Answer: \frac{3,000}{A}

Step-by-step explanation:

<h3> Since the figure is not attached, below you can see a general explanation of the procedure to solve the exercise: </h3>

For this exercise you can apply the following formula, which is used to calculate the area of a trapezoid:

A=\frac{h(B+b) }{2}

Where  "B" and "b" are the bases of the trapezoid and "h" is the height.

So, substituting values into the formula and evaluating, you can find the area of  trapezoid-shaped region.

Since the population in the trapezoid-shaped region is about 3,000 people, you can find the number of people per square mile dividing the population by the area of the region.

Then, the following expression represents the number of people per square mile in that region:

\frac{3,000}{A}

Answer:

60

Step-by-step explanation:

Find the area of the trapezoid by using the formula: A= 1/2h(b1+b2)

divide 3000/A = 3000/50 = 60 people per square mile.

<u>Geometry</u>

Volume of a Prism Formula: V = lwh

  • <em>l</em> is length
  • <em>w</em> is width
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>l</em> = 13.8 cm

<em>w</em> = 4.5 cm

<em>h</em> = 5 cm

<u>Step 2: Solve for </u><em><u>V</u></em>

  1. Substitute in variables [Volume of a Prism Formula]:                                    V = (13.8 cm)(4.5 cm)(5 cm)
  2. Multiply:                                                                                                             V = (62.1 cm²)(5 cm)
  3. Multiply:                                                                                                             V = 310.5 cm³

Step-by-step explanation:

y – 1 = 2(x – 2)

Distribute

y-1 =2x-4

Add 1 to each side

y-1+1 = 2x-4+1

y = 2x-3

Four times the sum of three consecutive odd integers is seven hundred sixty-five less than three times the product of the larger
Andre45 [30]

Answer:

The consecutive odd integers are (15, 17, 19) or (-17, -15, -13).

Step-by-step explanation:

Let the three consecutive odd integers be: x-2,x\ and \ x+2

The condition given is:

4[x-2+x+x+2]=3x(x+2)-765

Solve this for <em>x</em> as follows:

4[x-2+x+x+2]=3x(x+2)-765\\4\times 3x=3x^{2}+6x-765\\3x^{2}-6x-765=0\\x^{2}-2x-255=0\\x^{2}-17x+15x-255=0\\x(x-17)+15(x-17)=0\\(x-17)(x+15)=0

  • If (x-17)=0 then the value of <em>x</em> is 17.

       The odd numbers are:

          x-2=17-2=15\\x=17\\x+2=17+2=19

  • If (x+15)=0 then the value of <em>x</em> is -15.

       The odd numbers are:

         x-2=-15-2=-17\\x=-15\\x+2=-15+2=-13

Thus, the consecutive odd integers are (15, 17, 19) or (-17, -15, -13).
