3.	(c) On A PQR23. Find the largest and the smallest digit in the blank space of thegiven number. so that the number is divisible by 3.solution
Answer» Answer: Answer is 86724 Step-by-step explanation: _6724. The number is divisible by 3 if the sum of its digits is divisible by 3. Adding the digits of the given number, 6+7+2+4=19 If 2 is added to the above number then the number will BECOME 21 which is divisible by 3 and also, 2 is the SMALLEST number that can fill the MISSING space. Now, if 8 is added to the given number then the number will become 27 which is divisible by 3 and 8 is largest number that can make the given number divisible by 3. Therefore, the smallest number will be 2 which will FORM 26724 and the largest number will be 8 forming 86724.

(c) On A PQR23. Find the largest and the smallest digit in the blank space of thegiven number. so that the number is divisible by 3.solution

Answer»

Answer:

Answer is 86724

Step-by-step explanation:

_6724.

The number is divisible by 3 if the sum of its digits is divisible by 3.

Adding the digits of the given number,

6+7+2+4=19

If 2 is added to the above number then the number will BECOME 21 which is divisible by 3 and also, 2 is the SMALLEST number that can fill the MISSING space.

Now, if 8 is added to the given number then the number will become 27 which is divisible by 3 and 8 is largest number that can make the given number divisible by 3.

Therefore, the smallest number will be 2 which will FORM 26724 and the largest number will be 8 forming 86724.

16.	The two parallel sides and the height between them are in the ratio3:7:4. If the area of the trapezium is 180 cm”. Determine its height
Answer» Given: ✰ The two PARALLEL SIDES and the height between them are in the ratio 3:7:4. ✰ The area of the trapezium = 180 cm² To find: ✠ The height of the trapezium. Solution: Lets understand the concept first! First we will ASSUME that the two parallel sides and the height between them are 3x, 7X and 4x respectively. Then, we will use formula of area of trapezium to calculate the value of x. We will substitute the value of its two parallel sides, height and the area of trapezium. Then find out the value of x. After that we will substitute the value of x in the height of the trapezium to find out the actual height of the trapezium. Let the two parallel sides of the trapezium be 3x and 7x respectively, and the height of the trapezium be 4x. ✭ Area of trapezium = 1/2 × ( a + b ) × h ✭ Where, a and b are the parallel sides of the trapezium. h is the height of the trapezium that is the distance between its parallel sides. Putting the values in the formula, we have: ➤ 180 = 1/2 × ( 3x + 7x ) × 4x ➤ 180 = 1/2 × 10x × 4x ➤ 180 = 1/2 × 40x² ➤ 40x² = 180 × 2 ➤ 40x² = 360 ➤ x² = 360/40 ➤ x² = 9 ➤ x = √9 ➤ x = 3 Now, Substitute the value of x in height of trapezium. ➛ The height of the trapezium = 4x ➛ The height of the trapezium = 4 × 3 ➛ The height of the trapezium = 12 cm ∴ The height of the trapezium = 12 cm _______________________________

The two parallel sides and the height between them are in the ratio3:7:4. If the area of the trapezium is 180 cm”. Determine its height

Answer»

Given:

✰ The two PARALLEL SIDES and the height between them are in the ratio 3:7:4.

✰ The area of the trapezium = 180 cm²

To find:

✠ The height of the trapezium.

Solution:

Lets understand the concept first! First we will ASSUME that the two parallel sides and the height between them are 3x, 7X and 4x respectively. Then, we will use formula of area of trapezium to calculate the value of x. We will substitute the value of its two parallel sides, height and the area of trapezium. Then find out the value of x. After that we will substitute the value of x in the height of the trapezium to find out the actual height of the trapezium.

Let the two parallel sides of the trapezium be 3x and 7x respectively, and

the height of the trapezium be 4x.

✭ Area of trapezium = 1/2 × ( a + b ) × h ✭

Where,

a and b are the parallel sides of the trapezium.
h is the height of the trapezium that is the distance between its parallel sides.

Putting the values in the formula, we have:

➤ 180 = 1/2 × ( 3x + 7x ) × 4x

➤ 180 = 1/2 × 10x × 4x

➤ 180 = 1/2 × 40x²

➤ 40x² = 180 × 2

➤ 40x² = 360

➤ x² = 360/40

➤ x² = 9

➤ x = √9

➤ x = 3

Now, Substitute the value of x in height of trapezium.

➛ The height of the trapezium = 4x

➛ The height of the trapezium = 4 × 3

➛ The height of the trapezium = 12 cm

∴ The height of the trapezium = 12 cm

6. One zero of the polynomial x2 – 2x - (7p+ 3), find the value of p and theother zero.Pls ans as fast

Answer»

Answer: hope its helps to you

Step-by-step explanation:

Given

One ZERO of the polynomial x2 - 2x - (7P + 3), find the value of p and the other zero.

ANSWER

Given f(x) = x^2 – 2 x – (7 p + 3)

Given one zero of polynomial f(x) = - 4 and other zero be a

So sum of zeroes = coefficient of x / coefficient of x^2

-4 + a = - (- 2)/1

-4 + a = 2

a = 2 + 4 = 6

The other zero is 6

Now product of zeroes = constant term / coefficient of x^2

-4 x 6 = - (7 p + 3) / 1

-24 = - (7 p + 3)

7 p + 3 = 24

7 p = 24 – 3

7 p = 21

P = 3

So the value of p is 3
