6.	Ratio of milk and water in two vessels a and b is 3:5 and 1:3 respectively . In wjat ratio they must be mixed so resultant solution may contain half milk and half water?
Answer» Answer: 2:1 Step-by-step EXPLANATION: Vessel A MILK & water= 3/8 & 5/8 Vessel B milk & water= 1/4 & 3/4 Now milk & water mixed in we get half milk and half water . Then, 3x/8+ y/4= 1/2..............(1) 5x/8 + 3y/4= 1/2 .............(2) solving both (3x+2y)= 4..............(1) 5x+6y= 4................(2) multiply EQUATION 1 by 3 9x+6y=12 5x+6y=4 now SUBTRACT (2) from equation (1) 4x=8 x=2 then y = 1 Therefore ratio is 2:1

6.

Ratio of milk and water in two vessels a and b is 3:5 and 1:3 respectively . In wjat ratio they must be mixed so resultant solution may contain half milk and half water?

Answer»

Answer:

2:1

Step-by-step EXPLANATION:

Vessel A MILK & water= 3/8 & 5/8

Vessel B milk & water= 1/4 & 3/4

Now milk & water mixed in we get half milk and half water .

Then,

3x/8+ y/4= 1/2..............(1)

5x/8 + 3y/4= 1/2 .............(2)

solving both

(3x+2y)= 4..............(1)

5x+6y= 4................(2)

multiply EQUATION 1 by 3

9x+6y=12

5x+6y=4

now SUBTRACT (2) from equation (1)

4x=8

x=2

then y = 1

Therefore ratio is 2:1

Sum of first p, q, r terms of an A. P are a,b,c respectively.SHOW THAT :❌NO SPAM ❌BEST ANSWER WILL BE MARKED AS BRAINLIEST! ✔️

Answer»

Note: Sum of n terms = (n/2)[2a + (n - 1) * d].

Let the first term be A and the common difference be d.

(i)

GIVEN sum of p terms = a.

⇒ (p/2)[2A + (p - 1) * d] = a

⇒ (a/p) = (1/2)[2A + (p - 1) * d]

(ii)

Given sum of Q terms is b.

⇒ (q/2) = 2A + (q - 1) * d = b

⇒ (q/p) = (1/2)[2A + (q - 1) * d]

(III)

Given sum of r terms of an AP is c.

⇒ (r/2)[2A + (r - 1) * d] = c

⇒ (r/c) = (1/2)[2A + (r - 1) * d]

(IV)

On subtracting (ii) from (i), we get

$=>\frac{a}{p} -\frac{b}{q} =\frac{1}{2} (p - 1)d -(q - 1)d$

$=>\frac{a}{p}-\frac{b}{q}=\frac{1}{2}[(p - q) *d]$

$=> p-q=\frac{2}{d}[\frac{a}{p}-\frac{b}{q}]$

(V)

On subtracting (iii) from (ii), we get

$=>\frac{b}{q}-\frac{c}{r}=\frac{1}{2}[(q-1)d-(r-1)d]$

$=>\frac{b}{q}-\frac{c}{r}=\frac{1}{2}(q-r)d$

$=>q-r=\frac{2}{d}[ \frac{b}{q}-\frac{c}{r}]$

(vi)

on subtracting (iii) from (i), we get

$=>\frac{c}{r}-\frac{a}{p}=\frac{1}{2}(r-p)d$

$=>r-p =\frac{2}{d}[ \frac{c}{r}- \frac{a}{p}]$

Now,

Given Equation is (a/p)(q - r) + (b/q)(r - p) + (c/r)(p - q) = 0

$=>\frac{a}{q}[\frac{2}{d}(\frac{b}{q}- \frac{c}{r})]+\frac{b}{q}[\frac{2}{d}(\frac{c}{r}-\frac{a}{p})]+\frac{c}{r}[\frac{2}{d}( \frac{a}{p}-\frac{b}{q})]$

$=>\frac{2}{d}[\frac{ab}{pq}- \frac{ac}{pr}+\frac{bc}{qr}-\frac{ab}{pq}+\frac{ac}{pr}-\frac{bc}{qr}]$

$=>0.$

15.

Write the coordinates of the vertices of the geometrical figures and find its area.

Answer»

solution:

1. co-ordinate of square

A(2,-1), B(7,-1), C(7,-4) and D(2,-4)

Area = length * Breadth

Length = 5 units

Breadth = 3 units

**Area = 5*3 = 15 unit²**

----------------------

Coordinate of second ||gm

S(2,-2), P(1,-4), O(4,-4) and R(6,-2)

Area OG ||gm = BASE * Altitude

Base = 4 units

Altitude = 2 units

**∴Area = 4*2 = 8units²**

hey FRIEND!

here's your answer:

H.C.F of 1168 is 73

H.C.F of 1095 is 73.

EXPLAINATION:

for first CASE H.C.F of 1168:

1168=1095*1+73. (by EUCLID's division lemma)

1095=73*15+0.

so Here, remainder is 0 THEREFORE H.C.F is 73.

for second case H.C.F of 1095:

1095=1022*1+73 (by Euclid's division lemma)

1022=73*14+0

so Here, remainder is 0 therefore H.C.F is 73.

Megha purchased 10 metres of curtain material. She stitched 3 curtains if lengths 2 1/4 meter , 1 1/2 meter , and 2 1/3 meter respectively. How much material was left unstitched?

Answer»

curtain purchased = 10 m

stitched = 2 1/4 + 1 1/2 + 2 1/3

=> 9/4 + 3/2 + 7/3

=> 73/12

CLOTH LEFT UNSTICHED = 10 - 73/12
