What is 2.31 repeating as a simplified fraction

Mathematics
1 answer:
Rudiy274 years ago
4 0

Answer:

2\frac{31}{99}

Step-by-step explanation:

I am assuming that '.31' is the repeating pattern.

<h3>Setting up equation one:</h3>

X=2.31313131....

<h3>Setting up equation two:</h3>

There are two digits in the repeating group. I multiplied the first equation my 100 to get:

100x=231.31...

Subtract equation one from equation two:

'100x-231.3131..' - 'x = 2.313131... ' = '99x = 229'

Solve for X:

99x=299\\\\99x/99=229/99\\\\\boxed{x=229/99}

\frac{229}{99}=2\frac{31}{99}

Write the sum of 7√28x⁶+4√7x⁶ in simplest form, if x≠0​
riadik2000 [5.3K]

Answer:

18√7x⁶

Step-by-step explanation:

Given the expression 7√28x⁶+4√7x⁶, we are to fund the sum in its simplest form as shown;

7√28x⁶+4√7x⁶

= 7√(7*4)x⁶+4√7x⁶

= 7*2√7x⁶+4√7x⁶

= 14√7x⁶+4√7x⁶

Factor out the like term

= 2√7x⁶(7+2)

= 2√7x⁶(9)

= 18√7x⁶

Hence the sum is equivalent to 18√7x⁶

Elena-2011 [213]

Answer:

74.6018 Miles per hour

Step-by-step explanation:

Step 1: How many seconds are in an hour? There are 60 seconds in a minute and 60 minutes in an hour, so there are 60*60 = 3600 seconds in an hour.

Step 2: How many feet are in a mile? There are 5280 feet in a mile.

Step 3: To convert feet per second to miles per hour, first multiply by 3600, then divide by 5280. The fraction 3600/5280 reduces to 15/22.

To convert feet per second to miles per hour, multiply by 15/22.

So: 109.416 feet/second * (15/22) = 74.6018 miles/hour

Effectus [21]

Answer:

  • It has taken Jake about 40 minutes to finish his Spanish homework.

Step-by-step explanation:

<u>We know that:</u>

  • Homework = 4 hours = Spanish + Math + Science + History
  • Spanish = 4 hours x 1/6
  • Math = 4 hours x 1/4
  • Science = 4 hours x 1/4
  • History = 4 hours x 1/3

<u>Work:</u>

  • Spanish = 4 hours x 1/6
  • => 2 hours x 1/3
  • => 2/3 hour
  • => 2/3 x 60 minutes
  • => 40 minutes

Hence, it has taken Jake about 40 minutes to finish his Spanish homework.
