4.	A motorboat whose speed in still water is 18 km/h, takes 1 hour more to go 24 km upstreamthan to return downstream to the same spot. Find the speed of the stream.
Answer» Answer: s=6km/hr Step-by-step EXPLANATION: Given: Speed of BOAT in STILL water = 18km/hr Let speed of the stream = s Speed of boat upstream = Speed of boat in still water - speed of stream = 18−s Speed of boat down stream = Speed of boat in still water + speed of stream = 18+s Time TAKEN for upstream = Time taken to cover DOWNSTREAM + 1 24(18+s)=24(18−s)+(18−s)(18+s) ⇒s 2 +48s−324=0 ⇒s 2 +54s−6s−324=0 ⇒(s+54)(s−6)=0 ⇒s=6,−54 ⇒s  =−54 Thus, s=6km/hr, Speed of steam cannot be negative.

4.

A motorboat whose speed in still water is 18 km/h, takes 1 hour more to go 24 km upstreamthan to return downstream to the same spot. Find the speed of the stream.

Answer»

Answer:

s=6km/hr

Step-by-step EXPLANATION:

Given:

Speed of BOAT in STILL water = 18km/hr

Let speed of the stream = s

Speed of boat upstream = Speed of boat in still water - speed of stream = 18−s

Speed of boat down stream = Speed of boat in still water + speed of stream = 18+s

Time TAKEN for upstream = Time taken to cover DOWNSTREAM + 1

24(18+s)=24(18−s)+(18−s)(18+s)

⇒s

2

+48s−324=0

⇒s

2

+54s−6s−324=0

⇒(s+54)(s−6)=0

⇒s=6,−54

⇒s



=−54

Thus, s=6km/hr, Speed of steam cannot be negative.

Answer» Step-by-step explanation: Length of RECTANGLE is reduced by 5 units and its breadth is increased by 3 units and the AREA of rectangle is reduced by 8 sq. units (L−5)(W+3)=LW−8 LW+3L−5W−15=LW−8 3L−5W=7 __(1) Length is reduced by 3 units and breadth is increased by 2 units, then the area of Rectangle will be 67 sq. units increased (L−3)(W+2)=LW+67 LW+2L−3W−6=LW+67 2L−3W=73 __(2) Solving (1)×2 by (2)×3 2(3L−5W=7)→6L−10W=14 3(2L−3W=73)→6L−9W=219 −W=−205 W=205 W = 205 in eq (1). 3L−5(205)=7 3L=7+1025 3L=1032→L= 3 1032 L=344 please follow me and mark me as a brainlinst

Not lactorable.5. If a square pool is to be made a rectangle such that the length is increased by 6 and the widthis decreased by 6 units, what will happen to its area?a. The area will increase by 12.b. The area will decrease by 12.c. The area will increase by 36.d. The area will decrease by 36.

Answer»

Step-by-step explanation:

Length of RECTANGLE is reduced by 5 units and

its breadth is increased by 3 units and the

AREA of rectangle is reduced by 8 sq. units

(L−5)(W+3)=LW−8

LW+3L−5W−15=LW−8

3L−5W=7 __(1)

Length is reduced by 3 units and breadth is increased

by 2 units, then the area of Rectangle will be

67 sq. units increased

(L−3)(W+2)=LW+67

LW+2L−3W−6=LW+67

2L−3W=73 __(2)

Solving (1)×2 by (2)×3

2(3L−5W=7)→6L−10W=14

3(2L−3W=73)→6L−9W=219

−W=−205

W=205

W = 205 in eq (1).

3L−5(205)=7

3L=7+1025

3L=1032→L=

1032

L=344

27.

What is the volume of mercury in cm3 if mass of mercury is 1 kg, and density is 13.6g/cm3

Answer»

ANSWER:

density = mass/volume

density = 13.6 or 136/10 g/cm³

mass = 1KG or 1000g

therefore, LET volume be = x cm³

so, the equation will be :-

=> 136/10 = 1000/x

=> 136x = 10000

=> x = 10000/136

=> x = 73.53 cm³ ( approx )

Answer» Answer: $\huge\pink{\fbox{\tt{࿐verified \: answer࿐}}}$ If TWO squares have EQUAL areas, they will also have sides of the same length. But although "equal areas mean equal sides" is true for squares, it is not true for most GEOMETRIC figures. ... Two geometric figures are called congruent if they have the same SIZE and the same shape.

Prove that cot θ-cosθ/cotθ+cosθ=cosecθ-1/cosecθ+1

Answer»

ANSWER:

Step-by-step EXPLANATION:

$\Large{\underline{\rm{Given:}}}$

$\sf \dfrac{cot\theta-<klux>COS</klux>\theta}{cot\theta+cos\theta} =\dfrac{cosec\theta-1}{cosec\theta+1}$

$\Large{\underline{\rm{To\:Prove:}}}$

LHS = RHS

$\Large{\underline{\rm{Identities\:used:}}}$

$\sf cot\theta=\dfrac{cos\theta}{sin\theta}$

$\sf \dfrac{1}{sin\theta} =cosec\theta$

$\Large{\underline{\rm{Proof:}}}$

➞Here we have to the prove that the LHS of the equation = RHS.

➞ Taking the LHS of the equation,

$\sf \dfrac{cot\theta-cos\theta}{cot\theta+cos\theta}$

➞ Using identities,

$\sf \implies \dfrac{\dfrac{cos\theta}{sin\theta}-cos\theta }{\dfrac{cos\theta}{sin\theta} +cos\theta}$

➞ Taking cos θ COMMON from both numerator and denominator,

$\sf \implies \dfrac{cos\theta(\dfrac{1}{sin\theta}-1) }{cos\theta(\dfrac{1}{sin\theta} +1)}$

➞ Cancelling cos θ on both numerator and denominator,

$\sf \implies \dfrac{(\dfrac{1}{sin\theta}-1) }{(\dfrac{1}{sin\theta} +1)}$

➞ Using SUITABLE identities,

$\sf \implies \dfrac{cosec\: \theta -1}{cosec\: \theta+1}$

$\implies \sf RHS$

➞ Hence proved.

$\Large{\underline{\rm{More\:Identities:}}}$

$\sf tan\theta=\dfrac{sin\theta}{cos\theta}$

$\sf \dfrac{1}{cos\theta} =sec\theta$

$\sf \dfrac{1}{tan\theta} =cot\theta$
