tester [92]

Hello there!

Answer: ⇒ C. -30

_________________________________________________________

Step-by-step explanation:

First you had to remove parenthesis.

-7*4-|-6|+|4|

Then you multiply by the number.

=-28-|-6|+|4|

Apply absolute value.

|-6|=6

=-28-6+|4|

Again apply absolute value.

|4|=4

=-28-6+4

Simplify it's should be the correct answer.

=-30

What is the distance to the earth's horizon from
shepuryov [24]

Answer:   216.2 miles

Step-by-step explanation:

Alright, lets get started.

As the diagram shows, the line from point P is tangent to earth's curvature.

It means it is making right angle.

So the triangle formed will be  right triangle.

Hence we can use Pythagorean theorem in it.

So from point P to center of earth, it will be hypotenuse of triangle.

c^2=a^2+b^2

(3959+5.9)^2=3959^2+x^2

3964.9^2=3959^2+x^2

15720432.01=15673681+x^2

x^2=46751.01

taking square root, the x will be :

x = 216.2

hence the value of x is 216.2 miles.   :   Answer

Hope it will help :)
