Conocido popularmente como el Lanzón, es una escultura elaborada por la cultura Chavín de Perú. Este gran monolito data, aproximadamente, del año 1000 a. C. y está situado en el Viejo Templo del centro religioso y ceremonial de Huantar.
Cierto día en una visita cultural, Pedro decide representar el Lanzón Monolítico con una escala de 1:103 cuya medida es de 4,41 cm.
Teniendo en cuenta los datos de la situación. ¿Cuánto mide la altura real exacta del Lanzón en metros?
Answer:
La altura real del Lanzón Monolítico es de 453.23 centímetros, o 4.53 metros.
Step-by-step explanation:
Dado que la representación a escala del Lanzón Monolítico mide 4,41 centímetros, y que dicha escala tiene un valor de 1:103 respecto de la medida real de la escultura, para representar la altura real de la misma se requiere realizar el siguiente cálculo:
1 = 4,41
103 = X
(103 x 4,41) / 1 = X
454.23 = X
Por lo tanto, la altura real del Lanzón Monolítico es de 453.23 centímetros, o 4.53 metros.
Norman purchased 3.5 lb. Of his favorite mixture of dried fruits to use in a trail mix. The total cost was $16.87. How much does the fruit cost per pound?
Answer:
$4.82
Step-by-step explanation:
Given that:
The total cost of the fruit is $16.87
And Norman purchased 3.5 lb of his favorite mixture of dried fruits.
The cost of the fruit per pound can be calculated by dividing the total cost of fruit by the total amount of pounds of fruit purchased.
i.e.
The cost of the fruit per pound = $16.87/3.5
The cost of the fruit per pound = $4.82

Orchestra Tonight is selling tickets for its local performance. Orchestra fans can buy tickets to sit in the balcony or on the floor of the concert hall. Tickets for floor seats are $83 each. Tickets for the balcony are 60% of the price of the floor tickets. Which inequality represents all possible combinations of f, the number of tickets for floor seats, and b, the number of tickets for balcony seats, that a person can buy and spend no more than $560?
Answer:
[tex]83f+49.8b \leq 560[/tex]
Step-by-step explanation:
Given that the cost of 1 floor ticket = $ 83.
Cost for f floor tickets = $ 83f
Ticket for 1 balcony ticket = 60% of floor ticket.
= 0.60 x 83 = $49.8
Cost for b balcony tickets = $ 49.8b.
Total cost for f floor tickets and b balcony tickets, C= 83f+49.8b.
As the person can spend a maximum of $560,
So, [tex]C\leq 560[/tex]
[tex]\Rightarrow 83f+49.8b \leq 560[/tex].
Hence, the required inequality is [tex]83f+49.8b \leq 560[/tex].

If there are 420 students surveyed, which equation can be used to find the number of students s who prefer rap? Pop: 5/8 Jazz: 1/8 Rap: 1/4 Answers: A. 1/4s = 420 B. S = 1/4 * 420 C. S + 1/4 = 420 D. 420 + s = 1/4
Answer:
B. [tex]s=\dfrac{1}{4}\times420[/tex]
Step-by-step explanation:
Total number of students surveyed = 420
Of which only [tex]\dfrac{1}{4}[/tex] prefer rap.
So, the number of people who like rap is the product of the fraction of people who prefer rap and the total number of students.
[tex]\text{Number of students who prefer rap}=s=\dfrac{1}{4}\times420\\\Rightarrow s=105[/tex]
The number of students that prefer rap is 105
So the equation is [tex]s=\dfrac{1}{4}\times420[/tex].

Una antena de televisión será sujeta con un cable de 6 m de longitud de la parte superior de la misma, a una argolla que se encuentra en el piso de la azotea, con un ángulo de inclinación de 60° con respecto al piso, ¿qué longitud tiene la antena?
Answer:
5.196 m
Step-by-step explanation:
p = La perpendicular del triángulo es la longitud de la antena.
h = La hipotenusa del triángulo es la longitud del cable conectado a la parte superior del poste = 6 m
[tex]\theta[/tex] = Incline el cable con el suelo = [tex]60^{\circ}[/tex]
De las funciones trigonométricas sabemos que
[tex]\sin\theta=\dfrac{p}{h}\\\Rightarrow p=h\sin\theta\\\Rightarrow p=6\times \sin60^{\circ}\\\Rightarrow p=6\times\dfrac{\sqrt{3}}{2}\\\Rightarrow p=3\sqrt{3}\\\Rightarrow p=3\times 1.732=5.196\ \text{m}[/tex]
La longitud de la antena es 5.196 m.

Nana plants 3 red roses bushes for every 4 yellow rose bushes in her garden. If she plants 12 red rose bushes, how many yellow will she plant? Number only
Answer:
16
Step-by-step explanation:
Given that:
For every 3 red roses bushes for every 4 yellow bushes are planted by Nana in her garden.
Let us first have a look at the ratio of red roses bushes and yellow bushes.
Number of red roses bushes : Number of yellow bushes = 3 : 4
Now, we are given that there are 12 red rose bushes planted.
To find: How many yellow rose bushes Nana will plant?
Solution:
Let us use unitary method for finding the required answer.
Number of yellow rose bushes for every 3 red roses = 4
Number of yellow rose bushes for every 1 red rose = [tex]\frac{4}{3}[/tex]
Number of yellow rose bushes for every 12 red rose = [tex]\frac{4}{3}\times 12 = 4\times 4 = \bold{16}[/tex]
Therefore, the answer is 16.

Simplify: (2a)(-5b)
?
Answer:
-10ab
Step-by-step explanation:
(2a)(-5b)
Multiply the constants
2* -5 = -10
Multiply the variables
a*b = ab
Combine
-10ab
The expression -10ab represents the product of 2a and -5b
To simplify the expression (2a)(-5b), we can multiply the coefficients and combine the variables.
Multiplying the coefficients, 2 and -5, gives us -10.
For the variables, we multiply the like terms, which in this case are 'a' and 'b'. When we multiply 'a' and 'b', we simply write them side by side: ab.
Therefore, simplifying (2a)(-5b) results in -10ab.
The expression -10ab represents the product of 2a and -5b, combining the coefficients and variables into a single term. It is important to note that the order of the variables, 'a' and 'b', is maintained in the simplified form.

Rational numbers are numbers that can be written in the form of a/b where a and b are integers. The best correct name for the set of numbers (...,-3-2-10,1,2,3,...) are integers.
What is a rational number?Rational numbers are numbers that can be written in the form of a/b where a and b are integers.
Example: 1/2, 3.5 (which is writable as 7/5), 2(which is writable as 4/2), etc.
The best correct name for the set of numbers (...,-3-2-10,1,2,3,...) are integers. Since integers are in the category of rational numbers, while rational numbers are in the category of real numbers.
Therefore, The correct name for the set of numbers (...,-3-2-10,1,2,3,...) can be either integer, rational numbers, or real numbers. But since rational numbers and real numbers are too wide, thus, the best answer choice will be integers.
Hence, The best correct name for the set of numbers (...,-3-2-10,1,2,3,...) are integers.
