The selling price of juice that costs a beverage company $0.75 to make with a 35% markup is $1.01.

What is markup?

Markup is the difference between the cost of a product or service and its selling price.

The cost of a product is the amount spent on making or buying the product.

The selling price is the amount for which the product is sold.

Therefore, when a company wants to make a profit, it applies a markup to the cost of the product to determine the selling price.

The markup represents the amount of money a company adds to the cost of a product to make a profit.

Here's how to solve the problem:

A beverage company sells juice in all the major restaurants. It costs the beverage company $0.75 to make each bottle of juice. The company uses a 35% markup. What is the selling price of the juice?

Markup = 35% of the cost

Price = cost + markup

Step 1: Find the markup

Markup = 35% of 0.75

Markup = 0.35 x 0.75

Markup = 0.26

Step 2: Find the selling price

Price = cost + markup

Price = 0.75 + 0.26

Price = 1.01

The selling price of juice that costs a beverage company $0.75 to make with a 35% markup is 1.01.

To find the values of the variables in similar polygons, we need more specific information about the problem.

Similar polygons have corresponding angles that are equal and corresponding sides that are proportional. However, without knowing any specific measurements or relationships between the sides and angles, it is not possible to determine the exact values of the variables. Therefore, we cannot provide a numerical answer without additional information.

In order to solve for the variables in similar polygons, we typically need either the ratio of corresponding side lengths or the measure of at least one angle. With this information, we can set up proportions and solve for the unknown variables. However, since the problem did not provide any measurements or ratios, we cannot proceed with finding specific values for the variables.

After 10 seconds, the snail is 14 inches away from Diana. Let's assume that Diana is at the origin (0,0) and the snail moves at a constant speed. Let's consider the snail is at point (x, y) and Diana is at the origin (0,0). The snail is moving away from Diana at a constant speed. It moves 2 inches in 4 seconds.

Then the distance traveled by the snail in 1 second is

= 2/4inches

= 0.5 inches.

So, the distance the snail travels from (0,0) in x seconds is 0.5x. After 3 seconds, the snail moves

= 0.5(3)

= 1.5 inches away from Diana, and its distance from her is 9 inches.

So, we have y = 9 + 0.5x. This is the equation for the snail's distance from Diana, y, as a function of time, x.

We can see that the equation y = 9 + 0.5x provides the snail's distance from Diana. Here, y is the distance between Diana and the snail and x is the current time. We can observe that the snail moves at a constant pace of 0.5 inches per second since the coefficient of x is equal to 0.5. The constant term in the equation is 9, which stands for the separation between Diana and the snail at the initial value of x, or 0, the starting point.

Therefore, we can infer that the distance between the snail and Diana, y, as a function of time, x, is represented by the equation y = 9 + 0.5x. The distance between Diana and the snail can be calculated at any time using this equation. The distance between Diana and the snail after 10 seconds, for instance, can be calculated using this equation.

For this,

we substitute x = 10 in the equation and get

y = 9 + 0.5(10)

= 14.

Therefore, after 10 seconds, the snail is 14 inches away from Diana.

Rob has (1/2) * x - $25.75 of his earnings left from this week. This is obtained by subtracting the amount spent on bills and the cost of the video game from his total earnings.

To find out how much of his earnings Rob has left, we need to calculate the portion he spent and subtract it from his total earnings.

Given that Rob spends 1/2 of his earnings on bills, he has 1 - 1/2 = 1/2 of his earnings remaining.

If Rob buys a video game for $25.75, we can subtract this amount from his remaining earnings.

Let's say Rob's total earnings for the week were x dollars.

Amount spent on bills: (1/2) * x

Amount spent on the video game: $25.75

Remaining earnings: x - [(1/2) * x + $25.75]

Simplifying the expression, we have:

Remaining earnings: x - (1/2) * x - $25.75

Remaining earnings: (1/2) * x - $25.75

So, Rob has (1/2) * x - $25.75 of his earnings left from this week.

To calculate the perimeter, add the lengths of sides AB, BC, and AC. The area can be found using Heron's formula. To find the angles, use the law of cosines.

1. **Perimeter and area of triangle ABC**

To find the perimeter and area of triangle ABC, we need to use the given information about its sides and angles.

Let's assume that side AB has a length of "a", side BC has a length of "b", and side AC has a length of "c". The given angles are angle A, angle B, and angle C.

The perimeter of a triangle is the sum of the lengths of its sides. Therefore, the perimeter P of triangle ABC is given by: P = a + b + c.

To find the area of triangle ABC, we can use Heron's formula, which states that the area A of a triangle with side lengths "a", "b", and "c" is given by: A = √(s(s - a)(s - b)(s - c)), where s is the semi-perimeter of the triangle, given by: s = (a + b + c) / 2.

