What is the data table?
Table is a way to represent the data of the two or more variable. To read the data from the table look for the value of one variable, and get the resultant value of other variable from the corresponding block.
Suppose that the countries of Brazil, Argentina, Ecuador, and Venezuela have interdependent economies.
The following table shows the imports and exports between each of these countries.
All prices given in millions of equivalent US dollars.
The trade of all the countries can be calculated as,
Brazil Argentina 4,691, Brazil Ecuador 4,791, Brazil Venezuela 1,526
[tex]B=4,691 +4,791 +1,526 =11008\rm millon[/tex]

Venezuela Brazil 4,535 Venezuela Argentina 1,577 Venezuela Ecuador 1,871
[tex]V=4,535 +1,577 +1,871=7983\rm million[/tex]
The highest trade is for Brazil and lowest is for Argentina. The difference between two is,
[tex]d=11008-6005\\d=5003\rm million[/tex]
The difference between the highest balance of trade and the lowest balance of trade is $500,300,000.

Answer:
D. (11x + 8y) (11x - 8y)
Step-by-step explanation:
Step 1: Rewrite 121x² - 64y² as (11x)² - (8y)²
Step 2: The difference of squares can be factored using the rule:
a² - b² = (a - b) (a + b)
(11x - 8y) (11x + 8y)

find the value of x in the figure.
Answer:
50°
Step-by-step explanation:
The blue lines form a Right-angled triangle.
*Such triangles have one angle equal to 90°.*
*Property*
Sum of all angles in a triangle = 180°
To find :
Value of x – an angle of the right-angled triangle.
Solution:
==> 90 + 40 + x = 180
==> 130 + x = 180
isolating x
==> x = 180 - 130
==> x = 50°

Write an inequality that describes all the points that are more than 3 units from 5.
x>8 and x<2 are the two possible inequalities of |x - 5| > 3
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Let x be the number
|x - 5| > 3
Now solve for x.
Suppose x - 5 is positive. Then
x - 5 > 3
x > 8
Suppose x - 5 is negative. Then |x - 5| = -(x - 5) = 5 - x
5-x>3
5-3>x
2>x
x<2
Hence, x>8 and x<2 are the two possible inequalities of |x - 5| > 3

Step-by-step explanation:
all you need to do is move the decimal point over 5 times but this will only work if your multiply by 10 and that it has a negative exponent
The number 6.38×10⁻⁵ written in ordinary form is 1/638000.
What is scientific notation?In scientific notations numbers are written in the form of a base that is
0 ≤ b < 10 and multiplied by 10ⁿ where n represents integers.
We write large standard numbers in scientific form in a compact manner.
Given, A number in scientific form as 6.38×10⁻⁵.
Now, We know an exponent must be written as a positive value.
Therefore,
6.38×10⁻⁵.
= 1/ 6.38×10⁵.
Now, The ordinary form of the number is when we write without the exponent.
So,
1/ 6.38×10⁵ is,
