Answer:
idk
Step-by-step explanation:
The formula is Interest = principle times rate times time in years.
I=prt
p=1000
r= 0.025
t=x
To find the amount of interest that is earned in a specific time frame, subtract the final amount of money by the principal. 1500-1000=500.
500 = 1000(0.025)x
500 = 25x
x= 20 years
Its 0.20 i think bc its the one that make the most since
Answer:
60.2 m
Step-by-step explanation:
Let x represent the width of the river. The distance from the point across from the tree to the second point is 15 m. The angle from this point to the tree across the river is 76°.
This makes the side opposite the angle x, the width of the river. It also means the 15 m side is adjacent to this angle.
The ratio opposite/adjacent is the ratio for tangent; this gives us the equation
x/15 = tan(76)
Multiply both sides by 15:
15(x/15) = 15(tan(76))
x = 15(tan(76)) ≈ 60.2
20096m.
Since the radius is 80, the formula is x²×3.14.
80²=6400
6400×3.14=20096
m is the unit
Answer: 20096 meters
