b) A 15 cm scale has one end broken. How would you use it to measure the length of a
thread 3.6 cm long? Draw a diagram to explain the same.

Answer 1

Answer:

Explanation:

In practice, measuring 9000 metres is both time-consuming and unrealistic. Generally a sample of 900 metres is weighed, and the result is multiplied by ten to obtain the denier weight. A fiber is generally considered a microfiber if it is one denier or less. A one-denier polyester fiber has a diameter of about ten micrometres

Answer 2

Answer:

7 Smaller pieces can be made  of 50 cm in length from 3.5 m Length

Step-by-step explanation:

Rohan has a piece of cloth that measures 3.5 metres

=> Cloth Length = 3.5 m

1m = 100 cm

=> 3.5 m = 3.5 * 100

=> 3.5 m = 350 cm

Cloth Length = 350 cm

Each Smaller piece measure  = 50 cm

Number of Smaller pieces can be made =  Total Cloth Length / Smaller piece length

= 350 / 50

= 7

7 Smaller pieces can be made  of 50 cm in length from 3.5 m Length
