Population density is the number of people per unit of area. What is the population density of a state that has 1,627,260 people
Tresset [83]

Answer:

             = 1092 people/ sq mile  

Step-by-step explanation:

Population density is the number of people per unit of area.


We know the population is 1627260

The are is 1490 mi ^2

Population density = 1627260/1490

                                 =1092.120805  people / sq mile

Round to the nearest whole number

                                  = 1092 people/ sq mile

Find the volume of the cylinder. Use 3.14 for s. Round your answer to the nearest hundredth.
serg [7]

Answer:

2255.31 cu.m

Step-by-step explanation:

Volume of a cylinder = πr²h

Given radius r = 6.5m

Height h = 17m

Volume = π × 6.5²×17

Volume = 3.14×6.5²×17

Volume of the cylinder = 2255.31cu.m

A suitcase measures 24 inches long and -8 i aches high. What is the diagonal length of the suitcase? (Pythagorean Theorem)
BartSMP [9]

Answer:

Diagonal Length = 8\sqrt{10}  inches

Step-by-step explanation:

The suitcase is a rectangle with one side being 24 and another side being 8.

The diagonal is the line through the middle connecting two opposite corners.

If we draw the diagonal, it creates a triangle with one leg being 24 and another being 8.

The diagonal is the "hypotenuse" of the triangle.

Now, the pythagorean theorem:

leg^2 + another leg^2 = hypotenuse^2

So, we substitute the values known and find the hypotenuse (which is length of the diagonal). Shown below:

24^2+8^2=h^2\\640=h^2\\h=\sqrt{640}\\h=\sqrt{64*10}\\h=\sqrt{64}\sqrt{10}\\h=8\sqrt{10}

We have written the answer in exact form (with radical in simplified term).

We also use the radical property  \sqrt{a*b}=\sqrt{a}\sqrt{b}

The night school auditorium is able to seat 8 elementary school groups of 65 students each use the distributive property to dete
nasty-shy [4]

Answer:

They can seat <u>520</u> students.

Step-by-step explanation:

Given:

The night school auditorium is able to seat 8 elementary school groups of 65 students each.

Now, use the distributive property to determine the number of students they can seat.

Total number of elementary school groups = 8.

Number of students in each group = 65.

So, using the distributive property to get the number of students they can seat:

  8(65)

=8(60+5)

=8\times 60+8\times 5

=480+40

=520.

Therefore, they can seat 520 students.
