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.
Answer:
Portugal
Step-by-step explanation:
BrazilArea = 8.51 × 10^6 km²Population = 1.99 × 10^8 peopleDensity 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 peopleDensity of population:
1.08 × 10^7 / 9.21 × 10^4 =1.08 × 10^3 / 9.21 =1080 / 9.21 =≈ 117.26 people/km²Portugal has a greater number of people per square kilometer
2/5 as a decimal show all work
Answer:
0.4
Step-by-step explanation:
to convert from a fraction to a decimal, we first have to make the denominator 100
we know that 5 goes into 100 20 times ;
100 ÷ 5 = 20 ;
then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;
[tex]\frac{2}{5}[/tex] [tex](\frac{20}{20})[/tex]
2 x 20 = 40 ;
= [tex]\frac{40}{100}[/tex]
then to convert this into a decimal, divide the numerator by the denominator
40 ÷ 100 = 0.4
|5х + 8| = x what is the correct answer for x and how do you get it?
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.
4x

What percent of 55 is 125?
a. 866.7%
b.2273%
C.2.3%
d. 44%
Answer:
C. 2.3%
Step-by-step explanation:
What percent of 55 is 125 kind of also means how many 55's can go into 125 so you do 125 divided by 55 which is 2.272727.....and so on.
In the answer choices C. 2.3% is the closest.

Answer:
(4,3)
Step-by-step explanation:
To get from the fire pit to the tree, you have to go up 6 and over 6. 1/3 of each of those distances is 2 (6*1/3). So to get 1/3 of the distance, you have to go up to and over 2 from the fire pit. That would land at the point (4,3)

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

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

Nets that will form into a cube
which of the following functions is graphed below?
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.

what is the least common denominator of 8 and 12
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.

M is the midpoint of segment AB and M (-4,-5) and A (-2,-9) find the endpoint B.
(-6, -1) b) (4,-1) c) (-2,4) d) (4,2)
The midpoint of a line segment divides a line segment into two equal parts. (T/F).
Answer:
(-6, -1)
Yes, the midpoint of a line segment divides the segment into two equal parts. True.
Step-by-step explanation:
Going from A(-2, -9) to M(-4, -5), x decreases by two units from -2 to -4; if we now go from M(-4, -5) to B, we expect that x will decrease by two more units, from -4 to -6. Thus, the x-coordinate of B is -6.
y increases by 4 from -9 to -5 (4 units) under the same circumstances. To find the y-coordinate of B, we add 4 to -5, obtaining y = -1.
The endpoint B is thus (-6, -1).
