Which paper ??

 

[ManalMansoor]

first of all, it says the diagram is drawn to scale.
then, 100 metres is the original length, the actual length of AB.
but it never said 1 on the diagram represents 100 metres
the length of AB in the diagram represents 100 metres in actual.
so u have to measure AB with a scale and u will get 10 cm.
this means 10 cm on this diagram represents 100 metres in actual
now 100 metres = 10000 cm

10:10000
so it should be in the form "1:n"
so therefore, simplify 10:10000 and u get this:
1:1000
did u understand or not?

Yes i did, thank you so much!

5k

 

[shoaib672002]

Nah its 5k

Is answer 1/k ?

 

[Thought blocker]

Nah its 5k

how ?

 

[DeadlYxDemon]

1 litre= 1000cm^3

so 65 litres= 65000cm^3 and 0.05= 50cm^3

Take the car as a cuboid and its lengh is 440cm (1m=100cm)

Now use this formula for volumes of similar shapes : Volume 1/Volume 2 = (length1/length2)^3

65000/50= (440/x)^3

Continue solving it youll get 40.3cm

I hope its clear .

Thanks alot Fa6oom Al-Tamimi I appreciate your help

how can we work out an equation for a line on a graph?????

Need Help

Not able to solve the "d" part!

 

[DeadlYxDemon]

how can we work out an equation for a line on a graph?????

You have to first find the gredient of the line by taking two points of the line and use this formula " y^2 - y^1/x^2 - x^1"
Then for the equation of line use ""y=mx+c" in this use a value of x & y given & use the gredient (m)

Hope this helps you!
