Answer:
2.829 mm
Step-by-step explanation:
Correct: 2.83 mm
Measured(mm) Difference (mm)
2.837 0.007
2.829 -0.001 Smallest deviation from actual.
2.812 -0.018
2.805 -0.025
The measurement of the piece of metal that is the most accurate is 2.837 cm.
Given that,A piece of metal with a length of 2.83 cm was measured using four different devices.
We have to determine,Which of the following measurements is the most accurate?
According to the question,A piece of metal with a length of 2.83 cm was measured using four different devices.
Accuracy is the degree to which the measured value is close to the correct value.
The difference between the accepted value and the measured value of the quantity is called the error of measurement.
The measurement for the first device is,
[tex]=2.83 - 2.837\\\\=-0.007[/tex]
The measurement of the first device is -0.007.
The measurement for the second device is,
[tex]=2.83 - 2.829\\\\=-0.001[/tex]
The measurement of the second device is -0.001.
The measurement for the third device is,
[tex]=2.83 - 2.812\\\\=-0.018[/tex]
The measurement of the third device is -0.018.
The measurement for the fourth device is,
[tex]=2.83 - 2.805\\\\=-0.025[/tex]
The measurement of the fourth device is -0.02.
Hence, The measurement that is the most accurate is 2.837 cm.

What is the perimeter of â–łJKL? 6 9. 5 11. 5 19.
The perimeter of the rectangle IJKL is 16units.
Since we are not given a diagram, we can assume the diagram is a rectangle IJKL with the following parameters:
Length = 3 units
Width = 5 units
The formula for finding the perimeter of a rectangle is expressed as:
P = 2(L + W)Substitute the given values to have:
P = 2(3 + 5)
P = 2(8)
P = 16 units
Hence the perimeter of the rectangle IJKL is 16units.
Note that this formula is applicable to any rectangle given.

Nancy's nut shop sells cashews for $5.30 per pound and peanuts for $2.80. How many pounds of peanuts must be added to 20 pounds of cashews to make a mix that sells for $3.30 per pound?
Answer:
80 pounds
Step-by-step explanation:
let 'p' = pounds of peanuts to be added
20(5.3) + 2.8p = 3.3(20 + p)
106 + 2.8p = 66 + 3.3p
40 = 0.5p
p = 80

if 5(2x-1)=35,then x=
Answer:
x=4
Step-by-step explanation:
5(2x - 1) = 35
Should expand so....
10x - 5 = 35
10x = 40
x = 4
Answer:
x=4
Step-by-step explanation:
distribute the 5: 10x-5=35
add 5 to both sides: 10x=40
divide both sides by 10: x=4
A relation is plotted as a linear function on the coordinate plane starting at point E at(0, 27)and ending at point F at (5, â’8). What is the rate of change for the linear function and what is its initial value? Select from the drop-down menus to correctly complete the statements. The rate of change for the linear function is Choose. And the initial value is Choose. .
The rate of change of a linear function is the slope of the function.
The rate of change is -7 and the initial value of the function is 27
The points are given as:
[tex]E = (0,27)[/tex]
[tex]F = (5,-8)[/tex]
The slope (m) is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{-8 - 27}{5-0}[/tex]
Rewrite the fraction as:
[tex]m = \frac{- 35}{5}[/tex]
Divide -35 by 5
[tex]m = -7[/tex]
So, the rate of change is -7
The initial value of the function is the value of the function when the input value (i.e. x) is 0.
At point E, we have: [tex]E = (0,27)[/tex]
So, the initial value of the function is 27

Answer:
9. the first one ( 12 + 4 = 4 + 12 )
Step-by-step explanation:
the commutative property of addition means that you can change the order of the numbers you add and the sum will still be the same. this is shown in the 12 + 4 = 4 + 12 because the order is switched, but they are still equal.
The example of the commutative property of addition is 12 + 4 = 4 + 12, the correct option is A.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The four options
Now,
The commutative property of addition states that changing the order of the addends does not change the sum.
This is the only option that shows the same sum with different orders of addends.
Therefore, by algebra the answer will be 12 + 4 = 4 + 12.

what is the slope
Answer:
there is no slope
Step-by-step explanation:
you cannot divide by zero
Answer:
slope is undefined
Step-by-step explanation:
The slope is the difference in y divided by the difference in x.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
That is the 2nd point's value minus the first, where the points are (x1, y1) and (x2, y2)
Given these 2 points, calculate the slope:
[tex]m=\frac{-1--5}{4-4}\\\\m=\frac{4}{0}[/tex]
In this case, the slope is undefined. A function cannot have multiple outputs for the same input, and an undefined slope has infinite outputs for 1 input. You can see that in the attached image, it's a vertical line.
Find the slope of the line that passes through (84, 7) and (85, -25). Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer: The slope is -32
Explanation:
Start with the slope formula:
m= (y2 - y1) / (x2 - x1)
Substitute point values in the formula
m = (-25 - 7) / (85 - 84)
Simplify each side of the equation
m= (-25 - 7) / (85 - 84) = -32/1
Solve for slope (m)
m= -32

Divide £520 in the ratio 6:7
The ratio of the number 520 in 6: 7 will be 240: 280.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the number 520 is divided into the ratio 6: 7.
The number in the ratio 6:7 will be divided as;-Let the constant term for the ratio is x now form an equation and solve.
6x + 7x = 540
13x = 540
x = 540 / 13
x = 40
6x = 40 x 6 = 240
7x = 7 x 40 = 280
