3. Bob the Builder wants to earn an annual rate of 10% on his investments, how much (to the
nearest cent) should he pay for a note that will be worth $3,000 in 9 months?

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

In this question:

Rate of 10%, so I = 0.1.

9 months, so

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

Then

He should pay $2,790.7.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
