If I have 14 neutrons and 11 electrons, what is my mass number?

A.25
B.3
C.11
D.14

Answers

Answer 1

Answer:

A : 25

Step-by-step explanation:

In a neutral atom, the number of electrons is equal to the number of protons. The atomic number indicates the number of protons.

The mass number is the sum of the number of neutrons and the number of protons.

mass number=protons+neutrons

As we know from the atomic number, the number of neutrons is 14 and the number of electrons is 11.

mass number = 14 + 11

Answer 2
I think the answer is 25

Sean's party will cost $60 if he invites 12 guests. Which expression does NOT equal the amount that Sean will spend per party guest in dollars?

Answers

Options :

A) 12⟌60

B) 60 ÷ 12

C) 60⟌12

Answer:

C) 60⟌12

Step-by-step explanation:

Given that :

Total cost of inviting 12 guests to a party = $60

To obtain the cost per guest :

Total cost of invitation / number of guests

That is ; we divide the cost of inviting the guests by the number of guests invited

$60 / 12 = 12⟌60

The expression 60⟌12 is incorrect as this means 12 / $60

Step-by-step explanation: subtract 6 from both sides to get  2z=1 divide both sides by 2, you get z = 1/2 check by inputting 1/2 for z

2(1/2)+6= 7

1/2 of 2 is 1

1+6=7

it checks out :)

Answer: z= 1/2

explanation:

if 7=2z+6, z would be 1/2, because 2 times 1/2=1. then 6+1 s equal to 7

⅜ or ⅗

Step-by-step explanation:

I say ⅜ because of how many variables you can take into account 3 different colors, and a 2 sided coin, lastly 3 different numbers. So in total that is 8 possible variables and the 3 being blue, heads, and landing on 1.

Now I say ⅗ because of this perspective on the variables. You have the 3 colors, and your two sided coin but thing here is that the 1 is basically another color so the question is technically asking for the probability of spinning blue, landing on heads and landing on red in a sense.
