When a solution to the linear programming problem satisfies all the constraints, including the nonnegativity conditions, it is considered a. Feasible b. Semi-feasible c. Infeasible d. Unbounded
A solution to a linear programming problem is considered feasible when it satisfies all the constraints, including the nonnegativity conditions. This means that the values of the variables must be greater than or equal to zero. Therefore, the correct answer is (a) Feasible.
What is linear programming?A linear programming problem is an optimization problem consisting of linear equations and constraints that must be solved simultaneously. The goal of linear programming is to maximize or minimize a particular value (such as profit or cost) by finding the optimal combination of different variables. When a solution to the linear programming problem satisfies all the constraints, including the nonnegativity conditions, it is considered a feasible solution.

How do I solve for the measures of the the interior angles of a polygon
Answer:
Step-by-step explanation:
To solve for the interior angles for a polygon,
subtract 2 from the number of sides then multiply with 180
i.e, (n-2)180
e.g, in the case of a triangle, (3-2)180 = 1*180 = 180
As for square, (4-2)180 = 2*180 = 360

Work out the value of (6.8 × 10²) x (1.3 x 10^-3)
Give your answer in standard form.
The standard form of the given expression (6.8 × 10²) x (1.3 x 10⁻³) is 0.884.
What exactly is a mathematical standard form?
A number can be written in a certain style that adheres to regulations, which is known as its standard form. Standard form refers to any number between 1.0 and 10.0 that may be expressed as a decimal number and multiplied by a power of 10.The given expression is (6.8 × 10²) x (1.3 x 10⁻³)
We can rewrite the expression as (6.8 * 1.3) (10² * 10⁻³)
Now multiply;
= (8.84) * (10² * 10⁻³)
Apply the exponent property: xᵃᵇ = xᵃ⁺ᵇ
= 8.84 * (10²⁺⁽⁻³⁾)
= 8.84 * 10⁻¹
Now, 10⁻¹ = 1/10
= 8.84/10
= 0.884
Hence, the standard form of the given expression (6.8 × 10²) x (1.3 x 10⁻³) is 0.884.

Step-by-step explanation:
1) Total rectangle area = W x H = 12 x 8 = 96 cm^2
area of triangle (shaded portion) = 1/2 base * height = 1/2 * 7 x 8 = 28 cm^2
Nonshaded portion = 96 - 28 cm^2 = 68 cm^2
ratio shaded:nonshaded is then 28 : 68 = 7:17
2) Look at the two middle triangles : Height of each = 8 cm
then reading across the diagram height + base + height = 21 cm
so base = 5 cm
area of ONE triangle = 1/2 * base * height = 1/2 * 5 * 8 = 20 cm^2
total area for FOUR of them = 80 cm^2

Jesus works at a computer outlet. He receives a bi-weekly salary of
$300 plus 5. 5% commission on his sales. In the last two weeks, he sold
$16,200 of computer equipment. He pays 8% for State Income Tax,
12. 3% for Federal Income Tax, 6. 3% for Social Security, and 1. 45%
for Medicare. What steps did I take to find Jesus' net bi-weekly
pay? (Show your work)
Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.
To find Jesus' net bi-weekly pay, I followed these steps:
Calculate Jesus' commission: Jesus sold $16,200 of computer equipment, so his commission is 5.5% of $16,200, which is $891.
Calculate Jesus' gross bi-weekly pay: Jesus receives a bi-weekly salary of $300 plus his commission of $891, so his gross bi-weekly pay is $1,191.
Calculate Jesus' deductions: Jesus pays 8% for State Income Tax, 12.3% for Federal Income Tax, 6.3% for Social Security, and 1.45% for Medicare. To calculate the deductions, I multiplied his gross bi-weekly pay by each percentage rate:
State Income Tax: 8% of $1,191 = $95.28
Federal Income Tax: 12.3% of $1,191 = $146.67
Social Security: 6.3% of $1,191 = $75.09
Medicare: 1.45% of $1,191 = $17.27
Subtract the deductions from the gross bi-weekly pay: To find Jesus' net bi-weekly pay, I subtracted the total deductions of $334.31 from his gross bi-weekly pay of $1,191:
Net bi-weekly pay = $1,191 - $334.31 = $856.69
Therefore, Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.

