5.	In a ΔABC, if 2∠A = 3∠B = 6∠C. Determine ∠A, ∠B and ∠C?
Answer» DEGREE is not written in calculation. Answer: 90° , 60° and 30° Step-by-step explanation: Here, 2∠A = 3∠B = 6∠C. ⇒ 2∠A = 3∠B ; 2∠A = 6∠C ⇒ (2/3)∠A = B ; (2/6)∠A = ∠C ⇒ (2/3)∠A = B ; (1/3)∠A = ∠C In a triangle : Sum of all angles is 180° ⇒ ∠A + ∠B + ∠C = 180° ⇒ ∠A + (2/3)∠A + (1/3)∠A = 180 ⇒ ( 3∠A + 2∠A +∠A ) / 3 = 180 ⇒ 6∠A / 3 = 180 ⇒ 2∠A = 180 ⇒ ∠A = 180 / 2 = 90 HENCE, ∠B = (2/3)∠A = (2/3) 90 = 60 ∠C = (1/3)∠A = (1/3)90 = 30 Hence the REQUIRED angles are 90° , 60° and 30°. ∠A = 90° ; ∠B = 60° ; ∠C = 30°

5.

In a ΔABC, if 2∠A = 3∠B = 6∠C. Determine ∠A, ∠B and ∠C?

Answer»

DEGREE is not written in calculation.

Answer:

90° , 60° and 30°

Step-by-step explanation:

Here,

2∠A = 3∠B = 6∠C.

⇒ 2∠A = 3∠B ; 2∠A = 6∠C

⇒ (2/3)∠A = B ; (2/6)∠A = ∠C

⇒ (2/3)∠A = B ; (1/3)∠A = ∠C

In a triangle :

Sum of all angles is 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A + (2/3)∠A + (1/3)∠A = 180

⇒ ( 3∠A + 2∠A +∠A ) / 3 = 180

⇒ 6∠A / 3 = 180

⇒ 2∠A = 180

⇒ ∠A = 180 / 2 = 90

HENCE,

∠B = (2/3)∠A

= (2/3) 90

= 60

∠C = (1/3)∠A

= (1/3)90

= 30

Hence the REQUIRED angles are 90° , 60° and 30°.

∠A = 90° ; ∠B = 60° ; ∠C = 30°

find the value of k for which the pair of linear equation 2 X + 3 Y equal to 7 and 4 x + a y equal to 14

Answer»

Answer:

consider equation (1)

2X + 3y = 7

MULTIPLE whole equation with 2

( 2x + 3y = 7 ) * 2

==> 4x + 6Y = 14

now

4x + ay = 14 ............ (1)

4x + 6y = 14 ............(2)

substracting (2) with (1)

we get

ay - 6y = 0

==> ay = 6y

y on both sides get cancel

==> a = 6

8.	A dealer supplies you the following information with regard to a product dealt in by him.Annual demand = 5000 units;Buying Cost = . 250.00 per orderInventory carrying cost = 30% per yearPrice = . 100 per unitThe dealer is considering the possibility of allowing Home back orders to occur for theproduct. He has estimated that the annual cost of back ordering (allowing shortages) the product will be Rs. 10.00 per unit.(i) What should be the optimum number of units of the product he should buy in one lot?(ii) What quantity of the product should he allow to be back-ordered?(iii) How much additional cost will he have to incur on Inventory if he does not permit back-ordering?
Answer» Answer: Let the initial velocity of the body be u m/s; and the constsnt acceleration be a m/s². Then displacemet (DISTANCE covered) of the body after t SECOND is given by s = u t + ½ a t² ———————————-(1) The body covers 20 m in 2s and 80 m in 4 s. 20 = u×2 + ½ a 2²; => 20 = 2 u + 2 a u + a = 10 —————————————(2) 80 = u×4 + ½ a 4²; => 80 = 4 u + 8 a; this gives, u + 2 a = 20 ——————————————(3) Solving (2) and (3) for u and a we get u = 0 m/s and a = 10 m/s² ————————(4) To OBTAIN the distance covered in the next 4s we need to find the velocity at the beginning of this interval using, v = u + a t => v = 0

Answer»

Answer:

Let the initial velocity of the body be u m/s; and the constsnt acceleration be a m/s². Then displacemet (DISTANCE covered) of the body after t SECOND is given by

s = u t + ½ a t² ———————————-(1)

The body covers 20 m in 2s and 80 m in 4 s.

20 = u×2 + ½ a 2²; => 20 = 2 u + 2 a

u + a = 10 —————————————(2)

80 = u×4 + ½ a 4²; => 80 = 4 u + 8 a; this gives,

u + 2 a = 20 ——————————————(3)

Solving (2) and (3) for u and a we get

u = 0 m/s and a = 10 m/s² ————————(4)

To OBTAIN the distance covered in the next 4s we need to find the velocity at the beginning of this interval using,

v = u + a t => v = 0

42.	A deer sees a tiger 100m away and starts running away from it at the speed of 15 mps.The tiger sees the deer 5 seconds later and pursues it at the speed of 40 mps. How muchlater will the tiger catch the deer?
Answer» Step-by-step explanation: Spee of deer = 15m/s Time =5 sec DISTANCE traveled by deer in 5 sec when tiger do not see the deer Distance = speed × time = 15 × 5 =75 m Now to caught the deer, the tiger has to cover extra 75 m as it starts to run 5sec LATE till that the deer has been COVERED 75M of extra distance. So the total distance which tiger has to cover =100 +75=175 m Speed of tiger = 40m/s Time taken = Distance /speed = 175/40 = 4.3 sec Tiger will take 4.3 sec to caught the deer

A deer sees a tiger 100m away and starts running away from it at the speed of 15 mps.The tiger sees the deer 5 seconds later and pursues it at the speed of 40 mps. How muchlater will the tiger catch the deer?

Answer»

Step-by-step explanation:

Spee of deer = 15m/s

Time =5 sec

DISTANCE traveled by deer in 5 sec when tiger do not see the deer

Distance = speed × time

= 15 × 5

=75 m

Now to caught the deer, the tiger has to cover extra 75 m as it starts to run 5sec LATE till that

the deer has been COVERED 75M of extra distance.

So the total distance which tiger has to cover =100 +75=175 m

Speed of tiger = 40m/s

Time taken = Distance /speed

= 175/40

= 4.3 sec

Tiger will take 4.3 sec to caught the deer

A deer sees a tiger 100m away and starts running away from it at the speed of 15 mps.The tiger sees the deer 5 seconds later and pursues it at the speed of 40 mps. How muchlater will the tiger catch the deer?​

Spee of deer = 15m/s

Time =5 sec

DISTANCE traveled by deer in 5 sec when tiger do not see the deer

Distance = speed × time

= 15 × 5

=75 m

Now to caught the deer, the tiger has to cover extra 75 m as it starts to run 5sec LATE till that

the deer has been COVERED 75M of extra distance.

So the total distance which tiger has to cover =100 +75=175 m

Speed of tiger = 40m/s

Time taken = Distance /speed

= 175/40

= 4.3 sec

Tiger will take 4.3 sec to caught the deer
