The measure of the angle is;
200.64 degrees ⇒ B
200 degrees 38' 24" ⇒ C
Step-by-step explanation:
To convert the measure of an angle from degrees to radians or from radians to degrees use these rules
If the measure of the angle is x°, then multiply it by [tex]\frac{\pi }{180}[/tex] to find its measure in radiansIf the measure of the angle is x radians, then multiply it by [tex]\frac{180}{\pi }[/tex] to find its measure in degrees∵ The measure of an angle is 3.5 radians
- We need to change its measure to degree, use the 2nd rule
∵ π = 3.14
∴ Its measure in degree = [tex](3.5).(\frac{180}{3.14})[/tex]
∴ Its measure in degree = 200.64°
To find its measure in degree, minutes and seconds, multiply the number before decimal point by 60 to find the number of minutes
∵ 1° = 60'
∵ 0.64 × 60 = 38.4
- That means the number of minutes is 38
∵ 1' = 60"
∵ 0.4 × 60 = 24
- That means the number of seconds is 24
∴ The measure of the angle is 200° 38' 24"
The measure of the angle is;
200.64 degrees
200 degrees 38' 24"

According toThe Humane Society in 2009 33% of US households owned at least one cat and 56% of households who did own cats owned at least 2. the US Census Bureau tells us that there were 116 million households in 2009 how many households owned at least two cats report your answer in millions around the two places
Answer:
21.4368 ≅ 21.44 million households owned at least two cats.Step-by-step explanation:
Total number of households were 116 million.
Hence, 100% = 116 million.
33% of the total US households owned at least one cat.
Hence, the number of household having at least one cat is [tex]\frac{33\times116}{100} = \frac{3828}{100} = 38.28[/tex] million.
It is also given that 56% of that 38.28 million households owned at least 2 cats.
Hence, the number of households having 2 cats is [tex]\frac{56\times38.28}{100} = \frac{2143.68}{100} = 21.4368[/tex] million.
To find the number of households that owned at least two cats in 2009, we need to calculate 56% of the total number of households that owned cats. We can use the information provided by The Humane Society and the US Census Bureau to calculate this number.
Explanation:To find the number of households that owned at least two cats in 2009, we need to calculate 56% of the total number of households that owned cats. First, we find the number of households that owned at least one cat by calculating 33% of the total number of households. Then, we multiply this number by 56% to find the percentage of households that owned at least two cats. Finally, we multiply this percentage by the total number of households to get the final answer.

what is the slope of y=-1/3x+4the slope of y=-1/3x+4
Answer:
-1/3
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
What is the slope of the line represented by the equation ? 3x + 4y = 8
Answer:
-3/4
Step-by-step explanation:
3x + 4y = 8....find the slope
in y = mx + b form, the slope can be found in the m position...so lets put this equation in y = mx + b form
3x + 4y = 8.....subtract 3x from both sides
4y = 8 - 3x.....now divide both sides by 4
y = 2 - 3/4x....rearrange
y = -3/4x + 2
y = mx + b
y = -3/4x + 2
as u can see, the number in the m position (the slope) = -3/4
The slope of the line represented by the equation 3x + 4y = 8 is -3/4.
Explanation:The slope of a line can be determined from its equation in slope-intercept form, which is of the form y = mx + b. The coefficient of x, m, represents the slope of the line. In the given equation 3x + 4y = 8, we can rearrange it to the slope-intercept form by isolating y: 4y = -3x + 8, y = (-3/4)x + 2. Therefore, the slope of the line represented by this equation is -3/4.

Write y=1/6x+5 in standard form using integers Please
The standard form of the line is [tex]6y-x=30[/tex]
Step-by-step explanation:
The equation of the line in this problem, written in the point-slope form, is
[tex]y=\frac{1}{6}x+5[/tex] (1)
We want to rewrite it in the standard form with integers, that means in the form
[tex]ax+by=c[/tex]

Given:
Let,
point A( x₁ , y₁) ≡ ( 3 ,-6)
point B( x₂ , y₂ )≡ (-1 , 2)
To Find:
Equation of Line AB =? ( Assumption)
Solution:
Equation of a line passing through a points A( x₁ , y₁) and point B( x₂ , y₂ ) is given by the formula Two -Point Form,
[tex](y-y_{1})=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }\times (x-x_{1})[/tex]
Now on substituting the slope and point A( x₁ , y₁) ≡ ( 3 , 6) and B( x₂ , y₂ )≡ (-1 , 2) we get
[tex](y-(-6))=\dfrac{2--6}{-1-3}\times (x-3)\\\\y+6=\dfrac{8}{-4}(x-3)\\\\y+6=-2(x-3)\\y+6=-2x+6\\y=-2x[/tex] .....Required Equation of line

[tex]y=mx[/tex] ....Also called as Equation of line Passing through Origin.
where , m =slope
Therefore, Equation of line and the slope is
[tex]y=-2x[/tex]
[tex]Slope = -2[/tex]
To find the equation of a line passing through two given points, calculate the slope using the slope formula, and then substitute the slope and one of the points into the point-slope form of a line equation. The line passing through the points (3,-6) and (-1,2) is given by the equation y = -2x + 6.
Explanation:To find the equation of the line that passes through the points (3, -6) and (-1, 2), we use the formula for the slope, denoted as 'm': m = (y2 - y1) / (x2 - x1).
Then, we substitute the given pair of points into this formula to find the slope: m = (2 - -6) / (-1 - 3) = 8 / -4 = -2.
After obtaining the slope, we use the point-slope form of an equation of a line, which is y - y1 = m(x - x1). Substitute one of the given points (3, -6) and the slope -2 in: y - -6 = -2(x - 3).
Simplify this to get the final equation: y = -2x + 6.

Explain how you can determine whether this system has 0, 1, or infinitely many solutions without graphing. What does this reveal about the relationship between the lines on the graph?
Write at least 150–300 words please
Answer:
Step-by-step explanation:
0 solution example
3x+2y=2
3x+2y=4
This is a zero solution example, because you can see that both equations are the same on the left, yet different on the right.
Infinite solution example
3x+2y=2
4y=4-6x
This is an infinite solution example because if you look at both equations, you can see that they are exactly the same.
One solution example
2x+3y=15
x-3y=3
This is an one solution example because if you add the equations you get 3x=18 x=6
plug it in, and you get that x=6, y=1
If a system a infinite solutions, that means that the lines overlap
If a system has no solutions, that means that the lines never touch, or that they are parallel
If a system has one solution, it means that the lines intersect at one point.
A system of two linear equations in two variables can have 0, 1, or infinitely many solutions. The number of solutions can be determined without graphing by comparing the slopes and y-intercepts of the equations. If the slopes are equal and y-intercepts are different, the system has no solution. If the slopes are equal and y-intercepts are equal, the system has infinitely many solutions. If the slopes are not equal, the system has exactly one solution.
Explanation:One example of a system of two linear equations in two variables with 0, 1, or infinitely many solutions is:
Equation 1: 2x + 3y = 8
Equation 2: 4x + 6y = 16
To determine the number of solutions in this system without graphing, we can use the concept of slopes. If the slopes of the two lines are equal and the y-intercepts are also equal, then the system has infinitely many solutions. If the slopes are equal but the y-intercepts are different, then the system has no solution. If the slopes are not equal, then the system has exactly one solution.
In this example, both equations have the same slope of ½; however, the y-intercepts are different. Therefore, this system has no solution.
This reveals that the two lines in the graph of this system are parallel and will never intersect.
