Question

A photograph of a bacteria enlarged 50,000 times,
attains a length of 5 cm. What is the actual lenth
of the bacteria? If the photograph is enlarged
20,000 times only, what would be its enlarged
length?​

Answer 1

Answer:

The lenght increases with an increment in the number of time the paragtaph enlarged.

• It is a case of direct proportion
• 1 ÷50000=x÷5 or x=5÷50000

=1 by 10000 cm = 10 to -4 power cm

Again

Number of time photograph enlarged is 50,000 and 20,000

Lenght (in cm)

We have 5 ÷50000= x by 20000

or 5×20000÷50000

we get 2

2 is the answer
