please help find the length of the wire used to construct the net
The length of the wire used to construct the net is approximately 127.2 cm.
What is length?Length is a measurement of distance, or the amount of space between two points. It is usually expressed in units such as meters, feet, or inches. Length is used in many fields, such as mathematics, physics, engineering, and architecture, to describe the size of objects, the distance between two points, and the area of a two-dimensional shape. Length is also used to measure time and speed.
This is found by using the formula for the circumference of a circle (2πr) and multiplying it by the length of the net (8 cm). Therefore, 2π(16 cm) x 8 cm = 127.2 cm.

can you form a triangle with side lengths of 3/8, 1 1/6 and 3/4?
Answer:
No
Step-by-step explanation:
for the sides to form a triangle then the sum of any 2 must be greater than the third.
\(\frac{3}{8}\) , 1 \(\frac{1}{6}\) , \(\frac{3}{4}\) ( change 1 \(\frac{1}{6}\) into an imprioper fraction )
\(\frac{3}{8}\) , \(\frac{7}{6}\) , \(\frac{3}{4}\)
rewrite each fraction with a denominator of 24 ( the LCM of 8,6,4 )
This will allow the fractions to be compared more easily.
\(\frac{9}{24}\) , \(\frac{28}{24}\) , \(\frac{18}{24}\)
\(\frac{9}{24}\) + \(\frac{28}{24}\) = \(\frac{37}{24}\) > \(\frac{18}{24}\)
\(\frac{28}{24}\) + \(\frac{18}{24}\) = \(\frac{46}{24}\) > \(\frac{9}{24}\)
\(\frac{9}{24}\) + \(\frac{18}{24}\) = \(\frac{27}{24}\) < \(\frac{28}{24}\)
the condition is not met for the 3 sides , so they do not form a triangle.

The value of x in this figure is equal to: D. 5.
How to determine the value of x?In Mathematics and Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:
Sum of interior angles = 180 × (n - 2)
Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.
Sum of interior angles = 180 × (5 - 2)
Sum of interior angles = 180 × 3
Sum of interior angles = 540°.
112 + 7x + 5 + 6x + 2 + 10x - 8 + 4x + 24 = 540°.
27x = 135
x = 135/27

Answer:
the speed value that the radar equipment outputs.
Step-by-step explanation:
A random variable in an experiment is also (and most times the case) called a dependent variable. In this scenario, the random variable would be the speed value that the radar equipment outputs. This is because this value depends on the actual velocity of the cars that pass by the equipment. The faster the car is moving when it passes the radar the higher value will be displayed on the equipment. Therefore, depending completely on the vehicles.
What is the area of the square that measures 3.1 m on each side
The area of the square with a side length of 3.1 meters is 9.61 square meters.
To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.
Area of a square = side length × side length
Substituting the given side length into the formula:
Area = 3.1 m × 3.1 m
To perform the calculation:
Area = 9.61 m²
It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.
Remember, to find the area of any square, you simply need to multiply the length of one side by itself.
The area of the square with a side length of 3.1 meters is 9.61 square meters.

A company paid $203.00 for an item. The original price was $291.10, but this was marked down 40%. If the operating expenses are 36% of the cost, find the operating loss and the absolute loss.
1. What is the operating loss?
2. What is the absolute loss?
Answer,:
Answer and Explanation: 1
1.
Calculation for operating loss is shown below:
Break-even point in dollars = Cost + Operating expenses
Break-even point in dollars = $208.40 + (36% * $208.40)
Break-even point in dollars = $208.40 + $ 75.024
Break-even point in dollars = $283.424
Reduced price = Original price - (Original price * Mark down)
Reduced price = $292.60 - ($292.60 * 40%)
Reduced price = $292.60 - $117.04
Reduced price = $175.56
Operating loss = Break-even point in dollars - Reduced price
Operating loss = $283.424 - $175.56
Operating loss = $107.864
2.
Calculation of absolute loss is shown below:
Absolute loss = Cost - Reduced price
Absolute loss = $208.40 - $175.56
Absolute loss = $32.84

Answer:
16m
Step-by-step explanation:
Separate the rectangle from the triangle. The area of the rectange is 10m. We know this because l x w (2m x 5m).
Now for the triangle;
The area of a triangle is b x h / 2. We take the full height of the figure and subtract 5 from it giving us 3 which is our height for the triangle. We then see that 2m is on the bottom and we add that 2m to the two separate 1m giving us 4m in total.
Now that we have the base and height of the triangle we plug in giving us 6m. Finally we add both the areas; 10m + 6m = 16m.

