm / 50 years = 1.8 ppm per year.

Therefore, the estimated yearly increase in the average atmospheric concentration of carbon dioxide is 1.8 ppm.

b. To write a mathematical model that estimates the average atmospheric concentration of carbon dioxide in parts per million (ppm), x years after 1950, we can use a linear equation.

Let C represent the average atmospheric concentration of carbon dioxide in ppm, and x represent the number of years after 1950.

Based on the given data, we can assume a linear relationship between time (x) and carbon dioxide concentration (C). We'll use the point-slope form of a linear equation:

C - 310 = m(x - 0)

Where 310 is the concentration in 1950, and the slope m represents the yearly increase in ppm.

Using the yearly increase we estimated in part a (1.8 ppm per year), the equation becomes:

C - 310 = 1.8x

Simplifying, we find:

C = 1.8x + 310

This equation represents the mathematical model that estimates the average atmospheric concentration of carbon dioxide, C, in ppm, x years after 1950.

c. To project the average atmospheric concentration of carbon dioxide in the future, we can use our mathematical model from part b.

Assuming the trend shown by the data continues, we can substitute the desired year into the equation C = 1.8x + 310, where x represents the number of years after 1950.

For example, if we want to project the concentration in the year 2030 (80 years after 1950), we substitute x = 80 into the equation:

C = 1.8(80) + 310

C = 144 + 310

C = 454

Therefore, if the trend shown by the data continues, the projected average atmospheric concentration of carbon dioxide in the year 2030 would be approximately 454 ppm.
