Deficits lead the US dollar to weaken, productivity to plummet, and the nation must spend within its production possibilities curve, all of which are consequences of big US trade deficits. Option D is correct.
What is the trade deficits?A trade deficit, also known as a negative balance of trade, occurs when a country spends more money than it earns in international commerce with the rest of the world.
U.S. productivity is falling, The nation must consume within its production possibilities curve. Deficits weaken the US dollar, reduce productivity, and force the country to spend inside its production possibilities curve, all of which are effects of large US trade deficits.
When a country purchases more than it sells, it has a trade imbalance. In other terms, a trade imbalance occurs when a country buys more than it exports.

a triangle has angles that measure (x+40), (3x +20), and (10x-20) respectively. which of the following terms best describes this triangle?
Answer:
Isoceles
Explanation:
Had it on my test
The term that best describes the given triangle is known as Isosceles. Thus, the correct option for this question is C.
What do you mean by Isosceles triangle?An Isosceles triangle may be defined as a type of triangle in which two sides have the same length. With respect to the length of the sides, the angles opposite to the two sides correspond to each other and are also always equal.
According to the question,
The angles of a triangle are determined by the following concept:
x+40 + 3x+20 + 10x-20 = 180.
14x + 40 = 180.
14x = 180 - 40 = 140, x = 10.
Now, the angles are 50, 50, and 80.
Two angles are equal which means two sides are definitely equal.
Therefore, an isosceles is a term that best describes the given triangle. Thus, the correct option for this question is C.

Answer:
Knowing that a simile is a comparison between two things/ideas using the words "like" or "as"--->
A roller coaster can feel like flying because similar to how you would imagine flying to feel like (almost free-falling, liberated, vulnerable, yet invigorating, etc.), a roller coaster enables you to feel the same way, you are high up in the air racing at fast speeds and looping in some way that somehow defies the laws of physics ✨ yes fun stuff
Essentially, roller coasters can feel like flying because flying and roller coasters give the same feelings of excitement and also being high up in the air, since being on the ground won't take ya anywhere.

Answer:
Sinkholes is the correct answer.
A byproduct of both chemical and physical weatherization is: 2. Soil.
Weathering can be defined as both the chemical and physical breakdown of a rock into smaller fragments (pieces) that are referred to as sediments.
Generally, there are two (2) main types of weathering and these are;
Physical weatheringChemical weatheringSoil formation occur mainly as a result of the process of both the chemical weathering of minerals and physical weathering of rocks, especially when in contact with living organism, air, climate, wind and water.

Probability = n(E)/n(S)
where:

Is the author of the article suggesting that the influence of department stores can no

answer?
A No; Over the years, women became the primary consumers for their families, and
brands started to vie for their attention and their dollars.
B Yes, In pically, though, the department stores that helped turn women into shopping
powerhes with a spending power of up to $20 trillion worldwide may be in their
waning days.
C Yes; As legacy retailers like JCPenney and Sears shutter, the days of glamorous
showcase shopping seem far away.
D No; But the freedom they helped to give women has only grown - and these days, a
woman doesn't even have to leave the house to flex her consumer power.
The answer choice from the article which BEST supports the inference that the influence of department stores can no longer be seen in society is the statement that even though the department stores although once powerful worldwide may be in their waning days.
As a result of this, we can see that from the list of available options, there is the obvious choice to show that the inference that the department stores which were once powerful and was a favorite destination for shopping could be on decline and their influence greatly reduced.

For the expression:
(9x^2 + 4y^2 -12xy) / (4y^2 - 9x^2)
Find the domain
Find the domain of the simplified expression
The domain of an expression is the set of input values the expression can take
The domain of the expression is [tex]y \ne 1.5x[/tex]The domain of the simplified expression is [tex]y \ne -1.5x[/tex](a) The domain of the expression
The expression is given as:
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)}[/tex]
Set the denominator to 0, to determine the domain
[tex](4y^2 - 9x^2) = 0[/tex]
Remove brackets
[tex]4y^2 - 9x^2 = 0[/tex]
Add 9x^2 to both sides
[tex]4y^2 = 9x^2[/tex]
Divide both sides by 4
[tex]y^2 = 2.25x^2[/tex]
Take positive square roots of both sides
[tex]y = 1.5x[/tex]
Hence, the domain of the expression is [tex]y \ne 1.5x[/tex]
(b) The domain of the simplified expression
The expression is given as:
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)}[/tex]
Rewrite as:
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(9x^2 - 12xy+ 4y^2 )}{((2y)^2 - (3x)^2)}[/tex]
Expand the numerator
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(9x^2 - 6xy - 6xy+ 4y^2 )}{((2y)^2 - (3x)^2)}[/tex]
Factorize the numerator
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{3x(3x - 2y) - 2y(3x- 2y )}{((2y)^2 - (3x)^2)}[/tex]
Factor out 3x - 2y
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(3x - 2y)(3x- 2y )}{((2y)^2 - (3x)^2)}[/tex]
Express the denominator as a difference of two squares
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{(3x - 2y)(3x- 2y )}{(2y - 3x)(2y + 3x))}[/tex]
Rewrite as:
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{-(2y - 3x)(3x- 2y )}{(2y - 3x)(2y + 3x))}[/tex]
Cancel out the common term
[tex]\frac{(9x^2 + 4y^2 - 12xy)}{(4y^2 - 9x^2)} = \frac{-(3x- 2y )}{(2y + 3x)}[/tex]
Set the denominator to 0, to determine the domain
[tex]2y + 3x= 0[/tex]
Subtract 3x from both sides
[tex]2y= -3x[/tex]
Divide both sides by 2
[tex]y= -1.5x[/tex]
Hence, the domain of the simplified expression is [tex]y \ne -1.5x[/tex]
