Give four rational number equivalent to 5/6 and how it is​

Answer»

Answer:

\frac{10}{12} , \frac{15}{18} , \frac{20}{24} , \frac{25}{30}

Step-by-step explanation:

We need to multiply by EQUIVALENT fractions i.e\frac{10}{12}

\frac{5}{6} ×\frac{2}{2} = \frac{10}{12}

\frac{5}{6} X \frac{3}{3} = \frac{15}{18}

\frac{5}{6} x \frac{4}{4} = \frac{20}{24}

\frac{5}{6} x \frac{5}{5} = \frac{25}{30}

Find the least number which when divided by 12, 16, 24 and 36 leaves a remainder 7 in each case ?

Answer»

SOLUTION :

For this particular SUM we need to find the LCM of the given numbers.

The smallest NUMBER which when divided by 12 16 24 and 36 = LCM of 12 16 24 and 36

12 = 2×2×3

16 = 2×2×2×2

24 = 2×2×2×3

36 = 2×2×3×3

LCM = 144

The smallest number which DIVIDES 12 16 24 and 36 is 144. But we have a condition that it leaves a remainder of 7. So we add 7 to the LCM (144+7=151).

Hence the smallest number that when divided by 12 16 24 and 36 leaves a remainder 7 is 151.

Find the mean proportion between a-b/a+b and a²b²/a²-b²

Answer»

Solution :-

we KNOW that,

  • Mean proportion of x and y = √(x * y)

we have,

  • x = (a - B) / (a + b)
  • y = (a²b²) / (a² - b²)

so,

→ Mean proportion = √[{(a - b) / (a + b)} * {(a²b²) / (a² - b²)}]

→ Mean proportion = √[{(a - b)(a²b²)} / {(a + b)(a² - b²)}]

PUTTING :-

  • a² - b² = (a + b)(a - b)

→ Mean proportion = √[(a²b²) / (a + b)²]

→ Mean proportion = ab / (a + b) (Ans.)

Prove De Morgan’s law for (A∩ B)ʹ = Aʹ ∪ Bʹ​

Answer»

Hey friend!

Here is your ANSWER:

To prove De Morgan's Law for ( A ∩ B )' = A' ∪ B'

Proof:

Let M = (A ∩ B)' and N = A' U B'

Let x be an arbitrary element of M

then x ∈ M ⇒ x ∈ (A ∩ B)'

⇒ x ∉ (A ∩ B)

⇒ x ∉ A or x ∉ B

⇒ x ∈ A' or x ∈ B'

⇒ x ∈ A' U B'

⇒ x ∈ N

⇔ M ⊂ N …………….. (i)

Again,

Let y be an arbitrary element of N

then y ∈ N ⇒ y ∈ A' U B'

⇒ y ∈ A' or y ∈ B'

⇒ y ∉ A or y ∉ B

⇒ y ∉ (A ∩ B)

⇒ y ∈ (A ∩ B)'

⇒ y ∈ M

⇔ N ⊂ M …………….. (II)

Now,

From (i) and (ii) we GET;

→  M = N

→ (A ∩ B)' = A' U B'

Hence proved

Find 5 rational numbers between 8 and 9​

Answer»

Answer:

81/10, 41/5, 83/10, 42/5, 17/2 are the five rational NUMBERS between 8 and 9.

Step-by-step explanation:

In these types of QUESTION, you have to increase the denominator by multiplying an integer in both numerator and denominator. It depends upon the number of rational number asked.

Here, for simplifying the question, MULTIPLY the denominator with 10 of both the numbers (8 and 9).

We get, 80/10 and 90/10,

Now, it's very easy to find out 5 rational numbers between 80/10 and 90/10.

We get, 81/10, 82/10 = 41/5, 83/10, 84/10 = 42/5, 85/10 = 17/2 as five rational numbers between 8 and 9.

You can ALSO write it simply as 81/10, 82/10, 83/10, 84/10, 85/10.

II.Factorise the fol2(1) 24a’ + 37a - 5​

Answer»

<P>Step-by-step EXPLANATION:

Correct question :-

  • Factorise the given polynomial p(a) = 24a² + 37a - 5

To Find -

  • Zeroes of the polynomial

Solution :-

Now,

→ 24a² + 37a - 5

By middle term splitt :-

→ 24a² + 40a - 3a - 5

→ 8a(3a + 5) - 1(3a + 5)

→ (8a - 1)(3a + 5)

Zeroes are -

→ 8a - 1 = 0 and 3a + 5 = 0

→ a = 1/8 and a = -5/3

Verification :-

  • α + β = -b/a

→ -5/3 + 1/8 = -(37)/24

→ -40 + 3/24 = -37/24

→ -37/24 = -37/24

LHS = RHS

And

  • αβ = c/a

→ -5/3 × 1/8 = -5/24

→ -5/24 = -5/24

LHS = RHS

Hence,

Verified...

It shows that our answer is absolutely correct.
