The compound inequality is $176.40 ≤ t ≤ $352.80 if a construction worker earns an average bi-weekly net pay of $1,764.00 option (A) Is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

A construction worker earns an average bi-weekly net pay of $1,764.00.

= 10% of 1764

= (10/100)1764

= $176.4

= 20% of 1764

= (20/100)1764

= $352.8

Inequality will be: $176.40 ≤ t ≤ $352.80

Thus, the compound inequality is $176.40 ≤ t ≤ $352.80 if a construction worker earns an average bi-weekly net pay of $1,764.00 option (A) Is correct.

Answer:

$382.20 ≤ t ≤ $764.40

Step-by-step explanation:

Hello, so first we would need to convert bi-weekly pay to monthly income.

First we would times $1,764.00 by 26

1764.00 × 26 = 45864

Then we would divide 45864 by 12

45864 ÷ 12 = 3822.

Then we calculate how much the worker can spend  if their monthly budget for food is in between 10% and 20%

3822 ×  10% = 382.20

3822 × 20% = 764.40

So, we can see the correct answer is $382.20 ≤ t ≤ $764.40.

The number of gallons of gas which Mrs. Josey and her family would need is; 17.5 gallons of gas.

It follows from the task content that the quantity of gas in gallons needed by Mrs. Josey and her family to make it to Dallas is to be determined.

Therefore, since one gallon of gas is enough for 20 miles, It follows that the amount of gas required for 350 miles can be determined by proportion as follows;

20/1 = 350/x

x = 350 / 20

x = 17.5 gallons of gas.

Ultimately, the amount of gas needed for Mrs. Josey and her family to make it to Dallas is; 17.5 gallons of gas.

The present age of Tom is 12 years old

Jan is five years older than Tom

The age of Tom = x

The age of Jan = x + 5

After 3 years

The age of Tom = x + 3

The age of Jan = x + 5 + 3

= x + 8

The Tom's age is 3/4 of Jan's age

Then the equation will be

x + 3 = 3/4(x + 8)

Apply distributive property

x + 3 = (3/4)x + 6

x - (3/4)x = 6 - 3

Subtract the terms

1/4 x = 3

Move 1/4 to the right hand side of the equation

x = 3 ÷ 1/4

x = 3 × 4

According to the law of exponent, the value of positive exponent is greater than the negative exponent, this defines that they are not equal.

Exponent

Exponent refers the number of times a number is multiplied by itself.

Given,

Here we need to verify that, if  two expressions with exponents are a perfect match except one has a negative exponent and the other has a positive exponent, like 5³ and 5⁻³, then how does the exponent change the meaning of the expression.

According to the following law of the exponent, the positive exponent can be written as,

5³ = 5 x 5 x 5 = 125

Similarly, the negative exponent is written as,

5⁻³ = 1/5³

Which can be simplified as,

1/125 = 0.008

Therefore, when we compare these values, the value of positive exponent is greater than the negative exponent.

Thus, defines that the value of positive and negative exponent are not same.

Answer: b ≈ 74.605 meters

Step-by-step explanation:

    Let b be the length of the blue rope, r be the length of the red rope, and g be the length of the green rope. We will write different equations to show the situation given.

         b =  2r

         g = 8b

         b + r + g = 708.75 meters

Slope intercept form is achieved by isolating y to one side. 3x-6y=18: given. -6y=-3x+18: algebra. y=3/6x-3: simplifying.

Considering the given scatter plot, it is found that:

a. The line of best fit is: y = -0.245x + 5.59.

b. The correlation coefficient is: r = -0.57.

c. The interpretation of the correlation coefficient is of: There is a negative association between y and x.

d. The estimate of y when x = 12 is of: 2.65

A scatter plot is a set of points of a data-set, and these points are used to calculate both the correlation coefficient and the line of best fit.

For this problem, the points are given as follows:

(0,5), (1,7), (2, 6), (3, 4), (4, 3), (5,5), (6,4), (7,2), (8,5), (9,3), (10,4).

Inserting these points into a linear regression calculator, the line of best fit is given as follows:

y = -0.245x + 5.59.

Hence the estimate of y when x = 12 is obtained as follows:

y = -0.245(12) + 5.59 = 2.65.

Inserting these points into a correlation coefficient calculator, the correlation coefficient is given as follows:

r = -0.57.

The interpretation is that there is a negative association between y and x, which is neither strong neither weak, as the absolute value of the coefficient is close to the threshold of 0.6.

The sinusoidal equation for the graph in terms of Y, the temperature in degrees Celsius) and the time, T in hours is; Y = 3·sin((π/12)·(T + 6)) + 15

A sinusoidal equation or function is an oscillating and periodic function that is based on the sine of an angle.

The function of the graph is a sinusoidal function with the parts;

a = The amplitude

b = The frequency = 1/T

T = The period of the function

k = The vertical shift of the function

h = The horizontal shift of the function

From the graph, we have;

The minimum  point on the graph of the function = (1, 12)

The maximum point on the graph of the function = (13, 18)

The amplitude of the graph a is therefore; a = (18 - 12)÷2 = 3

The period of the graph = 1/b

1 cycle is completed in 24 hours, which indicates that the frequency of the function is; f = 2·π/24 = π/12 = b

The vertical shift, k from the parent function, y = sin(x) which is the distance the midline of the graph is raised above the x-axis is; k = 15

sin((π/12)·(0 - h)) = -1

((π/12)·(0 - h)) = -π/2

1) The y-intercept is 15,000.

2) The y-intercept represents the number of bacteria when treatment began.

3) The asymptote indicates that as time increases, the number of bacteria approaches 0.

The general formula for an exponential function is;

y = aˣ

Now, an asymptote of a curve is defined as a line that exists in a way that the distance that exists between the curve and the line approaches zero as either one or both of the x or y coordinates approaches to infinity.

From the given graph, we can say that the y-intercept which is where the curve intersects the y-axis is 15,000 and this indicates the number of bacteria that existed prior to treatment.

EDC = 56 degrees

Step-by-step explanation:

triangle OED is isosceles : base angles are congruent

2 * EDC + 68 = 180

2 * EDC = 180 - 68

2 * EDC = 112

2/2 EDC = 112/2

EDC = 56 degrees

Step-by-step explanation:

Triangle DOE is isosceles. So OED and ODE has same angle.

Total angle for isosceles triangle is 180.

ODE + OED = 180 - 68 = 112

OED = ODE = 112 /2 = 56

In the given ΔDEF x is 17 units and y is 2 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

Given, GH is the midpoint of ΔDEF and EF is the base of the ΔDEF with a length of 28 units.

We know the midpoint of ΔDEF is (1/2) EF.

∴ GH = (28/2) = 14 units.

Now GH = x - 3.

14 = x - 3.

x = 17.
