9.Jessa drew a circle with a circumference of 18.84 inches. Which of these dimensions could be the diameter, in inches Jessa used to draw her circle? Use 3.14 for pi.
A 6
B 15.7
C 3
D 9.42
Answer:
A. 6
Step-by-step explanation:
Write the formula c = 2πr. Substitute the value 18.84 feet for c. Solve the equation for c. Since the radius always measures one-half the length of the diameter, multiply the value of c by 2.

A machine factory produces 2 parts per second. One shift is 10 hours long. What is the production rate in parts per shift?
60 seconds per minute
2 x 60 = 120 parts per minute
60 minutes per hour
120*60 = 7200 parts per hour
7200 x 10 hours = 72,000 parts per 10 hour shift

Write your answer as a fraction in simplest form.
A gift box is a rectangular prism14inches long,5inches wide,and 4inches high.If the box is to be covered in fabric ,how much fabric is needed if there is no overlap?
The total fabric needed would be 292 square inches.
To calculate how much fabric is needed to cover the gift box without overlap, we must find the surface area of the rectangular prism representing the box. The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l represents the length, w represents the width, and h represents the height.
Given the dimensions of the box are 14 inches (length), 5 inches (width), and 4 inches (height), we calculate the surface area as follows:
2 (14 × 5) = 2 × 70 = 140 square inches (for the top and bottom)2 (14 × 4) = 2 × 56 = 112 square inches (for the front and back)2 (5 × 4) = 2 × 20 = 40 square inches (for the left and right sides)The total surface area is 140 + 112 + 40 = 292 square inches of fabric needed to cover the entire box.

Solve x3 = 1 over 8.
Answer:
The simplified form of the provided equation is 1/2.
Step-by-step explanation:
Consider the provided equation.
[tex]x^3=\frac{1}{8}[/tex]
8 can be written as 2³
1 can be written as 1³
Therefore the provided equation can be written as:
[tex]x^3=\frac{1^3}{2^3}[/tex]
[tex]x^3=(\frac{1}{2})^3[/tex]
[tex]x=\frac{1}{2}[/tex]
Hence, the simplified form of the provided equation is 1/2.
Which undefined term is needed to define a circle
Answer:
the first one is "point" and the second is "1/2"
Step-by-step explanation:
The solution to the system of equation below is (−2, −1).
2x − 3y = −1
11x − 9y = −13
When the first equation is multiplied by −3, the sum of the two equations is equivalent to 5x = −10.
Which system of equations will also have a solution of (−2, −1)?
5x = −10
11x − 9y = −13
2x + 9y = −1
11x − 9y = −13
−6x + 9y = −1
11x − 9y = −13
−6x + 3y = −1
5x = −10
Answer:
The correct option is 1.
Step-by-step explanation:
If a system of equation have solution (a,b), then the equations of system must be satisfied by the point (a,b).
It is given that the system of have solution (-2,-1), so the equations of system must be satisfied by the point (-2,-1).
The system of equation in option 1 is
[tex]5x=-10[/tex]
[tex]11x-9y=-13[/tex]
Put (-2,-1) in the above equations.
[tex]5(-2)=-10\Rightarrow -10=-10[/tex]
[tex]11(-2)-9(-1)=-13\Rightarrow -13=-13[/tex]
Since left hand side is equal to right hand side, therefore the point (-2,-1) satisfy the equations and (-2,-1) is the solution of the given system.
Similarly check the other system of equations, whether the point (-2,-1) stratify the equations or not.
In option 2,
[tex]2x+9y=-1[/tex]
[tex]2(-2)+9(-1)=-1\Rightarrow -13=-1[/tex]
Since left hand side is not equal to right hand side, therefore the point (-2,-1) is not the solution of this system of equation.
In option 3,
[tex]-6x+9y=-1[/tex]
[tex]-6(-2)+9(-1)=-1\Rightarrow 3=-1[/tex]
Since left hand side is not equal to right hand side, therefore the point (-2,-1) is not the solution of this system of equation.
In option 4,
[tex]-6x+3y=-1[/tex]
[tex]-6(-2)+3(-1)=-1\Rightarrow 9=-1[/tex]
Since left hand side is not equal to right hand side, therefore the point (-2,-1) is not the solution of this system of equation.
Only option 1 is correct.
Ryan, Jessica, and Mark each solved this system of equations. All of their answers are different. Find and explain the mistakes. What is the correct answer?
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.
6x - 2y = 10
-2y = -6x + 10
reduce by dividing by -2
y = 3x - 5
slope = 3 and y int = -5
y = 3x + 2
slope = 3, y int = 2
These lines are parallel. Parallel lines will have the same slope, but different y integers. There is no solution to this because the lines never intersect.
Mark's answer is correct

Sam bought 86 pounds of flour for his bakery. Every day he used the same amount of flour to make bakery items. After 10 days, Sam was left with 25.2 pounds of flour. On average, how many pounds of flour did Sam use each day?
86-25.2 = 60.8 pounds of flour used
60.8/10 = 6.08 pounds used per day
Answer:
6.08
Step-by-step explanation:
first, i subtracted 86 from 25.2 to get what he used in the 10 days, which was 60.8, then i would divide it by 10 bc of 10 days to get 6.08. Hope this helps!

Margie calculated that she would spend $175 on school supplies this year. She actually spent $97.50 on school supplies. What is Margie’s percent of error? 77.3% 79.5% 44.2% 4.4%
Margie’s percent of error is 79.5%.
First step is to calculate the amount that Margie was off by
Amount=$175 - $97.50
Amount=$77.5
Second step is to find Margie percent of error
Percent of error=77.5 / 97.50× 100
Percent of error = 79.48717949%
Percent of error=79.5% (Approximately)
Inconclusion Margie’s percent of error is 79.5%.
