One number is three less than two times another. If their sum is increased by five the result is fourteen. Find the numbers

Answer»

Answer:

let that unknown NUMBERS be x and y respectively

as given PER condition

x^{2}-3=y

Now it is given that there sum is 14 when increased by 5

i.e.,x+y+5=14

x+y=14-5

x+y=9

Now we WANT the numbers that sums 9 in place of x and y

So,if we TAKE x=3 so our y=6

             x^{2}-3=y

            3^{2}-3=6

            9-3=6

            6=6

           LHS=RHS

Hence ,VERIFIED that two unknown numbers are 3 and 6

THANK YOU

If =a+b, find the values of a and b

Answer»

Given

\dfrac{3}{2-\sqrt{2} } = a+b\sqrt{2}

LHS

= \dfrac{3}{2-\sqrt{2} }

= \dfrac{3}{2-\sqrt{2} } \times \dfrac{2+\sqrt{2} }{2+\sqrt{2} }

= \dfrac{6+3\sqrt{2} }{(2)^{2} -(\sqrt{2})^{2} }

= \dfrac{6+3\sqrt{2} }{4-2 }

= \dfrac{6+3\sqrt{2} }{2 }

= 2 + \dfrac{3\sqrt{2} }{2}

Therefore,

\boxed{\boxed{\bold{a=2}}}}}}}}}

\boxed{\boxed{\bold{b=\frac{3}{2} }}}}}

For an arithmetic sequence, a26=80. If the common difference is 1, find: a1= the sum of the first 43 terms=

Answer»

Step-by-step explanation:

TN = a + (n-1) d

T26 = 80

d= 1

80= a + (26-1)*1

80 = a + 25

a = 80-25

a = 55

a1 = 55

Sn = 1/2{2a + (n-1)d}

S43 = 1/2 {2*55 + (43-1)*1}

= 1/2 (110 + 42)

= 55 + 21

= 76

S43 = 76

I hope it is helpful for you..!!

Sum of two rational number is minus 3 upon 5 if one of the number is minus 9 upon 20 find the other rational number

Answer»

Answer:

The answer is -3/20(The other RATIONAL NUMBER)

Step-by-step explanation:

To FIND the other rational number

Step = Let the UNKNOWN other rational number be x

And equate the addition of the two rational numbers with their sum

That is,

-9/20 + x = -3/5

x = -3/5 + 9/20

Now take the L.C.M of the denominators[5 and 20]

That is 20

So,

-3/5 X 4/4 and 9/20 X 1/1(To make the denominators EQUAL)

-12/20 and 9/20

Now,

x = -12/20 + 9/20

  = -12 + 9/20

   = -3/20(The other rational number)

Simultanius linear eqution for 5x+7y=66 , 2x-3y=-20

Answer»

ANSWER:

x=54.5;y=8.

Step-by-step explanation:

5x+7y=66

5x=66-7y

x=66-7y/5

eqn.2. 2x-3y=-20

substituting VALUE of x in eqn.2 we get

2(66-7y/5)-3y=-20

by solving this we get value of y=8

so x=66-7×8/5

=66-56/5

=54.5=x

A bag contains 18red balls and 4blue.What percentage of balls are red?

Answer»

Given

\bold{Total \ number \ of \ <klux>RED</klux> \ balls} = 18

\bold{Total \ number \ of \ blue \ balls} =4

\bold{Total \ number \ of \  balls}\\ =4+18 \\= 22

To Find

Percentage of red balls

FORMULA TO BE USED

= \sf \dfrac{Number \ of \ red \ balls}{Total \ number \ of \ balls} \times 100

=\dfrac{18}{22} \times 100

=\dfrac{1800}{22}

= 81.81\%

\boxed{\boxed{\bold{Therefore, \ the \ percentage \ of \ red \ balls \ is \ 81.81 \ \%}}}}}}

In a survey it was found that 21 people liked product A , 26 like product B & 29 liked product C. If 14 people liked product A & B. 12 people like product C & A . 14 people liked product B & C and 8 liked all the three . Find (a ) how many like C only (b) how many like A& B but not C(c) How many like B or C bot not A(d)how many like at least 2 (e) how many like exactly 1 product

Answer»

ANSWER:

Hello MATE:)

Step-by-step explanation:

Let A, B, and C be the set of people who LIKE product A, B, and C respectively. 

n(A) = 21, n(B) = 26, n(C) = 29, n(A ∩ B) = 14, n(C ∩ A) = 12, n(B ∩ C) = 14, n(A ∩ B ∩ C) = 8 

People who many liked product C only 

= n(C) - n(C ∩ A) - n(B ∩ C) + n(A ∩ B ∩ C) 

= 29 -12 – 14 + 8 

= 11 

Hence, 11 liked product C only.

