In order to have an accurate measurement system, humans would’ve had to have created one. Although body parts could be used to measure things, the lengths would’ve been different everytime. This is because no human’s body part is the exact same length as another’s. Everybody’s bone structure is different so in order to create a universally correct measurement system, humans had to invent a new one.

Whats the distance between {-4 , 12} and {18 , 12}
belka [17]
You would need to use the distance formula.
Distance = Sqrt((x2-x1)^2+(y2-y1)^2)
Plug in your numbers
Distance = Sqrt((12+4)^2+(12-18)^2)
Distance = 17.09

Graph + > -1.
andrew-mc [135]

You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.

In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.

QveST [7]

The question has missing details

The m<em>issing options are: </em>

<em>A. 188,000 square yards </em>

<em>B. 138,000 square yards </em>

<em>C. 600 square yards </em>

<em>D. 300 square yards</em>

<em>See attachment 1 for the missing diagram</em>

Answer:

<em>B. 138,000 square yards </em>

Step-by-step explanation:

The figure can be divided into two shapes (see attachment 2)

From attachment 2,

The dimension of the big rectangle is 1300ft by 800ft

The dimension of the small rectangle is 500ft by 400ft

So, the area is:

Area of the big rectangle added to the area of the small rectangle

i.e.

Area = 1300 * 800 + 500 * 400

Area = 1040000 + 200000

Area = 1240000ft^2

Convert to yd^2 by dividing by 9

Area = 1240000yd^2 /9

Area = 137777.777778\ yd^2

<em>From the list of given options, the closest to the area of the diagram is </em>

<em>B. 138,000 square yards  </em>

<em></em>

What is the value of tan x°?
dmitriy555 [2]
Hi there!

\tan(x)  =  \frac{opposite \: side}{adjecent \: side}
\tan(x)  =  \frac{8}{6}
\tan(x)  = 1 \frac{1}{3}

x = 53.1
Therefore tan x° = 1 1/3 and x = 53.1°
