7554.

If a+b = 4 and ab= -12, find 1) a-b2) a^2 - b^2

Answer»

Answer:

Given,

a+b=3 ,

a-b=2,

(a+b)^2=a^2+b^2+2ab————-(1)

(a-b)^2=a^2–2ab+b^2————(2)

(1)-(2)=>(a+b)^2-(a-b)^2=2(a^2+b^2)

=>(3)^2-(2)2=2(a^2+b^2)

=>6–4=2(a^2+b^2)

=>2=2(a^2+b^2)

the VALUE of 2 (a^2+b^2) is 2

7563.

You are 25 years younger than your mother. Your mother is 36 years old. How old are you now ?

Answer»

Answer:

And your age “b”

a+b=60

a-b=25(as you are younger by 25 YEARS)

a= b+25

So PUTTING a’s value in first equation

b+b+25=60

2b=60–25

2b=35

b=17.5

So a=42.5

Hence you mother’s age: 42 years 6 months.

Your age: 17 years 6 months.

Live long loving healthy life.

Topic

Binary

Binary is a number system of base 2. Digits of binary consist of 0 and 1. DIGIT by digit, the exponent of the base grows by 1.

Example) $1_{(2)}=1$ , $10_{(2)}=2$ , $100_{(3)}=4$ , ….

Since the question is giving $*$ and $\bullet$ as digits, the GIVEN number system is binary.

For example, 4 is 100₍₂₎ in binary. So it will be $\bullet\ *\ *$ in the given form.

Solution

43. $\bullet\ \bullet\ \bullet$ is added to $\bullet\ *\ *$ .

⇒ $111_{(2)}$ is added to $100_{(2)}$ .

$\implies 111_{(2)}+100_{(2)}=1011_{(2)}$

⇒ (b) $\bullet\ *\ \bullet\ \bullet$ is the required option.

44. Which binary number represents 15?

Via the repeated division by 2 method, we find the number in the binary form.

$\implies 15=1111_{(2)}$

⇒ (c) $\bullet\ \bullet\ \bullet\ \bullet$ is the required option.

45. If $11100_{(2)}$ is divided by $111_{(2)}$ , we are dividing $28$ by $7$ of decimal.

$\implies 4=100_{(2)}$

⇒ (a) $\bullet\ *\ *$ is the required option.

46. Which number represents 20?

$\implies 20=10100_{(2)}$

⇒ (d) $\bullet\ *\ \bullet\ *\ *$ is the required option.

47. Which number represents 15% of 80?

Firstly, in decimal, the required number is $80\times \dfrac{15}{100} =12$ .

Via the repeated division method, we find $12$ in the binary form.

$\implies 12=1100_{(2)}$

⇒ (b) $\bullet\ \bullet\ *\ *$ is the required option.

More Information

In the repeated division by 2 method, we use the REMAINDER and the last quotient. The name is because of dividing the quotient repeatedly by 2.

Answer»

Given : The weekly wages of 1000 workmen are NORMALLY distributed around a mean of 70 and a standard deviation of 5

To Find : estimate the NUMBER of workers whose weekly wages will be

More than 75

Less than 63

Solution:

Mean = 70

SD = 5

Z score = ( VALUE - Mean ) / SD

More than 75

=> z score = ( 75 - 70)/5 = 1

=> 84.13 % less than 75 Hence 15.87 % more than 75

=> 1000 * 15.87 /100 = 158.7 = 159

159 workers whose weekly wages will be More than 75

Less than 63

=> z score = ( 63 - 70)/5 = -1.4

= 8.08 % less than 63

=> 1000 * 8.08 /100 = 80.8 = 81

81 workers whose weekly wages will be Less than 63

If five times a certain integer is subtracted from the square of the integer, the integer is 63, find the integer

Answer»

Step-by-step EXPLANATION:

Five times a number 5X

Twice the X^2 =2X^2

2X^2-5X =63

2X^2-5X -63=0

a=2 b= -5 c= -63

X =[ 5+ — (25 -4×2×-’63)] / 2×2 =[5+ —(529)^1/2] /4

[Note : (529)^1/2 =23]

