Answer: 1/10
Step-by-step explanation:
At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.
Sum of inside angles of a polygon= 180º(n-2)
n=number of sides.
This polygon has 6 sides, the sum of all its angles would be=180º(6-2)=720
let´s:
xº=inside angle
xº=720º-sum of the others inside angles.
xº=720º-(75º+130º+120º+105º+145º)=720º-575º=145º
yº=180º-xº=180º-145º=35º
Answer: yº=35º
438+382

Final Answer: 820
Question 1
Pv=pmt [(1-(1+I)^(-n))÷I]
Pv=256×((1−(1+0.021)^(−29))÷(0.021))
pv=5,518.198
Question 2
PMT=pv÷[(1-(1+I)^(-n))÷I]
PMT=19,621÷((1−(1+0.023)^(
−77))÷(0.023))
=546.09
Question 3
N=log ((1-((pv×I)÷pmt))^(-1))÷log (1+I)
N=log((1−(14,000×0.015)
÷450)^(−1))÷log(1+0.015)
=42.22years
