Answer:

Around 112.98 or 113.04 (Read step-by-step)

Step-by-step explanation:

37.68^2/4*pi=

If you're using pi is 3.14, the answer is 113.04. But if you're using pi as pi, the entire number, the answer is 112.98.

What is the fraction twelve twentieths in its simplest form
Alla [95]
You mean \frac{12}{20} or \frac{20}{12} ?

If you had meant, \frac{12}{20}, then the simplest form of this fraction would be - \frac{3}{5}

Divide both parts of the fraction by 4, and you get \frac{3}{5}the simplest form of the fraction.
Finding out the simplest form of a given fraction is nothing else than cancelation.

Flop it, you have with you - \frac{20}{12}
Flop the simplest form of the previous fraction, that's \frac{5}{3}

If you had meant \frac{20}{12}, then this will certainly be of any use to you.

HOW TO UNDERSTAND THAT THE FRACTION IS IN ITS SIMPLEST FORM?
Maybe, you are just simplifying and simplifying...but you don't even know when to stop. You can understand whether a fraction is in its simplest form or not by seeing that the numerator and the denominator have a common factor to divide it by, or not.

For instance, consider the case here - \frac{3}{5} or \frac{5}{3}<span>. We can't divide it any further. So, we know that it is in its simplest form.
</span>
L O N G Process:
Well, if you want to divide it by the smallest common factor to its larger, then --
\frac{12}{20} or \frac{20}{12}

1) 
Divided by 2 = \frac{6}{10} or \frac{10}{6}

2) 
Next, also by 2 = \frac{3}{5} or \frac{5}{3}

That took much longer, right.
<span> So, it is more preferable to divide the fraction by the possible largest common factor, you can guess of.</span>

The price of gold has increased by 35% per year from 2000 in the year 2000 hairy bought a gold ring for $590 which of the follow
Lyrx [107]

Since the price is increasing by percentage, rather than a constant rate, we will be using the exponential equation format, which is y=ab^x (a = initial value, b = growth/decay)

Since the value was $590 in the year 2000, 590 will be our a variable.

Since the value is *increasing* by 35%, add 1 and 0.35 (35% in decimal form) together to get 1.35. 1.35 is going to be your b variable.

Putting our equation together, our equation is f(x) = 590(1.35)^x

In 5 OR MORE SENTENCES, write a short story explaining the graph OR write about the key features of the graph.
rewona [7]

The graph illustrated is divided into three seperate sections namely <em>A, B and C,</em> the short story culled from the graph is described thus:

Rate of change or slope = (Rise/ Run)

  • <em>Rise = y2 - y1 </em>
  • <em>Run = x2 - x1 </em>

<u>SECTION A:</u><u> </u>

Slope = (40 - 0) ÷ (20 - 0) = 40/20 = 2

Distance traveled = 50 meters

<u>SECTION B</u> :

This section gives an horizontal line, hence, the slope is 0.

Distance covered = 0 ; as there was no change in the distance over the period of time.

<u>SECTION</u><u> </u><u>C</u><u>:</u>

Slope = (80 - 50) ÷ (70 - 60) = 30/10 = 3

The total distance traveled = 80 - 50 = 30 meters

<u>The total </u><u>distance</u><u> </u><u>and</u><u> </u><u>time spent traveling</u> :

Total distance traveled = (50 + 30) = 80 meters

Total time spent = 70 seconds (<em>time at the 80 meter mark</em>)

Hence, the story.
