Each small surfboard requires 3 hours to assemble, 2 hours to finish, and 1 hour for inspection. Each large surfboard requires 4 hours to assemble, 3 hours to finish, and 1.5 hours for inspection. There are 140 hours available for assembly, 100 hours to finish, and 50 hours for inspection. The large surfboard makes $150 profit per board. The small surfboard makes $100 profit per board.Linear programming will be used to create the weekly production schedule.What would be a constraint for this problem if S

If 4 units equal 12 inches, what is the value of 1 unit

Answers

Answer:

1 unit = 3 inches

Step-by-step explanation:

We are given that 4 units = 12 inches.

This can be rewritten as 4x = 12

Then to solve for x, you divide 4 on both sides

so x = 12/4

x = 3

Let me know if you have any questions

Answer:

3 inches

Step-by-step explanation:

4 units = 12 inches

1 unit = 12 ÷ 4 = 3 inches

Greg has a piece of rope 18 ft long. He wants to cut it into two pieces so that the longer piece (y) is 2 ft less than 3 times the length of the shorter piece (x).
Choose the two equations that will create our system of equations for this story problem.


A) x - y = 18

B) y = 2 - 3x

C) x + y = 18

D) y = 3x - 2

Answers

Answer:

The required equations are:

C) x + y = 18

D) y = 3x - 2

Step-by-step explanation:

Let x be the length of shorter piece and y be the length of larger piece

It is given that the total length is 18 ft which gives us our first equation

[tex]x+y = 18[/tex]

Now it is also given that

"3 times the length of the shorter piece (x)"

[tex]3x[/tex]

"2 ft less than 3 times the length of the shorter piece (x)"

[tex]3x-2[/tex]

Second equation will be:

[tex]y = 3x-2[/tex]

Hence, the required equations are:

C) x + y = 18

D) y = 3x - 2

Which of the polynomial equations cannot be solved using the quadratic formula?

Answers

Answer:

The polynomial equation that cannot be solved using the quadratic formula: Option2: [tex]x^2-2x^3-5=0[/tex]

Step-by-step explanation:

First of all we have to learn what a quadratic polynomial is.

A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.

The quadratic equation is of the form:

[tex]ax^2+bx+c = 0[/tex]

From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.

Hence,

The polynomial equation that cannot be solved using the quadratic formula: Option2: [tex]x^2-2x^3-5=0[/tex]

Here an easy question for points it’s a few but they easy

Answers

Answer: See explanation

Step-by-step explanation:

3.) 140 and its supplementary angle form a straight line, basically, they sum up to 180°. That angle is y

y + 140 = 180

Subtract both sides by 140

y = 40°

Seems both angles are congruent since they have the same label.

y + x + x = 180°

40 + 2x = 180

Subtract both sides by 40

2x = 140

Divide both sides by 2

x = 70°

4.) The missing angle = y

2x - 14 + 3x + 2 + y = 180

5x - 12 + y = 180

Subtract 5x from both sides

-12 + y = - 5x + 180

Add 12 to both sides

y = -5x + 180 + 12

y = -5x + 192

3x + 2 + 2x - 14 - 5x + 192 = 180

3x + 2x - 5x + 2 - 14 + 192 = 180

0 + 180 = 180

180 = 180

That's correct I guess.

5.) Missing angle = y

2x + 8 + 5x + y = 180

7x + 8 + y = 180

Subtract 7x from both sides

8 + y = -7x + 180

Subtract 8 from both sides

y = -7x + 180 - 8

y = -7x + 172

2x + 8 + 5x - 7x + 172

2x + 5x - 7x + 8 + 172 = 180

0 + 180 = 180

180 = 180

I.. think that's correct..?

6.) Missing angle = y

134 + y = 180

Subtract 134 from both sides

y = 46°

x + 46 + 22 = 180

x + 68 = 180

Subtract 68 from both sides

x = 112°
