Answer:
93 o 39.
Explanation:
Hola.
En este caso, podemos resolver este problema por medio del planteamiento de las siguientes ecuaciones:
1. Definimos <em>x</em> como el primer dígito y <em>y</em> como el segundo, por lo tanto, como su suma es 12, escribimos:
<em>x</em> + <em>y</em> = 12
2. Ahora, dado que el primer dígito, x es el triple del segundo, escribimos:
<em>x</em> = 3 <em>y</em>
De este modo, podemos resolver para <em>y</em>:
3 <em>y</em> + <em>y</em> = 12
4 <em>y</em> = 12
<em>y</em> = 12 / 4
<em>y</em> = 3
Y para <em>x</em>:
<em>x</em> = 3 <em>y</em>
<em>x</em> = 3 * 3
<em>x</em> = 9
Así, el número puede ser 93 o 39.
¡Saludos!

Answer:
option A
Explanation:
given,
shear force = 425 N
Shear modulus = 1.7 × 10⁹ N/m²
disk equivalent to solid cylinder
height = 0.7 cm and diameter = 6.50 cm
hence, the correct answer is option A
Answer:
h = 0.288m
Explanation:
Assume
= Speed of Sue
= Speed of Chris immediately after the push
Sue's KE = 
now she swings this is converted into gravitation at PE of
mg n = 52 × 9.8 × 0.65
= 331.24
= 331.24
So, 
They started at rest by conservation of momentum in case of push off the magnitude of sue momentum and it is equal to the magnitude of Chris momentum in the opposite or inverse direction
Chris kt = 
= 220.827
220.827 = mgh
So, h = 0.288m
<span>We know that the work formula is calculated as force by distance:
W = F * d
W = 5 * 3 = 15 N*m = 15 Joules
So the work done on the object is 15 joules</span>
