Answer:

3z+2z+4=20-2z+5

Step-by-step explanation:

5z+4=25-2z

5z+2z=25-4

7z=21

z=21/7

z=3

ANSWER:

Therefore , if the NUMBERS are in propotion then

1/2 ÷ 1/3 = 1/5 ÷ 1/x

3/2 = x/5

3/2 × 5 = x

15/2 = x

Therefore , 15/2 ( OPTION C ) is the RIGHT answer ..

Answer:

114

Step-by-step EXPLANATION:

BC^2 = AB^2 - AC^2

BC = 8

AREA ABC = 60

AREA ADC = √p(p−a) (p−b) (p−c),  where p = a+b+c/2

AREA ADC = 54

total AREA = 54+60 =114

ANSWER

Given:

AB = 5 cm, BC = 12 cm

Using Pythagoras theorem,

AC ^2 =AB ^2 +BC ^2

= 5 ^2 +12 ^2

= 25+144

= 169

AC=13.

We know that two tangents drawn to a CIRCLE from the same POINT that is exterior to the circle are of EQUAL lengths.

So, AM=AQ=a

Similarly MB=BP=b and PC=CQ=c

We know

AB=a+b=5

BC=b+c=12 and

AC=a+c=13

Solving SIMULTANEOUSLY we get a=3,b=2 and c=10

We also know that the tangent is perpendicular to the radius

Thus OMBP is a square with side b.

Hence the length of the radius of the circle inscribed in the right angled triangle is 2CM.

Answer:

- 5 & - 2

Step-by-step explanation:

= > x² + 7x + 10

Split the middle TERM in such a WAY so that the product of those parts will be equal to the product of FIRST and last term:

Here, 7 = 5 + 2 , as 5 * 2 = 10

= > x² + (5 + 2)X + 10

= > x² + 5x + 2x + 10

= > x(x + 5) + 2(x + 5)

= > (x + 5)(x + 2)

Hence,

Zeroes of this polynomial are - 5 & - 2.

Given :  SEQUENCE -2 3 8 13.

To Find :  How many terms of the sequence  will make sum 568

Solution:

sequence -2 3 8 13.

a = - 2

d = 3 -(-2) = 5

n = term

Sum = (n/2)(2a + (n -1)d)

sum = 568

=> (n/2)(2*(-2) + (n-1)5) = 568

=> n(-4 + 5n - 5) = 1136

=> n(5n - 9) = 1136

=> 5n² - 9n  = 1136

=> 5n² - 9n - 1136 = 0

=> 5n² - 80N + 71n - 1136 = 0

=> 5n(n - 16) + 71(n - 16) = 0

=> (n - 16)(5n + 71) = 0

=> n = 16    , n = -71/5 ( which is not possible)

Hence n = 16

16 terms will make sum 568

ANSWER:

Option A Is Right

WHAT IS PROBABILITY?

• probability is the possible outcome of an event

• it predicts the possible outcome

EXAMPLES:

• outcome of a DIE rolled

• a card DRAWN randomly from deck of cards

• a ball picked randomly from a bag

• outcome of a TOSSED coin.

SOLUTION FOR QUESTION:

• the probability of an event must lie between 0 and 1

• it must neither be 0 nor 1

• the value must be rational.it can not be irrational

NOTE:

• Rational number has finite value

• irrational number has infinite value.

VERIFICATION

• OPTION A: 0.4

it is finite and lies between 0 and 1

• OPTION B:1.004

it is greater than one

• OPTION C :11/23

11/23=0.478...........

it is infinite

• OPTION D:18/11

18/11=1.63.......

it is infinite as well as greater than 1

ANSWER:

option a 0.4 satisfies all condition.

so the probability of an event may be 0.4

Question:

5. In fig 6.17, POQ is a line. Ray OR is perpendicular to line PQ. OS is another ray lying between rays OP and OR.

Prove that ∠ROS = ¹/₂ (∠QOS - ∠POS)

• SOLUTION:

Given:

OR ⊥ PQ  [OR is perpendicular to PQ]

∵ ∠QOR = 90°  

Now,

From the figure, we GET that

∠POR and ∠QOR are linear pair(sum = 180°)

⇒ ∠POR + ∠QOR = 180°

⇒ ∠POR + 90° = 180°    

[∵ from given ∠QOR = 90° ]

⇒ ∠POR = 180° - 90°

⇒ ∠POR = 90°

By looking at the figure, we also get that,

∠POR = ∠POS + ∠ROS

⇒ 90° = ∠POS + ∠ROS

⇒ 90° - ∠POS = ∠ROS  -------(i)

→ Also, ∠QOS and ∠POS are linear pairs.

⇒ ∠QOS + ∠POS = 180°

[Multiplying 1/2 to both the sides]

 ------(ii)

Now,

Will substitute the EQ.(ii) in (i), we get,

[Taking LCM 2 in RHS]

Hence proved.

Question

6. It is given that ∠XYZ = 64° and XY are produced to POINT P. Draw the figure from the given information. If ray YQ bisects ∠ZYP, find ∠XYQ and reflex ∠QYP.

• SOLUTION:

[see image 2]

Given -

∠XYZ = 64°

Here,

∠XYZ and ∠ZYP are linear pair (Sum = 180°)

⇒ ∠ XYZ + ∠ZYP = 180°

⇒ 64° + ∠ZYP = 180°

⇒ ∠ZYP = 180° - 64°

⇒ ∠ZYP = 116°

Also,

Ray YQ bisect ∠ZYP (Given)

∠QYZ = ∠QYP

Also,

∠ZYP + 64 = 180

⇒ ∠QYZ + ∠QYP + 64 = 180

⇒ ∠QYZ + ∠QYZ = 180 - 64

⇒ 2∠QYZ = 116

⇒ ∠QYZ = 116 ÷ 2

⇒ ∠QYP = 58°

Now,

∠XYQ = ∠QYZ + ∠XYZ

∠XYQ = 58 + 64

∠XYQ = 112°

So,

Reflex ∠QYP = 360 - ∠QYP

                      = 360 - 58

                      = 302°

Hence,

∠XYZ = 112°

And

Reflex ∠QYP = 302°
