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

Step-by-step explanation:

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).

Answers

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).

2/5 as a decimal show all work

Answers

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

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.

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.
