Alanna goes to the pet store to buy fish for her new 15-gallon fish tank. Each large fish costs $8 and requires 2 gallons of water. Each small fish costs $3 and requires 0.5 gallon of water. She has $100 to spend on fish at the pet store. Which combinations of large and small fish can Alanna purchase for her fish tank?

Answers

Answer 1

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).

An environmental agency frequently samples the water in a region to ensure that the levels of a certain contaminant do not exceed 30 parts per billion (ppb). From 12 randomly selected samples of the water, the agency constructed the 99 percent confidence interval (22.5, 28.7). Assuming all conditions for inference are met, which of the following is a correct interpretation of the interval? A For all water in the region, 99 percent of the water contains a level of the contaminant between 22.5 ppb and 28.7 ppb. B We are 99 percent confident that the mean level of the contaminant in the sample is between 22.5 ppb and 28.7 ppb. We are 99 percent confident that the mean level of the contaminant in all the water in the region is between 22.5 ppb and 28.7 ppb. D There is a 0.99 probability that the mean level of the contaminant in the sample is between 22.5 ppb and 28.7 ppb. E There is a 0.99 probability that the mean level of the contaminant in all the water in the region is between 22.5 ppb and 28.7 ppb.

Answers

The correct interpretation of the 99 percent confidence interval (22.5, 28.7) is B: We are 99 percent confident that the mean level of the contaminant in the sample is between 22.5 ppb and 28.7 ppb.

This does not indicate that the mean level of the contaminant in all the water in the region is necessarily between 22.5 ppb and 28.7 ppb.

Confidence intervals provide an estimate of the population mean based on a sample. In other words, they indicate the range of values that are likely to include the true mean of the population. Therefore, the interval (22.5, 28.7) indicates that we are 99 percent confident that the mean of the sample (which is used to estimate the true population mean) lies between 22.5 ppb and 28.7 ppb. However, this does not guarantee that the true population mean (i.e., the mean of all the water in the region) lies between 22.5 ppb and 28.7 ppb.

The other answers are incorrect because they do not reflect the fact that the interval provides an estimate of the population mean based on a sample.

Answer A is incorrect because it states that all of the water in the region must contain a level of the contaminant between 22.5 ppb and 28.7 ppb, which is not necessarily true.

Answer D is incorrect because it states that there is a 0.99 probability that the mean of the sample is between 22.5 ppb and 28.7 ppb, when in reality the interval indicates that we are 99 percent confident that the mean of the sample is between 22.5 ppb and 28.7 ppb. Finally,

Answer E is incorrect because it states that there is a 0.99 probability that the true population mean (i.e., the mean of all the water in the region) is between 22.5 ppb and 28.7 ppb, which is not necessarily true.

In summary, the correct interpretation of the 99 percent confidence interval (22.5, 28.7) is that we are 99 percent confident that the mean level of the contaminant in the sample is between 22.5 ppb and 28.7 ppb.

In this diagram, F represents the set of students who study French, G represents the set of students who study German, and B represents the set of students who study both French and German.

The information given tells us that 13 students study French, 5 study only German, and 6 study both French and German. Therefore, we can place 13 in the region for F, 5 in the region for G, and 6 in the overlapping region for B.

Answer:

f(3) = 3^3 + 6(3)^2 - 9(3) - 54

      = 27 + 54 - - 27 - 54 = 0

So (x - 3) is a factor.

f(-3) =  3^-3 + 6(-3)^2 - 9(-3) - 54

Step-by-step explanation:

x - y = 11 → (1)

2x + y = 19 → (2)

adding (1) and (2) term by term will eliminate y

(x + 2x) + (- y + y) = 11 + 19

3x + 0 = 30

3x = 30 ( divide both sides by 3 )

x = 10

substitute x = 10 into either of the 2 equations and solve for y

20 + y = 19 ( subtract 20 from both sides )

As we can see, a right-angled triangle results.

