Answer: Alexia, Benito and Carmen will paint 58.3%, 29.2% and 12.5% of the path, respectively.
Step-by-step explanation: Percentage is a ratio expressed as a fraction of 100, i.e., it represents a part from a total multiplied by 100.
In the way they decided to paint, they will have painted 120 m.
Alexia will paint 70 m. So the percentage is
[tex]\frac{70}{120}.100[/tex] = 58.3%
Benito will paint the next 15 m. The percentage is
[tex]\frac{15}{120}.100[/tex] = 12.5%
Carmen will paint the next 35 m. The percentage is
[tex]\frac{35}{120}.100[/tex] = 29.2%
Now, since it is a ratio, which means it is a proportion, percentage for all the path will be the same as the percentage of only a part of the path.
Then, the answer is Alexia will paint 58.3%, Benito, 12.5% and Carmen, 29.2% of the 5 km path.

What do the following two equations represent?
y - 2 = x + 20
y - 2 = -(x+20)
Answer: Perpendicular lines
Step-by-step explanation:
The first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.
The two equations, y - 2 = x + 20 and y - 2 = -(x + 20), represent linear equations in standard form. Let's break down each equation:
y - 2 = x + 20
This equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the value of x plus 20. This equation can be rearranged to slope-intercept form (y = mx + b) by isolating y:
y = x + 20 + 2
y = x + 22
The equation y = x + 22 represents a line with a slope of 1 and a y-intercept of 22.
y - 2 = -(x + 20)
Similarly, this equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the negative of the value of x plus 20. This equation can also be rearranged to slope-intercept form by isolating y:
y = -(x + 20) + 2
y = -x - 20 + 2
y = -x - 18
The equation y = -x - 18 represents a line with a slope of -1 and a y-intercept of -18.
In summary, the first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.

Step-by-step explanation:
f(x) + g(x) = 3x^2 + 2x - 1 + x^2 - 3x + 1
f(x) + g(x) = 4x^2 - x
==================================
f(x) - g(x) = 3x^2 + 2x - 1 - x^2 + 3x - 1

Given that x satisfies the inequality 20x > 33,
find the smallest value of x if x is a prime
number.
Answer:
2
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
20x > 33 = 2
Step-by-step explanation:
divide 20x by 20 do the same with 33
20x/20 > 33/20
x > 1.65
1 isnt a prime number and the closest prime number to 1.65 is 2
the answer is x > 2

k+a=500
3k+10a=3,600
find k and a using elimination plss helppp
Answer:
a=300 and k=200
Step-by-step explanation:
Multiply the first equation by -10,and multiply the second equation by 1.
−10(a+k=500)
1(10a+3k=3600)
Becomes:
−10a−10k=−5000
10a+3k=3600
Add these equations to eliminate a:
−7k=−1400
Then solve−7k=−1400for k:
−7k=−1400 (Divide both sides by -7)
[tex]\frac{-7k}{-7} =\frac{-1400}{-7}[/tex]
Now that we've found k let's plug it back in to solve for a.
Write down an original equation:
a+k=500
Substitute200forkina+k=500:
a+200=500
a+200+−200=500+−200(Add -200 to both sides)
a=300

Can a triangle with side lengths of 15, 13, and 6 can be classified as a right triangle? ? and why?
Answer:
The triangle cannot be classified as right angled triangle.
Step-by-step explanation:
Given measurements are;
15, 13 and 6.
In right angle triangle, the sum of square of lengths of smaller sides is equal to square length of larger side.
Therefore,
[tex](6)^2 + (13)^2 = (15)^2\\36 + 169 = 225\\205 \neq 225[/tex]
Hence,
The triangle cannot be classified as right angled triangle.
