Answer:
B. 18 cm.
Step-by-step explanation:
Because they are similar, we can say that segment AC corresponds to segment DF, and segment AB corresponds to segment ED. So, we can set up a proportion.


2 * x = 12 * 3
2x = 36
x = 18
So, the length of ED is B. 18 cm.

Answer:
30 parts
Step-by-step explanation:
We are given that machine produces 100 parts twice as fast as machine B does.
Machine produces 100 parts in 40 minutes.
We have to find number of parts produces by machine A in 6 minutes.
According to question
Machine A takes time to produce 100 parts =
Machine A and machine B produces parts at constant rate.
Machine A produces parts at the rate=
In one minute,Machine A produces =5 parts
In 6 minutes , machine B produces =
parts
Hence, machine A produce parts in 6 minutes=30
