Type the number 1340000 in scientific notation. express your answer using scientific notation.

Answers

Answer 1
The answer is 1.34 X 10^ 6, It is 1.36 times ten to the sixth power
Answer 2
Final answer:

To convert the number 1,340,000 into scientific notation, move the decimal point 6 places to the left to get 1.34, then place this as an exponent on 10 to get 1.34 x 10^6.

Explanation:

In scientific notation, large numbers are simplified by moving the decimal point to the left until we have a number between 1 and 10. We then use an exponent on 10 to indicate how many places the decimal point has been moved. If you take a look at the number 1,340,000, the decimal point is technically at the end of the number right now. In order to express this number in scientific notation, we move the decimal point 6 places to the left, which gives us 1.34. The number of places we moved the decimal point to the left becomes the exponent on 10. Therefore, 1,340,000 in scientific notation is 1.34 x 10^6.

Country A produces about eight times the amount of diamonds in carats produced in country B. If the total produced in both countries is 9,000,000 carats, find the amount produced in each country

Answers

that would be 9,000,000,000 times 8, wich is 72,000,000,000. Because 9*8 is 72 excepts theres a 9 million.
Let X = # carats produced in country B.
Then A + B = 8B + B = 9000000  9B = 9000000
B = 1000000
A = 8xB = 8000000

What is an expression?

Expression in mathematics is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Let the two numbers be x and y respectively. Now let corelate the statement given in question :

One positive number is 1/5 of another number which  means x=(1/5) y

and, it is also given that the difference between the two numbers is 60 which means y -x = 60. Now solving these question by substitution method.

y-x = 60

5x-x= 60

4x = 60

x = 15

y = 75

Therefore, the two positive numbers are 15 and 75 respectively.

Any proposed solution of a rational equation that causes a denominator to equal​ _______ is rejected.

Answers

Answer:

Any proposed solution of a rational equation that causes a denominator to equal​ __ZERO__ is rejected.

Step-by-step explanation:

We will show this statement is true by an example:

Consider the expression :  [tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

Now, solved the rational expression and check its proposed solution

[tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

x cannot equal to 4, as it makes  both denominators equal to zero.

Multiply both the sides by (x-4),

[tex]\left ( x-4 \right )\cdot \frac{x}{x-4}=\left (x-4 \right )\cdot\left ( \frac{x}{x-4}+4  \right )\\[/tex]

Now, use the distributive property on Right hand side,

[tex]\left ( x-4 \right )\cdot \frac{x}{x-4}=\left (x-4 \right )\cdot \left ( \frac{x}{x-4} \right )+\left (x-4 \right )\cdot 4\\[/tex]

Simplify the above expression,

[tex]x=x+4x-16[/tex]

Combine like terms,

[tex]x-x-4x=-16[/tex]

[tex]-4x=-16[/tex]

Divide both sides by -4, we get

[tex]\frac{-4x}{-4}=\frac{-16}{-4}[/tex]

[tex]x=4[/tex].

As we know that x cannot equal to 4, replacing x=4 in the original expression causes the denominator equal to 0.

Check the solution: [tex]\frac{x}{x-4}=\frac{x}{x-4}+4[/tex]

Substitute the value of x=4 in the original expression,

[tex]\frac{4}{4-4}=\frac{4}{4-4}+4[/tex]

[tex]\frac{4}{0}=\frac{4}{0}+4[/tex]

Thus, 4 must be rejected as the solution, and the solution set is only 0.












Final answer:

A proposed solution of a rational equation that causes a denominator to equal zero is rejected because division by zero is not possible.

Explanation:

Any proposed solution of a rational equation that causes a denominator to equal zero is rejected. When the denominator of a rational equation is zero, the fraction becomes undefined because division by zero is not possible. In mathematics, division by zero is an undefined operation.

In October Greg and Thomas had the same amount of money in their savings account in November Greg deposited $120 into his account Thomas increased the money in his account by 20% when they compare their bounces they found out they were still equal

Answers

assume the amount of money they both deposited in october is m.
in november, greg deposited 120$, so the total amount in his account became m+120
thomas increased his account by 20%, this meams that the amount of money in his account became: m+0.2m
since both values are still equal, we will equate the two equations and solve for m:
m+120 = m+0.2m
0.2m = 120
m = 600$


The ordered pair (–2, –4) is a solution of which system?

Answers

its just a matter of subbing....and for it to be a solution, it has to satisfy both inequalities.

y < = x + 2....(-2,-4)....x = -2 and y = -4
-4 < = -2 + 2
-4 < = 0 (true)

y > = x - 3.....(-2,-4)...x = -2 and y = -4
-4 > = -2 - 3
-4 > = -5 (true)

ur answer is the last one


The given ordered pair is the solution of y ≤ x + 2 and y ≥ x - 3. Option E is correct.

As of the given numeral, The ordered pair (–2, –4) is a solution of which system is to be determined.

What is inequality?

Inequality is defined as the relationship of an equation containing the symbol ( ≤, ≥, <, >) instead of the equal sign.

here,
(–2, –4) is a solution of y ≤ x + 2 and y ≥ x - 3,
Proof,
Substitute this ordered paired in the inequality,

-4 ≤ -2 + 2
-4 < 0
and
-4 ≥ -2 - 3
-4 > -5

Thus,  the ordered pair supplied is the solution of y x + 2 and y x - 3. Option E is the right answer.

what is The cost per unit?

Answers

The cost per unit is the total expenditure incurred by a company to produce, store and sell one unit of a particular product or service. Unit costs include all fixed costs, and all variable costs, involved in production.

To figure your total manufacturing cost per unit, divide your total costs by the total number of units produced. For example, say for the year your company made 1 million units and incurred production costs of $3 million. Divide your $3 million costs by the 1 million units to find your cost per unit: $3.
