85 gallons per day is the unit rate. divide 2550 by 30
To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:
"d" represents the distance and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is 12,6 u.c.
Is 16 an option because if it is then... it's right?
Answer:
1) A
2) B
Step-by-step explanation:
For this problem we use exponential growth formulas
if the population increases when t increases
If the population decreases when t increases
Where and is the population as a function of time, 
is the initial population, r is the growth rate, t is the time in years.
1) In this situation we have that 
, the growth is 2.4%, then 
and 
and the equation is:
-------- Option A)
2) In this situation we have that 
, the decrease is 1.7%, then 
and 
and the equation is:
-------- Option B)
A: For the Dentist, their average income in 30 years is $4,282,200
B: For the Manager, their average income in 30 years is $2,592,000
C: The difference in both their earnings is $1,690,200
Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.
I hope this helps you. :)
