ra elaborar un pastel de 2 kg, se necesitan, ¾ de kg de harina y 4 huevos (con un peso de 100 gr cada uno), además de otros ingredientes. ¿Cuál es el peso que tienen los demás ingredientes del pastel?

Answer:

p = 6\(\sqrt{2}\)

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = \(\frac{1}{\sqrt{2} }\) , then

cos45° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{6}{p}\) = \(\frac{1}{\sqrt{2} }\) ( cross- multiply )

p = 6\(\sqrt{2}\)

Step-by-step explanation:

The correct option is - C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Reason -

Option A is incorrect because the statistics can not be incorrect.

Option B is incorrect because they are not talking about the city.

Option C is correct because Urban rail reduces congestion.

Option D is incorrect because the opposers cited the example of one city and the supporters are presenting evidence in the case of that city itself.

We are given the demand function D(p) = 100 - 2p and we need to find the Elasticity of Demand (E) at a price of $4.

Step 1: Calculate the quantity demanded at the given price At p = $4, the demand function is: D(4) = 100 - 2(4) = 100 - 8 = 92

Step 2: Calculate the first derivative of the demand function with respect to price (dD/dp) dD/dp = -2 (since the derivative of 100 - 2p with respect to p is -2)

Step 3: Calculate the Elasticity of Demand (E) using the formula E = (dD/dp)*(p/D(p)) E = (-2)*(4/92) = -8/92 ≈ -0.087

Since the Elasticity of Demand (E) is between 0 and -1, the demand is inelastic at this price. Based on this, to increase revenue, we should raise prices because when demand is inelastic, raising prices will lead to a smaller decrease in quantity demanded and an overall increase in revenue.

Given that $OF = 9$ and $OF' = 12,$ where $F$ and $F'$ are the foci of the ellipse, we can determine the lengths of the major and minor axes.

In an ellipse, the sum of the distances from any point on the ellipse to the two foci is constant. This property is expressed by the equation:

$$PF + PF' = 2a,$$

where $P$ is any point on the ellipse and $a$ is the semi-major axis. In our case, $P = O,$ and since $OF = 9$ and $OF' = 12,$ we have:

$$9 + 12 = 2a,$$

$$21 = 2a.$$

Therefore, the semi-major axis $a$ is equal to $\frac{21}{2} = 10.5.$

The distance between the center of the ellipse and each focus is given by $c,$ where $c$ is related to $a$ and the semi-minor axis $b$ by the equation:

$$c = \sqrt{a^2 - b^2}.$$

We can solve for $b$ using the distance to one focus:

$$c = \sqrt{a^2 - b^2},$$

$$c^2 = a^2 - b^2,$$

$$b^2 = a^2 - c^2,$$

$$b = \sqrt{a^2 - c^2}.$$

Substituting the known values:

$$b = \sqrt{10.5^2 - 9^2},$$

$$b = \sqrt{110.25 - 81},$$

$$b = \sqrt{29.25},$$

$$b \approx 5.408.$$

Therefore, the semi-minor axis $b$ is approximately $5.408.$

Finally, we can determine the lengths of the major and minor axes:

The major axis $\overline{AB}$ is twice the semi-major axis, so $\overline{AB} = 2a = 2(10.5) = 21.$

The minor axis $\overline{CD}$ is twice the semi-minor axis, so $\overline{CD} = 2b = 2(5.408) \approx 10.816.$

Therefore, the major axis $\overline{AB}$ is $21$ units long, and the minor axis $\overline{CD}$ is approximately $10.816$ units long.

Answer:

The slope of the line passing through the points (1, -1) and (4, 8) is 3.

Step-by-step explanation:

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the following formula:

\(slope = (y2 - y1) / (x2 - x1)\)

Here, the given points are (1, -1) and (4, 8). So,

\(slope = (8 - (-1)) / (4 - 1) = 9 / 3 = 3\)

Therefore, the slope of the line passing through the points (1, -1) and (4, 8) is 3.

Answer:

A: y = -2/5x - 1

B: 2x + 5y = -5

E: y - 1 = -2/5(x+5)

Step-by-step explanation:

I only got 2 out of 3 answers, but the ones listed above should be correct :) Hope this helps! :D

The equation of the line is 2x + 5y = -5.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line that is parallel to the line 2x + 5y = 10 will have the same slope as the given line, which is -2/5.

Using the point-slope form of the equation of a line, we can find the equation of the line passing through the point (-5, 1) with slope -2/5:

y - 1 = (-2/5)(x + 5)

Multiplying both sides by 5.

5y - 5 = -2x - 10

Adding 10 to both sides.

2x + 5y = -5

Now,

2x + 5y = -5

This can be written as,

5y = -2x -5

y = (-2/5)x - 1

Thus,

The equation of the line is 2x + 5y = -5.

Answer:

72,630

Step-by-step explanation:

630 + 7.2 x 10^4= 72,630

The value of the  product of 630 & 7.2×10⁴ is 4.536 x 10⁷.

The standard form for a number is a method by which we write number in a format like b×10ˣ. The value of b should be in between 0 to 10.

To multiply two numbers in scientific notation, we can first multiply their coefficients and then add their exponents.

630 can be written as 6.3 x 10² in scientific notation.

7.2 x 10⁴ is already in scientific notation.

