9. Radha, a florist, has 112 roses, 91 gladioli, and 63 marigolds to be used to make bouquets. Shmake identical bouquets having all three varieties of flowers. What is the maximum number ofbouquets that Radha can make if she uses all the flowers?

Answer»

Given:

Radha, a florist, has 112 roses, 91 gladioli, and 63 marigolds to be used to make bouquets

She make identical bouquets having all three varieties of flowers

To FIND:

The maximum number of bouquets that Radha can make if she uses all the flowers

Solution:

To find the maximum no. of bouquets that Radha can make by using all the flowers that she has, we will calculate the H.C.F. of 112, 91 & 63.

We will calculate the H.C.F od 112, 91 & 63 by prime factorisation method:

Factors of 112, 91 & 63:

112 = 2 × 2 × 2 × 2 × 7

91 = 7 × 13

63 = 3 × 3 × 7

H.C.F.:

∴ H.C.F of 112, 91 & 63 = 7

Thus, the maximum number of bouquets that Radha can make if she uses all the flowers are 7.

5.	Find the quadratic polynomial whose sum and products of the zeros are 5 and -6
Answer» Answer: x² + x - 30 Step-by-step explanation: let the TWO zeros be a and B such that a=5 and b=-6 so, a+b= 5+ (-6)= -1 and, ab= 5*(-6)= -30 required POLYNOMIAL = x² - (a+b)x + ab = x² - (-1)x + (-30) = x² + x - 30

5.

Find the quadratic polynomial whose sum and products of the zeros are 5 and -6

Answer»

Answer:

x² + x - 30

Step-by-step explanation:

let the TWO zeros be a and B

such that a=5 and b=-6

so, a+b= 5+ (-6)= -1

and, ab= 5*(-6)= -30

required POLYNOMIAL = x² - (a+b)x + ab

= x² - (-1)x + (-30)

= x² + x - 30

13.	S=(2i+3j-5k)m and (6I-5j-4k)N what is work done by this force
Answer» GIVEN : $\sf{\vec S \: = \: (2 \hat{i} \: + \: 3 \hat{j} \: - \: 5 \hat{k}) \: m}$ $\sf{\vec F \: = \: (6 \hat{i} \: - \: 5 \hat{j} \: - \: 4 \hat{k}) \: N}$ To FIND : Work Done by Force SOLUTION : As we know that, $\implies \sf{W \: = \: \vec F. \vec S}$ Where, W is Work Done F is force S is Displacement Putting Values of $\sf{\vec F \: \: and \: \: \vec{S}}$ , $\implies \sf{W \: = \: \big[ (2 \hat{i} \: + \: 3 \hat{j} \: - \: 5 \hat{k}) . (6 \hat{i} \: - \: 5 \hat{j} \: - \: 4 \hat{k}) \big]} \\ \\ \implies \sf{W \: = \: \big[ (2 \: \times \: 6) \: + \: (3 \: \times \: -5) \: + \: (-5 \: \times \: -4) \big]} \\ \\ \implies \sf{W \: = \: (12 \: - \: 15 \: + \: 20)} \\ \\ \implies \sf{W \: = \: 32 \: - \: 15} \\ \\ \implies \sf{W \: = \: 17}$ $\therefore$ Work Done is 17 J $\rule{150}{2}$ Some Important Points : There are TWO types of Quantities vector and scalar. Vectors are those quantities which have magnitude as well are direction. Scalar quantities are those which have only magnitude, no direction. Example of vector quantities are acceleration, force, displacement, etc. Example of scalar quantities are Work Done, Speed, distance, etc. Product of Two vector quantities is always a scalar QUANTITY

13.

S=(2i+3j-5k)m and (6I-5j-4k)N what is work done by this force

Answer»

GIVEN :

$\sf{\vec S \: = \: (2 \hat{i} \: + \: 3 \hat{j} \: - \: 5 \hat{k}) \: m}$
$\sf{\vec F \: = \: (6 \hat{i} \: - \: 5 \hat{j} \: - \: 4 \hat{k}) \: N}$

To FIND :

Work Done by Force

SOLUTION :

As we know that,

$\implies \sf{W \: = \: \vec F. \vec S}$

Where,

W is Work Done
F is force
S is Displacement

Putting Values of $\sf{\vec F \: \: and \: \: \vec{S}}$ ,

$\implies \sf{W \: = \: \big[ (2 \hat{i} \: + \: 3 \hat{j} \: - \: 5 \hat{k}) . (6 \hat{i} \: - \: 5 \hat{j} \: - \: 4 \hat{k}) \big]} \\ \\ \implies \sf{W \: = \: \big[ (2 \: \times \: 6) \: + \: (3 \: \times \: -5) \: + \: (-5 \: \times \: -4) \big]} \\ \\ \implies \sf{W \: = \: (12 \: - \: 15 \: + \: 20)} \\ \\ \implies \sf{W \: = \: 32 \: - \: 15} \\ \\ \implies \sf{W \: = \: 17}$

$\therefore$ Work Done is 17 J

$\rule{150}{2}$

Some Important Points :

There are TWO types of Quantities vector and scalar.

Vectors are those quantities which have magnitude as well are direction.

Scalar quantities are those which have only magnitude, no direction.

Example of vector quantities are acceleration, force, displacement, etc.

Example of scalar quantities are Work Done, Speed, distance, etc.

Product of Two vector quantities is always a scalar QUANTITY

A 5m wide cloth is used to make a conical tent of Base diameter 14m and height 24m find the cost of the cloth used at the rate of Rs 25per meter

Answer»

$\large{\underline{\bf{\red{Given:-}}}}$

✦ Radius (r) = 14/2 = 7m

✦ Height (h) = 24m

$\large{\underline{\bf{\red{To\:Find:-}}}}$

✦ COST of the cloth used at the RATE of Rs 25/m

$\huge{\underline{\bf{\purple{Solution:-}}}}$

$\blue{ \bf\:slant \: height \: of \: tent \: (l) = \sqrt{ {r}^{2} + {h}^{2} } }\:\\$

$\mapsto \rm\: \sqrt{ {7}^{2} + {24}^{2} } \\ \\ \mapsto \rm\: \sqrt{49 + 576} \\ \\\mapsto \rm\: \sqrt{625} \\ \\\mapsto \bf\:25m \\\\ \:$

$\mapsto \rm \frac{22}{7} \times 7 \times 25 \\ \\\mapsto \rm22 \times 25 \\ \\\mapsto \bf550 {m}^{2} \\ \\$

LET x meter cloth is required:-
