Anita invested $6000, some at 5% and the rest at 6%. If the yearly income is $337.50, what is the amount invested at each rate?
Pepsi [2]

Let the amount invested with 5% interest be x

Therefore, the amount invested with 6% interest will be (6000-x)

It is given that the total interest earned yearly is $337.5. Thus, the equation of interest will be:

\frac{5}{100}x+\frac{6}{100}(6000-x)=337.5

Multiplying both sides by 100 we get:

5x+6(6000-x)=33750

5x+36000-6x=33750

Subtracting both sides by 36000 we get:

-x=-2250

\therefore x=2250

Thus, the amount invested at 5% is $2250

Therefore, the amount invested at 6% will be $(6000-2250)=$3750

A group of hikers buys 8 bags of mixed nuts. Each bag contains 3 1/2 cups of nixed nuts. The mixed nuts are shared evenly among
aalyn [17]
<h2>Greetings!</h2>

Answer:

Each hiker gets \frac{7}{3}  cups of mixed nuts.

Step-by-step explanation:

First, we need to find the total amount of cups by multiplying the number of bags with the amount of cups in each bag:

8 * 3.5 = 28

Now, we divide this by 12 to find the amount of cups per hiker:

28 ÷ 12 = \frac{7}{3} or 2.3333

So each hiker gets  \frac{7}{3}  cups of mixed nuts.

The arithmetic mean (A) of two numbers (a and b) is given by the formula A=a+b/2, and their geometric mean (G) is given by G=√ab
Ann [662]
A = a+b / 2
G = √( a b )
G = √ ( A H )   / ²  ( we will square both sides of the equation )
G² = A H
H = G² / 2
H =  \frac{G ^{2} }{A}= \frac{a b}{A}= \\ = \frac{ab}{ \frac{a+b}{2} }= \frac{2ab}{a+b}
