if 30 parts = 2 gallons
therefore 15 parts = 1 gallon
49-29 = 20
20 - 15 (aka 1 part) = 5
5/15 = 1/3
Final answer:
To adjust the gasoline to oil ratio to 49:1 in a 2 gallon mixture, the forester must add approximately 1.333 gallons of gasoline.
Explanation:
Given that there is a mixture of 2 gallons that is constituted of 29 parts of gasoline and 1 part of oil, it translates into a 30 parts mixture (29 parts gasoline + 1 part oil). In a single gallon of mixture, there are 29/30 gallons of gasoline and 1/30 gallon of oil.
When additional gasoline is added, the amount of oil in the mixture remains constant at 1/30 gallon per gallon while the amount of gasoline increases. To hit a ratio of 49 parts gasoline to 1 part oil, there should be 49 times more gasoline than oil. Since we know the amount of oil in a mixture is 1/30, the amount of gasoline added per gallon should be 49/30 gallons.
However, we start with 29/30 gallons of gasoline, therefore extra gasoline that will be needed per gallon is (49/30) - (29/30) = 20/30 = 2/3 gallons. Given that the mixture is 2 gallons, the forester should add 2/3*2 = 4/3 gallons or approximately 1.333 gallons of gasoline.

Final answer:
To calculate 27 raised to the power of 2/3, you first find the cube root of 27, which is 3 and then square that result, giving you 9.
Explanation:
The question requires the computation of a number, specifically 27, raised to a fractional exponent, which is 2/3. To calculate 27 raised to the power of 2/3, you can break it into two steps: take the cube root of 27 first, and then square the result. The cube root of 27 is 3, because 3*3*3 equals 27.
Then, squaring 3 (i.e., raising 3 to the second power) gives 9. Consequently, 27 raised to the power of 2/3 equals 9. This is a typical problem when dealing with powers and roots in mathematics and demonstrates the application of fractional exponents.
