<u>Answer: </u>

The square root of 258.75 is \frac{3 \sqrt{115}}{2}

<u>Solution:</u>

Here we have to find the square root of 258.75. First we convert the decimal value into a fraction value. Converting 258.75 in fraction we get

\frac{258.75 \times 100}{100}

=\frac{25875}{100}

Now we find the factors of 25875 and 100

Factors of 25875 = 3 \times 3 \times 5 \times 5 \times 5 \times 23

Since we have to find the square root, we group two same numbers together and place them outside square root. Grouping two threes and two five’s we get square root of  

25875=3 \times 5 \sqrt{5 \times 23}

=15 \sqrt{115}

Now the factors of 100 = 2 \times 2 \times 5 \times 5

The square root of 100 = 2 \times 5 = 10

\text { Square root } \sqrt{258.75}=\frac{\sqrt{25875}}{\sqrt{100}}

=\frac{15 \sqrt{115}}{10}

Cancelling the numerator and denominator by 5, we get

=\frac{3 \sqrt{115}}{2}

Hence the square root of 258.75 is \frac{3 \sqrt{115}}{2}

Let Z={a,c,{a,b}}. What is |Z|?
Lina20 [59]

Z=\{a,c,\{a,b\}\}

\boxed{|Z|=3} (treat \{a,b\} as one element of Z)

The power set of Z is

\boxed{2^Z=\bigg\{\{\},\{a\},\{c\},\big\{\{a,b\}\big\},\{a,c\},\big\{a,\{a,b\}\big\},\big\{c,\{a,b\}\big\},\big\{a,c,\{a,b\}\big\}\bigg\}}

1. \{a,c\}\subseteq Z is true because both a\in Z and c\in Z.

2. a\in Z is true.

3. \{c\}\subseteq Z is true (same reason as part 1).

4. \{c\}\in Z is false because Z does not contain the set \{c\}, rather just the element c itself.

5. b\in Z is false because the element b on its own simply is not in Z. That b\in\{a,b\} does not mean b\in Z, but that b belongs to a subset of Z.

6. \{a,b\}\in Z is true.

A number is divisible by 3 if the sum of the digits is divisible by 3 true or false ​
shtirl [24]
ANSWER:
It is true as the divisibility rule of three says -
WE HAVE TO ADD ALL THE DIGITS OF THE NUMBER AND IF THAT SUM IS DIVISIBLE BY THREE THEN THE PARTICULAR NUMBER IS DIVISIBLE BY THREE.
EXAMPLE 2+7=9 and 3*3=9

What is the answer Factorise: 2x² +7x+6.<br><br>​
Mila [183]

Answer:

2x  + 3 )(x   + 2 )

Step-by-step explanation:

2x² + 7x + 6          

Find two numbers multiplied together to get 6

and if you multiply one by 2, the answer is 7:

Tested:                                  

6 & 1  but 6 · 2 + 1 = 13 or 6 + 2 · 1  = 8 No

2 & 3  and 2 · 2 + 3 = 7    Yes

2x² = 2x  & x

 all signs are positive

   trinomial  factoring  (            )(            )

                                     (     +     )(      +    )

    2 and 3 are the numbers to use    (2x  + 3 )(x   + 2 )   or     (2x + 2) (x + 3)

The largest number goes with the 2x.

Therefore (2x  + 3 )(x   + 2 )

Check 2x(x + 2) + 3(x + 2)

              2x² + 4x + 3x + 6

              2x² + 7x + 6         checked
