Answers
Answer:
24% finished, 76% did not
Step-by-step explanation:
12cars/50 total +24%, and then just subtract 100% by the 24 to get 76% for the remaining percent
Answer:
24% finished and 76% did not
Step-by-step explanation:
you have the ratios:
12/50 and 38/50
These have to be turned into percentages so they need to have a denominator of 100
to do this, figure out what you have to multiply the denominator by to get 100
In this case, 50 times 2 is equivalent to 100.
Then, whatever you multiplied the denominator by, you multiply the numerator by
In this case, 12 times 2 is 24 and 38 times 2 is 76
Once you have the end products, take the numerator and add a percentage sign to it

Determine if the conclusion that follows from the given statements below is valid. If valid which law was used?
1. if a number is a natural number then it is a whole number
2. if a number is a whole number then it is an integer
Conclusion : if a number is a natural number then it is an integer
Answers
Answer:
the conclusion is not valid
Answer: The conclusion is valid by the law of syllogism
The law of syllogism follows the basic form:
If P, then Q
If Q, then R
Therefore, if P then R
We can write it like this
[tex]P \to Q \\\\Q \to R\\\\\therefore P \to R[/tex]
We can think of it like starting at town P, moving to Q, then to R. Or we could go from P directly to R if we aren't worried about the town in the middle (town Q).
Which lines are perpendicular to the line y – 1 = One-third(x+2)
Answers
Answer:
[tex]y-1=-3(x+2)[/tex]
Step-by-step explanation:
The equation of the given line:
[tex]y-1=\frac{1}{3}(x+2)[/tex]
This equation is in the form [tex]y-y_{1}=m(x-x_{1})[/tex]. Therefore, 1/3 is the slope.
To find a perpendicular line, take the opposite reciprocal of the slope (-1/old slope). Therefore, the slope of the perpendicular line is -3.
The equation of the perpendicular line: [tex]y-1=-3(x+2)[/tex]
(2x + 25) y

solve to get the answers of the variables
Answers
Answer:
y = 65 degrees
Step-by-step explanation:
(this is what i remember from geometry at least so let me know if i got anything wrong)
2x+25 and 3x-10 are opposites which means they are equal to each other.
2x+25 = 3x-20 get the x values on the same side by subtracting 2 from both sides
25 = x-20 to get the x value alone add 20 to both sides
45 = x
now you can plug in x to either equation to find out what their degree is
2(45)+25 = 115 degrees
and since this equation and y are on the same line you can subtract 115 from 180 (a line is equal to 180 degrees) to find y
180-115 = 65 degrees
Each of the pairs of opposite angles made by two intersecting lines is called a vertical angle. The value of the variables x and y are 35 and 85, respectively.
What are vertical angles?Each of the pairs of opposite angles made by two intersecting lines is called a vertical angle.
The angle measuring (2x+25)° and (3x-10)° are vertical angles. Therefore, we can write,
(2x + 25) = (3x - 10)
2x + 25 = 3x - 10
25 + 10 = 3x - 2x
x = 35
Also, in the given image the angle measuring (2x + 25)° and y° are supplementary angles, therefore, we can write,
(2x + 25)° + y° = 180°
2x + 25 + y = 180°
Substitute the value of x,
2(35) + 25 + y = 180
70 + 25 + y = 180
95 + y = 180
y = 85°
Hence, the value of the variables x and y are 35 and 85, respectively.