Find the value of k such that the polynomial x2-(k+r)x+2(2k-1)

Answer»

Answer:

Hello:

Step-by-step explanation:

Let α and β are the roots of GIVEN quadratic equation x² - ( k +6)x + 2(2k +1) = 0 [ you did mistake in typing of equation , I just CORRECT it ]

Now, sum of roots = α + β = - {-( k + 6)}/1 = (k + 6)

product of roots = αβ = 2(2k + 1)/1= 2(2k + 1)

A/C to QUESTION,

sum of roots ( ZEROS ) = 1/2 × products of roots zeros

⇒ (k + 6) = 1/2 × 2(2k + 1)

⇒ (k + 6) = (2k + 1)

⇒ k + 6 = 2k + 1

⇒ k = 5

Hence, k = 5

find the length of the median of triangle whose vertices are 1 , - 1 , 0,2 and -5,3 ... plz can any one help ..........​

Answer»

We have to find the lengths of the medians of a triangle whose co-ordinates of the vertices are A (0,-1); B (2, 1) and C (0, 3)

So we should find the mid-points of the sides of the triangle.

In general to find the mid-point P(x,y) of two points

A

(

x

1

,

y

1

)

A(x1,y1) and

B

(

x

2

,

y

2

)

B(x2,y2) we use section FORMULA as,

P

(

x

,

y

)

=

(

x

1

+

x

2

2

,

y

1

+

y

2

2

)

P(x,y)=(x1+x22,y1+y22)

Therefore mid-point P of side AB can be written as,

P

(

x

,

y

)

=

(

2

+

0

2

,

1

−

1

2

)

P(x,y)=(2+02,1-12)

Now EQUATE the individual terms to get,

x = 1

y = 0

So co-ordinates of P is (1, 0)

Similarly mid-point Q of side BC can be written as

Q

(

x

,

y

)

=

(

2

+

0

2

,

3

+

1

2

)

Q(x,y)=(2+02,3+12)

Now equate the individual terms to get,

x = 1

y = 2

So co-ordinates of Q is (1, 2)

Similarly mid-point R of side AC can be written as,

R

(

x

,

y

)

=

(

0

+

0

2

,

3

−

1

2

)

R(x,y)=(0+02,3-12)

Now equate the individual terms to get,

x =1

y= 2

So co-ordinates of Q is (1, 2)

Similarly mid-point R of side AC can be written as,

R

(

x

,

y

)

=

(

0

+

0

2

,

3

−

1

2

)

R(x,y)=(0+02,3-12)

Now equate the individual terms to get,

x = 1

y = 1

So co-ordinates of R is (0, 1)

Therefore LENGTH of median from A to the side BC is,

You lend $1500 to a friend for four months at an interest rate of 4 ¾% per year. What total amount will your friend have to pay back?With steps pls, thanks!

Answer»

Answer:

principal is $1500

time is 4 MONTHS

rate is 4 ¾ %

so INTEREST is prt/100

=1500×4×4¾/100

= 6000 × 4¾/100= 28,500/100

=$28.5

so the interest is $28.5

now let's see the AMOUNT your friend has to PAY

amount = interest + principal

so = 1500+28.5

= $1528.5

so THEREFORE your friend has to pay you $1528.5

The product of two numbers is 13260.one number is 204 find the sum of the two numbers.

Answer»

Given

\bold{Product \ of \ 2 \ <klux>NUMBERS</klux>} = 13260

\bold{One \ of \ the \ <klux>NUMBER</klux>} = 204

Let the other number be x.

\implies 204x=13260

\implies x = \dfrac{13260}{204}

\implies x = 65

\boxed{\boxed{\bold{Therefore, \ the \ other \ number \ is \ 65}}}}}}

Sum of the numbers

= 65+204

= 269

If 5θ and4θ are acute angles satisfying sin 5θ=cos 4θ then,the value of 2 sinθ- √3 tan3θ is​

Answer»

Question:-

If 5θ and4θ are ACUTE angles satisfying sin 5θ=cos 4θ then,the VALUE of 2 sinθ- √3 tan3θ is

{\pink{\underline{\underline{\bold{Answer:-}}}}}

Given : sin 5θ = cos 4θ  and  5θ and 4θ  are acute angles.

sin 5θ = cos 4θ

cos (90° - 5θ) = cos 4θ  

[cos (90° - θ) = sin θ]

On equating both sides,

(90° - 5θ) =  4θ  

90°  =  5θ +  4θ  

90° = 9θ

θ = 90°/9

θ = 10°  

The value of 2 sin 3θ  - √3 tan 3θ :  

= 2 sin 3 (10°) - √3 tan 3(10°)

= 2 sin 30° - √3 tan 30°

= 2 (½) - √3 (1/√3)

[sin 30° = ½ , tan 30° = 1/√3]

= 1 - 1

= 0  

2 sin 3θ - √3 tan 3θ = 0

Hence, the value of 2 sin 3θ - √3 tan 3θ is 0 .
