Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn) have a completely filled outer electron shell and are therefore called inert gases. What do the inert gases have in common?

1.They behave similarly in chemical reactions
2.They have the same number of protons
3.They have the same number of electrons
4.They belong to the same period

Answers

Answer 1

Answer:

The answer would be 1.

Answer 2

Answer:

They behave similarly in chemical reactions

Step-by-step explanation:

Because their atomic numbers are different, the elements each have a different number of protons and electrons. They belong to the same group, not the same period.

Ariana needs to rent a car while on vacation. The rental company charges $18.95, plus 16 cents for each mile driven. If Ariana only has $40 to spend on the car rental, what is the maximum number of miles she can drive?

Ariana can drive a maximum of
miles without the cost of the rental going over $40.Round your answer to the nearest mile.

Answers

Answer:

Ok simple Algebra Question:

Let "x" be the number of miles she drives.

18.95 + 0.16x = 40.00

Subtract 18.95 from both sides.

0.16x = 21.05

Divide both sides by 0.16

You get:

x = 131.5625

Round to nearest mile:

Answer is: 132

at the beginning of the basketball game Sabrina made nine points in four minutes she wants to break the school record of 119 points in a game but the game last for 60 minutes in a Sabrina continues to score points at this rate will she break the school record show how you know set up a proportion

Answers

Yes she will break the school record if she continues to score at that rate. You divide 60 / 4 since there are 60 minutes in a full game. That gives you 15. Then you multiply that answer by 9 because she scores 9 points each of those 4 minutes. That will get her to score 135 points by the end of the game

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

 [tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

Substituting the values of the coordinates in the distance formula;

 D = [tex]\sqrt{(1-1)^{2}+(18+4)^{2} }[/tex]

     =[tex]\sqrt{(0)^{2} + (22)^{2} }[/tex]

     = [tex]\sqrt[n]{484}[/tex]

      = 22

So, 22 units is the right answer.

x=(-2),y=(-4)

and in components form,

(-2,-4)

Step-by-step explanation:

equation1 (-2x+2y=-4)

equation2 (3x+3y=-18)

(times equation 1 by 3 and times equation 2 by 2, to make the y values equal to each other)

E1 (-6x+6y=-12)

E2 (6x+6y=-36)

(subtract both equations from each other)

-6x+6y=-12

-

6x+6y=-36

=(-12x=24)

so, x=24÷-12=-2

(then we sub the value of x into one of the equations- the new one or the old one)

y=-12÷3=-4
