Givens

Male  =      138,053,563

Female =   143,368,343

Total

The total equals 281 421 906

Percents

Male = (138,053,563 / 281 421 906) * 100 = 49.1%

Female = ( 143,368,343/ 281 421 906) * 100 =  50.94%

Rounded

Male =  49

Female = 51

Comment.

To find this %s you could just use the first 3 digits of everything.

Total = 138 + 143 = 281

% male = (138/281) = 49.1

% female = (143/281) * 100 = 50.88

These give you the same answers when rounding.

What is the equation for the line that passes through the points (-2,1) and (1,-11)
givi [52]

Answer:

y=4x+7

Step-by-step

(-2,1) and (1,-11)

1)Rule you should use is run over rise aka slope

y²-y^1=

x^2-x^1=

(-11)-1=12

1-(-2)=3

12/3=4

slope =4

2)Rule of point slope intercept

y - y1 = m(x - x1)

y+1=4(x+2)

y+1=4x+8

   -1     -1

y=4x+7

The Eiffel Tower in Paris, France. Lizbeth is 5.5 feet tall. She looks up at an angle of elevation of 72° to see the top from 31
garri49 [273]

Answer:

The height of the Eiffel Tower will be 318 feet.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that Lizbeth is 5.5 ft tall, seeing the top from 318 feet away, making an angle of elevation to be 72⁰.

The diagram makes a right-angled triangle.

  • Given the angle = Ф = 72⁰
  • Adjacent = a = 5.5 ft
  • Opposite = b = 318 ft
  • Hypotenuse = the height of the Eiffel Tower = c ?

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

c=\sqrt{a^2+b^2}

  • a=5.5
  • b=318

c=\sqrt{5.5^2+318^2}

c=318 feet

Therefore, the height of the Eiffel Tower will be 318 feet.

What is the population density of the US if the area of the United States is 4,000 square miles?
scoray [572]

Answer:

82050 people/mi^2

Step-by-step explanation:

The population of the US is 328.2 million people and the area of the US is 4000 mi^2 as given. The population density is found by (population)/(area), so we input our values in:

Population density = 328, 200, 000/4000 = 82050 people/mi^2

I hope this helps! :)