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two sides that make up the right angle is equal to the square of the hypotenuse. This can be expressed mathematically as a^2 + b^2 = c^2, where a and b are the two sides that make up the right angle, and c is the hypotenuse.

Use Pythagoras's principle.

c = √a² + b²

The distance in the Hypotenuse in our case is now.

c = √(70)² + (180)²

c = √4900 + 32400

c = √37,300

Answers

The percentage is 42% of the population is heterozygous for the recessive genetic disorder.

To determine the percentage of the population that is heterozygous for a recessive genetic disorder occurring in 9 percent of the population,

follow these steps:

1. Identify the frequency of the recessive allele (q) by taking the square root of the 9 percent occurrence (0.09). The square root of 0.09 is 0.3.

2. Calculate the frequency of the dominant allele (p) using the equation p = 1 - q. In this case, p = 1 - 0.3 = 0.7.

3. Determine the percentage of the population that is heterozygous using the equation 2pq. In this case, 2(0.7)(0.3) = 0.42 or 42%.

So, 42% of the population is heterozygous for the recessive genetic disorder.

Two streets form an intersection. ∠C and ∠D are vertical angles. If the measure of ∠C is (x + 16°) and the measure of ∠D is (4x − 5⋅).What is the measure of ∠D?

2.75°



23°

33.8°

Answers

Answer:

the measure of ∠D is 8°.

Step-by-step explanation:

Since ∠C and ∠D are vertical angles, they have equal measure. So we can set their measures equal to each other and solve for x:

x + 16° = 4x - 5°

6x = 21°

x = 3.5°

Now we can find the measure of ∠D:

∠D = 4x - 5°

∠D = 4(3.5°) - 5°

∠D = 8°

Therefore, the measure of ∠D is 8°.

The expression for the total amount of shoes for both people is 4X + 2.

What is another word for total cost?

As a result, total cost is the sum of fixed and variable costs, or TC = FC + VC = Kr+Lw.

Say Person 1 owns X pairs of shoes. So, Person 2 has two to three times as much as Person 1. This can be said as follows:

Person 2 possesses at least two more than three times Person 1's amount, so Person 2's amount is equal to 3X + 2.

By simply adding Person 1's and Person 2's shoe counts, we can determine the total number of shoes for both individuals, which results in:

Total equals the sum of the amounts given by Persons 1 and 2.

When we replace the value of Person 2's contribution, we obtain:

Amount total = X + (3X + 2)

If we simplify, we get:

Total = 4X plus 2

Hence, 4X + 2 is the total number of shoes for both individuals.

An angle measures 62° more than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

one angle measures 76°, and
its complementary angle measures 90° - 76° = 14°.

Step by step explanation:

Two angles are complementary if the sum of their measures is 90°. Let x be the measure of one angle, then the measure of its complementary angle is 90° - x.

The problem states that one angle measures 62° more than the measure of its complementary angle, so we can set up the following equation:

x = (90° - x) + 62°

Simplifying and solving for x:

x = 90° - x + 62°
2x = 152°
x = 76°

Therefore, one angle measures 76°, and
its complementary angle measures 90° - 76° = 14°.

Company A will charge less than Company B for any mileage greater than 70 miles. For mileages less than 70 miles, Company B will be cheaper. The inequality solved is m > 70.

To determine for what mileages Company A will charge less than Company B, we can set up an inequality with m representing the number of miles driven.

Let's start by finding the total cost for each company based on the number of miles driven:

Company A: $138 (unlimited mileage)

Company B: $75 + $0.90m (where m is the number of miles driven)

To find the mileage for which Company A will charge less than Company B, we need to set up an inequality by equating the total cost for Company A to the total cost for Company B and then solving for m:

138 < 75 + 0.90m

The value of x and y for the given set of values in triangle are 8√3 units and 12 units.

What is triangle?

A triangle is a polygon with three sides and three angles. It is the simplest polygon that can exist in Euclidean geometry. The sum of the three interior angles of a triangle is always 180 degrees. Triangles can be classified according to the length of their sides and the measure of their angles. The most common classifications are:

Scalene triangle: A triangle with all three sides of different lengths.

