Answer:
Step-by-step explanation:
Let the time taken by the john to get to his uncle be x.
Let the time taken by the john to get back from his uncle be y.
So,
x+y=12 ------ equation 1
According to the given velocities:
20x=30y
x=3/2y
Put the value x=3/2y in equation 1
3/2y+y =12
3y+2y/2=12
3y+2y=12*2
5y=24
y=24/5
y=4.8h
Now put the value of y in x=3/2y
x=3/2*4.8
x=14.4/2
x=7.2h ....
Answer:

Answer: (x, y) transforms into (-x, y)
Step-by-step explanation:
When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.
So if we do a reflection over the y-axis, then the value of y must be fixed.
So if we start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)
So the rule is, the y value remains equal and the x changes of sign.
La medida aproximada del lado faltante según el teorema de desigualdad de triángulos es:
- más de 12 cm y menos de 48 cm
De acuerdo con el teorema de la desigualdad del triángulo que establece que;
La suma de la longitud de 2 lados cualesquiera de un triángulo debe ser mayor que el tercer lado.
Dado que :
a = 30 cm; b = 18 cm; c =?
Basado en el teorema de la desigualdad del triángulo;
- c debe ser <(a + b)
- c <(30 + 18); c <48 cm
- También c> (a - b)
- c> (30 - 18); c> 12 cm
Por lo tanto, el lado faltante debe ser menor que 48 y mayor que 12.
