B. 0.3^3 is just 0.3 times itself 3 times. We can right it as 0.3 x 0.3 x 0.3 -> 0.09 x 0.3 -> 0.027
Step-by-step explanation:
Hope this helps :)
0.3^3 is just 0.3 times itself 3 times. Thus, 0.027 option 2 is correct.
What are some basic properties of exponentiation?If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}[/tex]
We can right it as;
0.3 x 0.3 x 0.3
= 0.09 x 0.3
= 0.027
Therefore, 0.3^3 is just 0.3 times itself 3 times. Thus, 0.027 option 2 is correct.

Find the solution set for this inequality, -2x + 4 > -4x + 8
Answers
Answer:
The answer is
x > 2Step-by-step explanation:
- 2x + 4 > - 4x + 8
Add 4x to both sides of the inequality
That's
- 2x + 4x + 4 > - 4x + 4x + 8
2x + 4 > 8
Subtract 4 from both sides
That's
2x + 4 - 4 > 8 - 4
2x > 4
Divide both sides by 2
That's
[tex] \frac{2x}{2} > \frac{4}{2} [/tex]
We have the final answer as

Solve for s.
0.5s +1= 7+ 4.58
S =?
Answers
Answer:
s = 21.16
Step-by-step explanation:
0.5s +1= 7+ 4.58
Combine like terms
0.5s +1=11.58
Subtract 1 from each side
0.5s +1-1= 11.58-1
.5s = 10.58
Multiply by 2
.5s *2 = 10.58*2
s = 21.16
Answer: s = 21.16
Step-by-step explanation:
0.5s + 1 = 7 +4.58 Combine like terms on the right side
0.5s + 1 = 11.58 Subtract 1 from both sides
-1 -1
0.5s = 10.58 Divide both sides by 0.5
s = 21.16
To factor 9x^2 - 4, you can first rewrite the expression as:

B. (x)^2 - (2)^2
C. (3x)^2 - (2)^2
D. None of the above
Answers
Answer:
C. (3x)^2 - (2)^2
Step-by-step explanation:
Each of the two terms is a perfect square, so the factorization is that of the difference of squares. Rewriting the expression to ...
(3x)^2 - (2)^2
highlights the squares being differenced.
__
We know the factoring of the difference of squares is ...
a^2 -b^2 = (a -b)(a +b)
so the above-suggested rewrite is useful for identifying 'a' and 'b'.

You are given two lines, the blue one and the one with the letters and are told to find the length of UV (which would just be from point U to point V)
The blue line seems to represent the total length of the black line and the length of VW is already shown. Since the total length is 16 and we alredy know that VW is 4, we'll subtract the two to find the length of UV
Which would be: 16-4=12
Answer:
Answer is 12.
Step-by-step explanation:
If UW is 16, and VW is 4, then just do 16-4 to get 12.

The area is the average of the the 2 numbers, that is
area of backyard = [tex]\frac{3.4+3.5}{2}[/tex] = [tex]\frac{6.9}{2}[/tex] = 3.45 acres
The area of the backyard will be 3.45 acres.
What is surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In other meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.
Given that area of backyards is halfway between 3.4 and 3.5 acres
It means an area of backyards will be an average of 3.4 and 3.5 acres
So,
Area of backyards = (3.4 + 3.5)/2 = 3.45 acre.
Hence "The area of the backyard will be 3.45 acres".
