You are NOT using scientific notation correctly. When you say 22^4 you are saying 22*22*22*22 which equals 234,256. What you should say is Earth to Moon distance = 22 * 10^4 miles. (To be really precise, it should be expressed as 2.2 * 10^5 miles).
Earth to Neptune distance = 2.2 * 10^8 miles.
2.2 * 10^8 / 2.2 * 10^5 = 1,000. So the Earth to Neptune distance is 1,000 times greater than the Earth to Moon distance.
ten less than the cube of a number n:
Answer:
A. Her expenses are $25 per week.
Step-by-step explanation:
Using a linear function f(x) = mx + b, m= slope and b = y-intercept or initial value. With the values of the given function: E(x) = 7x - 25, we can determine that the overall earnings (E(x)) is based on a profit of $7 per door ('x') and that if Jessica is subtracting $25 from her earnings, that this must be the cost per week for her expenses. So, she would need to knock on a minimum of 4 doors each week in order to make a profit.
32.89 should be the answer if I’m reading your question right
The given function is
Here 
represents the number of rows.
represents the total number of seats in the auditorium.
Now the total seats in the auditorium are 416.
So 
Dividing all terms by 2 we get
Subtracting 208 from both sides
Factoring we get
(x-16)(x+13)=0
Using Zero product rule
x - 16= 0 or x+13=0
x= 16 or x = -13
But as x cannot be negative
So x = 16
There are 16 rows in the auditorium if it has a total of 416 seats.
