Answer:

x = 26.

Step-by-step explanation:

Given: 2x + 3x + 50 = 180

First, write it down:

2x + 3x + 50 = 180

Then, collect like terms:

2x + 3x = 180 - 50

Then calculate:

5x = 130  (Divide both sides by 5)

x = 26

To simplify the quotient √50/√10, we need to factor out the largest perfect square that divides each radicand. In this case, we can factor out 25 from both 50 and 10 to get:

√50/√10 = √(252) / √(252) = √25 * √2 / √25 * √2 = √2

Therefore, the simplified form of the quotient is √2. Among the given choices, options B and E are equivalent to √2, as √15/√3 can be simplified as √(35)/√3 = √5 * √3 / √3 * √3 = √5/√3, and √3 is the same as √(31) and there is no √2 term in the denominator to combine with it. Hence, the options B and E are equivalent to the quotient √50/√10.

Yes, it is possible to calculate the length of the altitude to the other side of the triangle. To do so, use the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this triangle, the hypotenuse is the side of length 13 and the other two sides are the side of length 5 and the altitude to it. So, the equation to use is:

132 = 52 + altitude2

Solving for altitude gives:

altitude2 = 132 - 52

altitude2 = 169 - 25

altitude2 = 144

altitude = √144 = 12

Therefore, the length of the altitude to the side of the triangle with length 13 is 12.

Answer: C. 12 inches

Step-by-step explanation: Let's use the formula for the volume of a cylinder, which is:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

We ar given that the length of the radius is twice the height, which can be written as:

r = 2h

We are also given the volume of the cylinder, which is 864 cubic inches. Substituting the given values, we get:

864 = π(2h)^2h

Simplifying and solving for h:

864 =4πh^3

h^3 = 864/(4π)

h = 6

Now that we know the height of the cylinder is 6 inches, we can find the radius using the equation r = 2h:

r = 2(6) = 12 inches

Therefore, the length of the radius of the cylinder is 12 inches, which is option C.

Step-by-step explanation:

If there are ten families and exactly two of them are childless, then there are 10 - 2 = 8 families with children.

The total number of children in these families is 8 x 2 = 16.

Therefore, the average number of children in the families with children is:

16 / 8 = 2

So the average number of children in the families with children is 2.0 (to the nearest tenth).

The average number of children in the families with children is 2.2.

To calculate this, first we need to determine the total number of children in the ten families. Since each family has an average of 2 children, this means that the total number of children in the ten families is 10 x 2 = 20.

Since two of these families are childless, this means that the total number of children in the remaining 8 families is 20 – 0 = 20.

Now, we need to determine the average number of children in the 8 families with children. To do this, we divide the total number of children (20) by the number of families with children (8):

20/8 = 2.5

Finally, we express the answer to the nearest tenth, which is 2.2.

In conclusion, the average number of children in the families with children is 2.2.

Answer:

20- gon

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

given the sum of the interior angles is  3240° , then

180° (n - 2) = 3240 ( divide both sides by 180° )

n - 2 = 18 ( add 2 to both sides )

n = 20

The maximum value of f on the given region is 9 and the minimum value of f is 25.

In plainer terms, a function creates an output in response to an input. As an illustration, the formula f(x) = x2 takes the input value x, squares it, and outputs the square of x. The set of all potential output values is referred to as the range, while the set of input values that can be employed with a specific function is referred to as the domain.

In order to simulate real-world processes and make predictions, functions are frequently employed in mathematics, physics, engineering, and many other disciplines. They can be represented by mathematical equations, tables, or graphs, and can take on a variety of shapes, such as linear, quadratic, exponential, trigonometric, and many more.

We need to find the extreme values of the function f(x,y) subject to the constraint x² + y² <= 16. We can use the method of Lagrange multipliers to solve this problem.

Let g(x,y) = x² + y² - 16, then the Lagrangian function is given by:

L(x,y,λ) = f(x,y) - λg(x,y)

= 2x² + 3y² - 4x - 7 - λ(x² + y² - 16)

Taking partial derivatives of L(x,y,λ) with respect to x, y and λ, and equating them to zero, we get:

∂L/∂x = 4x - 4λx = 0

∂L/∂y = 6y - 4λy = 0

∂L/∂λ = x² + y² - 16 = 0

Solving these equations, we get two critical points:

(2/λ, 0, λ) and (-2/λ, 0, λ)

To find the extreme values of f, we need to evaluate f at these critical points and at the boundary of the region x² + y² = 16.

At the critical points, we have:

f(2/λ, 0) = -7 - 16λ/3

f(-2/λ, 0) = -7 - 16λ/3

At the boundary, we have:

f(x,y) = 2x² + 3y² - 4x - 7

= 2x² + 3(16 - x²) - 4x - 7 (substituting y² = 16 - x²)

= -x² - 4x + 41

To find the extreme values, we need to compare the values of f at these points:

f(2/λ, 0) = f(-2/λ, 0) = -7 - 16λ/3

f(x,y) = -x² - 4x + 41

Now, we need to find the maximum and minimum values of f on the given region. Since the coefficient of x² is negative, the maximum value of f occurs at the boundary of the region, where x = ±4. Therefore, the maximum value of f is:

f(4,0) = -4² - 4(4) + 41 = 9

To find the minimum value of f, we need to compare the values of f at the critical points and the boundary. Since the coefficient of x² is negative, we can see that f(2/λ, 0) and f(-2/λ, 0) approach -∞ as λ → 0. Therefore, the minimum value of f occurs at the boundary of the region, where x = ±4. Therefore, the minimum value of f is:

f(-4,0) = -(-4)² - 4(-4) + 41 = 25

Hence, the maximum value of f on the given region is 9 and the minimum value of f is 25.

