Define each following sets by listing its elements, the set of letters in the word "salt"
leonid [27]

The word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

<h3>What is set?</h3>

A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.

We have given letter:

"salt"

Here, no letter is repeated.

So we can write it as roaster form:

Let's denote the set as S

S = {s, a, l, t}

Number of element in the set = 4

We can make new set from it if the set has only vowels

S(v) = {a}

If set has only consonants:

S(c) = {a, l, t}

Thus, the word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

If I can paint a wall in 20 min and my friend can paint a wall in 30 min. How many minutes would it take for us to paint a wall
ra1l [238]

Answer: 12\ \text{min}

Step-by-step explanation:

Given

It takes 20 min and 30 min for  a person and his friend to paint a wall individually  i.e.

In 1 min they cover \frac{1}{20} part and \frac{1}{30} part of wall respectively.

If the work together, 1 minute work is

\Rightarrow \dfrac{1}{20}+\dfrac{1}{30}\\\\\Rightarrow \dfrac{3+2}{60}\\\\\Rightarrow \dfrac{5}{60}

Time required will be reciprocal of it

\Rightarrow \dfrac{60}{5}=12\ \text{min}

Refer to the figure below. If m&lt;60 degrees l, find the measure of the other angles. Show your work(or explain) to receive ful
gladu [14]
All of the angles combined =360 degrees

Vertical angles are congruent, so if angle 1 = 60, so does angle 3

Logically we have to find the measure of angle 4 and angle 2 combined and divide by 2

60 + 60 = 120

360 - 120 = 240

240 / 2 = 120

angle 4 = 120
angle 2= 120

angle 3 = 60
