Answer:
[tex]9x^{5}y^{5}[/tex] yards.
Step-by-step explanation:
Given that the area of a rectangle (A) is [tex]45x^{8}y^{9}[/tex] square yards.
If the length of the rectangle (L) is given to be [tex]5x^{3}y^{4}[/tex] yards, then we have to find the width (W) of the rectangle in yards.
Now, A = L × W
⇒ [tex]W = \frac{A}{L} = \frac{45x^{8}y^{9}}{5x^{3}y^{4}} = (\frac{45}{5})\times (\frac{x^{8}}{x^{3}}) \times (\frac{y^{9}}{y^{4}}) = 9x^{8 - 3}y^{9 - 4} = 9x^{5}y^{5}[/tex] yards. (Answer)
10(5g+2h-3)-4(3g-4h+2)
Step-by-step explanation:
[tex]10(5g+2h-3)-4(3g-4h+2) \\ \\ = 50g + 20h - 30 - 12g + 16h - 8 \\ \\ = 50g - 12g + 20h + 16h - 30 - 8 \\ \\ = 38g + 36h - 38[/tex]
Answer:
38(g - 1) + 36h
Step-by-step explanation:
10(5g + 2h - 3) - 4(3g - 4h + 2)
= 50g + 20h - 30 - 12g + 16h - 8
= 38g + 36h - 38
= 38(g - 1) + 36h

The students at Gregori were having a vote to decide on a new color. 5/8 of the students voted for blue. 5/9
of the remaining students voted for green. 48 students voted for red. How many students voted for blue and
green?
180 students voted for blue and 60 students voted for green
Solution:
Let "x" be the total number of votes
From given,
[tex]\frac{5}{8}[/tex] of the votes were for blue
[tex]Blue\ votes = \frac{5}{8}x[/tex]
Therefore,
[tex]Remaining = 1 - \frac{5}{8}x = \frac{8x-5x}{8} = \frac{3x}{8}[/tex]
Given that,
5/9 of the remaining students voted for green
So we get,
[tex]Green\ votes = \frac{3x}{8} \times \frac{5}{9} = \frac{5x}{24}[/tex]
[tex]Green\ votes = \frac{5x}{24}[/tex]
So we have now accounted for 5/8 (blue) + 5/24 (green) of the votes
Therefore,
[tex]Remaining = 1-(\frac{5x}{8} + \frac{5x}{24}) = 1 -(\frac{15x+5x}{24})= 1 -\frac{20x}{24} = \frac{24x-20x}{24}\\\\Remaining = \frac{4x}{24}\\\\Remaining = \frac{1x}{6}[/tex]
48 students voted for red
Therefore, remaining 1/6 votes for 48
Let "x" be the total number of votes
Then we can say,
1/6 of "x" is equal to 48
[tex]\frac{1}{6} \times x = 48\\\\x = 48 \times 6\\\\x = 288[/tex]
Number of votes for Blue:
[tex]Blue\ votes = \frac{5}{8} \times x = \frac{5}{8} \times 288\\\\Blue\ votes = 180[/tex]
Number of Green votes:
[tex]Green\ votes = \frac{5}{24} \times x = \frac{5}{24} \times 288\\\\Green\ votes = 60[/tex]
Thus 180 students voted for blue and 60 students voted for green

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.

write the inverse of the statement below. if you are over 18 then you can vote
Answer:
whats the statement
Step-by-step explanation:
Final answer:
The inverse statement is 'If you cannot vote, then you are not over 18,' but practical exceptions exist. The 26th Amendment ensures those over 18 have the right to vote, illustrating the importance of voting as a democratic right. Encouraging voter registration and participation among eligible citizens is crucial for maintaining a vibrant democracy.
Explanation:
The inverse of the statement 'If you are over 18 then you can vote' would logically be 'If you cannot vote, then you are not over 18'. However, this inversion doesn't always hold true in practice due to various voting laws and conditions, such as registration requirements and citizenship. The right to vote is a fundamental aspect of democracy, emphasized by constitutional amendments and various voting rights acts that seek to protect this privilege. For instance, the 26th Amendment to the U.S. Constitution, ratified on March 23, 1971, prohibits the denial of the right to vote for U.S. citizens eighteen years of age or older based on age.
To encourage political participation, it is vital for eligible citizens to register to vote and exercise their right. This act of voting allows individuals to have a say in how their government is run and who represents their interests. Discussions about lowering the voting age further, to include 16 and 17-year-olds, in local, state, or national elections have sparked debates about civic engagement and the readiness of younger citizens to participate in the electoral process.

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.

Which values of p are solutions to the inequality shown? Check all that apply.
|18 – 2p| > 8
–10
–5
0
5
10
15
To find the values of p that satisfy |18 - 2p| > 8, we solve two separate inequalities, leading to the solutions p < 5 and p > 13. Hence, among the options provided, -10, -5, and 15 are the correct solutions.
Explanation:To solve the inequality |18 – 2p| > 8, we need to consider two cases because the absolute value measures distance from zero on a number line, either in the positive or negative direction.
Case 1: 18 - 2p > 8First, we solve the inequality when the expression inside the absolute value is positive:
18 - 2p > 8-2p > -10p < 5Case 2: 18 - 2p < -8Next, we solve the inequality when the expression inside the absolute value is negative:
18 - 2p < -8-2p < -26p > 13Combining the solutions from both cases, the values of p that satisfy the original inequality are p < 5 and p > 13. Among the given options, -10, -5, and 15 are the values that are solutions to the inequality.
Final answer:
The values of p that satisfy the inequality |18 - 2p| > 8 are p < 5 and p > 13; therefore, from the given options, -10 and -5 are the correct solutions.
Explanation:
The student needs to determine which values of p satisfy the inequality |18 – 2p| > 8. To solve this, we consider two separate cases because the absolute value function defines a piecewise function. The two cases are when the expression inside the absolute value is positive and when it is negative.
For the first case (18 - 2p > 0), we solve 18 - 2p > 8, which simplifies to -2p > -10, and upon dividing by -2 and flipping the inequality sign, we get p < 5. For the second case (18 - 2p < 0), we solve -(18 - 2p) > 8, which simplifies to -18 + 2p > 8, leading to 2p > 26, and upon dividing by 2, we get p > 13.
Therefore, the solution to the original inequality consists of all the values p < 5 and p > 13. Checking the provided options against these conditions, only -10 and -5 fall within p < 5, so they are the solutions to the inequality.

Height of the can (h) = 5 in
Radius of the can (r) = 6 in
The can is in the shape of a cylinder.
Surface area of the cylinder = [tex]2 \pi r^{2}+2 \pi r h[/tex]
Surface area of the can = [tex]2 \times3.14 \times 6^{2}+2 \times 3.14 \times 6\times 5[/tex]
[tex]$=226.08+ 188.57[/tex]
[tex]=414.65[/tex]
Surface area of the can = 414. 65 in²
Area of sheet of metal = 3750 in²
To find how many cans able to make:
[tex]$\text { Number of cans} =\frac{\text { Area of sheet metal }}{\text { Surface area of the can }}[/tex]

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 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
