3. El grupo de Mariana se organizó en seis equipos. Cada equi-
po cumplirá con tres comisiones al mismo tiempo (aseo, pun-
tualidad y orden) durante una semana. Los equipos irán par-
ticipando en orden numérico durante el primer cuatrimestre
del ciclo escolar; los turnos se iniciarán la segunda semana de
clases. Mariana es integrante del equipo 4; ¿en qué periodos
le tocará participar? ¿Todos los equipos participarán el mismo
número de veces? ¿Por qué?
Answer:
¿en qué periodos le tocará participar?
El equipo cuatro participa en el periodo 5 - 11 - 17
¿Todos los equipos participarán el mismo número de veces?
Todos los equipos los hacen 3 veces . menos 1 equipo que lo hace 2 veces
¿Por qué?
Cuatrimestre. = 120 dias
Numero de semanas = 120/ 7 17,1
17 semanas completas 3 dias
No se trabaja la primera semana. por lo que quedan 16 semana 3 dias.
Son 6 equipos para participar todos serian por lo menos 17 semanas 1 dia.
Step-by-step explanation:
Cuatrimestre. = 120 dias
Numero de semanas = 120/ 7 17,1
17 semanas completas 3 dias
No se trabaja la primera semana. por lo que quedan 16 semana 3 dias.
Son seis equipos. 17 ( 16,3) semanas / 6
Todos los equipos los hacen 3 veces . menos 1 equipo que lo hace 2 veces

Answer:
Both expression equals 5 when substituting 2 for x, because the expressions are equivalent.
Step-by-step explanation:
Given the expressions:
(1/2)x + 4
x + 6 - (1/2)x - 2
Substituting 2 for x in the equation :
(1/2)x + 4
x = 5
(1/2)2 + 4
2/2 + 4
1 + 4
= 5
x + 6 - (1/2)x - 2
Substituting 2 for x
2 + 6 - (1/2)2 - 2
8 - 2/2 - 2
8 - 1 - 2
= 5
The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum.
When d=6, T=5
Find the value of T when d=3
Input note: give your answer correct to 2 decimal place.
Answer:
[tex]T = 3.54[/tex]
Step-by-step explanation:
Given
Direct Variation of T to [tex]\sqrt d[/tex]
[tex]d =6;\ when\ T = 5[/tex]
Required
Determine T when d = 3
The variation can be represented as:
[tex]T\ \alpha\ \sqrt d[/tex]
Convert to equation
[tex]T = k\sqrt d[/tex]
[tex]d =6;\ when\ T = 5[/tex]; so we have:
[tex]5 = k * \sqrt 6[/tex]
Make k the subject:
[tex]k = \frac{5}{\sqrt 6}[/tex]
To solve for T when d = 3.
Substitute 3 for d and [tex]k = \frac{5}{\sqrt 6}[/tex] in [tex]T = k\sqrt d[/tex]
[tex]T = \frac{5}{\sqrt 6} * \sqrt{3}[/tex]
[tex]T = \frac{5\sqrt{3}}{\sqrt 6}[/tex]
[tex]T = \frac{5 * 1.7321}{2.4495}[/tex]
[tex]T = \frac{8.6605}{2.4495}[/tex]
[tex]T = 3.5356[/tex]
[tex]T = 3.54[/tex] -- approximated

A pyramid has cross-sectional shapes taken parallel to its base that are___ to one another
Answer:
The fill in the blank is the word similar.
Step-by-step explanation:
A pyramid has a cross-sectional shapes, taken parallel to its base, that are similar to one another.
When we do the cross-section of a pyramid parallel to its base, the cross-section formed will be in the same shape like the base.
Whenever a cross section is done parallel to the base of any pyramid, the resulting shape will be same like the base. As we move up in the pyramid and cross section it, the shape formed will be like the base but with smaller dimensions. But the shape will be the same as the base.
Answer: Similar

Since the x axis is the vertical side, it would be vertical. The line would also be vertical, the others are horizantal and are not vertical.
Find x - y subtracted from 0.
a. -x+y
b. -y-x
c. x-y
{6x+6y=18
{2x-6y=-10
Answer:
x = 1, y = 2
Step-by-step explanation:
this system is set up nicely to just add because then the y-value will be eliminated and you will have:
8x = 8
x = 1
get y value: 2(1) - 6y = -10
2 - 6y = -10
-6y = -12
y = 2

