Answer: X=3

Because if you subtract 13 on that side you’ll be left with 4X equals 12 then you divide on both sides and that will x equal three

Una lancha que viaja a 10 m/s pasa por debajo de un puente 3 segundos después que ha pasado un bote que viaja a 7 m/s, ¿después

ExtremeBDS [4]

Answer:

La lancha y el bote se encontrarán a 70 metros de distancia del puente.

Step-by-step explanation:

Sea el punto debajo del puente el punto de referencia y que ambas lanchas se desplazan a velocidad a continuación, las ecuaciones cinemáticas para cada embarcación son presentadas a continuación:

Bote a 7 metros por segundo

$x_{A} = x_{o}+v_{A}\cdot t$ (Ec. 1)

Lancha a 10 metros por segundo

$x_{B} = x_{o}+v_{B}\cdot (t-3\,s)$ (Ec. 2)

Donde:

$x_{o}$ - Posición debajo del puente, medido en metros.

$x_{A}$ , $x_{B}$ - Posición final de cada embarcación, medido en metros.

$v_{A}$ , $v_{B}$ - Velocidad de cada embarcación, medida en metros por segundo.

$t$ - Tiempo, medido en segundos.

Para determinar la posición en la que ambas embarcaciones se encuentran, se debe determinar el instante en que ocurre a partir de la siguiente condición: $x_{A} = x_{B}$

Igualando (Ec. 1) y (Ec. 2) se tiene que:

$v_{A}\cdot t = v_{B}\cdot (t-3\,s)$

Ahora despejamos el tiempo:

$3\cdot v_{B} = (v_{B}-v_{A})\cdot t$

$t = \frac{3\cdot v_{B}}{v_{B}-v_{A}}$

Si sabemos que $v_{B} = 10\,\frac{m}{s}$ y $v_{A} = 7\,\frac{m}{s}$ , entonces:

$t = \frac{3\cdot \left(10\,\frac{m}{s} \right)}{10\,\frac{m}{s}-7\,\frac{m}{s}}$

$t = 10\,s$

Ahora, la posición de encuentro es: ( $x_{o} = 0\,m$ , $v_{A} = 7\,\frac{m}{s}$ y $t = 10\,s$ )

$x_{A} = 0\,m + \left(7\,\frac{m}{s} \right)\cdot (10\,s)$

$x_{A} = 70\,m$

La lancha y el bote se encontrarán a 70 metros de distancia del puente.

Point G is the center of the small circle. Point X is the center of the large circle. Points G, Y, and X are all on line segment

Rama09 [41]

The answer
if Marco wants to create a new circle using GX as a radius,
so GX = r = 10 cm + 16 cm = 26 cm
the area of a circle is

A = pie x r², so the new circle's area should be A = pie x 26² = 676 pie cm²
the true answer is

D. 676 pie cm2

10 times as much as blank hundred is 70 hundreds or blank thousands

netineya [11]

Answer:

10 times as much as 7 hundred is 70 hundreds or 7 thousands.

Step-by-step explanation:

The question given is:

10 times as much as _____ hundreds is 70 hundreds or _____ thousands.

Dividing the question into two fractions, we have:

10 times what is 70 hundreds?

What is 70 hundreds in thousands?

10 x 7 hundred = 10 x 700 = 70 hundreds

Recall that 70 hundreds = 70 00

70 hundreds = 70 00 = 7 thousands = 7 000

Therefore, the question can be written as:

10 times as much as 7 hundreds is 70 hundreds or 7 thousands.