Write an equation of the line that passes through (−2,3) and (0,8).
An equation is y=
.
Answer:
Step-by-step explanation:
y = mx + b
b is the y intercept and occurs where x = 0. One of our select points has an x value of 0, therefore b = 8
m is the slope and is found as the change in y over the change in x
m = Δy/Δx = (8 - 3) / (0 - (-2)) = 5/2
y = 5x/2 + 8

The solution is

b) Yes , The result of A - B is also a polynomial
c) Yes , The result of A x B is also a polynomial
What is a polynomial?
Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients ( constants who are in multiplication with those variables ) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first polynomial be A
The value of A is 3x²( x - 1 )
Let the second polynomial be B
The value of B is -3x³ + 4x² -2x + 1
On simplifying the equations , we get
A = 3x³ - 3x²
B = -3x³ + 4x² -2x + 1
a)
Let the new polynomial be C
where the value of C = A + B
On substituting the values of A and B in the equation , we get
C = 3x³ - 3x² + ( -3x³ + 4x² -2x + 1 )
C = 3x³ - 3x³ - 3x² + 4x² - 2x + 1
C = x² - 2x + 1
So , the value of C is also a polynomial
b)
Let the new polynomial be C
where the value of C = A - B
On substituting the values of A and B in the equation , we get
C = 3x³ - 3x² - ( -3x³ + 4x² -2x + 1 )
C = 3x³ + 3x³ - 3x² - 4x² + 2x - 1
C = 6x³ - 7x² + 2x - 1
So , the value of C is also a polynomial
c)
Let the new polynomial be C
where the value of C = A x B
On substituting the values of A and B in the equation , we get
C = ( 3x³ - 3x² ) ( -3x³ + 4x² -2x + 1 )
C = -9x⁶ + 12x⁵ - 6x⁴ + 3x³ + 9x^5 - 12x⁴ + 6x³ - 3x²
C = - 9x⁶ + 19x⁵ - 18x⁴ + 9x³ - 3x²
So , the value of C is also a polynomial
Hence , the operations of addition, subtraction, multiplication of polynomials will result in a polynomial

Suppose there is a simple index of two stocks, stock A and stock B. Stock A opens on Monday with 5000 shares at $2.75 per share. Stock B opens on Monday with 3000 shares at $4.30 per share. Stock A opens on Tuesday at $3.10 per share, and stock B opens on Tuesday at $4.85 per share. Both stocks have the same number of shares that they opened with on Monday. What is the rate of change of this simple index over 1 day?
The rate of change of the simple index over one day is approximately 12.78%.
To calculate the rate of change of the simple index over one day, we need to determine the percent change in the total value of the index between Monday's opening and Tuesday's opening.
On Monday, Stock A has 5000 shares at $2.75 per share, so its total value is:
Total value of Stock A on Monday = 5000 * $2.75 = $13,750
Similarly, on Monday, Stock B has 3000 shares at $4.30 per share, so its total value is:
Total value of Stock B on Monday = 3000 * $4.30 = $12,900
The total value of the index on Monday is the sum of the values of Stock A and Stock B:
Total value of the index on Monday = $13,750 + $12,900 = $26,650
On Tuesday, Stock A opens at $3.10 per share, and Stock B opens at $4.85 per share. Both stocks still have the same number of shares as on Monday.
The total value of Stock A on Tuesday is:
Total value of Stock A on Tuesday = 5000 * $3.10 = $15,500
The total value of Stock B on Tuesday is:
Total value of Stock B on Tuesday = 3000 * $4.85 = $14,550
The total value of the index on Tuesday is the sum of the values of Stock A and Stock B:
Total value of the index on Tuesday = $15,500 + $14,550 = $30,050
To calculate the percent change in the index, we use the formula:
Percent Change = ((New Value - Old Value) / Old Value) * 100
Percent Change = (($30,050 - $26,650) / $26,650) * 100 ≈ 12.78%
