Answer 1

Which of the following situations describe quantities that combine to make 0?

A carbon 12 atom has six neutrons, six protons, and six electrons. The neutrons have no charge, each proton has a positive charge, and each electron has a negative charge of the same magnitude.

To start the second half of the basketball game, the Eagles made a jump shot for two points. The Bulldogs then took the ball down the court on a fast break and made a layup for two points.

During the top of the fourth inning of a baseball game, the Ravens scored three runs. During the bottom of the fourth inning, the Raiders scored five runs to tie the game.

Answer 2

You can say a b c or d

Answer 3

I want to learn I was just saying when you help with the answer

Answer 4

Well, since protons have a positive charge, they're like positive numbers. Like 4, 54, 23847, and 10. Electrons have a negative charge. They're your negative numbers. Neutrons have no charge. They're the number 0. So let's look at A.

The carbon atom has 6 neutrons. That's 0+0+0+0+0+0. We still get 0. SO we get to ignore those numbers :). Moving on to protons. There's 6 of them and they have a positive charge. That's like adding 6+6+6+6+6+6. Or \[6\times6\] What do you get when you multiply that?

Answer 5

yes i do

Answer 6

What number do you get when you multiply \[6\times6\]

Answer 7

36

Answer 8

Yep, so now we have to move onto the electrons. They have a negative charge and we have 6 of them. When you add \[(-6)+(-6)+(-6)+(-6)+(-6)+(-6)\]What do you get?

Answer 9

Here's a scientific calculator if you don't have one.

Answer 10

-36

Answer 11

Yep. So now when you add \[36+(-36)\]What do you get?

Answer 12

0

Answer 13

Yep, so that's an answer. Do you have to choose more than one answer for this?

Answer 14

yes

Answer 15

Ok, so now we can move onto b. Just a second.

Answer 16

ok:)

Answer 17

Ok. so one team made two points another team made two points also. They evened up the scores.

Answer 18

What do you think about that one?

Answer 19

2+2

Answer 20

Not quite. The first team made 2 points, and the other team made two points to counteract the first two points. It's kind of like adding \[2+(-2)\]

Answer 21

0

Answer 22

Right, so this far, A and B are answers.

Answer 23

Now onto C. If they tied up the game, could C also be an answer?

Answer 24

ok

Answer 25

ummmmm

Answer 26

no?

Answer 27

sorry i have to go bye

Answer 28

thank you for all the help

Answer 29

Lets say that the Ravens started out with 2 runs and the Raiders have 0. The Ravens gained 3 runs. Now they have 5. In the next inning, the Raiders gained 5 runs. They have 5, too. The Raiders just counteracted what the Ravens did.

Answer 30

That's ok. Thanks for letting me help you :)
