A garrison of 120 men has provision for 30 days. At the end of five days, five moremen joined them. How many days can they sustain on the remaining provision?​

Answer»

we KNOW that no. of days is inversely propotional to the provision for MEN

So for 120 men the provision WOULD LAST for 30days. (given) 

Therefore, the provision for 1 men would sustain for. 120 *30 = 3600 days. 

Let after the joining of 5 men (after 5 days) the no of more days the provision would last is x days 

A.t.q 120*30 = 120*5+125*x 

(120*30) - (120*5)= 125x 

120(30-5)=125x 

120 * 25 = 125x 

120 = 5x 

x=120/5 

x= 24 

so the provision would remain for more 24 days.

May u plzz solve it or give me clue for solving it ​

Answer»

For infinite no of solutions

Both EQUATION should be same then only they will have infinite no of points.coinciding

So coefficients PROPORTIONAL

(2M-1)/3 = 3/(n-1) = 5/2

2m-1)/3 = 5/2

2m -1 = 15/2

2m = 15/2. + 1 = 17/2

m = 17/4

3/(n-1) = 5/2

6/5 = ( n-1)

n = 6/5 +1 = 11/5

5/x+1/y = 2; 6/x-3/y = 1 x is not equal to 0, y is not equal to 0solve the above pair

Answer»

Answer:

LET 1/x be a and 1/y be b .

So 5a+b=2 ...(1) and

6a-3b=1...(2) Multiply (1) by 3 and add it to (2) equation , 15a+3b+6a-3b = 6+1=7 => 21A = 7 => a =1/3 and Substitute a=1/3 in equation (1), 5a+b=2 => 5(1/3)+b=2 => b=2 -5/3 => b= 1/3 Hence 1/x =1/y =1/3 => x=y=3 . The solutions to these EQUATIONS are x=3 and y=3. Hope it HELPS you. Mark me as Brainliest.

A shopkeeper sold mathematics books for Rs 108 on Monday and Rs 84 on Tuesday. What canBe the maximum price of each book?​plz plz plz answer me fast

Answer»

The shopkeeper SOLD math BOOK for Rs 120 on Monday.

And the shopkeeper sold math book for Rs 64 on Tuesday.

We will calculate the maximum price by using LCM

The maximum price of the book is lcm(120,64)

120= 3 × 2 × 2 × 5 × 2

64= 2 × 2 × 2 × 2 × 2 × 2

LCM = 8 × 120 = 960

Therefore,

Answer: The maximum price of each book is Rs.960.

2^16 -1 divisible by......17full process shortcut

Answer»

Answer:

{2}^{16}  - 1

can be expressed as

( {2}^{8}  - 1) \times (2^{8} + 1)

As

{x}^{2}  -  {y}^{2}  = (x + y) \times (x - y)

So we can now express

{2}^{8}  - 1 = ( {2}^{4} + 1) \times ( {2}^{4} - 1)

We know that 2^4 +1 is equal to 17 So we can write

{2}^{16}  - 1 = ( {2}^{8}  - 1) \times 17 \times ( {2}^{4 } - 1)

Hence it is divisible by 17. HOPE it helps you. MARK me as BRAINLIEST if you think I am worth of it.

If x is equal to 9 + 4 under root 5 then find the value of x minus one upon x

Answer»

Step-by-step EXPLANATION:

X=9+4√5

1/x=1/9+4√5

Rationalising

1/x=1(9-4√5)/(9+4√5)(9-4√5)

=9-4√5/81-80

=9-4√5/1

1/x=9-4√5

now,

x - 1/x= 9+4√5-(9-4√5)

x - 1/x= 9+4√5-9+4√5

x - 1/x=8√5

2) x² + 2x - 5 = 0457272 +9y + 10 = 0 |​

Answer»

x² + 2X - 5 = 0

So, we have to find to it's zeroes by USING completing Square method.

x² + 2x - 5 = 0

we can write 2x = 2(x)(1)

x² + (2)(x)(1) + [ 1² - 1²] - 5 = 0

(x + 1)² - 1 - 5 = 0

[(x² + 2x + 1) = (x + 1)² , where, (a² + b² + 2ac = (a + b)²]

so,

(x + 1)² = 6

[taking Square Root both SIDE]

(x + 1) = ±√6

now there is TWO SITUATION

( 1 ) we have to take (+ve) sign.

So, answeer will be.

(x + 1) = √6

x = (√6 - 1)

( 2 ) we have to take (+ve) sign.

So, answeer will be.

(x + 1) = -√6

x = -(√6 + 1)

Express (1+7i) in Eulerian form.​

Answer»

Answer:

The expression is euler formula is given as √50 ( cos(81. 86) + i son (81.86).

Step-by-step explanation:

To solve:

Express (1+7i) in EULERIAN form.​

According to Eulerian formula,

a+bi = rcos θ + r i sin θ

1+7i = r cos θ + r i sinθ

Thus rcos θ = 1

r sinθ = 7

r = √(1) ^2+ (7) ^

r = √ 1+49

r = √50

rcos θ = 1

Hence,

cos θ = 1/r

= 1/√50

Hence, θ = 81.86

Also,

r sinθ = 7

Hence,

sinθ = 7/r

sinθ = 7/√50

Hence, θ = 81.86

Euler form is EXPRESSED as

a+bi = rcos θ + r i sin θ

1+7i = r (cos θ + i sin θ)

= √50 ( cos(81. 86) + i son (81.86)

Hence, the expression is euler formula is given as √50 ( cos(81. 86) + i son (81.86)
