(ii) Again,Now,And,Speed-Distance travelledTime takenDistance travelled by train B = 180 kmTime taken by train B = 4 h180 kmSpeed of train B =4h= 45 km/hSo,Thus, the speed of train B is 45 kilometres per hour.-(2)hereas the train B travels a distance of 45 kilometres in one hour. Since the speed of train B is higher,terefore, train B has travelled faster.Sample Problem 3. A car travels 30 km at a uniform speed of 40 km/h and the next 30 km at a uniformeed of 20 km/h. Find its average speed.Solution. (1) First the car travels a distance of 30 kilometres at a speed of 40 kilometres per hour. Let usnd out the time taken by the car to travel this distance.Here,Speed = 40 km/hDistance = 30 kmAnd,Time = ?(To be calculated)DistanceWe know that,SpeedTimeSo,3040 =Time30Time = hours40And,From the above calculations we find that the train A travels a distance of 40 kilometres in one hour​

If P-Q-R, l(PQ)=3√2, l(PR)=5√2 then find l(QR)?

Answer»

SOLUTION

GIVEN

P-Q-R and l(PQ) = 3√2, l(PR) = 5√2

TO DETERMINE

l(QR)

EVALUATION

Here I is REPRESENTING d

Here it is given that : P-Q-R

So Q is the point between P and R

Here it is also given that

l(PQ) = 3√2, l(PR) = 5√2

Hence

\sf{I(QR) =  I(PR) -I(PQ)  \: \: }

\implies \sf{I(QR) =  5 \sqrt{2} -3 \sqrt{2}  \: \: }

\implies \sf{I(QR) =  2 \sqrt{2} \: \: }

FINAL ANSWER

\sf{I(QR) =  2 \sqrt{2} \: \: }

14. In a triangle ABC, AB = 6, BC = 8 andAC = 10. A perpendicular dropped from B.meets in side AC at D. A circle of radiusBD (with center B) is drawn. If the circlecuts AB and BC at P and Q, respectively,then AP:QC is equal to:(a) 1:1(b) 3:2(c) 4:1(d) 3:8

Answer»

Answer:

Option D,

3:8

Step-by-step explanation:

Area of TRIANGLE ABC = 1/2 x 6 x 8 = 24 sq.units

Area of triangle ABD = 1/2 x 10 x BD = 24

BD = 4.8

AP= 6 - 4.8 = 1.2

QC = 8 - 4.8 =3.2

AP/QC = 1.2/3.2 = 3/8

answer: 3:8

Answer»

ANSWER:

Step-by-step EXPLANATION:

30.

In the given figure, ABCD is a parallelogram. If ∠B = 100°, then find the value of ∠A +∠C.

Answer»

The co-interior ANGLES are always 180° given angle B = 100

angle B + angle C = 180°

so ,180 - 100 = 80 ° angle C = 80°

The OPPOSITE angles of a PARALLELOGRAM are equal

i.e,

angle A = angle C = 80°

angle B = angle D = 100°

80° + 80° = 160°

Hence, the answer is 160°

Solution of the system of linear equations 3x - 2y = 0, 2x + y = 7 is

Answer»

ANSWER:

3x - 2y = 0

= 3x = 2y

= x =  \frac{2}{3} y

2x + y = 7

= 2( \frac{2}{3} y) + y = 7

= \frac{4y}{3}  + y = 7

= \frac{4y + 3y}{3}  = 7

= 7y = 7 \times 3

= y =  \frac{21}{7}

y = 3

x =  \frac{2}{3} y =  \frac{2}{3}  \times 3 = 2

So, \: x = 2 \: and \: y = 3

The product of two numbers is 210 and their HCF is 1.what is their LCM

Answer»

The formula for finding LCM in this QUESTION is

=> 1st no. * 2nd no. = LCM * HCF

=> 210 (Given in question) = LCM * 1 (Given in question)

=> LCM = 210/1 (TRANSPOSED 1 from LHS)

=> LCM = 210  

In other words, whenever HCF of 2 numbers is 1, then their product will be the LCM.
