The amount of water that must be pumped into the tank to eliminate 50% of the salt is 10,000 * s/(s*0.5).

The amount of water that must be pumped into the tank to eliminate 50% of the salt can be determined by rearranging the equation to solve for x:

x = (V*s)/(s*(1-0.5))

Given V = 10,000 gallons, s is the initial amount of salt, which can be found by multiplying V and the initial concentration of salt.

Therefore, the amount of water that must be pumped into the tank to eliminate 50% of the salt is x = (V*s)/(s*(1-0.5)) = 10,000 * s/(s*0.5).

The amount of water that must be pumped into the tank to eliminate 50% of the salt is 10,000 * s/(s*0.5).

Answer:

$25.44

Step-by-step explanation:

Although the starting price of the pair of jeans is $ 32, it is 25% off. Thus, 75% of its initial value (100-25) is being paid, with which the pre-tax price is determined as follows:

32 x 0.75 = X

24 = X

In turn, at that discounted price, 6% must be calculated as sales tax, with which the final price is determined through the following calculation:

24 x 1.06 = X

25.44 = X

Therefore, the price to pay for the pair of jeans is $ 25.44.

Answer: \(6\sqrt{6}\)

Step-by-step explanation:

\(\sqrt{12}=2\sqrt{3}\\\\\sqrt{18}=3\sqrt{2}\\\\\implies \sqrt{12} \sqrt{18}=2\sqrt{3}(3\sqrt{2}=\boxed{6\sqrt{6}}\)

The product of square root of 12 i.e.,√12 and square root of 18 i.e.,√18 is 6√6.

When two numbers has equal power then we can multiply the the numbers and the power remains same. The number in the power is called exponent and the number is called as base. In \(a^m\), \(m\) is the exponent and \(a\) is the base of the number \(a^m\).

Step-by-step explanation:

\(\sqrt{12}\)\(=\sqrt{4}\)×\(\sqrt{3}\)\(=2\)×\(\sqrt{3}\) , since the square root of 4 is 2

\(\sqrt{18}=\sqrt{2}\)×\(\sqrt{9}\)\(=\sqrt{2}\)×\(3\) , since the square root of 9 is 3

Now, \(\sqrt{12} \sqrt{18} = 2\)×\(3\)×\(\sqrt{2}\)×\(\sqrt{3}\) from above.

                       \(=6\sqrt{6}\)

Hence the product of √12 and √18  is √12√18=6√6

Answer:

10x + 15y ≥ 900

Step-by-step explanation:

She burns 10 calories per minute while biking and 15 calories per minute while running. For each exercise, the number of minutes multiplied by the number of calories burned per minute will give the total number of calories burned.

Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).

The inequality that models this situation is therefore

10x+15y≥900

The required inequality that models the given situation is 10x + 15y ≥ 900.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

While biking, she burns 10 calories per minute, and 15 calories per minute while running. The total number of calories burned for each exercise is the number of minutes multiplied by the number of calories burned per minute.

Let x be the number of minutes she spends biking and let y be the number of minutes she spends running.

Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).

As per the given situation, the required inequality would be as:

⇒ 10x + 15y ≥ 900

Thus, the required inequality that models the given situation is 10x + 15y ≥ 900.

Answer:

55°

Step-by-step explanation:

if angle 4 = 105°, then angle 3 must be 180 - 105 = 75° (angles in straight line add up to 180°).

angles in a triangle also add up to 180°.

so we expect angle 2 to be 180 - angle 6 - angle 3

= 180 - 50 - 75

= 55°.

Step-by-step explanation:

ANSWER:

Mia's iced coffee was above because the average temp. is 0.C and the instutuion of mia's iced coffee was 4.C. So, the average was 0 so 4 is higher than 0, so that gives that the value was ABOVE.

Part 1

The equation is \(y=a(x+8)(x-72)\).

Using the point \((62, -490)\) to solve for \(a\),

\(-490=a(62+8)(62-72) \implies a=\frac{7}{10}\\\\\therefore \boxed{y=\frac{7}{10}(x+8)(x-72)}\)

Part 2

When \(x=-8\), \(y=0\).

When \(x=2\), \(y=-490\).

So, the average rate of change is \(\frac{-490-0}{2-(-8)}=\boxed{-49}\)

24 - 6 = 18

18 ÷ 1/3  =  18 × 3 = 54

Step-by-step explanation:

The volume of the container is approximately 12.9516 cubic meters when rounded to the nearest hundredth.

