A landlord is considering upgrades and repairs, including wood floors, kitchen tile, a new back door, and a repaired garage door. The landlord could do these things himself or hire a contractor. The contractor could finish the job in half the time but would charge more. The landlord wants to leave the choice of whether to actually upgrade the kitchen tile up to the optimization algorithm. How should this constraint be written if he uses the following scheme for decision variables? x1 = contractor works on wood floors x2 = landlord works on wood floors x3 = contractor works on kitchen tile x4 = landlord works on kitchen tile x5 = contractor works on back door x6 = landlord works on back door x7 = contractor works on garage door x8 = landlord works on garage door Group of answer choices x3+ x4≤ 1 x3+ x4= 1 x3- x4= 1 x3- x4≤ 1

Answers

Answer 1

Answer:

x3 + x4 ≤ 1

Step-by-step explanation:

Upgrades considered = wood floors, Kitchen tile, New back door and a repaired garage

The constraint of whether to upgrade the kitchen either by the landlord or by  a contractor can be represented with the scheme below:

x3 + x4 ≤ 1

The constraint is written this way because  only one scheme can be used at a time i.e when x3 = 1 , x4 = 0 and vice versa. also

note that both x3 and x4 can be = 0.  because the upgrade of the kitchen tiles is under probability and the landlord might decide not to upgrade the kitchen tiles hence both schemes ( x3 and x4 ) can be = 0

If you had a bank that offered 6.1% interest and compounded money 4 times a year, how many years would go by until you could turn $6000 into enough to buy a brand new car ($12,000)?

Answers

Answer:

t = 11.45 years

Step-by-step explanation:

A = p(1+r/n)^nt

A = future value = $12000

P = present value = $6000

n = number of periods = 4

r = interest rate = 6.1% = 0.061

t = number of years = ?

t = log(A/P) / n[log(1 + r/n)]

= log(12000/6000) / 4[log(1+0.061/4)]

= log(2) / 4[log(1 + 0.01525)]

= 0.3010 / 4[log(1.01525)]

= 0.3010 / 4(0.00657)

= 0.3010 / 0.02628

= 11.45 years

Determine whether this picture is an example of a function, relation, function and relation, or neither relation nor function

B:Relation only
C:Neither function nor relation
D:Function and relation

Answers

Answer:

C:Neither funtion nor relation

C:Ni función ni relación

espero que te sirva marcarme como mejor respuesta PORFA y gracias

Answer:

relation only

Step-by-step explanation:

A relation is a set of one or more ordered pairs.

A function is a relation in which each element of the domain is paired with EXACTLY one element of the range.

The Vertical-Line Test: Given the graph of a relation, if a vertical line can be drawn that does not cross the graph in more than one place, it is a function.

Any vertical line drawn where x > -4 will cross the graph in more than one place.

Therefore, the graph is not a function, it is a relation only.

Two supplementary angles. One angle is 25 more than the second angle, find the measure of the second angle. The measure of the second angle is

Answers

Answer:

  77.5°

Step-by-step explanation:

Let s represent the measure of the second angle. Then the first angle is s+25. These two angles are supplementary, so their sum is 180:

  (s+25) +s = 180

  2s = 155

  s = 77.5

The measure of the second angle is 77.5°.

Jerry can frame a room in 1 hour, while Jake takes 4 hours. How long would it take for them to frame a room working together?

Answers

Answer:

45 minutes

Step-by-step explanation:

If two people work together, the time it takes to frame will obviously be shorter. Since Jake Takes four times longer, he will only cut off a fourth of Jerry's time. Which is 15 mins. 60 mins - 15 mins = 45 mins.

The least common multiple that is divisible by both a and b is the smallest positive integer. It will take 4/5 hours for Jerry and Jake to frame a room working together.

What is LCM?

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

Jerry can frame a room in 1 hour. Therefore, the rate at which Jerry frame the room is,

Rate of Jerry = 1/1 room per hour

                      = 1 room per hour

Jake can frame a room in 4 hours. Therefore, the rate at which Jake can frame the room is,

Rate of Jake = 1/4 room per hour

Now, the rate at which they two will work together is,

Rate of working together = 1 + 1/4 room per hour

                                           = 5/4 room per hour

Further, the time it will take for the two of them to frame a room working together is,

Time = 1/Rate

         = 4/5 hour

Step-by-step explanation:

The slack variables make up the difference between the sum of the utilizations and the limit. A separate slack variable is needed for each limit. As with the other variables, its minimum value is zero.

For ( ) ≤ lim constraints, the slack variables are on the left side of the equal sign:

  ( ) +s ≤ lim.

__

For ( ) ≥ lim constraints, the slack variables can be on the right side of the equal sign:

  ( ) = s + lim

The more usual representation in a linear programming matrix is ...

  ( ) - s = lim

Here, your constraints are "≤", so each equation will have a unique slack variable added to the left side sum.

What is the equation that can be used to determine the cost of each movie ticket?

Total cost of the 6 movie tickets = (6 x cost of each ticket) - value of one coupon

50.50 = 6C - $2