Which equation has infinitely many solutions?
A.
-5(x + 2) = -4x- 12 - X + 2
B.
3x- 4 + 2x = 5(x-4)
c. 5(x + 7) = -5(x-7)
D
6x+ 2 - X=-2x - 2 + 7x
Answer:
A. -5(x + 2) = -4x - 12 - x + 2
Step-by-step explanation:
The equation that has infinitely many solutions will be the same on both sides.
A is the correct answer.
Simplify the equation by distributing -5 and adding like terms:
-5(x + 2) = -4x - 12 - x + 2
-5x - 10 = -4x - 12 - x + 2
-5x - 10 = -5x - 10
So, this equation is the same on both sides and will have infinitely many solutions.
A is the correct answer.
Answer:
A has infinitely many solutions
Step-by-step explanation:
Once you distribute A you get
-5x-10= -4x-12-x+2
Once you simplfy all that you get
-5x-10= -5x-10
You can check this by putting in a random number and both sides will be equal.

What is a Triangle?A triangle is a polygon with three sides, vertices and angle.
Triangle A B C is cut by line segment M N.
such that,
A M = M B = 88 centimeter
CN =NB = 75 centimeter
AC = 116 centimeter
If a line segment joins the mid-points of two sides of a triangle, then the line segment is parallel to the third side of the triangle and the measure is equal to half of its length.
MN = (1/2) AC
MN = (1/2) * 116

If g(x) is the inverse of f(x) and f (x) = 4 x + 12, what is g(x)?
Answer:
[tex]let \: the \: inverse \: of \: f(x) \: be \: m \\ m = {f(x)}^{ - 1} \\ m = {(4x + 12)}^{ - 1} \\ m = \frac{1}{(4x + 12)} \\ m(4x + 12) = 1 \\ 4x = \frac{1}{m} - 12 \\ x = \frac{1}{4m} - 3 \\ therefore \\ g(x) = \frac{1}{4x} - 3[/tex]
Answer:
g(x) = 1/4 x -3
Step-by-step explanation:
f (x) = 4 x + 12
g(x) = f⁻¹(x)
step 1: re-write as linear equation y = 4x+12
step 2: swap x and y x = 4y + 12
step 3: solve y 4y = x - 12 y = 1/4 x -3
step 4: inverse notation: f⁻¹(x) = 1/4 x - 3 i.e. g(x) = 1/4 x -3

1. Factor the polynomial. (2 polnts)
-3x4 - 9x3 + 15x2
2. Use the grouping method to factor the polynomial below completely. (4 points)
10x3 - 35x2 + 6x - 21
Answer: 1. 3x^2(-x^2-3x+5). 2. (2x-7)(5x^2+3)
Step-by-step explanation:
(1) Find the greatest common factor - 3x^2. Simplify as much as possible.
(2) Split 10x^3 - 35x^2 and 6x-21 into two separate groups. Factor each group separately to get 5x^2(2x-7) and 3(2x-7). The numbers in the parentheses should be the same for each group - (2x-7). Take the numbers outside of the parentheses and put them together to get (5x^2+3). Your final answer will be (2x-7)(5x^2+3).
1. The required factor of the polynomial is
(-3x²)(x²+3x-5).
2. The required factor of the polynomial using grouping method, the answer is (5x²+3)(2x-7).
What is a polynomial?"A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables."
What is factorization of a polynomial?"The factorization of polynomials or polynomial factorization expresses a polynomial with coefficients in a given field or in the integers as the product of irreducible factors with coefficients in the same domain.
There are six different methods to factorizing polynomials. One of those methods is factorization of a polynomial by grouping method."
1. The given polynomial is
[tex]-3x^{4} - 9x^{3} + 15x^{2} \\= - 3x^{2}(x^{2}+3x-5)\\[/tex]
Therefore, by factorizing the given polynomial, we get:
[tex]- 3x^{2}(x^{2}+3x-5)[/tex].
2. The given polynomial is
[tex]10x^{3}-35x^{2} +6x-21[/tex]
We need to factorize it using grouping method.
Therefore,
[tex]10x^{3}-35x^{2} +6x-21\\= 5x^{2}(2x-7)+3(2x-7)\\= (5x^{2} +3)(2x-7)[/tex]
Hence,
1. The required factor of the polynomial is
(-3x²)(x²+3x-5).
2. The required factor of the polynomial using grouping method, the answer is (5x²+3)(2x-7).
