  1. write the following number in scientific notation. 26,496
  2. by tradition, horse races are measured in furlongs. a furlong is $\frac{1}{8}$ of a mile. how long is a 5 - furlong race in miles?

  1. a commercial jet flies from st. louis, missouri, to buenos aires, argentina, a distance of 4,707 nautical miles. if the plane flies at 210 knots, how long will the trip take? (a knot is 1 nautical mile per hour.)

Explanation:

Mon - Problem I

Step1: Recall number - type definitions

A real number is any number on the number line. A rational number can be written as a fraction $\frac{p}{q}$ where $p,q$ are integers and $q
eq0$. $\pi = 3.14159\cdots$ is non - repeating and non - terminating.
Since $\pi$ is a non - repeating, non - terminating decimal, it is a real number but not a rational number. It is an irrational number.

Step1: Recall scientific notation form

Scientific notation is $a\times10^{n}$, where $1\leq|a|\lt10$ and $n$ is an integer.

Step2: Rewrite the number

For $26496$, move the decimal point 4 places to the left to get $a = 2.6496$ and $n=4$. So, $26496=2.6496\times 10^{4}$

Step1: Set up the proportion

If 1 furlong is $\frac{1}{8}$ of a mile, and we want to find out how many miles is a 5 - furlong race. Let $x$ be the number of miles in a 5 - furlong race. Then the proportion is $\frac{1}{8}=\frac{x}{5}$.

Step2: Solve for $x$

Cross - multiply: $x=\frac{5}{8}=0.625$ miles

Real, Irrational
