Ratinonal numbers can repeat as long we can see the repeating part with a line over it (called a vinculum)
rational numbers can be written in form a/b where b is not equal zero

1.33333333333333 is repeating, it is 4/3

3.1415... is obviously an attempt to represent pi or π, the most famous irrational number

5.25 is easy, 5.25/1 or 525/100

0.6666666666666=2/3

the answer is 3.141592...

Ad libitum [116K]

Answer:

depending on what your using these are the answers to what I got:

Addition: 2 1/2

Multiplication: 135/256

Division: 2 2/5

Step-by-step explanation:

1 1/8 + 3/4 + 5/8 = 5 /2 = 2 1/2 = 2.5

1 1/8 x 3/4 x 5/8 = 135/256 = 0.527

1 1/8 ÷ 3/4 ÷ 5/8 = 12/5 = 2 2/5 = 2.4

Euler Bank advertises that it compounds interest continuously and that it will double your money in 20 yr. What is the annual in

Romashka [77]

To solve this problem you must apply the proccedure shown below:

1. You must apply the following formula:

$FV=(PV)(e^{it})$

Where $FV$ is the future value, $PV$ is the present value, $i$ is the interest rate and $t$ is the time in years.

2. You have that the bank will double your money in $20$ years. Therefore:

$FV=2PV$

3. Substitute values into the formula and solve for $i$ , as following:

$2PV=(PV)(e^{(i)(20)} \\ 2=e^{(i)(20)}$

4. By applying natural logarithm, you have:

$ln(2)=(i)(20) \\ i= \frac{ln(2)}{20} \\ i=0.0346$

$i=3.46$ %

The answer is: $3.46$ %
