A developer wants to develop a 25-acre subdivision. He figures that the streets and common area will take up about 35% of this o

verall area. If the minimum lot size is to be 25,000 SF, how many lots can the developer have on this property? 15 lots? 65 lots? 28 lots? 34 lots?

The amount avaliable for division into lots is
  25 ac - 0.35*25 ac = 0.65*25 ac = 16.25 ac
There are 43,560 ft² in an acre, so the number of possible lots is
  (16.25 ac)*(43,560 ft²/ac)/(25,000 ft²/lot) = 28.314 lots

The developer has enough area for 28 lots.

The following is a linear programming formulation of a labor planning problem. There are four overlapping shifts, and management
dexar [7]

Answer:

d. 15

Step-by-step explanation:

Putting the values in the shift 2 function

X1 + X2 ≥ 15

where x1=  13, and x2=2

13+12≥ 15

15≥ 15

At least 15 workers must be assigned to the shift 2.

The LP model questions require that the constraints are satisfied.

The constraint for the shift 2 is that the  number of workers must be equal or greater than 15

This can be solved using other constraint functions e.g

Putting  X4= 0 in

X1 + X4 ≥ 12

gives

X1 ≥ 12

Now Putting the value X1 ≥ 12  in shift 2 constraint

X1 + X2 ≥ 15

12+ 2≥ 15

14 ≥ 15

this does not satisfy the condition so this is wrong.

Now from

X2 + X3 ≥ 16

Putting X3= 14

X2 + 14 ≥ 16

gives

X2  ≥ 2

Putting these in the shift 2

X1 + X2 ≥ 15

13+2 ≥ 15

15 ≥ 15

Which gives the same result as above.

What is the length of BC ?
MrRa [10]
Looking at this triangle, we can see that is a form of a 45, 45, 90 triangle
This would mean that 2x-24=x-2
Solve: 2x-24=x-2
subtract x from both sides and add 24 to both sides...
x=22

There are 6 diagonals that can be drawn from one vertex of an octagon, true or false.
FinnZ [79.3K]
It's False; an octagon has 8 vertices. When you remove the starting vertex and the two adjacent vertices we're left with 5 possible diagonals

Which of the following is a conjugate for 7 + i Square root of 2? (2 points) − 7 + i Square root of 2 7 − i Square root of 2 i S
hammer [34]

Answer:

7-\sqrt{2}i

Step-by-step explanation:

Given number is 7+\sqrt{2}i. We need to find the complex conjugate of the given number.

We will use the general rule to find out the complex conjugate of the number.

The complex conjugate of a+bi will be a-bi

And the complex conjugate of 7+\sqrt{2}i\ became\ 7-\sqrt{2}i

So, the complex conjugate of 7+\sqrt{2}i is 7-\sqrt{2}i
