Answer: D. About
inches per hour.
Step-by-step explanation:
1. The city received
inches of rain in
hours.
2. Let's write the mixed number as decimal numbers:


3. To find the approximate rainfall rate in inches per hour, you must divide 12.25 inches by 25.5 hours, as following:

4. If you round the result to the nearest tenth, you obtain:

5. Therefore, the answer is the option D.
For this case we must find the inverse of the following function:

We follow the steps below:
Replace f(x) with y:

We exchange the variables:

We solve for "y":

Multiply by -2 on both sides of the equation:

We raise both sides of the equation to the square to eliminate the radical:

We subtract 3 from both sides of the equation:

We change y by f ^ {- 1} (x):

Answer:
This is an arithmetic sequence with first term (a) = 11, number of terms (n) = 57, sum of nth term (Sn) = 19,779.
Let the amount of money she saved more each month be d, then
Sn = n/2(2a + (n - 1)d)
19,779 = 57/2(2(11) + (57 - 1)d)
19,779 = 28.5(22 + 56d)
19,779 = 627 + 1,596d
19,779 - 627 = 1,596d
d = 19,152/1,596 = 12
Therefore, she saved $12.00 more each month.
