Answer:

Step-by-step explanation:

The cost per sandwich when 3 are delivered is $20/3 or $6.67 each.

The cost per sandwich when 4 are delivered is $26/4 or $6.50 each.

The average cost per sandwich changes with the number delivered, so it is not proportional.  The cost decreases per sandwich as the volume of sandwiches increases.  One can't predict the cost of 6 delivered sandwiches based on the information provided.  If it were proportional, the cost could be calculated on the basis of the slope of the line.  If all sandwiches cost $6.50 each, regardless of the volume ordered, the slope of a line relating number ordered and total cost would have a constant slope of 6.50.  That isn't the case in this problem.  The slope keeps changing.

Horizontal pieces can be produced at a rate of 200 per labor hour. a carpenter uses 500 horizontal pieces and 22 vertical pieces
ira [324]
  1. The number of vertical pieces will be 28. Then the correct option is A.
  2. The number of horizontal pieces will be 600. Then the correct option is B.
<h3>What is decision-making?</h3>

The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.

Horizontal pieces can be produced at a rate of 200 per labor hour.

A carpenter uses 500 horizontal pieces and 22 vertical pieces while making racks for an hour.

You have 900 horizontal pieces and 50 vertical pieces in stock right now.

For the next hour, you assign Juan to rack making, Debbie to trim making, and both mike and stan to horizontal piece production.

1.  Then at the end of the next hour, the number of vertical pieces available in stock will be

→ 50 - 22

→ 28

Thus, the number of verticle pieces will be 28.

2.  Then at the end of the next hour, then the number of horizontal pieces available in stock will be

→ 900 + 200 - 500

→ 600

More about the decision-making link is given below.

What is the slope of the graph?
Dennis_Churaev [7]

Answer:

-4

Step-by-step explanation:

Slope can be found with \frac{y2-y1}{x2-x1}

Pick two points on the graph that the line runs through

(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2

Insert the coordinates into the formula

\frac{0-4}{(-1)-(-2)}

\frac{-4}{-1+2}

\frac{-4}{1}

Therefore the slope is -4

Find the unit vector in the direction of v=(7,-3).<br> (enter exact answers with square roots)
navik [9.2K]

Answer:

\binom{ \frac{7 \sqrt{58} }{58} }{  \frac{ - 3 \sqrt{58} }{58} }

Step-by-step explanation:

First, find the magnitude of the vector:

|v|  =  \sqrt{( {(7)}^{2} + {( - 3)}^{2})  } \\  =  \sqrt{(49 + 9)}  \\   =  \sqrt{58}

Then, divide each component of the vector by the magnitude to get the unit vector and rationalise:

unit \: vector =  \binom{ \frac{7}{ \sqrt{58} } }{ \frac{ - 3}{ \sqrt{58} } }  \\  =  \binom{ \frac{7 \sqrt{58} }{58} }{  \frac{ - 3 \sqrt{58} }{58} }
