Why does pi to trillions of places still not have a precisely even distribution of each digit?

Here’s some information about what Pi (π) is:

<u>Intro</u>

Pi (π) is a number whose decimal digits go on forever and they don’t repeat itself. It’s in the category called irrational numbers, because you can’t rationalize pi.

<u>History</u>

Before pi was created, famous philosophers used tape measure to measure the ratio between the circumference and diameter of a circle. And when they did, they found out that the ratio between the circumference and diameter was roughly about 3.1. But as mankind evolved to have better tape measures and more technology they can use, they found out that the ratio between the circumference and diameter had a number that kept on going forever. It would go like 3.1415926.... and it would go on and on. So, the number pi was introduced by scientists and mathematicians found out that pi turned out to be an irrational number.

<u>Daily Usage</u>

Pi was turned into the symbol π so people don’t have to write the full digits of pi. But now we use pi now in our daily mathematical lives. Pi is almost in every form of mathematics, especially in geometry and trigonometry. Pi is full of new things and it really expanded our understanding of mathematics.

<em>Pi (π) truly has an interesting and fascinating history</em>

Hope this helps! :)

A man bought 20 dozens of eggs at 90.00 Ghana cedies a dozen and sold them at 1.20 Ghana cedies a dozen. Find his gain percent​
Anuta_ua [19.1K]

Answer:

33.33%

Step-by-step explanation:

Given that CP for 20dozen = 20×90

= 1800

SP = 20×120

= 2400

Gain % = (Gain / CP) ×100

Gain = SP-CP

So is the selling price

Cp is the cost price

Hence Gain = 2400-1800

Gain = 600

Gain% = 600/1800 ×100/1

= 0.333×100/1

= 33.33%

Hence his percentage gain will be 33.33%

Since the question stated that percentage gain is to be calculated, I believe the sell price should be higher than the cost price. Hence 1.20 Cedis would not work so I used 120 Cedis instead. Thanks

Vika [28.1K]
Convert to vertex form:- 
= -0.04(x^2 + 39x)
= -0.04( (x + 19.5)^2 - 380.25)

vertex is at -0.04 * -380.25 = 15.21 yards

Maximum height is about 15.2 yards

The perimeter of a triangle is 93 ft. Side a of the triangle is twice as long as side b. Side c is 3 ft longer than side a. Find
Sunny_sXe [5.5K]

The length of side a is 36 feet and side b is 18 feet and side c is 39 feet

<em><u>Solution:</u></em>

Given that perimeter of triangle is 93 feet

The three sides of triangle are a, b, and c

<em><u>Given that Side a of the triangle is twice as long as side b</u></em>

side a = 2 times side b

a = 2b

b = \frac{a}{2}  ---- eqn 1

<em><u>Given that Side c is 3 ft longer than side a</u></em>

side c = 3 + side a

c = 3 + a ------ eqn 2

<em><u>The perimeter of triangle is given as:</u></em>

p = a + b + c

Where a, b, c are the length of sides of triangle

Substitute eqn 1 and eqn 2 in above formula

p = a + \frac{a}{2} + 3 + a

Given that perimeter = 93

93 = a + \frac{a}{2} + 3 + a\\\\93 = \frac{2a + a + 6 + 2a}{2}\\\\93 \times 2 = 2a + a + 6 + 2a\\\\186 = 5a + 6\\\\5a = 186 - 6\\\\5a = 180\\\\a = 36

Thus length of side a = 36 feet

<em><u>Length of side b :</u></em>

from eqn 1

b = \frac{36}{2} = 18

b = 18 feet

<em><u>Length of side c:</u></em>

From eqn 2,

c = 3 + 36 = 39

c = 39 feet

Thus length of side a is 36 feet and side b is 18 feet and side c is 39 feet

A rectangle has a length of 9.00 inches and a width of 4.25 inches. What is the area in square inches? Round to the correct sign
Gwar [14]
Both numbers (9.00 and 4.25) have three sig-figs. This means that the final answer will have three sig-figs as well.

Multiply the numbers to get: 9.00*4.25 = 38.25 which rounds to 38.3 because the answer must have three sig-figs. 

The units will be "square inches" or "inches^2" or "in^2". There are various ways to write the units portion.

Overall, the final answer is 38.3 square inches.

High school geometry
san4es73 [151]

Answer:

BD = 3.75 units

Step-by-step explanation:

Given AD is an angle bisector then it divides the opposite side into segments tat are proportional to the other 2 sides, that is

\frac{AB}{AC} = \frac{BD}{CD} , substitute values

\frac{6}{8} = \frac{BD}{5} ( cross- multiply )

8 BD = 30 ( divide both sides by 8 )

BD = 3.75 units
