(2) By adding both the EQUATIONS Area of △ SPQ + Area of △ SRQ = ½ (Area of parallelogram ABQS + Area of parallelogram SQCD) So we get Area of parallelogram PQRS = ½ (Area of parallelogram ABCD) Therefore, it is proved that ar (\|\|gm PQRS) = ½ × ar (\|\|gm ABCD).

P, Q, R, S are respectively the midpoints of thesides AB, BC, CD and DA of ||gm ABCD. Showthat PQRS is a parallelogram and also show thatar (Ilgm PQRS) = 1/2 xar(||gm ABCD).

Answer»

Answer:

We know that

Area of parallelogram PQRS = ½

(Area of parallelogram ABCD)

Construct diagonals AC, BD and SQ

From the figure we know that S and R are the MIDPOINTS of AD and CD

Consider △ ADC

Using the midpoint theorem

SR || AC

From the figure we know that P and Q are the midpoints of AB and BC

Consider △ ABC

Using the midpoint theorem

PQ || AC

It can be written as

PQ || AC || SR

So we get

PQ || SR

In the same way we get

SP || RQ

Consider △ ABD

We know that O is the midpoint of AC and S is the midpoint of AD

Using the midpoint theorem

OS || AB

Consider △ ABC

Using the midpoint theorem

OQ || AB

It can be written as

SQ || AB

We know that ABQS is a parallelogram

We get

Area of △ SPQ = ½

(Area of parallelogram ABQS) ……. (1)

In the same way we get

Area of △ SRQ = ½

(Area of parallelogram SQCD) …….. (2)

By adding both the EQUATIONS

Area of △ SPQ + Area of △ SRQ = ½

(Area of parallelogram ABQS + Area of parallelogram SQCD)

So we get

Area of parallelogram PQRS = ½

(Area of parallelogram ABCD)

Therefore, it is proved that ar (||gm PQRS) = ½ × ar (||gm ABCD).

Answer» The average speed of its entire journey is 81.8 KM/h Step-by-step explanation: GIVEN A VEHICLE travels the first 40 km of its journey at an average speed of 60 km/h The REMAINING 50km at an average speed of 100 km/h ___________________________ TO FIND The average speed of its entire journey ___________________________ We know that, Speed = Distance / Time Distance = Speed × Time Time = Distance / Speed ___________________________ We know that, A vehicle travels the first 40 km of its journey at an average speed of 60 km/h Distance = 40 km Speed = 60 km/h Time = ? We know that, Time = Distance / Speed Time = 40 / 60 Time = 0.6 Time = 0.6 hours ___________________________ We know that, The remaining 50km at an average speed of 100 km/h Distance = 50 km Speed = 100 km/h Time = ? We know that, Time = Distance / Speed Time = 50 / 100 Time = 0.5 Time = 0.5 hours ___________________________ Now Let's find the average speed of entire journey We know that, Distance = 40 km + 50 km Distance = 90 km Time = 0.6 hours + 0.5 hours Time = 1.1 hours Speed = ? We know that, Speed = Distance / Time Speed = 90 / 1.1 Speed = 81.8 Speed = 81.8 km/h The average speed of its entire journey is 81.8 km/h

A vehicle travels the first 40 km of its journey at an average speed of 60km/h and the remaining 50km at an average speed of 100 km/h. Find theaverage speed of its entire journey.MY ANSWER IS 75 15/7 I THINK ITS WRONGHELP ME

Answer»

The average speed of its entire journey is 81.8 KM/h

Step-by-step explanation:

GIVEN

A VEHICLE travels the first 40 km of its journey at an average speed of 60 km/h

The REMAINING 50km at an average speed of 100 km/h

___________________________

TO FIND

The average speed of its entire journey

___________________________

We know that,

Speed = Distance / Time

Distance = Speed × Time

Time = Distance / Speed

___________________________

We know that,

A vehicle travels the first 40 km of its journey at an average speed of 60 km/h

Distance = 40 km

Speed = 60 km/h

Time = ?

We know that,

Time = Distance / Speed

Time = 40 / 60

Time = 0.6

Time = 0.6 hours

___________________________

We know that,

The remaining 50km at an average speed of 100 km/h

Distance = 50 km

Speed = 100 km/h

Time = ?

We know that,

Time = Distance / Speed

Time = 50 / 100

Time = 0.5

Time = 0.5 hours

___________________________

Now

Let's find the average speed of entire journey

We know that,

Distance = 40 km + 50 km

Distance = 90 km

Time = 0.6 hours + 0.5 hours

Time = 1.1 hours

Speed = ?

We know that,

Speed = Distance / Time

Speed = 90 / 1.1

Speed = 81.8

Speed = 81.8 km/h

The average speed of its entire journey is 81.8 km/h

39.	the length and breadth of a rectangle are in the ratio of 2 : 1 if its breadth is 200m then find its perimeter
Answer» Answer :- Perimeter of RECTANGLE = 1200 m. Explanation :- GIVEN : Length and Breadth are in ratio 2:1. Breadth = 200m. To Find : Perimeter of Rectangle. Solution : Let the dimensions of Rectangle be 2X and x. It is Given that, Breadth of Rectangle = 200m. So, Breadth = x = 200m. And, Length = 2x = 400m. Now, Calculating Perimeter. ➞ Perimeter of Rectangle = 2(L + b). ➞ Perimeter of Rectangle = 2(400 + 200). ➞ Perimeter of Rectangle = 2(600). ➞ Perimeter of Rectangle = 1200m. Therefore, Perimeter of Rectangle = 1200 m.

39.

the length and breadth of a rectangle are in the ratio of 2 : 1 if its breadth is 200m then find its perimeter

Answer»

Answer :-

Perimeter of RECTANGLE = 1200 m.

Explanation :-

GIVEN :

Length and Breadth are in ratio 2:1.
Breadth = 200m.

To Find :

Perimeter of Rectangle.

Solution :

Let the dimensions of Rectangle be 2X and x.

It is Given that,

Breadth of Rectangle = 200m.

So,

Breadth = x = 200m.

And,

Length = 2x = 400m.

Now, Calculating Perimeter.

➞ Perimeter of Rectangle = 2(L + b).

➞ Perimeter of Rectangle = 2(400 + 200).

➞ Perimeter of Rectangle = 2(600).

➞ Perimeter of Rectangle = 1200m.

Therefore, Perimeter of Rectangle = 1200 m.

Answer» CONSIDER r and R as the RADII of two spheres We know that 4πr²/4πR²= 1/2 So we get (r/R)² = (1/2)² It can be WRITTEN as r/R = 1/2 Consider V 1 and V2 as volumes of the respective SPHERE:- V1/V2 = 4/3πr³/4/3πR³ We can write it as (r/R)³ = (1/2)³ = 1/8 Therefore, the ratio of their volumes is 1:8.

48.

The surface area of two spheres are in the ratio 1:4 .Find the ratio of their volumes

Answer»

CONSIDER r and R as the RADII of two spheres

We know that

4πr²/4πR²= 1/2

So we get

(r/R)² = (1/2)²

It can be WRITTEN as

r/R = 1/2

Consider V 1 and V2 as volumes of the respective SPHERE:-

V1/V2 = 4/3πr³/4/3πR³

We can write it as

(r/R)³ = (1/2)³ = 1/8

Therefore, the ratio of their volumes is 1:8.
