Answer:
because they are the rocks that line the surface of our planet
Explanation:
We see sedimentary rocks more than other rock types because they are the rocks that line the surface of our planet.
Sedimentary rocks typically form the earth cover due to the way they are formed.
- These rocks are produced by the weathering, transportation and deposition of sediments within a basin.
- In this basin, the sediment is lithified and converted to sedimentary rocks.
- These processes are driven by the external heat engine
- Therefore, it is confined to the surface.
- Igneous and metamorphic rock's processes are confined to the subsurface.

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:
<h2>a)
Acceleration is 3.09 m/s²</h2><h2>
b) Distance traveled is 45.05 m</h2><h2>c)
Time taken to travel 250 m is 12.72 s</h2>
Explanation:
a) We have equation of motion v = u + at
Initial velocity, u = 0 km/hr = 0 m/s
Final velocity, v = 60 km/hr = 16.67 m/s
Time, t = 5.4 s
Substituting
v = u + at
16.67 = 0 + a x 5.4
a = 3.09 m/s²
Acceleration is 3.09 m/s²
b) We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 0 m/s
Acceleration, a = 3.09 m/s²
Time, t = 5.4 s
Substituting
s = ut + 0.5 at²
s = 0 x 5.4 + 0.5 x 3.09 x 5.4²
s = 45.05 m
Distance traveled is 45.05 m
c) We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 0 m/s
Acceleration, a = 3.09 m/s²
Displacement, s = 0.25 km = 250 m
Substituting
s = ut + 0.5 at²
250 = 0 x t + 0.5 x 3.09 xt²
t = 12.72 s
Time taken to travel 250 m is 12.72 s
