Whose statement makes sense? Whose statement is nonsense? Carla said The shaded angle represents 1/4 of the circle, Adam states the shaded angle represents 3/8 of the circle
Step-by-step explanation:
The attached figure shows a circle. In this circle, some of the part is shaded with a color.
In the figure, we have drawn lines from red color. It shows that there is 1 part shaded out of 4 parts.
Carla said The shaded angle represents 1/4 of the circle while Adam states the shaded angle represents 3/8 of the circle.
The fraction for the shaded part is 1/4. Hence, Carla is correct.

15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from Con<br />AB is 4.5 cm find its area.
Answer: The area of the parallelogram ABCD = 32.4 sq. cm
Step-by-step explanation:
Given: In parallelogram ABCD, AB = 7.2 cm and the perpendicular drawn from C (altitude) on AB is 4.5 cm i.e.e height =4.5 cm.
Area of parallelogram = [tex](Base \times height)[/tex]
Then, Area of parallelogram ABCD = [tex]7.2\times4.5[/tex]

determine whether x=33 is a solution of the equation below 3= x/11
Answer:
Yes, x = 33 is a solution
Step-by-step explanation:
To see if it is a solution, plug in 33 as x
3 = x/11
3 = 33/11
3 = 3
Since this is correct, x = 33 is a solution.
Given,
The value of x is 33.
[tex] \implies \: 3 = \bf\dfrac{x}{11} [/tex]
[tex] \implies \: 3 \times 11 = \bf x[/tex]
Putting the value of x ..
[tex] \implies \: 33 = 33[/tex]
Left hand side is equal to right hand side, it means that x = 33 is a solution of given equation.

Step-by-step explanation:
At Mario’s Italian restaurant, 118 of the 200 plates are dirty. What percent of the plates are clean
Answer:
41%
Step-by-step explanation:
First, we have to find what percent is dirty, so our equation is:
118/200 = 59/100 = 59%
Then we have to find how much of 100% is left after we take away 59%:
100 - 59 = 41
So 41% of the plates are clean
Linear equation: 5(3x+9) -2x = 15x - 2 (x-5)
Answer:
There are no solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
5(3x+9)−2x=15x−2(x−5)
Step 1: Simplify both sides of the equation.
5(3x+9)−2x=15x−2(x−5)
(5)(3x)+(5)(9)+−2x=15x+(−2)(x)+(−2)(−5)(Distribute)
15x+45+−2x=15x+−2x+10
(15x+−2x)+(45)=(15x+−2x)+(10)(Combine Like Terms)
13x+45=13x+10
13x+45=13x+10
Step 2: Subtract 13x from both sides.
13x+45−13x=13x+10−13x
45=10
Step 3: Subtract 45 from both sides.
45−45=10−45
0=−35

Definition of isosceles triangle.
Answer:
I think the answer would be A) If two angles are equal in a triangle, then the sides opposite are equal.
Step-by-step explanation:
I hope this helps, have a nice day :]
AB = BC
AC is the opposite side of ∠2.
BC is the opposite side of ∠1.
Opposite sides of equal angles are equal.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
∠3 = ∠1
From the figure, we see that,
∠3 and ∠2 are vertical angles.
Vertical angles are equal.
Now,
∠2 = ∠1
AC is the side opposite to ∠2.
BC is the side opposite to ∠1.
The sides that are opposite to equal angles are also equal.
Thus,
AC and BC are equal.

What is the slope of this ?
Answer:
Essentially, slope is rise/run. Rise is how many units up the graph, and run is how far to the left or right it goes. Rise will be negative if it's going down, and run will be negative if it's going left. There's two ways to find the slope in this case.
1. Stick to the more visual aspect of it, and count how many units up from one point to the next point. Point (1,2) is 2 units up from point (0,0). Then you count how many units right or left it goes. In this case, it's 1 towards the right. This means the rise/run comes out to be 2/1, which means the slope=2.
2. Look at the equations. y=mx+b is the linear format for these lines. y is the y coordinate, m is the slope, x is the x coordinate, and b is the y intercept (the point where x=0). These two lines have shared slope values, which means the slope for both of them is 2.

which equation describes a line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3?
Answer:
The equation of the line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:
[tex]y=-\frac{5}{2}x+13[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the line
y=2/5x+3
comparing with the slope-intercept form of the line equation
Thus, the slope of the line is: m = 2/5
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 2/5
Thus, the slope of the the new perpendicular line = – 1/m = [-1]/[2/5] = -5/2
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the slope of perpendicular line m = -5/2 and the point (4, 3)
[tex]y-3=-\frac{5}{2}\left(x-4\right)[/tex]
Add 3 to both sides
[tex]y-3+3=-\frac{5}{2}\left(x-4\right)+3[/tex]
[tex]y=-\frac{5}{2}x+13[/tex]
Therefore, the equation of the line that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:
[tex]y=-\frac{5}{2}x+13[/tex]
