8 0

Answer: -21/7 or -3 (depends on your instruction)

Explanation:

Opposite: the opposite of the current sign

  • if it is currently negative [-], then its opposite is positive [+]
  • If it is currently positive [+], then its opposite is negative [-]

Reciprocal: changing the place of numerator and denominator

  • The reciprocal of a/b is b/a

---------------------------------------------------

7/21

Opposite: since it is positive, the opposite is negative

Reciprocal: since it is 7/21, we change the place, and it is 21/7=3

<h2>Opposite reciprocal of 7/21 is -21/7 or -3</h2>

a fault is found that cuts through lower rock layers but not those above it. which can most likely be concluded?​
grin007 [14]

The fault is younger than the lower rocks but older those above it.

Explanation:

A fault found that cuts through lower rock layers but not those above it suggests that the fault is younger than the lower rock but older than those above it.

This interpretation is based on the principle of cross-cutting which states that "an intrusion or fault is younger than the rocks they cut through".

  • In essence, an intrusion or fault cannot cut through a rock sequence unless it is already in place.
  • This is why the fault that cuts through the rock layers is younger than the rock layers.
  • But since it did not pass through the layers above, it is older than it.

Why can category 1 tropical cyclones be more destructive than category 5 tropical cyclones?
Arturiano [62]

When dealing with the degree of cyclones we have to consider the place where a cyclone can occur.

<h3>Why does a Grade 1 cyclone have more consequences?</h3>

This is due not only to the degree of the cyclone but where it occurs, so a cyclone of degree 1 in a city will have infinitely greater consequences than a hurricane of 5 in the middle of the ocean.
