If you earned $240 interest on a loan of $600 at an interest rate of 5%, how many years was the loan for?

Answers

Answer:

The loan was for 8 years.

Step-by-step explanation:

It is stated that you earned $240 interest on a loan of $600 at an interest rate of 5%.

Find the duration time by using the formula

I = Pit

Here:

'I' is the interest'P' is the total principal loan'i' is the rate of interest per year't' is the total time in years

substituting I = $240, P = $600 and i = 5%

I = Pit

t = I / Pi

 = 240 / (0.05 × 600)

 = 240 / 30

t = 8 years

Therefore, the loan was for 8 years.

Step-by-step explanation:

4(f-3)=20     distribute

4f-12=20      add

4f-12+12=20+12... 4f=32   divide

4f/4=20/4..... f=5

Answer:

F=8

Step-by-step explanation:

DIVIDE BOTH SIDES BY 4

4(f-3)=20     Dividing 4(f-3) by 4 cancels out the 4 leaving it f-3

true or false: to find the second derivative of a function take the derivative of the furst derivative if the function

Answers

Answer:

True

Step-by-step explanation:

The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).

Additionally, most must also graduate from their agencys training academy and fulfill difficult personal and physical qualifications, as well. In 2010, police officers in the United States earned a median yearly income of approximately $55,000. Unfortunately, there is a high rate of on-the-job injuries for police officers.A judge is responsible for applying the law in court and overseeing the legal process. One of the major duties of a judge is to help negotiate agreements between opposing parties. Most judges are elected or appointed, and they are typically required to have a law degree and to have worked as a lawyer. The average median yearly salary for judges in 2010 was $92,000.Both of these careers are a part of the legal system. Similarly, both require specialized training before a job can be obtained. However, it takes much longer to become a judge than it does a police officer, and a judge can expect to make more money. Although they are both trained to uphold the law, the role each plays in the legal system is very different.What does the signal word Similarly tell the reader in the third paragraph?Judges and police officers both play roles in the legal system.Police officers and judges earn similar yearly wages and benefits.It takes the same amount of time to become a police officer and a judge.It takes specialized training to become both a police officer and a judge.
