Una carretera recta tiene un ángulo de elevación de 3 grados respecto al plano horizontal. ¿Qué distancia hay que recorrer para alcanzar una elevación de 30 metros sobre la horizontal?
Answers
Answer:
572.4 m
Step-by-step explanation:
Fórmula del ángulo de elevación =
tan θ = Opuesto / Adyacente
θ = 3 °
Opuesto = 30 m
Adyacente =?
Por eso
bronceado 3 = 30 m / x
Multiplicar cruzada
bronceado 3 × x = 30 m

Don Carlos quiere colocar una cisternas cilíndrica con una capacidad de 2500lts y un diámetro de 1. 50 metros ¿cuánto debe excavar para que la cisterna quede al nivel del piso?
Answers
We need to excavate 15.92 meters in order to make the cistern level with the floor.
To calculate the amount of excavation needed for the cistern to be level with the floor, we must use the formula for the volume of a cylinder. The formula for the volume of a cylinder is V = πr2h, where V is the volume, r is the radius, and h is the height.
Since the diameter of the cistern is 1.50 meters, the radius is 0.75 meters. The volume of the cistern is 2500 liters, so the height is calculated by rearranging the formula to h = V/πr2. This gives us h = 2500/π(0.752), or h = 15.92 meters.
Therefore, we need to excavate 15.92 meters in order to make the cistern level with the floor.

The probability of a student passing the multiple-choice quiz by guessing all the questions correctly is 1/4.
In a multiple-choice quiz with 6 equally weighted questions, each question has four possible choices (A, B, C, or D). Since the student is guessing all the questions, there is a 1/4 chance (or 25% probability) of getting each question right by random chance alone.
To calculate the probability of guessing all the questions correctly, we multiply the probabilities of guessing each question correctly together. Since all the questions are independent events, the probabilities multiply. Thus, the probability of guessing all six questions correctly is (1/4) * (1/4) * (1/4) * (1/4) * (1/4) * (1/4), which simplifies to (1/4)^6.
Simplifying further, (1/4)^6 is equal to 1/4096. Therefore, the probability of guessing all the questions correctly and passing the quiz by random chance is 1 in 4096, or approximately 0.0244%.
In conclusion, if the student guesses all the questions on the multiple-choice quiz, the probability of passing the quiz is 1/4, or 25%. However, the chance of guessing all the questions correctly is incredibly low at 1 in 4096, indicating that the student would likely need to rely on knowledge and understanding of the quiz material to pass successfully.

suppose you walk at the of 210 ft/min. you need to walm 10,000 ft. how many more minutes will it take you to finish if you have already walked 550 ft.
Answers
It will take you 45 more minutes to finish walking the remaining distance.
If you have already walked 550 ft, subtracting it to the total distance you need to walk, then the remaining distance will be:
10,000 ft - 550 ft = 9450 ft
Rate is the relationship between two quantities of different units. Rate of speed is the amount of distance over total time.
If you walk at the rate of 210 ft/min, then the time it will take you to finish the remaining distance will be:
rate = distance/time
time = distance/rate
time = 9450 ft/(210 ft/min)
time = 45 mins
Hence, it will take you 45 more minutes to finish the walk.

The median number of siblings for all the 300 students selected randomly from two schools and surveyed is equals to the 1. So, the correct choice for this problem is option (b).
The median of a data set is the middle value when the data points are sorted in either ascending or descending order. In case of odd number of data values, the middle value is median but in case of even number of values the arithmetic mean two middle value is median. We have a total of 600 data points provided, which is even so the median will be the average of the 300ᵗʰ and 301ᵗʰ data points. When the data points are sorted in order
siblings value 1 through 260 is 0.Siblings value 261 through 450 is equals to 1.siblings value 451 through 540 is 2.Siblings value 541 through 580 is 3.Siblings values 581 through 600 is equals to 4.Therefore, both the 300ᵗʰ and 301ˢᵗ values are 1, and hence the median is 1.

thomas invests $105 in an account that pays 5 percent simple interest. how much money will thomas have at the end of 5 years?
Answers
Thomas will have $131.25 in his account at the end of 5 years, considering a simple interest rate of 5 percent on his initial investment of $105.
Simple interest is calculated based on the initial amount of money invested, known as the principal, and the interest rate. The formula for calculating simple interest is:
Interest = Principal × Rate × Time
Where:
Principal is the initial amount of money invested.
Rate is the interest rate, expressed as a decimal.
Time is the duration of the investment in years.
In this case, Thomas has invested $105, and the interest rate is 5 percent, which can be written as 0.05 in decimal form. The time period is 5 years. Let's substitute these values into the formula to calculate the interest earned:
Interest = $105 × 0.05 × 5
= $26.25
The interest earned over 5 years is $26.25. To determine the total amount of money Thomas will have at the end of 5 years, we need to add the interest to the initial investment:
Total amount = Principal + Interest
= $105 + $26.25
= $131.25
Therefore, at the end of 5 years, Thomas will have a total of $131.25 in his account.

