Referring to the figure, the circle shown is drawn on grids. Find
A ÷ r and A ÷ r2.
a. 7.1, 3 c. 16, 4
b. 14.2, 3.2 d. 12, 2.7
Answers
Answer:
B. 14.2, 3.2
Step-by-step explanation:
diameter: 9 (count each box as 1)
d/2 = radius --> radius: 4.5
Area of a circle= πr^2
A= 63.6172
A/r = 63.6172/4.5 = 14.1
A/r^2= 63.6172/(4.5)^2 = 3.14

To find this answer you need to sort all of the numbers and find the 1st Quartile, and the 3rd Quartile.
0,0,0,1,2,2,4,5,7,8,10
The 1st and 3rd quartile in this set of numbers is 0 and 7.
To find inter range you subtract the 1st quartile from the 3rd. This would get you a answer of 7.

Answers
Answer:
Step-by-step explanation:
The (positive) slope of the line whose domain is (-infinity, -1) is
m = rise/run = 1/1, or m = 1. The (negative) slope of the other line segment is
m = rise/run = -1/1, or m = -1.
Let's now find the equation of the line with m = 1. Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2. Then the equation is y = x + 2 on the domain (-infinity, -1).
Now find the equation of the line with negative slope:
y = -x + b; the y-intercept is immediately evident from the graph as b = 0.
Then the desired eequation is y = -x on the domain (-1, infinity).

What is the answer to 33 < m - 91
Answers
Answer:
i think it should be:
m>124
Step-by-step explanation:
33<m-91
-m<-91-33
-m<-124
m>124
Answer:
The answer is m > 124.
Step-by-step explanation
Firstly, you have to move the terms 33 < m - 91
Second, you have to calculate like - m < - 124
Then, you have to change the signs like - m < - 124
So, this solves the solution as m > 124.
The music store bought a violin that cost v dollars. The store marked up the violin so it was 54% higher that what they bought it for. Which expression shows the cost of the violin?
A. v + 0.54v
B. 1 + 0.54v
C. v + 0.54
D. 0.54v
Answers
the expression is technically 54% of V. so to find the answer, we’d need to make 54% a decimal by dividing it by 100. once that’s done, we’ll be left with 0.54*v which is the same as 0.54v
A composite figure has a radius of 10 cm.
A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.
What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared
Answers
Answer:
C, 235.5 cm^2
Step-by-step explanation:
Formula for area of circle:
A = πr^2
Where π represents pi(3.14 or 22/7) and r represents the radius.
Plug in given value (10):
A = πr^2
A = 3.14(10)^2
A = 3.14(100)
A = 314
Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:
314/4
= 78.5
A quarter of this circle is 78.5, so let's subtract this from the total area (314):
314 - 78.5
= 235.5 cm^2
The area is 235.5 centimeters squared.

The highest number in Mr. Joe's class is 10 and the lowest is 5
\(10-5=5\\\) This is the range of Mr. Joe's class.
Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Find the equation of the axis of symmetry of the parabola. Each box in the grid represents 1 unit.
Answers
Answer:
The line x=b2a will serve as the parabola's axis of symmetry.
Detailed explanation:
Graph the parabola y=x2−7x+2 .
To get the values of a, b, and c, compare the equation with y=ax2+bx+c.
In this case, a=1, b=7, and c=2.
To write the axis of the symmetry equation, use the coefficient values.
The line x=b2a serves as the axis of symmetry for a quadratic equation of the form y=ax2+bx+c. Therefore, x=(7)2(1) or x=72 is the equation of the axis of symmetry of the given parabola.
To determine the vertex's y coordinate, change x=72 in the equation.
y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84 =−414
The vertex's coordinates are (72, 414) as a result.
Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.

While in France, Judy wants to sign up for a bike tour to see the countryside. She likes a tour that is 40 kilometers long, but she isn't sure how far that is. She decides to estimate the distance in miles. If Judy uses the fact that 1 kilometer is about 0.6 miles, what will her estimate be?
Answers
Answer:
The correct answer is 24 miles.
Step-by-step explanation:
Since 1 x 40 = 40, we must multiply 0.6 by 40.
0.6 x 40 = 24
Therefore, the tour is an estimate of 24 miles.
