Answer:
Irrational
Step-by-step explanation:
Square root if 12 is 3.464 and the square root of 3 is 1.732. You multiply 3.464 and 1.732 to get 5.99 which would be 6 if you round it up. The reason to why it's irrational is because 6 can not be written as a ratio of two integers, which means it cannot be expressed as a fraction.
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3
n^-6 * n^3 = n^-3
If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.
n^-3 = n^-3 / 1 = 1/n^3
when the factor moves to the other side of the fraction, the side of the exponent changes.
The original price is $30 because 40% off of 12 = 30
Answer:
68
Step-by-step explanation:
speed = distance/time
distance = 391 miles
time = 5 h + 45 m = 5.75 h
speed = (391 miles)/(5.75 h)
speed = 68 miles/hour
Answer: In 1 hour, it travels 68 miles.
