Write a multiplication equation to show an equivalent fraction of 15 using fifteenths.​

Let's set up the cost constraint inequality.

x = number of large fish, some nonnegative integer

y = number of small fish, some nonnegative integer

8x = cost of just the large fish only

3y = cost of just the small fish only

8x+3y = total cost

The total cost must be $100 or smaller, so Alanna keeps to her budget.

We form the inequality 8x+3y ≤ 100 as the cost constraint.

Because x and y are nonnegative, this means x ≥ 0 and y ≥ 0

----------------

Now let's form the water constraint inequality.

x = number of large fish

y = number of small fish

2x = amount of water needed for the large fish only

0.5y = amount of water needed for the small fish only

2x+0.5y = total amount of water needed

This total must be 15 gallons or fewer.

2x+0.5y ≤ 15

Let's multiply both sides by 2 to make that 0.5 turn into a whole number.

2x+0.5y ≤ 15

2*(2x+0.5y) ≤ 2*15

4x+y ≤ 30

This represents the water constraint.

----------------

Here are the inequalities we found

8x+3y ≤ 100

4x+y ≤ 30

x ≥ 0

y ≥ 0

The first two items represent the cost constraint and water constraint in that order. The last two items make sure that x and y can't be negative.

Valid (x,y) solutions will be found in the shaded region of that system of inequalities. Points on the boundary are included in the shaded region due to the "or equal to" as part of each inequality sign.

Below is the graph of this system of inequalities. I used Desmos to make the graph. GeoGebra is another good choice. Let me know if you need to make the graph by hand rather than use technology.

The purple shaded region represents all possible (x,y) solutions.

For example, (5,5) is in that shaded region. I've marked it in the drawing below. This means x = 5 large fish and y = 5 small fish can be bought. Alanna will stick to her budget and she'll have enough water to go around.

On the other hand, (5,25) is NOT in the shaded region. This means Alanna cannot buy x = 5 large fish and y = 25 small fish (she'll either go over budget or she won't have enough water, or both happens).

The sample mean protein concentration obtained using the Bradford method for protein analysis is 1.00 mg/ml.

We must add together all the protein concentrations and divide the total by the number of observations in order to determine the sample mean for the protein concentrations acquired using the Bradford technique for protein analysis.

We have ten identical protein samples in this instance, and the measured protein concentrations are as follows:

Protein concentration (mg/ml) observations: 1: 1.02, 2: 0.98, 3: 0.99, 5: 1.01, 6: 0.97, 8: 1.00, 9: 1.03, and 10: 1.01.

We add up the protein concentrations and divide the total by the number of observations to determine the sample mean:

[tex](1.02 + 0.98 + 0.99 + 1.01 + 1.03 + 0.97 + 1.00 + 0.98 + 1.03 + 1.01) / 10[/tex] is the sample mean.

Therefore , the solution of the given problem of probability comes out to be the response is A 1/9.

The primary goal of the systems inside a procedure known as criteria is to determine the average possibility that a statement is true or that a specific occurrence will occur. Any value from 0 to 1, when 0 is frequently utilized to denote that something is likely and 1 is typically used to denote a level of confidence, can be used to represent chance. The chance that a specific event will occur is displayed in a probability diagram.

Here,

If a 6 is rolled on the first roll, the probability of spinning a number less than 5 on the second roll is 2/3,

since there are the four possible outcomes on the third roll that are less than 5 (rolling a 1, 2, 3, or 4) out of an overall of six possible outcomes (rolling any plenty from 1 to 6),

so the probability of a favorable outcome is 4/6, which simplifies to 2/3.

As a result, the likelihood that a 6 will be rolled on the first roll and a figure less than 5 will be rolled on the second roll is:

=> (1/6) x (2/3) = 1/9

Jabu's Monthly salary is of R27500.00, with an increase of R1 746.25 per month. Jabu's monthly increase is R1 746.25. The correct answer is option 3.

To find Jabu's previous monthly salary, we can use the formula:

Previous monthly salary = (Annual salary / 12)

Since Jabu's new annual salary is R330 000, his previous annual salary would be:

Previous annual salary = (New annual salary / 1.0635) = (R330 000 / 1.0635) = R310 020.10

Therefore, Jabu's previous monthly salary would be:

Previous monthly salary = (Previous annual salary / 12) = (R310 020.10 / 12) = R25 835.01

To find the monthly increase, we can subtract Jabu's previous monthly salary from his new monthly salary:

Monthly increase = (New monthly salary - Previous monthly salary) = (R27 618.38 - R25 835.01) = R1 783.37

Therefore, Jabu's monthly increase is R1 746.25 (rounded to the nearest cent).

Answer:

Step-by-step explanation:

We can use the fact that the ratio of the volumes of two similar solids is equal to the cube of their corresponding linear dimensions, also known as the volume-scale factor:

(volume of image) / (volume of original) = (linear dimension of image / linear dimension of original)^3

(40 cubic units) / (10 cubic units) = (linear dimension of image / linear dimension of original)^3

4 = (linear dimension of image / linear dimension of original)^3

Taking the cube root of both sides, we get:

(cube root of 4) = (linear dimension of image / linear dimension of original)

Simplifying, we have:

2 = (linear dimension of image / linear dimension of original)

Therefore, the linear dimensions of the image are two times greater than those of the original. Thus, the scale factor is 2.

