Explain why angle is considered a defined term in geometry.

77julia77 [94]

Answer:

An angle is considered a defined term in geometry because defined terms are terms that have a formal definition and can be defined using other geometrical terms.

Angle: Two rays that share the same endpoint, however, the rays take off in different directions. The area in the middle of the two rays is the angle measure.

A pitcher holds 3/4 gallons of kool-aid. Martin wants to pour equal amounts of kool- aid into 6 smaller cotainers. How much kool

statuscvo [17]

Answer:

$\dfrac{1}{8}\ gallons$

Step-by-step explanation:

Amount of kool - aid that the pitcher can hold = $\frac{3}4$ gallons

There are 6 smaller containers in which this kool - aid is to be adjusted.

Also, the volume of the smaller containers is equal to each other i.e. the containers are identical to each other in terms of volume.

To find:

The amount of kool - aid that each container can hold?

Solution:

Volume of all the smaller containers combined = Volume of the kool - aid available

Let the volume of one smaller container = $V$

$V + V + V + V + V + V = \dfrac{3}{4}\ gallons$

$\Rightarrow 6V = \dfrac{3}{4}\ gallons\\\Rightarrow V = \dfrac{3}{4\times 6 }\ gallons\\\Rightarrow V=\bold{\dfrac{1}{8}\ gallons}$

$\frac{1}{8}\ gallons$ of kool - aid is the amount that each smaller can hold.

Do decimals have opposites? explain

dybincka [34]

Presumably, the opposite of decimals are fractions because by dividing the two numbers you get the decimal value of the fractional form of the number. Refer to the example below.

How do you write 39/100 into a decimal form is by simply dividing 39 to 100. 
Hence, 
1. 39 / 100 = 0.39 -> Hence this is the decimal form.

0.39 is the decimal form of the given value. 
Other examples can include: 
1. 100 / 1000 = 0.1 
2. 45 / 10 = 4.5

A flute instructor examined student progress.he found that playing a longer song does not necessarily mean that a student will h

Sunny_sXe [5.5K]

Answer:

The flute instructor can conclude that the length of the song does not have a direct variation or correlation with the number of incorrect notes.

Step-by-step explanation:

Direct variation and correlation means that as the "x" variable increases, the "y" variable will change according to it.

If the flute instructor took numerical data, for example, made a chart, and graphed it, then he would not find a trend.

It would probably look like this (see first photo). The plotted points are all over the place. ("x" is the song length, "y" is the number of incorrect notes).

If there was a correlation, then the data would look more like a straight line (see second photo).
