Hello! For these kinds of problems, the formula for finding the principal is I / rt. That means, divide the simple interest by the rate and time (rate should be in decimal form). In order to find simple interest, just do prt, which means multiply the principal (initial amount) by the rate (simple interest rate, in decimal form) by the amount of time (could be in months or years). With that being said, if you solve it correctly, here are your answers:

Principal: $14,181
Interest rate: 10%
Time: 4 years
Simple Interest: $5,672.40

Principal: $83,079
Interest rate: 9%
Time: 2 years
Simple Interest: $14,954.22

Principal: $659,379.96
Interest rate: 11.7%
Time: 28 months
Simple Interest: $179,753.57

Principal: $18,936
Interest Rate: 2.41%
Time: 3 Months
Simple Interest: $114.09

Note: If the time is in months, be sure to convert it into a decimal and multiply. If a decimal repeats, just convert it to the nearest hundredth.

A person stands 15 ft from an elephant. Determine how tall the elephant is in feet, the given diagram.
Leno4ka [110]

Answer:

The height of the elephant is \dfrac{15}{\sqrt3}\ ft.      

Step-by-step explanation:

It is given that,

Distance between a person and an elephant is 15 ft

The angle of elevation of the elephant is 30 degrees.

We need to find the height of the elephant. For this let us consider that height is h. So,

\tan\theta=\dfrac{P}{B}\\\\\tan(30)=\dfrac{h}{15}\\\\h=15\times \tan(30)\\\\h=\dfrac{15}{\sqrt3}\ ft

So, the height of the elephant is \dfrac{15}{\sqrt3}\ ft.