The area of the shaded region of the circle is 63.24 ft²

We know that the area of a circle of radius R is given by the formula:

Area = pi*R²

Where pi = 3.14

If we have only a section of a circle defined by an angle θ, the area of that section will be:

area = (θ/360°)*3.14*R²

Here we know that the radius is 5 feet, and that AOB (the non-shaded part) is 70°, then we will have:

θ = 360° - 70° = 290°

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form and its energy of combustion is known very accurately (-26.43 kJ/g).

The calorimeter constant is -2873.5.

Determine the calorimeter constant of the calorimeter that had a temperature increase of 9.199 degrees Celsius when 3.500 g of benzoic acid was used.To determine the calorimeter constant, follow these steps:

Explanation:

1. Calculate the energy released by the benzoic acid combustion: Multiply the mass of benzoic acid by its energy of combustion.
Energy released = mass × energy of combustion
Energy released = 3.500 g × -26.43 kJ/g = -92.505 kJ

2. Convert the temperature increase to a change in energy: Multiply the temperature increase by the mass of benzoic acid.
ΔEnergy = temperature increase × mass of benzoic acid
ΔEnergy = 9.199°C × 3.500 g = 32.1965 J

3. Determine the calorimeter constant: Divide the energy released by the change in energy.
Calorimeter constant = Energy released / ΔEnergy
Calorimeter constant = -92.505 kJ / 32.1965 J

Note: We need to convert the units to be consistent, either to J or kJ.
1 kJ = 1000 J, so -92.505 kJ = -92505 J.

Calorimeter constant = -92505 J / 32.1965 J = -2873.5

The calorimeter constant is -2873.5.

The probability of the human Grandmaster winning one out of three games against the AI is approximately 0.243 or 24.3%.

Let's denote the probability of the human Grandmaster winning one game as p. Then the probability of the AI winning one game is 0.9, which means the probability of the human winning one game is 0.1. Since we want to calculate the probability of the human winning one game out of three, we can use the binomial distribution formula:

[tex]P(X=k) = (^n _k) \times p^k \times (1-p)^{(n-k)}[/tex]

Where:

P(X=k) is the probability of getting k successes in n trials

(n choose k) is the binomial coefficient, which is the number of ways to choose k successes from n trials

p is the probability of success in one trial

(1-p) is the probability of failure in one trial

k is the number of successes we are interested in (in this case, k=1)

n is the total number of trials (in this case, n=3)

Plugging in the values, we get:

P(X=1) = (3 choose 1) * 0.1^1 * 0.9^(3-1) = 3 * 0.1 * 0.81 = 0.243 or 24.3%

This means that there is a decent chance for the human to win at least one game, but it is still more likely for the AI to win all three games.

Part A is 8/13 of the whole

Part B is 5/13 of the whole

Step-by-step explanation:

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 40 + 25 = 65

Part A = 40 and Part B = 25 are numerators for each fraction.

The fractions are then:

40/65 and 25/65

Meaning:

Part A is 40/65 of the whole

Part B is 25/65 of the whole

Reducing the fractions, it is also true that:

Part A = 8/13 of the whole

Part B = 5/13 of the whole

a)the ratio of the heights of the pyramids is 5:3. b)the volume of the larger pyramid is 23.04 cm³.

what is volume  ?

Volume is a measure of the amount of space that a three-dimensional object occupies. It is usually measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³). The volume of an object can be calculated using different formulas depending on its shape.

In the given question,

a. Let the height of the smaller pyramid be h₁ and the height of the larger pyramid be h₂. Since the two pyramids are similar, their corresponding linear dimensions are in the same ratio as the areas of their bases. Therefore, we have:

(base area of smaller pyramid)/(base area of larger pyramid) = (linear dimension of smaller pyramid)² / (linear dimension of larger pyramid)²

Since the linear dimension is the height in this case, we can substitute the given ratio of the base areas to obtain:

25/9 = (h₁/h₂)²

Taking the square root of both sides, we get:

h₁/h₂ = 5/3

Therefore, the ratio of the heights of the pyramids is 5:3.

b. Since the volume of a pyramid is proportional to the cube of its height, we have:

(volume of smaller pyramid) / (volume of larger pyramid) = (h₁/h₂)³ = (5/3)³ = 125/27

Substituting the given volume of the smaller pyramid, we get:

108 / (volume of larger pyramid) = 125/27

Solving for the volume of the larger pyramid, we obtain:

volume of larger pyramid = (27/125) * 108 = 23.04 cm³ (rounded to two decimal places)

Therefore, the volume of the larger pyramid is 23.04 cm³.

The expression -5 + 28p9q5 - 12pq + 7 is equivalent to 7. Since all the terms except the last one contain variables, we can use algebra to solve for the value of the expression.

Algebra is a branch of mathematics which deals with the manipulation of equations, inequalities, and other mathematical expressions. Algebra is used to solve equations, simplify expressions, and model real-world problems.

To begin, we can add -5 and 7 to obtain 2. This means that the expression is now equal to 2 + 28p9q5 - 12pq. We can then simplify this expression by combining like terms.

Since 28p9q5 and -12pq are both products of the same variables, we can add them together. When we do so, we obtain 16p9q5, which means that the expression is now equal to 2 + 16p9q5.

Finally, we can simplify the remaining term by breaking down the product. We can divide 16 by 8 to obtain 2, and then divide 9 by 3 to obtain 3. This means that the expression is now equal to 2 + 2p3q5. Since there are no more terms to simplify, we can conclude that the answer is 2.
