Step-by-step explanation:

Brazil has an area of approximately 8.51 x 10^6 square kilometers and
a population of about 1.99 x 10^8 people. Portugal has an area of
approximately 9.21 x 10^4 square kilometers and a population of about
1.08 x 10^7 people. On average, which country has a greater number of
people per square kilometer? Explain how you know.

Answers

Answer:

Portugal

Step-by-step explanation:

BrazilArea = 8.51 × 10^6 km²Population = 1.99 × 10^8 people

Density of population:

1.99 × 10^8 / 8.51 × 10^6 =1.99 × 10^2/8.51 =199/8.51 =≈23.38 people/km²PortugalArea = 9.21 × 10^4 km²Population = 1.08 × 10^7 people

Density of population:

1.08 × 10^7 / 9.21 × 10^4 =1.08 × 10^3 / 9.21 =1080 / 9.21 =≈ 117.26 people/km²

Portugal has a greater number of people per square kilometer

what is the least common denominator of 8 and 12

Answers

Answer:

The least common denominator of 8and 12 is 24

The least common denominator of the numbers 8 and 12 is 4.

The given numbers are 8 and 12.

When two or more fractions have the same denominators, they are termed as the common denominators. The least common denominator (LCD) refers to the smallest number that is a common denominator for a given set of fractions.

Here, the factors of the given numbers are

8 = 2×2×2

12 = 2×2×3

So, the common factor is 2×2=4

Therefore, the least common denominator of 8 and 12 is 4.

Answers

5x+8=x

Step 1: Subtract x from both sides.

5x+8−x=x−x

4x+8=0

Step 2: Subtract 8 from both sides.

4x+8−8=0−8

4x=−8

Step 3: Divide both sides by 4.

find the real numbers x and y that make the equation true (5-2i)-7=x-(3-yi)

Answers

Answer:

x=1 and y=-2

Step-by-step explanation:

5-2i-7=-2-2i

x-(3-yi)=x-3+yi

we write this equation -2 - 2i = (x-3) +yi

so -2=x-3 and -2i=yi

+3 +3 :i :i

1=x -2= y

so x=1 and y= -2

which of the following functions is graphed below?

Answers

Step-by-step explanation:

For y = x^3 - 4 when x = 0, y = -4.

For y = x^2 + 3 when x = 0, y = 3.

Looking at the graph, the y-intercept of the function is below 0. Hence the bottom part is from x^3 - 4 and the top is from x^2 + 3.

The bottom part has a dark circle, which means when x = 1 it belongs to x^3 - 4.

Hence the answer is D.

a. name the vertex of <4 b. Name the sides of <1 c. Write another Name for <5 d. classify each angle

Answers

Answer:

A. vertex B

B. Side BC and BD

C. Angle EBD

Step-by-step explanation:

An angle is an undefined term in plane geometry.

The vertex of [tex]\angle 4[/tex] is BThe sides of [tex]\angle 1[/tex] are BC and BDAnother name for [tex]\angle 5[/tex] is [tex]\angle DBE[/tex].[tex]\angle FBC[/tex] is a right angle[tex]\angle EBF[/tex] is an obtuse angle [tex]\angle ABC[/tex] is a straight angle.[tex]\angle EBC = 144[/tex][tex]\angle ABE =13.5[/tex]

Vertex of [tex]\angle 4[/tex]

The vertex of an angle is the point where the rays that form the angle meet.

From the diagram, rays BE and BA meet at point B to form [tex]\angle 4[/tex].

Hence, the name of the vertex is B

Sides of [tex]\angle 1[/tex]

The sides of an angle are the rays or sides that form the angle

[tex]\angle 1[/tex] is formed by rays BC and BD

Hence, the sides are BC and BD

Another name for [tex]\angle 5[/tex]

An angle can be named by combining the sides and the vertex.

The sides of [tex]\angle 5[/tex] are DB and BE, while the vertex is B

This means that rays DB and BE meet at point B

Hence, another name is [tex]\angle DBE[/tex]

Classify the angles

Angles are classified based on the measure

[tex]\angle FBC[/tex] is a right angle, because [tex]\angle FBC = 90^o[/tex]

[tex]\angle EBF[/tex] is an obtuse angle because [tex]\angle EBF[/tex] is greater than [tex]90^o[/tex] but less than [tex]180^o[/tex]

[tex]\angle ABC[/tex] is a straight angle, because [tex]\angle ABC= 180^o[/tex]

Angle bisector

The line or ray that divides an angle into equal halves is an angle bisector.

Ray BE is an angle bisector, because it divides [tex]\angle DBA[/tex] into two equal halves.

Find [tex]\angle EBC[/tex]

We have:

[tex]\angle EBD = 36[/tex]

[tex]\angle DBC = 108[/tex]

[tex]\angle EBC[/tex] is calculated using:

[tex]\angle EBC = \angle EBD +\angle DBC[/tex]

[tex]\angle EBC = 108+36[/tex]

[tex]\angle EBC = 144[/tex]

Find [tex]\angle ABE[/tex]

We have:

[tex]\angle EBF = 117[/tex]

[tex]\angle DBC = 108[/tex]

[tex]\angle ABE[/tex] is calculated using:

[tex]\angle EBF = \angle ABE +\angle EBD + \angle ABF[/tex]

Where

[tex]\angle ABF = 90[/tex]

[tex]\angle ABE = \angle EBD[/tex]

So, we have:

[tex]117 = \angle ABE +\angle ABE + \angle 90[/tex]

[tex]117 = 2\angle ABE + 90[/tex]

Collect like terms

[tex]2\angle ABE =117 - 90[/tex]

[tex]2\angle ABE =27[/tex]

Divide both sides by 2

[tex]\angle ABE =13.5[/tex]