Autumn creates bracelets as a hobby and is planning to start selling them online for $10 per bracelet. Autumn has already sold 5 custom bracelets. Her bracelets are so popular that she expects to sell every bracelet that she makes. Write an equation for the amount of money Autumn makes. If Autumn makes and additional 24 bracelets, how much money will she make?
Answer: $290
Step-by-step explanation:
Cost per bracelet = $10
5 bracelets sold x $10/bracelet = $50 cash earned already
x = number of bracelets sold
Money made = (x )($10/bracelet)
Total money made if Autumn sells 24 more bracelets:
$50 + (24)($10) = $290

Equations and expressionsEquations are expressions separated by an equal sign.
Given the expression
x/2 - (5x-3)/12 = 1/3 x - 0.75
Find the LCM
6x-(5x-3)/12 = 1/3 x - 0.75
(x+3)/12 = 1/3 x - 0.75
(x+3)/12 - x/3 = -0.75
(x+3-4x)/12 = 0.75

Enter the correct answer in the box. The graph shows function j, a transformation of f(x)= x^1/2
The required equation function j which is the transformation of \(f(x)= x^{1/2}\) is \(j(x)= (x+2)^{1/2}\) .
As we can see in the graph the functions j and f are similar but the graph of j is 2 units left of f. So, function f(x) has a domain of real number greater than equal to zero, while as the function j is 2 units left of f then its equation is given as \(j(x)= (x+2)^{1/2}\) where the domain of j is all real numbers greater then or equal to -2.
Thus, the equation of function j is the transformation of \(f(x)= x^{1/2}\) is \(j(x)= (x+2)^{1/2}\) .

determine the net displacement of a particle in motion from t=0 to t=4 given that the velocity function for the particle is v(t)=−3t 8 m/sec. do not include any units in your answer.
The net displacement of the particle in motion from t=0 to t=4 given that the velocity function for the particle is v(t)=−3t 8 m/sec is 8 meters.
To determine the net displacement of a particle in motion from t=0 to t=4 with the velocity function v(t) = -3t + 8 m/sec, follow these steps:
1. Integrate the velocity function to find the displacement function. The displacement function, s(t), represents the particle's position at a given time t.
2. Calculate the displacement at t=4 and t=0 using the displacement function.
3. Subtract the displacement at t=0 from the displacement at t=4 to find the net displacement.
Integrate the velocity function
∫(-3t + 8) dt = -1.5t^2 + 8t + C, where C is the integration constant.
Calculate the displacement at t=4 and t=0
s(4) = -1.5(4)^2 + 8(4) = -1.5(16) + 32 = -24 + 32 = 8
s(0) = -1.5(0)^2 + 8(0) = 0
Find the net displacement
Net Displacement = s(4) - s(0) = 8 - 0 = 8
Therefore, the net displacement of the particle in motion from t=0 to t=4 is 8 meters.

Answer:
x = 120
Step-by-step explanation:
All three angles are marked as equal. There are two ways to find x.
Method one
Find the supplement to x
Let the supplement to x be y
y + y + y = 180
3y = 180 Divide by 3
y = 180/3
y = 60
=================
A straight line has an angle of 180 degrees.
x + y = 180 Substitute y = 60 into the equation
x + 60 = 180 Subtract 60
x = 180 - 60
x = 120
Method 2
The two angles not connect to x are called remote interior angles. These two angles are equal to x.
x = 60 + 60
x = 120

If you wanted to find the difference of 6/25-4/5,what common denominator should you choose?why?
Answer:
25
Step-by-step explanation:
25 should be chosen as the common denominator. 5 is a possible common denominator because the other fraction has a denominator of 5 and 25 is divisible by 5, however, the numerator cannot be evenly divided by 5. Attempting to do so would cause a much more difficult equation. On the other hand, the denominator 5 can be changed to 25 by multiplying by 5, and 4 can also be changed by multiplying by 5.
4/5 x 5 = 20/25
6/25 - 20/25 = -14/20 = -7/10
