Answer: Rational number

Step-by-step explanation:

A rational number is a ratio of whole numbers.

1/3 is the ratio of 1:3, 3:1 becomes 3/1 = 3, 32:10 can be written 32/10 or 16/5 or 3.2, 16/5 is a rational number 16 and 5 are integers, 5 is not equal to 0.

Therefore, 3.2 which can be expressed as 16/5 is a rational number.

This is why 1.32 is rational.

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.

Fed [463]

Answer:

x = 12, y=7

x=30, y=25

x=15, y=10

Step-by-step explanation:

We have :  y = x - 5

x = 12  then y = 7,     y = 12 - 5 = 7

x = 30     25 = x - 5,   x = 25 + 5 = 30

x = 15,  y = 15 - 5 = 10,  y = 10

Find the area of the polygon.
mart [117]
11x3= 33
3x3=9x2=18
The area would be 51 because you can cut off the two squares making the sides be 3by3 then the rectangle would be 3by11. And you would do HxL. So the area is 51cm

An airport shuttle service charges $15 plus $1.15 per mile. An equation is written as y=mx+b, where y is the cost for x miles.
Free_Kalibri [48]

Answer: See explanation

Step-by-step explanation:

You didn't really say what you need to calculate but let me try to help out.

From the question, we are informed that an airport shuttle service charges $15 plus $1.15 per mile and that an equation is written as y=mx+b, where y is the cost for x miles.

The equation can be expressed as:

y = 15 + 1.15x

where,

15 = y intercept and this is the initial fixed cost

1.15 = slope and this is the cost per mile

x = number of miles
