Find the distance between each pair of numbers on the number line; then find the coordinate of their midpoint.

quester [9]

Answer:

d = 1 7/24 or 31/24; midpoint would be half of that,or 31/48

Step-by-step explanation:

Since distance is absolute value, add 2/3 and 5/8 to get the entire distance. Midpoint is that distance divided by 2.

In circle P, if the radius is 3 cm, what is the length of arc AD?

umka21 [38]

Hello there.

We have for a circle that:

$\ell=\alpha r$

Where:

$\ell$ is the measure of the arc

$\alpha$ is the measure of the angle (radians)

$r$ is the radius of the circle

In our case, we have $\alpha = 120^\circ = \dfrac{120}{180}\pi = \frac23\pi ~rad$

We have r = 3 cm, then:

$\ell = (\frac23\pi )(3\ cm)\\ \\ \boxed{\ell = 2\pi~cm}$

Answer:

42300000

Step-by-step explanation:

Use known fact

$1\ km=1000\ m$

Consider 1 square kilometer:

$1\ km^2=1\ km\times 1\ km=1000\ m\times 1000\ m=1000000\ m^2$

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

$42.3\ km^2=42.3\times 1000000\ m^2=42300000\ m^2$
