Answer:
7.5 sq ft
Step-by-step explanation:
1.5*5=7.5
The design is 1/5 of the actual size, so you just multiply by 5 to get the real size.
Answer:
10 books
Step-by-step explanation:
5 shelves and 45 books on each of those shelves equals 225. 235 minus 225 is equal to 10 books.
Answer:
28.45%
Step-by-step explanation:
The price of a new cell phone = $225
With the extended warranty, the total cost comes to $289.
We need to find the percent of the purchase price is the price of the warranty. It can be calculated as follows :
So, the percent of the purchase price is 28.45%.
7 -3 2/5
= 7 -17/5
= 35/5 -17/5 (common denominator is 5)
= 18/5
= 3 3/5
The final answer is 3 3/5~
The increase indicates a compound growth of 3.2% per year.
The multiplier is given by 100%+3.2% = 103.2% = 1.032
The initial amount of GDP is 577 billion
We are looking to find in how many years since 1985 that the GDP equals to 1.6 trillion, this is 1.6×10³ billion
The formula for a compound growth/decay is given as
, where
is the final value and
is the intial value.
We are looking to find 'n'
1.6×10³ = 577(1.032)ⁿ
(1.6×10³) ÷ 577 = 1.032ⁿ
1060/577 = 1.032ⁿ ⇒ take log both sides
log( 1060/577 ) = log (1.032)ⁿ
log (1060/577) ÷ log (1.032) = n
n = 19.31 ≈ 19 years
The year when GDP achieves 1.6 trillion is 19 years from 1985, which will be in 2004, providing the increase rates stays the same.
