On a map of North Carolina, 27 centimeters represents 18 miles. Based on the map, what equation would calculate the number of mi

ioda

Let y represent number of miles between the two cities and x represent number of cm between both cities.

We have been given that on a map of North Carolina, 27 centimeters represents 18 miles. We are asked to determine the equation that would calculate the number of miles between the two cities, y, when they measure x centimeters apart.

We will use proportions to solve our given problem.

$\frac{\text{Number of miles between two cities}}{\text{Number of cm between two cities}}=\frac{18}{27}$

Upon substituting our given values in above equation, we will get:

$\frac{y}{x}=\frac{18}{27}$

$\frac{y}{x}=\frac{2}{3}$

Now we will multiply both sides by x.

$\frac{y}{x}\cdot x=\frac{2}{3}\cdot x$

$y=\frac{2}{3}\cdot x$

Therefore, our required equation would be $y=\frac{2}{3}\cdot x$ and 1st option is correct choice.

Find the approximate value of √191 to the nearest tenth. What 2 numbers does it fall between when placed on a number line?

meriva

The approximate value of √191 to the nearest tenth is 13.8 and the two numbers that should fall on the number line is between 13-13.5.

Given that,

The square root of √191.

So, the approximate value of √191 is

$= \sqrt{191} \\\\= 13.82\\\\$

= 13.8

It shows that the two numbers that should fall between at the time when place on the number line is between 13-13.5.

Therefore we can conclude that the approximate value of √191 to the nearest tenth is 13.8 and the two numbers that should fall on the number line are between 13-13.5.
