Se requiere saber la elevación x los 20.00 m de longitud , al construir una carretera , sabiendo que pendiente es de 5 %
Answer:
La elevación de la carretera es de aproximadamente 0.999 metros.
Step-by-step explanation:
Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:
[tex]\theta = \tan^{-1} 0.05[/tex]
[tex]\theta \approx 2.862^{\circ}[/tex]
La elevación de la carretera se determina mediante la función seno:
[tex]\sin \theta = \frac{h}{l}[/tex] (1)
Donde:
[tex]h[/tex] - Elevación de la carretera, medida en metros.
[tex]l[/tex] - Longitud de la carretera, medida en metros.
Si sabemos que [tex]l = 20\,m[/tex] y [tex]\theta \approx 2.862^{\circ}[/tex], entonces la elevación de la carretera es:
[tex]h = l\cdot \sin \theta[/tex]
[tex]h \approx 0.999\,m[/tex]
La elevación de la carretera es de aproximadamente 0.999 metros.
Considerando la regla de tres, la elevación de la carretera es de 1 metro.
Regla de tresLa regla de tres es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos.
Es decir, lo que se pretende con ella es encontrar el cuarto término de una proporción conociendo los otros tres.
Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, la otra también (o cuando una magnitud disminuye, la otra también), se debe aplicar la regla de tres directa.
Para resolver una regla de tres directa se debe seguir la siguiente fórmula, siendo a, b y c datos conocidos yx la variable a calcular:
a ⇒ b
c ⇒ x
Por lo tanto: [tex]x=\frac{cxb}{a}[/tex]
ElevaciónUna pendiente de 5% indica que por cada 100 m de longitud hay 5 m de pendiente.
Entonces podes aplicar la siguiente regla de tres: si por cada 100 m de longitud hay 5 m de pendiente o elevación, por 20 metros de longitud ¿cuál será la pendiente?
[tex]elevacion=\frac{20 metrosx5 metros}{100 metros}[/tex]
elevación= 1 metro
La elevación de la carretera es de 1 metro.

Monique bought 3 boxes of cereal at the grocery store. Each box of cereal costs c dollars. Which equation represents the total amount of money, t, Monique spent on cereal?
Answer:
3c = t
Step-by-step explanation:
3 cereal boxes is 3c and the total is t. so 3c = t
Answer:
3c = t
3 is the amount of boxes, c is the money, therefore, it is 3c=t, which means c times the number of boxes equals t

If 48% of the students in a certain college are female and there are 2,400 female students, how many students are male?
Answer:
2,600 male students
Step-by-step explanation:
[tex]\frac{2,400}{0.48} = 5,000[/tex]
There are 5,000 students in total.
Since 2,400 of them are female, the remaining students must be male.
5,000 - 2,400 = 2,600 male students
Write the area as a product:

Answer:
product is a ⋅ c = 3 ⋅ − 6 = − 18 and whose sum is b = − 7 .
Step-by-step explanation:
Factor
− 7 out of − 7 x .
3 x 2 − 7 ( x ) − 6
Rewrite
−7 as 2 plus −9
3 x 2 + (2−9) x −6
Apply the distributive property.
3 x 2 + 2 x − 9 x − 6
Solve for x, rounding to the nearest hundredth.
2^4x = 36
Answer:

Step-by-step explanation:
36 is the 5tf power of 2 so we can rewrite the equation as

Fill in the parenthesis for the equation of the circle:
(Blank 1)² +(Blank 2)²= (Blank 3)
*Just type what you would write in the parentheses with no spaces
Answer:
(x + 10)² + (y + 4)² = 232Step-by-step explanation:
Given Center = (-10, -4)Point on circle = (4, 2)To find The equation of circleSolutionRemember the standard equation of circle:
(x - h)² + (y - k)² = r², where (h, k) is the center and r is radiusWe have
h = -10, k = -4Use distance formula (Pythagorean theorem) to work out the length of the radius. We know that radius is the distance from the center to any point on the circle.
Here we are finding the distance between points (-10, -4) and (4, 2)
r² = (-10 - 4)² + (-4 - 2)² r² = 14² + 6²r² = 232So the equation is:
(x + 10)² + (y + 4)² = 2323. What is true about the graph of a system of equations that has infinitely many solutions? A. The lines will have the same slope but different y-intercepts. B. The lines will have the same slope and the same y-intercepts. C. The lines will have different slopes and different y-intercepts. D. The lines will have different slopes but the same y-intercepts.
Answer:
B
Step-by-step explanation: for infinitely many solutions the two lines must lie directly on top of one another- so same slope and same y-intercept
The lines in the graph of a system of equations that has infinitely many solutions will have The lines will have the same slope and the same y-intercepts.
What is a slope?A slope is a ratio that describes the steepness and the direction of a line.
What is the y-intercept?The y-intercept is the point at which a line touches the y-axis. This means that x=0.
A system of equations will have infinitely many solutions when they are the same line or when the two lines coincide on every point that makes up the line. Two lines are the same when the slope and the y-intercept of the lines are also the same.Thus we can say that the lines in the graph of a system of equations that has infinitely many solutions will have the same slope and the same y-intercepts.

Answer:
6
Step-by-step explanation:
The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be given as,
Perimeter of the rectangle = 2(L + W) units
The dimension of the rectangle is given as,
L = 9x - 4
W = 5x + 2
Then the perimeter of the rectangle is given as,
P = 2(L + W)
P = 2(9x - 4 + 5x + 2)
P = 2(14x - 2)
P = 18x - 4
The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.

2. The area of a square is represented by the expression 16m2 - 40m + 25 square units. write the expression to represent the dimensions for each side. Explain what process you use. Justify your answer.
Answer:
Each side = 4m-5
Step-by-step explanation:
16m2 - 40m + 25
factor:
(4m - 5)(4m - 5)
Each side = 4m-5
Answer:
The expression for each side = 4m - 5.
Step-by-step explanation:
We need to factor the expression for the area. As the figure is a square both factors should be identical.
16m^2 - 40m + 25:
16m^2 and 25 are both perfect squares so looks like the factors are
(4m - 5)(4m - 5)
The signs are negative because the middle term is - 40m.
If we expand the factors we get:
4m*4m - 5*4m - 5*4m -5*-5
16m^2 - 20m - 20m + 25
= 16m^2 - 40m + 25 which is the original expression, so this confirms our result.

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?
Answer:
(a) The possible dimensions are:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
(b): Patio with greatest and the least perimeter
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
Step-by-step explanation:
Given
[tex]Tiles = 72[/tex]
Solving (a): Possible rectangular models
To do this, we simply list out the possible factor pairs of 72.
So, we have:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
Solving (a): Models with the least and the greatest perimeter
Perimeter (P) is calculated using:
[tex]P = 2 * (L + W)[/tex]
So:
1 unit by 72 units;
[tex]P = 2 *(1 + 72) = 146 units[/tex]
2 units by 36 units;
[tex]P = 2 *(2 + 36) = 76 units[/tex]
3 units by 24 units;
[tex]P = 2 *(3 + 24) = 54 units[/tex]
4 units by 18 units;
[tex]P = 2 *(4 + 18) = 44 units[/tex]
6 units by 12 units;
[tex]P = 2 *(6 + 12) = 36 units[/tex]
8 units by 9 units
[tex]P = 2 *(8 + 9) = 34 units[/tex]
From the calculations above:
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
