laikn kaise solve kiya?

 

[exploded diper]

ans is 6...
as mode has the highest frequency......

5 is wrong but 11 is correct but how you solve

 

[A.Sagheer]

A model of a car is made to a scale of 1/40.
a, the height of the actual car is 1.5m. Find the height in cm of the model.
b, The luggage capacity of the model is 5 milliliters.
Find the luggage capacity in litres, of the actual car.
Anyone able to do the part b?

We have to use similarity concept here

ratio of simple length is 1:40 s0 ration of volumes would be 1:40^3 that is 1:64000
That means that 1 milliliter in model will equal 64000 milliltres in the car.
We will multiply it by 5 since it says model has that much milliltres.Ans will be 320000 milliLITRES(not meters)
There are 1000ml in 1 l so we will divide it by 1000 and ans will be 320 litres

Use the concept of similar volumes here

The ratio is 1: 40
The capacity of the model is 5 milliliters. It will have a unit length of 1 as it is smaller

so

5 ........ ( 1 ) ^ 3
--- : ........ ( -- )
x ....... ( 40)

x is 32000

1 liter is 1000 milliliters

So in liters, it will become 32000/1000 = 320 l

no of the person first it was a gif thn it became the pic.....

Which one?

 

[Muhammad_Hamza]

Part B???

 

[FLRNAB]

Part B???

/4x9x5 => /4 x /9 x /5 => 2x3x/5 => 6x/5

6+5 = 11?

 

[Muhammad_Hamza]

/4x9x5 => /4 x /9 x /5 => 2x3x/5 => 6x/5

6+5 = 11?

100% correct

 

[Muhammad_Hamza]

/4x9x5 => /4 x /9 x /5 => 2x3x/5 => 6x/5

6+5 = 11?

Yeh kya kiya kuch samaj nae a rha....

 

[FLRNAB]

Yeh kya kiya kuch samaj nae a rha....

/ is under root. Any number which is multiplying another number in under root can be written independently:
/5x4
can be written as
/5 x/4

Round 35.78 to 36 and 1005 to 1000 and 0.3012 to 0.3

Square root of 36 is 6 and cube root of 1000 is 10

So we will get

6 * 10
--------
0.3

=200

Oh,alright.
Thanks!

 

[A.Sagheer]

Really easy. You make 35.78 into 36, 1005 into 1000 and 0.3012 into 0.3.
So Under root 36 is 6 and cube root of 1000 is 10. 6x10=60.
60/0.3 will be 200.
You're done.