Train A runs back and forth on an east-west section of railroad track.

Selected values for vA(t) are given in the table below.t (Minutes) 0 2 5 8 12vA(t)(meters/minute) 0 100 40 -120 -150Find the average acceleration of train A over the interval 2 ≤ t ≤ 8.
Answers
The average acceleration of Train A over the interval 2 ≤ t ≤ 8 is -40 meters per minute squared.
Explanation:
The average acceleration of a body over a given time interval is defined as the change in velocity divided by the time interval. In this case, we are given the velocity function vA(t) for Train A, and we want to find its average acceleration over the interval 2 ≤ t ≤ 8.
To find the change in velocity over this interval, we can subtract the velocity at t=2 from the velocity at t=8:
Δv = vA(8) - vA(2) = (-120) - 100 = -220 meters per minute
To find the time interval, we can subtract 2 from 8:
Δt = 8 - 2 = 6 minutes
Now we can use the formula for average acceleration:
a = Δv/Δt = (-220)/6 = -40 meters per minute squared
Therefore, the average acceleration of Train A over the interval 2 ≤ t ≤ 8 is -40 meters per minute squared.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails. The contractor bought 3 more small boxes than large boxes, which altogether had 2950 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.
Answers
The number of small boxes and large boxes for the given linear equation condition purchased is 10 and 7 respectively.
What is a linear equation?
Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
According to the question, a builder needs to purchase nails in order to construct a house.
Both small and large boxes of nails are provided. There are 50 nails in each small box and 350 in each large box.
The contractor purchased 3 more small boxes than large boxes, hence it is assumed that he purchased an 'x' number of large boxes.
He purchased (x+3) small boxes.
So, 50(x+3) + 350(x) = 2950.
50x + 150 + 350x = 2950.
400x = 2950 - 150.
400x = 2800.
x = 7.
∴ The no. of large boxes he purchased is 7.
∴ The no. of small boxes he purchased is 10.

To do this first multiply both sides by cos(θ), this gives you (cos^2θ)/1+sinθ = 1-sinθ
Then, multiply both sides by sinθ. This equals cos^θ=1-sin^2θ.
Finally, add sin^2θ to both sides. This equals the final answer of cos^2θ+sin^2θ=1. Which is true.

what is the vertex of h=-16t^2+29t+6 and its domain and range, and x and y axis?
Answers
Domain = {t | t ∈ ℝ } or (-∞, ∞)
h = 6
Step by step explanation:
The given quadratic function is h = -16t^2 + 29t + 6.
To find the vertex, we can use the formula:
t = -b / 2a
where a = -16 and b = 29 are the coefficients of the t^2 and t terms, respectively.
Substituting the values of a and b, we get:
t = -29 / 2(-16) = 29 / 32
Substituting this value of t into the original equation, we can find the corresponding value of h:
h = -16(29/32)^2 + 29(29/32) + 6 ≈ 13.47
Therefore, the vertex of the parabola is (29/32, 13.47).
The domain of the function is all real numbers because there are no restrictions on the possible input values of t.
To find the range, we can consider that the coefficient of the t^2 term is negative, which means that the parabola opens downward. Therefore, the vertex is the maximum point of the parabola, and the range is all real numbers less than or equal to the y-coordinate of the vertex, which is approximately 13.47.
The x-axis is the set of values where h = 0. We can use the quadratic formula to find the roots of the equation:
-16t^2 + 29t + 6 = 0
The roots are approximately t = -0.15 and t = 1.92. Therefore, the parabola intersects the x-axis at t = -0.15 and t = 1.92.
The y-axis is the set of values where t = 0. Substituting t = 0 into the equation for h, we get:
h = -16(0)^2 + 29(0) + 6 = 6
Therefore, the parabola intersects the y-axis at h = 6.

(6)
Answers
Calvin's statement suggests that the median number of minutes late in the winter is higher than 12.7 minutes, and the train service in the winter is less consistent compared to the summer.
To verify if Calvin is correct, we need to analyze the given data.
The given data for the number of minutes late in the winter are 8, 32, 44, 5, 17, 67, 9, 14, 10, and 26. To determine the median, we arrange the data in ascending order: 5, 8, 9, 10, 14, 17, 26, 32, 44, 67. The middle value in this ordered list is 14, which means that the median number of minutes late in the winter is 14 minutes.
Comparing the median values for the summer (12.7 minutes) and the winter (14 minutes), we can see that Calvin is correct in stating that the median number of minutes late increases in the winter.
To evaluate the consistency of the train service, we can consider the range. The range is the difference between the highest and lowest values in the data set. In the winter data, the highest value is 67 and the lowest value is 5, giving a range of 62 minutes. Comparing this range with the given range in the summer of 11 minutes, we can conclude that Calvin is also correct in asserting that the train service is less consistent in the winter.
In summary, based on the analysis of the given data, Calvin's statement is correct. The median number of minutes late in the winter is higher than in the summer, indicating an increase in lateness, and the range of the number of minutes late in the winter is larger, suggesting a less consistent train service.
