An investment of $29,000 was made by a business club. the investment was split into three parts and lasted for one year. the first part of the investment earned 8% interest, the second 6%, and the third 9%. total interest from the investments was $ 2250. the interest from the first investment was 4 times the interest from the second. find the amounts of the three parts of the investment.

The amounts of three parts of the investment are 18000, 6000, 5000 respectively.

Step-by-step explanation:

An investment of $29,000 was made by a business club.

Let the amount of first and second investment be x and y respectively. So, the amount of third investment is (29000-x-y).

The first part of the investment earned 8% interest, the second 6%, and the third 9%. Total interest from the investments was $ 2250.

On simplification we get

                 ..... (1)

The interest from the first investment was 4 times the interest from the second.

                              .... (2)

From (1) and (2) we get

Divide both sides by 0.06.

Put this value in equation (2).

The amount of third investment is

Therefore the amounts of three parts of the investment are 18000, 6000, 5000 respectively.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
