A square picture with a side length of 30 cm is scaled by 60% on a photocopier. The copy is then scaled by 60% again. What is the side length of the picture after it has been successively scaled by 60% 4 times?

Answer: 10.8 cm

Step-by-step explanation: we know that 1) A square picture with side length 30 cm is scaled by 60% on a photocopier Remember that 60% =60/100 = .60

so The length of the first copy of the picture is 30(.60) = 18

2) The copy is then scaled by 60% again so The length of the second copy of the picture is 18(.60)=10.8 cm

Answer:

10.8 cm

Step-by-step explanation:

we know that

1) A square picture with side length 30 cm is scaled by 60% on a photocopier

Remember that

60% =60/100 = .60

so The length of the first copy of the picture is

30(.60) = 18

2) The copy is then scaled by 60% again

so

The length of the second copy of the picture is

18(.60)=10.8 cm
