Factory a can produce 45 machines in 20 minutes. factory b can produce 30 machines in 15 minutes. if both factories produce machines in 2 hours, which factory will produce more machines? how many more machines will be produced?

Factory A will produce more machines

Factory A produces 30 machines more than factory B

Solution:

Given that,

Factory A can produce 45 machines in 20 minutes

Thus number of machine produced in 1 minute is:

Factory B can produce 30 machines in 15 minutes

Thus number of machine produced in 1 minute is:

Both factories produce machines in 2 hours

Find the number of machines produced factory A in 2 hours

1 hour = 60 minutes

2 hour = 120 minutes

Number of machine in 120 minute = 2.25 x 120 = 270

Thus factory A produces 270 machines in 2 hours

Find the number of machines produced factory B in 2 hours

Number of machine in 120 minute = 2 x 120 = 240

Thus factory B produces 240 machines in 2 hours

Thus,

factory A = 270 machines in 2 hours

factory B = 240 machines in 2 hours

Thus, Factory A will produce more machines

270 - 240 = 30

Thus factory A produces 30 machines more than factory B

i dont know

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
