Question

A photograph of a bacteria enlarged 5000 times
attains a length of 5 em as shown in the diagram
What is the actual length of the bacteria? If the
photograph is enlarged 20,000 times only, what
would be its enlarged length?​

Answer 1

Answer:

2cm

Step-by-step explanation:

let the actual size of bacteria be x

so bacteria is enlarged 50,000 times to 5 cm

50,000 × x = 5 cm

x = 5/50,000

x = 1/10,000

therefore actual length of bacteria is 10^-4

Now let the enlarged size of bacteria after 20,000 be y

20,000 × 1/10,000 = ycm

y = 20,000/10,000

y = 2cm