Once we have calculated the area, we can use the law of cosines to find the measures of the angles. The law of cosines states that for a triangle with side lengths "a", "b", and "c", and opposite angles A, B, and C, the following relationships hold:

cos(A) = (b^2 + c^2 - a^2) / (2bc)

cos(B) = (a^2 + c^2 - b^2) / (2ac)

cos(C) = (a^2 + b^2 - c^2) / (2ab)

Using these formulas, we can calculate the measures of the angles A, B, and C.

To find the amount of the payment that goes towards interest at the 12th payment, you should multiply the balance at the 12th payment by the interest rate which is 8%.

The balance of the loan after 12 payments is $4159.90.

Thus the amount of the payment that goes towards interest at the 12th payment is:

4159.90 × 0.08 = $332.79

The principal amount paid at the 12th payment is the difference between the monthly payment of $187.80 and the amount of interest paid of $332.79.

The principal amount paid at the 12th payment

= $187.80 − $332.79

= −$144.99

The negative answer means that the amount paid is the interest.

To find the balance of the loan after the 35th payment, we will subtract the monthly payment from the balance after the 34th payment.

Therefore, the balance of the loan after the 35th payment is:

380.60 − 187.80 = $192.80

To find the amount of the payment that goes towards interest at the 35th payment, you should multiply the balance at the 35th payment by the interest rate which is 8%.

The balance after the 34th payment is $380.60, so the interest payment at the 35th payment is:

380.60 × 0.08 = $30.44

The principal amount paid at the 35th payment is the difference between the monthly payment of $187.80 and the amount of interest paid of $30.44.

The principal amount paid at the 35th payment

= $187.80 − $30.44

= $157.36

Therefore, the balance of the loan after the 35th payment is:

Given that y is inversely proportional to the square root of x. When x = 64, y = 4.Therefore, y∝1/√x We need to find the value of x when y = 8.Substitute the given values in the above equation and get:y∝1/√xx1/4= k where k is a constant.

the equation becomes y = k/√x Given that x = 64 and y = 4 ⇒ 4 = k/√64 = k/8⇒ k = 4 × 8 = 32Therefore, the equation becomes y = 32/√x Now, we need to find the value of x when y = 8. Substituting the given value of y in the above equation, we get:8 = 32/√x⇒ √x = 32/8 = 4⇒ x = (4)² = 16Hence, the value of x when y = 8 is 16.

The height of a cylinder with a volume of 440 cm³ and a diameter of 4 cm can be found using the formula for the volume of a cylinder and the relationship between the diameter and radius. The simplified expression of (a + 2b)(a^2 - 2ab - 4b^2) is a^3 - 6a^2b - 2ab^2 - 8b^3.

1. We are given the volume of the cylinder as 440 cm³ and the diameter as 4 cm.

2. The formula for the volume of a cylinder is V = πr²h, where V represents the volume, r represents the radius, and h represents the height.

3. To find the height, we need to determine the radius of the cylinder.

4. The diameter is given as 4 cm, and since the radius is half the diameter, the radius would be 2 cm (4 cm ÷ 2).

5. Substituting the known values into the volume formula, we have 440 cm³ = π(2 cm)²h.

6. Simplifying further, we get 440 cm³ = 4π cm²h.

7. Dividing both sides of the equation by 4π cm², we have h = 440 cm³ ÷ (4π cm²).

8. Using a calculator, we can evaluate the right side of the equation to get the numerical value of h.

  h ≈ 440 cm³ ÷ (4 * 3.14 cm²) ≈ 34.91 cm.

9. Therefore, the height of the cylinder with a volume of 440 cm³ and a diameter of 4 cm is approximately 34.91 cm.

we get:(x + 2) × x × (x - 1) = 8x³ + x² - 2x - 8 = 0Thus, the equation to model the volume of the compartment is 8x³ + x² - 2x - 8 = 0.

Given that

the compartment must be 2 meters longer than it is wide and its depth must be 1 meter less than its width. Let's assume the width of the compartment to be x meters.

Then, the length of the compartment would be (x + 2) meters as it is 2 meters longer than its width. And the depth of the compartment would be (x - 1) meters as its depth must be 1 meter less than its width.

Now, the volume of the compartment would be given by; V = l × w × d V = (x + 2) × x × (x - 1)As given, the volume of the compartment must be 8 cubic meters.

Hence, we get:(x + 2) × x × (x - 1) = 8x³ + x² - 2x - 8 = 0Thus, the equation to model the volume of the compartment is 8x³ + x² - 2x - 8 = 0.