In the bridge, when the south has 13 points and 3 clubs and bids 1 club, the north responding with 3 clubs means that the North has a strong hand with six or more clubs.

In the game of bridge, bidding is a method of indicating the strength of a player's hand, which is the number of tricks that they believe they can win if they become the declarer. Every player has to declare their abilities based on the bid of the previous player when it is their turn to bid.

The bidding starts with the dealer and proceeds in a clockwise direction. The players can either make a bid or pass. The following are the four basic bids in Bridge:

When South has 13 points and 3 clubs, he makes a 1 Club bid. This bid can be interpreted as follows:

South has a strong hand with five or more clubs and 13 to 21 high card points. When South bids 1 Club, he implies that he has a balanced hand, which means that he has four cards in each suit, or an unbalanced hand, which means that he has a long suit, a singleton, or a void in some other suit.

When North responds with 3 Clubs, it means that he has a strong hand with six or more clubs. North has understood that South has five or more clubs and therefore responds with the number of clubs that he has in his hand to show that he is strong enough to support South's suit. Thus, North is trying to force South to become the declarer in clubs.

A right circular cylinder can be generated by rotating a rectangle of perimeter p about one of its sides. The dimensions of the rectangle that will generate the cylinder of max volume are l = p/6 and w = p/2 - l = 2p/3.

Explanation: Let l and w be the dimensions of the rectangle of perimeter p.

That is, the rectangle's perimeter is given by p = 2l + 2w or p/2 = l + w. Therefore, the width w = p/2 - l. The area of the rectangle is given by lw. When the rectangle is rotated around the side of length w, it generates a cylinder of height l and radius w.

The volume of the cylinder is given by V = πr²h = πw²l. Substituting w = p/2 - l, we obtain V = π(p/2 - l)²l = π(p/2)²l - 2π(p/2)l² + πl³.

The volume function can be obtained by differentiating V with respect to l, setting the derivative equal to 0, and solving for l. The derivative of V with respect to l is given by dV/dl = π(p/2)² - 4π(p/2)l + 3πl².

Setting dV/dl = 0 and solving for l, we obtain l = p/6.The dimensions of the rectangle that will generate the cylinder of max volume are l = p/6 and w = p/2 - l = 2p/3.

By using Central Limit Theorem, the distribution of to-go orders per hour over 700 random hours at a restaurant with a rate of 10 per hour can be approximated by a normal distribution with a mean of 10 and a standard deviation of 0.119.

The distribution of the average number of to-go orders per hour over 700 random hours can be approximated by the Central Limit Theorem (CLT). In this case, the population mean (μ) is 10 to-go orders per hour, and the population standard deviation (σ) can be calculated using the Poisson distribution formula:

σ = sqrt(μ) = sqrt(10) ≈ 3.162

The sample size (n) is 700, which is larger than 30, so we can use the CLT to approximate the distribution of the sample means. The mean of the sample means is equal to the population mean, which is 10 to-go orders per hour. The standard deviation of the sample means (also called the standard error) is equal to:

SE = σ / sqrt(n) = 3.162 / sqrt(700) ≈ 0.119

Therefore, the distribution of the average number of to-go orders per hour over 700 random hours is approximately normal with a mean of 10 and a standard deviation of 0.119

The probability of duplicating the exact sequence of 26 straight blacks that occurred on August 18, 1913, is extremely low. Each spin of the wheel is an independent event, so the probability of getting a black on any given spin is always 18/37, regardless of what happened on previous spins.

To calculate the probability of getting 26 straight blacks, we can use the formula for the probability of a sequence of independent events, which is the product of the probabilities of each event. Therefore, the probability of getting 26 straight blacks is (18/37)^26, which is an extremely small number, approximately 3.143 x 10^-16.

Therefore, the probability of duplicating the 26 straight blacks that occurred on August 18, 1913, is so low that it's effectively impossible.

As per the concept of confidence interval, we can be 90% confident that the true proportion of red candies in all the bags is between 0.195 and 0.285.

To do this, we first need to determine the level of confidence we want for our interval.

Next, we use a formula to calculate the confidence interval. The formula for a confidence interval for a population proportion is:

p ± z x √(p(1-p)/n)

where p is the sample proportion (in this case, 120/500 = 0.24), z* is the z-score that corresponds to the desired level of confidence (for a 90% confidence interval, z* = 1.645), and n is the sample size (in this case, 500).

Substituting the values into the formula, we get:

0.24 ± 1.645 x √(0.24(1-0.24)/500)

Simplifying, we get:

0.24 ± 0.045

13.0% of kci by a mass of a solution of 2 moles of kci dissolved in 1 litres of pure water

To find the percent of KCI in a solution of 2 moles of KCI dissolved in 1 liter of pure water (H2O), we first need to calculate the molar mass of KCI.

Molar mass of KCI = atomic mass of K + atomic mass of Cl = 39 + 35.5 = 74.5 g/mol

Next, we need to calculate the mass of KCI in the solution using the formula:

mass = moles x molar mass

mass of KCI

= 2 moles x 74.5 g/mol

= 149 g

Finally, we can calculate the percent of KCI in the solution using the formula:

percent of KCI = (mass of KCI / total mass of solution) x 100%

The total mass of the solution is equal to the mass of KCI plus the mass of water, which is:

total mass of solution

= 149 g + 1000 g

= 1149 g

So, the percent of KCI in the solution is:

percent of KCI

= (149 g / 1149 g) x 100%
