Presumably our goal is to show PRQ=SRQ, PQR=SQR and QR=QR for ASA.
A. QR=QR is the reflexive property; things are congruent to themselves, TRUE
B. We need to prove that, but it doesn't have anything to do with the symmetric property.
C. PQ=SQ isn't something we'd need to show for our ASA proof
D. Again, not the symmetric property.
Answer: A
If you rewrite this phrase to be an equation, with N representing the missing number, it would be:
20% x N = 1581.01 or 0.2N = 1581.01
This equation basically says 20% of what number equals 1581.01.
To get to the answer, divide both sides by 0.2. -->
0.2N ÷ 0.2 = 1581.01 ÷ 0.2 -->
N = 1581.01/0.2
N = 7905.05
Answer:
Step-by-step explanation:
Given
--- Initial Amount
every 10 years
Required
The remaining amount after 300 years
To do this, we make use of:
Where
r = decay rate
T = the period of decay
In 300 years, there are 30 periods of 10 years.
i.e.
