Answer:

El móvil B necesita 60 segundos para alcanzar al móvil A y le alcanza una distancia de 2400 metros con respecto al punto de referencia.

Step-by-step explanation:

Supóngase que cada movil viaja en el mismo plano y que el móvil B se localiza inicialmente en la posición [tex]x = 0\,m[/tex], mientras que el móvil A se encuentra en la posición [tex]x = 1200\,m[/tex]. Ambos móviles viajan a rapidez constante. Si el móvil B alcanza al móvil A después de cierto tiempo, el sistema de ecuaciones cinemáticas es el siguiente:

Móvil A

[tex]x_{A} = 1200\,m+\left(20\,\frac{m}{s} \right)\cdot t[/tex]

Móvil B

[tex]x_{B} = \left(40\,\frac{m}{s} \right)\cdot t[/tex]

Donde:

[tex]x_{A}[/tex], [tex]x_{B}[/tex] - Posiciones finales de cada móvil, medidas en metros.

[tex]t[/tex] - Tiempo, medido en segundos.

Si [tex]x_{A} = x_{B}[/tex], el tiempo requerido por el móvil B para alcanzar al móvil A es:

[tex]1200\,m+\left(20\,\frac{m}{s} \right)\cdot t = \left(40\,\frac{m}{s} \right)t[/tex]

[tex]1200\,m = \left(20\,\frac{m}{s} \right)\cdot t[/tex]

[tex]t = \frac{1200\,m}{20\,\frac{m}{s} }[/tex]

[tex]t = 60\,s[/tex]

El móvil B necesita 60 segundos para alcanzar al móvil A.

Ahora, la distancia se obtiene por sustitución directa en cualquiera de las ecuaciones cinemáticas:

[tex]x_{B} = \left(40\,\frac{m}{s} \right)\cdot (60\,s)[/tex]

[tex]x_{B} = 2400\,m[/tex]

El móvil B alcanza al móvil A a una distancia de 2400 metros con respecto al punto de referencia.

Answer:

Friend your answer is 20

Step-by-step explanation:

You divide 40 by the co-efficient of 2=20

[tex]\boxed{x = 20}[/tex]

There is only one step to this equation. We use inverse operations to isolate the x by dividing 2 on both sides; because 2 is being multiplied by x, and the inverse operation for multiplication is division.

2x/2 = x

40/2 = 20

The equation now looks like:

x = 20

Step-by-step explanation:

The lobby measures 45 feet by 45 feet

Area of the lobby = 45 * 45

=2025 ft^2

So, the lobby has 2025 tiles

subtract 1 black tile in the center

2025 tiles - 1 black tile =2024 tiles

The number of blue tiles and black tiles is 2024 tiles

He wants the outer edge to be the same color as the center tile so, divide by 2

2024/2 = 1012 tiles

The number of tiles in the outer edge is 1012 tiles and the number of tiles in the center is 1012 tiles

Answer:

83 adult tickets and 217 student tickets.

Step-by-step explanation:

Let number of adult tickets sold = [tex]x[/tex]

Given that total number of tickets = 300

So, number of student tickets = 300 - [tex]x[/tex]

Cost of adult ticket = $15

Cost of student ticket = $11

Total collection from adult tickets = $[tex]15x[/tex]

Total collection from student tickets =  [tex](300-x)\times 11 = 3300-11x[/tex]

Given that overall collection = $3630

[tex]15x+(3300-11x) = 3630\\\Rightarrow 15x-11x=3630-3300\\\Rightarrow 4x = 330\\\Rightarrow x = 82.5[/tex]

So, for atleast $3630 collection, there should be 83 adult tickets and (300-83 = 217 student tickets.

Now , collection = $3632

Correct option is

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

Step-by-step explanation:

Here, we are given the line RQ, which is divided in two equal parts by a line PS which is perpendicular to RQ.

The foot S of PS is on the line RQ.

First of all, let us do a construction here.

Join the point R with P and P with Q.

Please refer to the attached image.

Now, let us consider the triangles  PQS and PRS:

Now, Two sides and the angle included between the two triangles are equal.

So by SAS congruence we can say that [tex]\triangle PRS \cong \triangle PQS[/tex]

Therefore, the corresponding sides will also be equal.

RP = QP

RP is the distance between R and P.

QP is the distance between Q and P.