So, the product of 630 and 7.2 x 10⁴ can be found by multiplying the coefficients and adding the exponents:

(6.3 x 10²) x (7.2 x 10⁴)

= (6.3 x 7.2) x (10² x 10⁴) (using the distributive property of multiplication)

= 45.36 x 10⁶ (multiplying the coefficients)

= 4.536 x 10⁷ (simplifying the exponent by moving the decimal point to the left)

Therefore, the product of 630 and 7.2 x 10⁴ is 4.536 x 10⁷.

The appropriate p-value for a t-value of 2.73 with 5 degrees of freedom is approximately 0.05. This indicates that there is a 5% chance of observing a t-value as extreme as 2.73 or more extreme, assuming the null hypothesis is true.

In statistics, the p-value measures the strength of evidence against the null hypothesis. The null hypothesis states that there is no significant difference or effect in the population being studied. The p-value is calculated by determining the probability of obtaining a test statistic (in this case, the t-value) as extreme as or more extreme than the observed value, assuming the null hypothesis is true.

To determine the appropriate p-value for a t-value, we typically consult a t-distribution table or use statistical software. In this case, with 5 degrees of freedom and a t-value of 2.73, we look up the critical value or use software to find the corresponding p-value. The p-value associated with a t-value of 2.73 and 5 degrees of freedom is approximately 0.05.

The p-value of 0.05 indicates that there is a 5% chance of obtaining a t-value as extreme as 2.73 or more extreme, assuming the null hypothesis is true. Generally, a p-value of 0.05 or lower is considered statistically significant, implying that the observed result is unlikely to have occurred by chance alone. If the p-value is below a predetermined significance level (often denoted as α, commonly set at 0.05), we reject the null hypothesis in favor of an alternative hypothesis. If the p-value is above the significance level, we fail to reject the null hypothesis.

He should invest $86.29 in the account now, which has a 7% interest compounded monthly.

Compound interest refers to the amount of interest added on the principal amount plus interest. The formula for compound interest is:

B = P(1 + r/n)^t

where B is the ending balance, P is the principal amount or original balance, r is the interest rate in decimal form, n = number of times interest is compounded monthly, and t is the time in number of months

Based on the given information, P is the unknown and

B = $5000

t = 5 years = 60 months

r = 7% = 0.07

n = 1

Plug in the values and solve for P or the amount that should be invested today.

B = P(1 + r/n)^t

$5000 = P(1 + 0.07/1)^60

$5000 = P(1.07)^60

P = $5000/(1.07)^60

The surface area of the house is 74.322 m², the volume of the house in cubic inches is 18,720,000 cu in, and the volume of the house in m³ is 0.338 m³.

Given: Length of the house = 50 ft

Width of the house = 26 ft

Height of the house = 100 inches

a) To find the surface area of the house in m²

In order to calculate the surface area of the house, we need to convert feet to meters. To convert feet to meters, we will use the formula:

1 meter = 3.28084 feet

Surface area of the house = 2(lw + lh + wh)

Surface area of the house in meters = 2(lw + lh + wh) / 10.7639

Surface area of the house in meters = (2 x (50 x 26 + 50 x (100 / 12) + 26 x (100 / 12))) / 10.7639

Surface area of the house in meters = 74.322 m²

b) To calculate the volume of the house in cubic inches, we will convert feet to inches.

Volume of the house = lwh

Volume of the house in inches = lwh x 12³

Volume of the house in inches = 50 x 26 x 100 x 12³

Volume of the house in inches = 18,720,000

c) We can either use the value of volume of the house in cubic inches or we can use the value of surface area of the house in meters.

Volume of the house = lwh

Volume of the house in meters = lwh / (100 x 100 x 100)

Volume of the house in meters = (50 x 26 x 100) / (100 x 100 x 100)

Volume of the house in meters = 0.338 m³ or

Surface area of the house = lw + lh + wh

Surface area of the house = (50 x 26) + (50 x (100 / 12)) + (26 x (100 / 12))

Surface area of the house = 1816 sq ft

Area of the house in meters = 1816 / 10.7639

Area of the house in meters = 168.72 m²

Volume of the house in meters = Area of the house in meters x Height of the house in meters

Volume of the house in meters = 168.72 x (100 / 3.28084)

Volume of the house in meters = 515.86 m³

A boxplot is a graphical representation of data distribution, and it can be used to compare the salary distributions of construction workers and teachers. To determine the percentage of teachers that a person making the minimum salary for a construction worker is making more than, we must first understand the data for both groups.

The minimum salary for a construction worker is a specific value, representing the lowest amount paid to workers in that profession. In contrast, teachers' salaries can vary based on various factors such as experience, education level, and location. Comparing these two distributions can provide insights into the relative earnings of these professions.

Using a boxplot, the minimum, first quartile, median, third quartile, and maximum values can be visually represented for each group. The comparison between the minimum salary for a construction worker and the distribution of teachers' salaries can be observed by looking at the overlap of these two boxplots.

If the minimum salary for a construction worker falls within the first quartile of teachers' salaries, it would mean that a person earning that salary is making more than 25% of teachers. If it falls within the second quartile (between the first and median), the person is making more than 50% of teachers. Similarly, if it falls within the third quartile, they would be making more than 75% of teachers.

To provide a precise percentage, the data for both groups needs to be analyzed and compared. However, without specific numbers, a definitive answer cannot be given. In summary, a boxplot can be used to visualize and compare the salary distributions of construction workers and teachers to determine what percentage of teachers a person making the minimum salary for a construction worker is earning more than.
