where A=final amount
P=principal
r=rate in decimal form
t=time in years
we are given that P=500, r=12%=0.12
we want to find A when t=10, 20, and 30
so


when t=10, 
when t=20, 
when t=30, 
Answer: The answer to complete the sentence should be D).
Which of the following can be used to prove that triangle EFG is also a right triangle?
D. Prove that KL is equal to c by the Pythagorean Theorem
Since we know that both triangles have a and b in common, the same side lengths, then KL must be equal to c as well. Using the Pythagorean Theorem, this can be proved. And because the Pythagorean Theorem can only be used on a right triangle, then triangle EFG must also be a right triangle if KL if also equal to c.
Hope this helps!! :)
Answer:
About 2,800 hours of sleep per year
Step-by-step explanation:
Sleep per day= 7 hours 45 minutes
7 hours 45 minutes=465 minutes
Sleep per day =465 minutes
Sleep per year=365 days × 465 minutes
=169,725 minutes
There are 60 minutes in one hour
Divide 169,725 by 60 minutes
We have,
169,725/60
=2828.7500000 hours
Total sleep in a year is about 2,800 hours
