Answer:

<em>a</em><em>.</em><em> </em><em> </em><em>They</em><em> </em><em>are</em><em> </em><em>empty</em><em> </em><em>set</em><em>.</em>

<em>b</em><em>.</em><em> </em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>finite</em><em> </em><em>set</em><em>.</em>

<em>Solu</em><em>tion</em><em>,</em>

<em>a</em><em>.</em><em> </em><em>A</em><em>=</em><em>{</em><em> </em><em>prime</em><em> </em><em>number</em><em> </em><em>between</em><em> </em><em>6</em><em> </em><em>and</em><em> </em><em>7</em><em>}</em>

<em>There</em><em> </em><em>are</em><em> </em><em>not</em><em> </em><em>any</em><em> </em><em>number</em><em> </em><em>between</em><em> </em><em>6</em><em> </em><em>and</em><em> </em><em>7</em><em>.</em>

<em>So</em><em> </em><em>there</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>no</em><em> </em><em>Eleme</em><em>n</em><em>ts</em><em>.</em>

<em>A</em><em>=</em><em>{</em><em> </em><em>}</em>

<em>It</em><em> </em><em>is</em><em> </em><em>empty</em><em> </em><em>set</em><em>.</em>

<em>Empty</em><em> </em><em>set</em><em> </em><em>are</em><em> </em><em>those </em><em>set</em><em> </em><em>which</em><em> </em><em>does</em><em>n't</em><em> </em><em>contai</em><em>n</em><em> </em><em>any</em><em> </em><em>Element</em><em>.</em>

<em>b.B</em><em>=</em><em>{</em><em>multiples</em><em> </em><em>of</em><em> </em><em>2</em><em> </em><em>less</em><em> </em><em>than</em><em> </em><em>2</em><em>0</em><em>}</em>

<em> </em><em> </em><em>B</em><em>=</em><em>{</em><em>2</em><em>,</em><em>4</em><em>,</em><em>6</em><em>,</em><em>8</em><em>,</em><em>1</em><em>0</em><em>,</em><em>1</em><em>2</em><em>,</em><em>1</em><em>4</em><em>,</em><em>1</em><em>6</em><em>,</em><em>1</em><em>8</em><em>}</em>

<em>It</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>finite</em><em> </em><em>set</em><em>.</em>

<em>Finite</em><em> </em><em>set</em><em> </em><em>are</em><em> </em><em>those</em><em> </em><em>set</em><em> </em><em> </em><em>which</em><em> </em><em>we</em><em> </em><em>can</em><em> </em><em>count</em><em> </em><em>easily</em><em>.</em>

The answer to all 11.
madam [21]

Answer:

The rate of the current is 2 miles per hour.

Step-by-step explanation:

Let us assume that the rate of the river is v miles per hour.

The speed of the boat is 12 miles per hour.

Let us assume also that the boat can go 21 miles in t hours in the downstream and 15 miles upstream at the same time i.e. t hours.

So, from the condition given we can write that  

12 + v = \frac{21}{t} ......... (1), and  

12-v =\frac{15}{t} ......... (2)

Now, adding those two equations we get  

24 = \frac{21}{t} +\frac{15}{t} = \frac{36}{t}

⇒ t = \frac{3}{2} hours

Now, from equation (1), we get,  

12 + v = \frac{21}{\frac{3}{2} } =14

⇒ v = 2 miles per hour

Therefore, the rate of the current is 2 miles per hour. (Answer)

1) A boat traveled 448 miles downstream and back. The trip downstream took 14 hours. The trip
Serhud [2]

Answer:B

I think we are in the same class lol

Step-by-step explanation:448 divided by 14= 32

448 divided by 16= 28

B=speed of boat in water

Y= Speed of current

B+y=32

B-y=28

32 + 28 =60

60 divided by 2 = 30

32 -30 =2

B=30

Y=2