To find the volume of the container, we need to multiply its length, width, and height. Let's convert the given measurements to meters to ensure consistent units.

The length of the container is 2.76 meters.

The width of the container is 23.5 decimeters, which is equal to 2.35 meters (since 1 decimeter = 0.1 meters).

The height of the container is 196 centimeters, which is equal to 1.96 meters (since 1 meter = 100 centimeters).

Now we can calculate the volume of the container:

Volume = Length × Width × Height

Volume = 2.76 meters × 2.35 meters × 1.96 meters

Volume ≈ 12.9516 cubic meters (rounded to four decimal places)

Therefore, the volume of the container is approximately 12.9516 cubic meters when rounded to the nearest hundredth.

Answer:r=2 cos^4(theta)

Step-by-step explanation:To find the values of theta where the maximum r-values occur on the graph of the polar equation r = 2 cos^4(theta), we need to find where the derivative of r with respect to theta is equal to zero, since the maximum r-values occur at these points.

First, we can simplify the equation by using the identity cos(2theta) = 2cos^2(theta) - 1 and substituting cos^2(theta) = (1 + cos(2theta))/2. This gives:

r = 2 cos^4(theta) = 2(1/2 + 1/2 cos(2theta))^2 = 1 + cos(2theta) + cos^2(2theta)/2.

Next, we can take the derivative of r with respect to theta, using the chain rule:

dr/dtheta = -sin(2theta) - 2cos(2theta)sin(2theta).

Setting this equal to zero and factoring out sin(2theta), we get:

sin(2theta)(-1 - 2cos(2theta)) = 0.

This equation is satisfied when sin(2theta) = 0 or cos(2theta) = -1/2.

When sin(2theta) = 0, we have 2theta = k*pi for some integer k. Therefore, theta = k*pi/2.

When cos(2theta) = -1/2, we have 2theta = 2*pi/3 + 2*k*pi or 2theta = 4*pi/3 + 2*k*pi for some integer k. Therefore, theta = pi/3 + k*pi or theta = 2*pi/3 + k*pi.

These are the values of theta where the maximum r-values occur on the graph of the polar equation r = 2 cos^4(theta).

The completely factored form of the polynomial 81x^4 - 16y^4 is:

(3x + 2y)(3x - 2y)(9x^2 + 4y^2)(9x^2 - 4y^2)

Apply the difference of squares formula:

(9x^2)^2 - (4y^2)^2

Factor the difference of squares:

(9x^2 + 4y^2)(9x^2 - 4y^2)

Apply the difference of squares formula again:

(3x)^2 + (2y)^2

(3x)^2 - (2y)^2

Factor the difference of squares:

(3x + 2y)(3x - 2y)

Putting it all together, the completely factored form of the polynomial 81x^4 - 16y^4 is:

Step-by-step explanation:

Solve the inequality by solving for x.

Solve:

-4(2x + 1) ≤ 3(x - 5)

Use the distributive property.

-8x - 4 ≤ 3(x - 5)

-8x - 4 ≤ 3x - 15

Subtract 3x from both sides.

-11x - 4 ≤ -15

Add 4 to both sides.

-11x ≤ -11

Divide both sides by -11, also flip the inequality since you're dividing by a negative number.

x ≥ 1

Your final answer would be x ≥ 1

Answer:

x ≥ 1

Step-by-step explanation:

Use the properties of inequalities and real numbers to solve the given inequality for x.

For the final step, divide both sides by -11. Since this is division by a negative number, the direction of the inequality should flip.

So, the solution to the inequality is x ≥ 1.

After answering the given query, we can state that As a result, choice B factor is the correct response: \(5(k^2- 4k + 6).\)

The greatest common divisor of two or more non-zero integers is defined in mathematics as the highest positive integer that divides the associated integers. The sum of two or more integers is the greatest common factor (HCF) of those numbers. It is commonly referred to as the largest common divisor as a result. (GCF). To find the largest common divisor, take the prime factors of the two (or more) integers and identify the shared prime factors. The largest common divisor after that is the sum of common prime factors. The greatest common factor of a given number is determined by dividing it by the largest integer.

First, we must determine the words 5k2, 20k, and 30's greatest common factor (GCF).

These terms have a GCF of 5, which is the biggest factor that divides into all three terms equally.

Then, for each term, we can figure out this GCF of 5:

\(-5k^2 + 20k - 30 = 5(-k^2 + 4k - 6)\)

As a result, choice B is the correct response: 5(k2  4k + 6).
