What is .9 repeating as a fraction

Finger [1]

There is no answer to this because:

Any digit repeating like that would usually be ?/9

Example: 0.1 repeating = 1/9

0.2 repeating = 2/9

0.8 repeating = 8/9

But 0.9 repeating? There should not be a fraction for that.

If you want to round up to 1, you can.

Find the variation constant and an equation of variation for the given situation.

Angelina_Jolie [31]

Answer:

$\displaystyle y=14\cdot x$

Step-by-step explanation:

<u>Directly Proportion</u>

It's said that y varies directly proportional as x, if:

$y=k\cdot x$

Where k is a constant of proportionality.

We know that y=7 when x=1/2.

Using the above condition, we can find the value of k:

$\displaystyle 7=k\cdot \frac{1}{2}$

Solving for k:

k=14

Thus, the equation is:

$\boxed{\displaystyle y=14\cdot x}$

an airplane 30000 feet above the ground begins descending at a rate of 2000 feet per minute. write an equation to model the situ

choli [55]

A = 30,000 - 2000m where A=altitude and m = number of minutes

After 5 minutes A ( altitude) = 30,000 - 2000(5) = 20,000 feet
