Find the distance between each pair of points. Round to the nearest tenth.
Vsevolod [243]

Answer:

The answer is

<h2>6.7 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M ( 4 , 0) and L ( - 2 , - 3)

The distance between them is

|ML|   =   \sqrt{( {4 + 2})^{2} +(  {0 + 3})^{2}  }  \\  =  \sqrt{ {6}^{2}  +  {3}^{2} }  \\  =  \sqrt{36 + 9}  \:  \:   \\  =  \sqrt{45 }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 3 \sqrt{5}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 6.7082039

We have the final answer as

<h3>6.7 units to the nearest tenth</h3>

Hope this helps you

8. Noah rides his motorcycle 90 miles in 2 hours 30 minutes. What is his average speed in
Nookie1986 [14]

Hey there! I'm happy to help!

We see that Noah rides his motorcycle 90 miles is 2 hours and 30 minutes, which is 150 minutes. We want to find his mph. To find this his mph, we want to find how far he has gone in one hour.

How much bigger is 150 than 60?

150/60=2.5

150 is 2.5 times bigger than 60. This means that we need to divide 90 by 2.5 to figure out how far Noah rode in 1 hour.

90/2.5=36

Therefore, Noah's average speed is 36 mph.

Have a wonderful day! :D