Isosceles triangle: A triangle with two sides of equal length.

Equilateral triangle: A triangle with all three sides of equal length.

Acute triangle: A triangle in which all angles are less than 90 degrees.

Obtuse triangle: A triangle in which one angle is greater than 90 degrees.

Right triangle: A triangle in which one angle is exactly 90 degrees.

Here,

Using the given information:

side1 = 8√3

angle1 = 60°

We can use trigonometric ratios to find the values of x and y:

sin(60°) = y / side1

Simplifying:

y = side1 * sin(60°)

y = 8√3 * sin(60°)

y = 8√3 * (√3 / 2)

y = 12

The answer to subtracting the two polynomials is 2x2 - 10x - 7.  The process of subtracting polynomials is like that of subtracting any other type of numerical expression.

What are polynomials?

Polynomials are mathematical expressions consisting of variables, coefficients, and exponents. They are used to represent a variety of functions, such as polynomial equations, rational equations, and trigonometric functions.

In this case, our like terms are 2x2 and 4x2, and -6x and -4x, and -4 and +3. We begin by subtracting the coefficients of the like terms. We subtract the coefficient of the term with the highest power first. In this case, that is 2x2 and 4x2, we subtract 2 from 4 to get 2. Next, we subtract the coefficients of the terms with the second highest power. This is -6x and -4x, so we subtract -6 from -4 to get -2. Thus, our answer now reads 2x2 -2x.

Finally, we subtract the coefficients of the terms with the lowest power. This is -4 and +3, so we subtract -4 from 3 to get -7. Thus, our answer now reads 2x2 -2x -7.

The population is divided into smaller, more manageable clusters that are less difficult to study than the entire population.Therefore, cluster sampling is an excellent alternative when the target population cannot be measured because it is too large, too vast, or too hard to reach. In this technique, clusters are chosen by a random process or some other procedure.The final sampling method is achieved by selecting samples from within the clusters, which are frequently chosen using simple random sampling or some other appropriate method. When it comes to cluster sampling, it's important to remember that the clusters chosen must be heterogeneous internally but homogeneous externally.

carlos and juan take 5 hours to do a job. carlos alone takes 8 hours to do the same job. how long would it take juan to do the same job alone?

Answers

13.33 hrs long would it take juan to do the same job alone.

Here, we have,

given that,

carlos and juan take 5 hours to do a job.

carlos alone takes 8 hours to do the same job.

let, x hr long would it take juan to do the same job alone.

now, we have,

1 hr work of carlos = 1/8

1 hr work of juan = 1/x

1 hr work of both = 1/8 + 1/x = (x+8)/8x

we have,

So they together can do this job in = 5 hours

so, ATQ, we get,

(x+8)/8x = 1/5

or, (5x+40) = 8x

or, 3x = 40

or. x = 13.33

Hence, 13.33 hrs long would it take juan to do the same job alone.

What is the volume of a triangular prism that has 75 cm and has a base with an area of 30 cm

Answers

The volume of the triangular prism is 24 cm³.

Define triangular prism

A triangular prism is a three-dimensional geometric shape that has two parallel, congruent triangular bases and three rectangular faces connecting the bases. The rectangular faces are perpendicular to the bases and to each other. The height of the prism is the perpendicular distance between the two parallel bases

the Pythagorean theorem to find the length of the third side:

a² + b² = c²

where a and b are the lengths of the two equal sides, and c is the length of the third side (the base of the triangle).

Since we know that the base has a length of 75 cm and the area is 30 cm², we can solve for one of the equal sides using the formula for the area of a triangle:

Area = (base × height) / 2

30 cm² = (75 cm×height) / 2

height = 0.8 cm

Now we can use the formula for the volume of a triangular prism:

Volume = Base Area× Height

Volume = 30 cm² ×0.8 cm

Volume = 24 cubic centimeters (cm³)

Therefore, the volume of the triangular prism is 24 cm³.
