Find the distance between (3,5)<br> and (7,-3). **(round to the nearest tenth.)
BigorU [14]

Answer:

The answer is

<h2>8.9 units</h2>

Step-by-step explanation:

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

<h3>d =  \sqrt{( {x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

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

From the question the points are

(3,5)and (7,-3)

The distance between them is

<h3>d =  \sqrt{( {3 - 7})^{2}  +  ({5 + 3})^{2} }  \\  =  \sqrt{ ({ - 4})^{2} +  {8}^{2}  }  \\  =  \sqrt{16 + 64}  \\  =  \sqrt{80}  \\  =4  \sqrt{5}   \\   \:  \:  \:  \: = 8.9442</h3>

We have the final answer as

<h3>8.9 units to the nearest tenth</h3>

Hope this helps you

Kipish [7]

Answer:

Step-by-step explanation:

The number of eggs in the carton = 12

The capacity of egg carton is depicted as e

Hence, the inequality e<12 in this context means that :

The number of eggs in the carton is less than the capacity of the egg carton

Thus we can conclude that the number of eggs in the carton is not up to 12, which is the number of eggs the carton can hold.
