If x is a rational number and y is a rational number than x + y is a rational number.
A)
Always True
B
Sometimes True
C)
Usually True
D)
Never True
Answer:
A)
Step-by-step explanation:
The set of rational numbers is closed for all the four operations‚ so x+y‚ x-y‚ x*y and x/y are rational too a rational number can be expressed as a fraction of two integers. so‚ x can be expressed as a/b and y as c/d.
Write
77
as a decimal
40?
1.925
Explaining:to write 77/40 as a decimal you have to divide the numerator by the denominator of the fraction.We divide now 77 by 40 what we write down as 77/40 and we get 1.925

Answer:
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.

if the area of a backyard is exactly halfway between 3.4 and 3.5 acres what is the area of the backyard
Answer:
3.45 acres
Step-by-step explanation:
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".

Step-by-step explanation:
(x^3 - 9x) divided by (x^3 + x^2 - 6x)
= x(x^2 - 9) divided by x(x^2 + x - 6)
= x(x + 3)(x - 3) divided by x(x - 2)(x + 3)

One person can complete a typing project in 6 hours, and another can complete the same project in 9 hours. How long will it take the two people working together to complete the project?
Answer:
3.6 hours
Step-by-step explanation:
One person can complete a typing project in 6 hours,
Hence, in 1 hour, 1/6 of the project is completed by person A
Another can complete the same project in 9 hours.
Hence, in 1 hour, 1/9 of the project is completed by person B
Let the number of hours of completing the project be represented by 1
Hence,
x/6 + x/9 = 1
We find the L.C.M
9x + 6x/54= 1
15x/54 = 1
Cross Multiply
15x = 54
x = 54/15
x = 3.6 hours.
Therefore, both people can complete the project in 3.6 hours.
if a fraction converts into a decimal that eventually stops what do you call it ??
Answer:
Terminating decimal.
Step-by-step explanation:
We need to find, if a fraction converts into a decimal that eventually stops what do we call it.
If a fraction converts into a decimal that eventually stops is called terminating decimals.
For example : 0.1, 2.45, 3.4657 etc.
If a fraction converts into a decimal that is repeating and do not stops is called non-terminating recurring decimals.
For example : 0.333..., 2.3454545... etc.
If a fraction converts into a decimal that is not repeating and do not stops is called non-terminating, non-recurring decimals.
For example : 0.2345172..., 2.34093795... etc.
Therefore, required answer is terminating decimal.

Answer:
12
Step-by-step explanation:
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.

To factor 9x^2 - 4, you can first rewrite the expression as:
A. (3x-2)^2
B. (x)^2 - (2)^2
C. (3x)^2 - (2)^2
D. None of the above
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'.

Step-by-step explanation:
180 - 116 = 64
supplementary angles are when 2 degrees add up to 180
so if one of them is 116 then you subtract that from 180 and get 64
so the other angle would be 64 degrees
Answer:
64 degrees

Eduardo solved the following inequality, and his work is shown below: −5(x + 4) + 21 ≥ −3 + 4(x − 8) −5x − 20 + 21 ≥ −3 + 4x − 32 −5x + 1 ≥ 4x − 35 −9x ≥ −36 x ≥ 4 What mistake did Eduardo make in solving the inequality? (2 points)
Answer:
the comparison was not reversed when dividing by -9
Step-by-step explanation:
It looks like Eduardo's steps might be ...
−5(x + 4) + 21 ≥ −3 + 4(x − 8)
−5x − 20 + 21 ≥ −3 + 4x − 32 . . . . correct
−5x + 1 ≥ 4x − 35 . . . . correct
−9x ≥ −36 . . . . correct
x ≥ 4 . . . . . should be x ≤ 4
Dividing by -9 should reverse the comparison symbol.

area of B = area of A × (5.2)² = 8 × (5.2)² = 216.32 cm²
Find the solution set for this inequality, -2x + 4 > -4x + 8
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]

Solve for s.
0.5s +1= 7+ 4.58
S =?
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
