Answer:
The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
Step-by-step explanation:
Cost of building 20 years ago = 12000000
We are given that the cost depreciated at 9% per year
Formula : 
Where N(t)= Population after t years
=Initial population=12000000
r= rate of depreciation=0.09
t = 20 years
Substitute the values in the formula:

N(t)=1819738.95
Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

Answer:
Her estimate is reasonable.She can make 25 completed centerpieces
Step-by-step explanation:
Estimate 20 flowers per centerpiece. 430 flowers divided by 20 flowers per centerpiece.
430 /20 is approximately 21 centerpieces. Her estimate is reasonable.
430/20 Divide the top and bottom by 10
43/2 is 21*2 = 42 with 1 left over 21 1/2
We know we underestimated when we rounded 17 to 20. Se we are a little under with 21.5
Exact answer:
430÷17
17 goes into 43 2 times (17*2 = 34 43-34 = 9 left over)
17 goes into 90 5 time (17*5 = 85 90-85 = 5 left over)
She can make 25 completed center pieces
Answer is 4 because 1x4 =4 , 2x4= 8 ... and so on because that is the really thing that only makes sense
