Answer» Step-by-step explanation: Given A rectangle has the same area as another, WHOSE length is 6 m more and breadth is 4 m LESS. It has also the same area as the third, whose length is 8 m more and breadth 5 cm less. Find the length and breadth of the original rectangle Let the length and breadth of the original rectangle be l and b respectively. ACCORDING to question rectangle with 6m is more so it will be l + 6 and breadth is 4 m less, so b – 4 Now area of rectangle is l X b. so we can write as l x b = (l + 6)(b – 4) = lb + 6b – 4l – 24 We get -4l + 6b – 24 = 0 Or 4l – 6b + 24 = 0 Again according to question area of original rectangle is equal to area of third rectangle with length 8 m more and breadth 5 m less Now the equation will be l x b = (l + 8)(b – 5) l x b = lb + 8b – 5l – 40 = lb – 5l + 8b – 40 We get -5l + 8b – 40 = 0 Or 5l – 8b + 40 = 0 Now we have simultaneous equations to solve, 4l – 6b + 24 = 0 multiply by 5 5l – 8b + 40 = 0 multiply by 4 We get 20l – 30b + 120 = 0 20l – 32b + 160 = 0 2b = 40 So b = 20 m Substituting b = 20 we get 4l – 6b + 24 = 0 4l – 6(20) + 24 = 0 4l – 120 + 24 = 0 4l – 96 = 0 4l = 96 So l = 24 m So length and breadth of rectangle will be 24 m and 20 m Read more on Brainly.in - brainly.in/question/13844157#readmore

Ii) A rectangle has the same area as anotherhas the same area as another, whose length is 6 m more and breadthcss. It has also the same area as the third, whose length is 8 m more andbreadth 5 m less. Find the length and breadth of the original rectangle.

Answer»

Step-by-step explanation:

Given A rectangle has the same area as another, WHOSE length is 6 m more and breadth is 4 m LESS. It has also the same area as the third, whose length is 8 m more and breadth 5 cm less. Find the length and breadth of the original rectangle

Let the length and breadth of the original rectangle be l and b respectively.

ACCORDING to question rectangle with 6m is more so it will be l + 6 and breadth is 4 m less, so b – 4

Now area of rectangle is l X b. so we can write as

l x b = (l + 6)(b – 4)

= lb + 6b – 4l – 24

We get -4l + 6b – 24 = 0

Or 4l – 6b + 24 = 0

Again according to question area of original rectangle is equal to area of third rectangle with length 8 m more and breadth 5 m less

Now the equation will be

l x b = (l + 8)(b – 5)

l x b = lb + 8b – 5l – 40

= lb – 5l + 8b – 40

We get -5l + 8b – 40 = 0

Or 5l – 8b + 40 = 0

Now we have simultaneous equations to solve,

4l – 6b + 24 = 0 multiply by 5

5l – 8b + 40 = 0 multiply by 4

We get

20l – 30b + 120 = 0

20l – 32b + 160 = 0

2b = 40

So b = 20 m

Substituting b = 20 we get

4l – 6b + 24 = 0

4l – 6(20) + 24 = 0

4l – 120 + 24 = 0

4l – 96 = 0

4l = 96

So l = 24 m

So length and breadth of rectangle will be 24 m and 20 m

Let the point be P(x,0) A = (7,6) B = (-3,4) AP = BP AP² = BP² (x-7)² + (0-6)² = (x+3)² + (0-4)² Solving, we get x²+49-14x+36 = x²+9+6x+16 49+36-9-16 = 6x+14x 60 = 20x x= 3 Therefore point is (3,0) ****** Hope it HELPS.

17.

What points on the x-axis is equidistance from (7,6) and (-3,4)?

Answer»

<P>Answer:

(3,0)

Step-by-step explanation:

If the point is on x axis, y- coordinate is zero.

Let the point be P(x,0)

A = (7,6)

B = (-3,4)

AP = BP

AP² = BP²

(x-7)² + (0-6)² = (x+3)² + (0-4)²

Solving, we get

x²+49-14x+36 = x²+9+6x+16

49+36-9-16 = 6x+14x

60 = 20x

x= 3

Therefore point is (3,0)

The marked price of a laptop is Rs. 12000. In aclearance sale it is sold at a discount of 15%, incurringa loss of 4%. What is the cost price of the laptop?(a) Rs. 10200(b) Rs. 10625(c) Rs. 11200(d) Rs. 10275

Answer»

$i ) Marked \:price (m.p) = Rs\:12000,\\discount (d) = 15\% ,\\Let \: selling \:price = s.p$

$\boxed { \pink { selling \:price = m.p\Big( \frac{100-d}{100}\Big) }}$

$s.p = 12000 \Big( \frac{100-15}{100}\Big)\\= 12000 \times \frac{85}{100} \\= 120 \times 85 \\= Rs\:10200 \: --(1)$

$ii ) Let \: Cost \: price (c.p) = Rs \:x ,\\Loss(l) = 4\% ,$

$\boxed { \pink { selling \:price = c.p\Big( \frac{100-l}{100}\Big) }}$

$Selling \:price = x\Big( \frac{100- 4}{100}\Big) \\= x\times \frac{96}{100} \:--(2)$

$(2 )= (1)$

$x\times \frac{96}{100} = 10200$

$\implies x = 10200 \times \frac{100}{96} \\= Rs \:10625$

$Cost \:price \: of \:the \: Laptop (c.p) = Rs \:10625$

Prove that√2 is irraational

Answer»

<P>Answer:

proof = let us assume that √2 is rational no.

Step-by-step explanation:

since rational no √2= p/q ; hcf(p,q) = 1 ; q not EQAL to 0 and p, q belongs to integers

i. e. p/q = √2

s. o. b. s

p2/q2= 2

p2=2q2

here 2 divides p2

2 divides p......... 1

since 2 divides p

let p be 2m where m is some integer

from above 2m = q2

s. o. b. s

q2= 4m2

q2= 2m2

here 2 divides q2

2 divides q

since here 2 divides both q and p

hcf(p,q)=2

but above hcf of p, q is 1

this contradiction arises if our assumption is wrong

therefore our assumption is wrong

and hence √2 is irrational

Rahi is 19 years younger than his cousin. After five years, their ages will be in the ratio 2:3. Find their present ages.

Answer»

ANSWER:

Lets TAKE Rahi cousin's age be x yrs

Therefore Raju 's age = x - 19

Ratio between Raju and his cousin = 2 : 3 or 2/3

Hence (x - 19) + 5/x + 5 = 2/3

= 5 + x - 5 + 19/x + 5 = 2/3

= 5 + x - 14/x + 5 = 2/3

= 15 + 3X - 42/2x + 10

= - 37 + 3x = 2x+10

= - 37 - 10 = 2x - 3x

= - 47 = - x

= 47 = x = His cousin age after 5 yrs=47 + 5 = 52yrs

= His age = 52 - 19 = 33yrs