X1=(5+23)/4 =7

X2 =(5 -23)/4 = -18/4 not integer

Answer» ANSWER: option D) 8cm Step-by-step explanation: So it's given that ∆ABC is similar to ∆DEF now ots a property of similar triangles that the ratio of their areas is equal to the square of ratio of their SIDES i.e 64/121=(BC/EF)² so BC=8x cm (the x denotes that BC is some integral multiple of 8) (also the question is incorrect because you have been given a ratio of areas but have no information about any sides which makes it impossible to find any side by the ratio.) we can say for a fact that BC is some integral multiple of eight but we can't deduce its ACTUAL value. But I guess if you WRITE this you won't get any marks and there is no 'none of the above' so as far as this question goes the answer is 8cm but the question is wrong.

Plz guys step by step explain plz dont spam

Answer»

ANSWER:

option D) 8cm

Step-by-step explanation:

So it's given that ∆ABC is similar to ∆DEF

now ots a property of similar triangles that the ratio of their areas is equal to the square of ratio of their SIDES i.e

64/121=(BC/EF)²

so BC=8x cm (the x denotes that BC is some integral multiple of 8)

(also the question is incorrect because you have been given a ratio of areas but have no information about any sides which makes it impossible to find any side by the ratio.)

we can say for a fact that BC is some integral multiple of eight but we can't deduce its ACTUAL value. But I guess if you WRITE this you won't get any marks and there is no 'none of the above' so as far as this question goes the answer is 8cm but the question is wrong.

Than, Angle 1 = 3x = 3 * 15 = 45 degree Angle 2 = 4x = 4 * 15 = 60 degree Angle 3 = 5x = 5 * 15 = 75 degree. ￣￣￣￣￣￣￣￣￣￣￣￣ ☞For verification :- 45 degree + 60 degree + 75 degree = 180 degree. ￣￣￣￣￣￣￣￣￣￣￣￣ *Hopes,* *it's* *helpful.

If the angles of a triangle are in the ratio 3:4:5 determine the three anglesstep by step plz

Answer»

☞Given :-

The three angles of a triangle are in the ratio 3 :4 :5.

￣￣￣￣￣￣￣￣￣￣￣￣

☞To find :-

Find the three angles of the triangle ?

￣￣￣￣￣￣￣￣￣￣￣￣

☞Formula used :-

3 angles of the triangle = 180 degree ( sum of all sides of triangle is 180 degree)

￣￣￣￣￣￣￣￣￣￣￣￣

☞Solution :-

First,

Let the ratio 3:4:5 be 3X, 4x and 5x.

so,

2X + 3x + 4x = 180 degree

12x = 180 degree

$x = \frac{180}{12}$

x = 15.

Than,

Angle 1 = 3x = 3 * 15 = 45 degree

Angle 2 = 4x = 4 * 15 = 60 degree

Angle 3 = 5x = 5 * 15 = 75 degree.

￣￣￣￣￣￣￣￣￣￣￣￣

☞For verification :-

45 degree + 60 degree + 75 degree = 180 degree.

￣￣￣￣￣￣￣￣￣￣￣￣

Hopes, it's helpful.

SOLUTION

Note that:

You can only add inequalities when their signs are in the same direction:

If

and

(signs in same direction:

and

) -->

.

Example:

and

-->

.

You can only apply subtraction when their signs are in the opposite directions:

If

and

(signs in opposite direction:

and

) -->

(take the sign of the INEQUALITY you subtract from).

Example:

and

-->

.

Back to the ORIGINAL question:

If x + y + Z > 0, is z > 1?

(1) z > x + y + 1 --> as the signs are in the same direction we can add TWO inequalities:

-->

-->

, so z may or may not be more than 1. Not sufficient.

(2) x + y + 1 < 0 --> as the signs are in the opposite direction we can subtract two inequalities:

-->

-->

. Sufficient
