A closed container has 3.06 ⋅ 10^23 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10^−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
0.47 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10−24) = 4.73 ⋅ 10−1
0.51 grams, because (3.06 ⋅ 1.67) ⋅(1023 ⋅ 10-24) = 5.1102 ⋅ 10-1
4.73 grams, because (3.06 + 1.67) ⋅ (1023 ⋅ 10−24) = 4.73
5.11 grams, because (3.06 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 5.1102
Answer:
5.11grams

Sea level is the average level of the sea between high and low tide. It is used as a reference point for measuring elevation, or height and depth, on Earth. Some places lie above sea level, while others lie below sea level.

Solve for n:
6n − 2(4n + 7) + 4 = -2
A:-6
B:-4
C:4
D:6
Answer:
B: -4
Step-by-step explanation:
In this type of situation, you should distribute -2 into the parentheses to get to this equation which is 6n - 8n - 14 + 4 = -2. Combine the two variable numbers together to get -2n and add 4 from -14 to get -10. To clean up this equation, your equation should be -2n - 10 = -2. Add 10 on both sides to get 8 on the right side and then divide -2 on both sides to get your final answer which is -4.

Which two numbers on the number line have an absolute value of 2.75? Select the location of both numbers on the number line.
the answers are: 2.75 and -2.75
absolute value is just the distance from zero on a number line
The required numbers on the number line that have an absolute value of 2.75 are 2.75 and -2.75.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
here,
Absolute values are the values that defined the distance of a number on the number line from 0. So for absolute value 2.75 we have numbers 2.75 and -2.75 both have the same distance from 0.
Thus, the required numbers on the number line that have an absolute value of 2.75 are 2.75 and -2.75.

a³x - x⁴ + a²x² - ax³
Answer:
[tex]\huge\boxed{x(a-x)(a+x)^2}[/tex]
Step-by-step explanation:
In order to factor this expression, our goal is to write the expression in a way that we can factor out a term.
With the expression [tex]a^3 x - x^4 + a^2 x^2 - ax^3[/tex], we need to note an exponent rule.
[tex]a^{b+c} = a^b a^c[/tex]
Step 1:We can use this to get each term of this expression to have a term of [tex]x[/tex] so we can factor it out.
Let's look at each term and get it so that we can factor out an x term.
[tex]a^3 x = x a^3[/tex] (Commutative Property)[tex]x^4 = xx^3[/tex] (Since [tex]x^3 \cdot x^1 = x^4[/tex])[tex]a^2 x^2 = a^2 \cdot xx[/tex] (Since [tex]x^2 = x \cdot x[/tex])[tex]ax^3 = a \cdot xx^2[/tex] (Since [tex]x^3 = x^2 \cdot x^1[/tex]With this, our equation becomes [tex](xa^3) - (xx^3) + (xxa^2) - (xx^2a)[/tex].
We now can factor out the common term x.
[tex]x(a^3 - x^3 + xa^2 - x^2a)[/tex]
Step 2:From here, we can now factor [tex]a^3 - x^3 + xa^2 - x^2 a[/tex]
Rearrange the equation: [tex]a^3 +xa^2 - x^3 - x^2a[/tex] Factor out [tex]a^2[/tex] from [tex]a^3 + xa^2[/tex] which comes out to be [tex]a^2(a+x)[/tex] Factor out [tex]-x^2[/tex] from [tex]-x^3 - x^2a[/tex] which comes out to be [tex]-x^2(x+a)[/tex] We now have [tex]a^2(a+x) - x^2(x+a)[/tex] Factor out the common term, [tex](a+x)[/tex], which comes out to be [tex](a+x)(a^2 - x^2)[/tex] Factor [tex]-x^2+a^2[/tex] into [tex](a+x)(a-x)[/tex] We now have [tex](a+x) (a+x) (a-x)[/tex], which is simplified to [tex](a-x)(a+x)^2[/tex] Finalizing:Since we have just factored [tex]a^3 - x^3 + xa^2 - x^2 a[/tex] and factored x out of [tex]a^3 x - x^4 + a^2 x^2 - ax^3[/tex] in the first couple of steps, we need to have it as a factorization of x.
[tex]x(a-x)(a+x)^2[/tex]
