The circumference of the circle is 26π, having center at point (3,-7) and a point on the circle is (8,5).
What is circle?
A circle is a round-shaped picture, that has no corners or edges, in geometrical figure it has the largest area for any given length or parameter.
The point of center of the circle 0 = (3, -7).
And the point on the circle C = (8, 5).
The radius of the circle = the distance between center and point on circle
Use the formula to find distance between two points,
The distance between two points A(x₁, y₁) and B(x₂, y₂)
Distance
= √(x₂ - x₁)² + (y₂ - y₁)²
= √(8-3)² + (5 + 7)₂
= √5² + 12²
= √25 + 144
= √169
= 13
The radius of the circle r = 13.
The circumference of the circle = 2πr = 2 x π x 13 = 26π.
The circumference of the circle is 26π.

PLS HELP I NEED THIS SHSAT MATH QUESTION!!!
On Friday, Marvin sold 4 suits that had a mean sale
price of $125. On Saturday, he sold 6 suits that had
a mean sale price of $140. What was the mean sale
price, to the nearest dollar, for all 10 of the suits he
sold on Friday and Saturday?
A. $130
B. $132
C. $133
D. $134
Answer:
C.$133
Step-by-step explanation:
You have to add all numbers then divide by how many numbers there are.
So, in this case, you must add 125 and 140 to get 265
Then you must divide by 2 since there are 2 numbers
265/2 = 132.5
Round to the nearest dollar
The final answer is $133
(08.01) The graph shows two lines, Q and S.
A coordinate plane is shown with two lines graphed. Line Q has a slope of one half and crosses the y axis at 3. Line S has a slope of one half and crosses the y axis at negative 2.
How many solutions are there for the pair of equations for lines Q and S? Explain your answer.
[tex]\huge\blue{ANSWER}:—[/tex]
A solution for a pair of lines means that they are equal to each other. This occurs when they instersect. Since the lines have the same slope, but are not the same line, they are parallel, so they will never intersect. This means there are zero solutions.
Hope this helps!The provided set of equations for the lines Q and S have no solutions.
What is the Slope of a line?The slope of a line is a measure of how steep the line is and is defined as the change in y divided by the change in x between any two points on the line. In other words, the slope is the ratio of the vertical distance between two points on the line to the horizontal distance between them.
What are parallel lines?Parallel lines are two or more straight lines that are equidistant from each other at all points and do not intersect, no matter how far they are extended in both directions. Parallel lines are often denoted by a double vertical line symbol (||) drawn between them.
In the given information:
Line Q crosses the y-axis at 3 and has a slope of one-half.
Therefore,
x=0 and y= 3
Straight line equation: y= mx + c
where m is the line's slope
The values in this equation should be replaced.
y= mx + c
3= (1/2) ×0+c
3 = c
y= (1/2) x + c
Line S crosses the y axis at -2 and has a slope of one half.
Thus, the c will be negative.
After that, the line's equation is y = (1/2) x - 2.
Use the equation to plot the graph.
So,
Line Q and Line S are parallel lines.
Due to the fact that it won't intersect, there is an equation.
Thus, the provided pair of equations for lines Q and S have no solutions.

Tara created the poster shown below:
A rectangle is shown. The length of the rectangle is labeled as length equal to 24 cm, and the width is labeled as width equal to 36 cm.
What would be the dimensions of the poster at fraction 1 over 4 times its current size?
Length = 96 cm, width = 144 cm
Length = 6 cm, width = 9 cm
Length = 20 cm, width = 32 cm
Length = 28 cm, width = 40 cm
Answer:
B

1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)

4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 864 < 1512
2. 12 > 0
3. question 3 is wrong -2 = -2
4. -0.5 < 1
5. In the above operations, they did not effect the inequality sign because the same operation is being done to both sides, therefore the inequality sentences all remained true.
Step-by-step explanation:
1. (3)(4) < (7)(3)
(2)12 < 21(2)
(4)24 < 42(4)
(9)96 < 168(9)
= 864 < 1512
2. 3+11 > -2+3
3+ 13 > 1 + 3
-4+16 > 4-4
= 12 > 0
3. -2 = -2 (question 3 is wrong)
4. -4/-4 < 8/-4
1/-2 > -2/-2

11 = 1 + 3r + 2r
I really need help with this!!
Answer:
r = 2
Step-by-step explanation:
I'm assuming we're finding r
11 = 1 + 3r + 2r
Add up the numbers with r
11 = 1 + 5r
Subtract both sides by 1
11 = 1 + 5r
-1 -1
10 = 5r
Divide both sides by the coefficient, 5, to isolate the variable, r
10/5 = 5r/5
r = 2
Step-by-step explanation:
11=1+5r
11-1=5r
5r=10
r=10/5
r=2
