The paper would be 112589991 km thick if folded 50 times.
Step-by-step explanation:
Step 1; The sheet is [tex]\frac{1}{10}[/tex]mm thick which equals 0.1 mm. Every time it is folded it doubles in thickness. So if folded once it becomes 0.2 mm thick, if folded thrice it becomes 0.4mm thick.
Thickness if folded once = [tex]2^{1}[/tex] × 0.1 mm
thickness if folded twice = [tex]2^{2}[/tex]× 0.1 mm
Thickness if folded thrice = [tex]2^{3}[/tex] × 0.1 mm.
So if the paper is folded nth fold it would be [tex]2^{n}[/tex] × 0.1 mm thick.
Step 2; Using the above formula, if the paper is folded 50 times the thickness would be equal to [tex]2^{50}[/tex] × 0.1 mm = 112,589,990,684,262.4 mm.
1 km is equivalent to [tex]10^{6}[/tex]mm so 112,589,990,684,262.4 mm = 112,589,990.6842624 km which is rounded off to 112589991 km.

Answer:
Step-by-step explanation:
Advertising a music festival, Paul saw a billboard while he was driving on the highway.
What is the best way, if any, to rewrite this sentence?
A.
While he was driving on the highway advertising a music festival, Paul saw a billboard.
B.
Advertising a music festival, Paul saw a billboard driving on the highway.
C.
no change
D.
While he was driving on the highway, Paul saw a billboard advertising a music festival.
The best way to rewrite the sentence is option D: "While he was driving on the highway, Paul saw a billboard advertising a music festival."
The original sentence is a bit awkward in its structure. Let's evaluate the options:
A. "While he was driving on the highway advertising a music festival, Paul saw a billboard."This option is incorrect because it suggests that Paul was the one advertising the music festival while driving, which is not the intended meaning.
B. "Advertising a music festival, Paul saw a billboard driving on the highway."This option is incorrect because it implies that the billboard itself was driving on the highway, which is illogical.
C. "No change"This option maintains the original structure of the sentence, which is awkward and does not convey the intended meaning clearly.
D. "While he was driving on the highway, Paul saw a billboard advertising a music festival."This option correctly places the modifier "advertising a music festival" next to "billboard," clarifying that it was the billboard, not Paul, advertising the music festival.

Which could be the other dimension of the second photograph?
Answer:
15 inches
Step-by-step explanation:
Since the rectangles are similar then the ratios of corresponding sides are equal.
let x be the other dimension in the second photograph, then
[tex]\frac{4}{10}[/tex] = [tex]\frac{6}{x}[/tex] ( cross- multiply )
4x = 60 ( divide both sides by 4 )
x = 15
Thus the other dimension in the second photograph is 15 inches.
Which system of equations below has exactly one solution?
y=-8x - 6 and y = –8x + 6
y=-8x - 6 and 1/2y = -4x - 3
y=-8x - 6 and y = 8x - 6
y = -8x - 6 and -y = 8x + 6
Answer:
(y = -8x - 6 and y = 8x - 6) will have exactly one solution.
Step-by-step explanation:
1) Check number of solutions for A (using substitution)
y = -8x -6
y = -8x + 6
-8x - 6 = -8x + 6
+8x +8x
0 - 6 = 0 + 6
-6 = 6 (since this is false, it would be no solution)
2) Check number of sultions for B (using substition)
y = -8x - 6
1/2y = -4x -3
y = -8x - 6 (Multiply both sides of second equation by 2 to cancel out fraction on left side)
-8x - 6 = -8x - 6
Since this is the same equation on both sides- when you cancel everything out it will be 0=0, meaning infinite solution
3) Check number of solutions for C (using substition)
y = -8x - 6
y = 8x - 6
-8x - 6 = 8x - 6
+8x +6 = +8x +6
0 = 16x
x=0
The X value for the solution is 0, when we plug in this X value into one of the equations and solve for Y we will be able to get the Y coordinate
y = -8(0) - 6
y = -6
The solution for C will by (0,-6) which is one solution.
4) Check number of solutions for D (using substition)
y = -8x - 6
-y = 8x +6 --> y = -8x -6
muiltiply both sides of second equation by -1 to make the y positive
-8x - 6 = -8x - 6
Since this is the same equation on both sides- when you cancel everything out it will be 0=0, meaning infinite solution
Which mathematical statement is correct?
Answer:
B is the correct option.
Step-by-step explanation:
Place the values from the given options in equations of f(n) and g(n).
Write the answer of each of the following.
For instance, option A gives:
f(6)= 31
g(6) = 24
Option B gives:
f(7)= 63
g(10)= 36
Option C gives:
f(5)= 15
g(8)=30
Option D gives:
f(5)=15
g(5)=21
Thus option B is correct because f(7) is greater than g(10).
Answer:
B. f(7) > g(10)
Step-by-step explanation:
f(7) = 2⁶ - 1 = 63
g(10) = 3×10 + 6 =36
since 63>36 then f(7) > g(10)

you can buy popcorn at the village theater in small, medium, or large sizes. the pop corn can be buttered or plain. if all the choices are equally likely, what is the probability that a customer chooses a medium size with butter
Answer:
Step-by-step explanation:
Close to none because they are all the same price
The probability of a customer choosing a medium size popcorn with butter is 1/6, or about 16.67%.
To find the probability that a customer chooses a medium size popcorn with butter from the Village Theater, we need to consider the total number of possible outcomes and the number of favorable outcomes. Given there are small, medium, and large sizes, and each can be buttered or plain, there are 3 sizes imes 2 types (buttered or plain), which results in 6 total possible outcomes. The event of choosing a medium size with butter is just one of these possible configurations.
Probability of choosing a medium size with butter = Number of favorable outcomes / Total number of possible outcomes = 1 / 6
The chance is 16.67%, which is the decimal 1/6 expressed as a percentage.

In the diagram below line FG is // to line HI, and line segments BC and AD intersect a E. The measure of angle GBE=3x+20, and measure angle ECD=x.
Answer:
x = 40
Step-by-step explanation:
Since FG and HI are parallel and BC is a transversal, then
∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus
3x + 20 + x = 180, that is
4x + 20 = 180 ( subtract 20 from both sides )
4x = 160 ( divide both sides by 4 )
x = 40

Which expression is equivalent to 9a1/2b14c3/2?
The given algebraic expression 9a1/2b14c3/2 appears to be a kind of factorization where a, b, c are variables raised to different powers. Unless values for these variables are provided, this expression can't be simplified further.
Explanation:The expression 9a1/2b14c3/2 is considered as a form of factorization in mathematics where a, b, c denote variables, and the numbers 1/2, 14, 3/2 are their respective exponents. In other words, it's a product of the variables 'a', 'b', and 'c' raised to their respective powers. For instance, 'a' is under a square root (as signified by the power of 1/2), 'b' is raised to the power of 14, and 'c' is also under a square root but cubed (a power of 3/2).
Consequently, this expression doesn't seem to have a simpler or equivalent expression because the terms 'a', 'b', and 'c' are likely representing different entities, hence they can't be combined or simplified further. However, should there be values for 'a', 'b', and 'c', it's simply substituted into the expression and calculated accordingly.