Hence, to prove that P is equidistant from R and Q, we have proved that:

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

perimeter of a semicircle is [tex]\frac{2\pi r}{2}+2r=\frac{d\pi}2 +d[/tex]

$d=14$

so, perimeter= $14\cdot\frac{22}7\cdot \frac{1}2+14=22+14=36$ cm

Answer:

Perimeter of semi-circle = 36 cm

Step-by-step explanation:

diameter = d = 14 cm

Perimeter of semicircle = Circumference of semi-circle + diameter

                                       = [tex]\frac{1}{2}\pi d + d[/tex]

                                       = [tex]\frac{1}{2}*\frac{22}{7}*14 +14\\[/tex]

                                       = 22 + 14

                                       = 36 cm

Answer:

2x  5

Step-by-step explanation:

1/2(6x - 10) - x =

= 3x - 5 - x

= 2x - 5

The other side of the given equation so it's true for all values of x is 2x-5.

Given that, 1/2(6x-10)-x.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, 6x/2 - 10/2 -x

= 3x-5-2

= 2x-5

Therefore, the other side of the given equation so it's true for all values of x is 2x-5.

Answer:

b.$3170

Step-by-step explanation:

SO you would find 9% commission on 8,000

then, you would find his normal commission if he only made 35,000

so you would do 35,000x.07=2450

If (2x + 1) is a factor then x = - [tex]\frac{1}{2}[/tex] is a root and P(- [tex]\frac{1}{2}[/tex] ) = 0 ← Factor theorem

P(- [tex]\frac{1}{2}[/tex] )

Answer:

-24

Step-by-step explanation:

-3 multiply 8 = -24

Because when ever you multiply a negative number with a positive number result will always be negative and 3 multiply 8 is 24.

Answer: -24

Step-by-step explanation: When you're asked to multiply

positives and negatives together, the rules are simple.

positive times a positive is a positive

positive times a negative is a negative

negative times a positive is a negative

negative times a negative is a positive

One way that I think will help you is to think

about the problem in terms of the signs.

If the signs are the same, the product will always be positive.

For example, (+3) · (+6) = +18 and (-6) · (-2) = +12.

If the signs are different, the product is negative.

So (+6) · (-4) is -24 and (-10) · (+5) is -50.

So don't get caught up on the signs.

Do the problem first, then determine if the

signs are the same or if they are different.

Function transformation involves changing the position of a function.

The graph of g(x) is the graph of f(x) translated 2 units right, and [tex]\mathbf{g(x) = 3(x -2) + 1}[/tex]

The function is given as:

[tex]\mathbf{f(x)=3x + 1}[/tex]

The graph of g(x) passes through (2,1) and (0,-5).

Start by calculating the slope (m)

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{-5-1}{0-2}}[/tex]

[tex]\mathbf{m = \frac{-6}{-2}}[/tex]

[tex]\mathbf{m = 3}[/tex]

The equation is then calculated as:

[tex]\mathbf{g(x) = m(x -x_1) + y_1}[/tex]

So, we have:

[tex]\mathbf{g(x) = 3(x -2) + 1}[/tex]

By comparing [tex]\mathbf{f(x)=3x + 1}[/tex] and [tex]\mathbf{g(x) = 3(x -2) + 1}[/tex]

The graph of f(x) is shifted 2 units to the right

Answer:

36 lbs

Step-by-step explanation:

let the weight of each boy's backpack be B and the weight of each girl's backpack be G.

Given that the total weight of all (i.e 10 boys' and 10 girls') backpacks equals 600 lbs,  i.e.

10B + 10G = 600   (simplifying by dividing both sides by 10)

B + G = 60 ------- eq 1

Also given that a girl's backpack is 1.5 times LESS than a boy's backpack.

written another way, we can say that a boy's backpack is 1.5 times MORE than a girl's backpack, or:

B = 1.5G   (rearranging)

B - 1.5G = 0     ------ eq 2

We can solve eq 1 and eq 2 by elimination,

(eq 1) - (eq 2)

(B + G) - (B - 1.5G) = 60 - 0

B + G - B + 1.5G = 60

G  + 1.5G = 60

2.5G = 60   (divide both sides by 2.5)

G = 60 / 2.5

G = 24 lbs   (substitute this into equation 1)

B + G = 60

B + 24 = 60

B = 60 - 24

B = 36 lbs
