Answer:

1) The forming of a theory or conjecture without firm evidence. Or, investment in stocks, property, or other ventures in the hope of gain but with the risk of loss.

2) Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another. There are multiple ways this can occur. The natural ways speciation can occur are allopatric, parapatric, and sympatric speciation.

3) Before the Great Depression, there were limited regulations that governed the stock market. Investors were able to speculate wildly and buy stocks on margin or using borrowed money. ... The poor policies that governed the stock market proved to be another of the causes of the Great Depression.

I think 1 and 2 might be wrong but, hope it helped!

Fine-grained clastic rocks are ______. Multiple choice question. easily eroded eroded with difficulty eroded with drastically di

AnnZ [28]

A property of fine-grained clastic rocks is that they are easily eroded.

<h3>Why are these rocks easily eroded?</h3>

Fine-grained clastic rocks have small fragments and grains which make them lighter than other rocks.

As a result they are more susceptible to weathering which then allows them to be easily carried off by water or air.

In conclusion, option A is correct.

BD is the angle bisector of ZABC

Thepotemich [5.8K]

Answer:

x = 7, y = 2

Explanation:

Two triangles are said to be congruent if all three sides and three angles of one triangle is equal to three sides and three angles of the other triangle.

From the question:

BD ≅ BD (reflexive property of equality)

Since BD is the angle bisector of ∠ABC, hence ∠ABD = ∠CBD

∠ABD = 2x + y, ∠CBD = 14 + y. Therefore:

2x + y = 14 + y

2x = 14 + y - y

2x = 14

x = 14 / 2

x = 7

Also, ∠BAD = ∠BCD = 90° (right angled triangle)

Since ∠BAD = ∠BCD, BD ≅ BD and ∠ABD = ∠CBD, therefore ΔABD is congruent to ΔCBD by angle-angle-side congruence theorem.

The angle-angle-side congruence theorem states that if two angles and one side of one triangle is equal to two angles and one side of another triangle the both triangles are congruent.

ΔABD is congruent to ΔCBD, therefore AD = CD

5x - y = x + 13y

13y + y = 5x - x

14y = 4x

14y = 4(7)

y = 4(7) / 14

y = 2
