What will be the price of gas if there is a 27% increase from $2.67 per gallon?​
Rufina [12.5K]

Answer:

The answer is $3.39

Step-by-step explanation:

the question states an increase in price. this means that we need to multiply the current prince ($2.67) by 127%.

drop the percent and put 127 over 100

\frac{127}{100}

multiply

\frac{127}{100} *\frac{2.67}{1}\\\\ \frac{339.09}{100} \\\\3.39

we are dealing with currency so rounding to the hundredths place will suffice.

hope this helps :)

Where in the bible is there an indication of the value of pi what was the approximate value?
Morgarella [4.7K]
The Bible, a book that is considered the perfect word of a perfect god tells us what the value of Pi is. Let's see verse 1 Kings 7:23
 He also melted a sea of ​​ten cubits from one side to the other, perfectly round; Its height was five cubits, and a cord of thirty cubits encircled it.

 These are a list of specifications for the great temple of King Solomon, built about 950 BCE, and his interest here is that it gives a value of π = 3. If we divide 30 cubits between 10 cubits (which are the measures mentioned in written radical) gives us exactly 3.

 We know that the length of the circumference is calculated l = 2 · π · r; Since 2 · r is the diameter, it can also be said that

 circumference = diameter × π

 If we go back to what the Bible says, the diameter is 5 meters and the circumference of 15:

 circumference = diameter × π -> 15 = 5 × π

 with which the value of π is 3.

 This calculation of Pi is a bad approximation to the real value. The figure of 3 in the Bible compared with the real one which is 3.1416 ... indicates an error of about 6%.
