A manufacturing company has an old machine which produces 25 components per hour. The company has recently installed a new machi
atroni [7]

Answer: old machine 150, new machine 280

Step-by-step explanation:

given data:

Old machine = 25t

New machine = 35t

where t = hrs

we dont know the time for old machine so we assume it to be ( t ),

while that of the new machine is ( 14-t ) hours for new machine, and sum of 430 components.

therefore;

25t +490 - 35t = 430

-10t = -60

divide both sides by -10

t = 6 hours for the first machine.

6hrs * 25 components /hr

= 150 component parts For old machine.

for new machine

= 14 - t ........... eq1.

where ( t = 6 ), substitute t into the equation

= 14 - 6

= 8 hours for the second machine

= 8 * 35

= 280 components parts

On Monday, Nalim made a journey.
xenn [34]

Answer:

Step-by-step explanation:

Let's put in some numbers to make this easier to understand.

Let's say she has to travel 20 km.

On Monday, she travels at 4 kph.  This takes 5 hours.

On Tuesday she travels 25% faster, at 5 kph.  This takes 4 hours.  

To figure percent reduction we take

100 % * (old - new) / old  

100 % * (5 hr - 4 hr ) / 5 hr

100 % * 1 hr / 5 hr

100 % * 0.20

20% reduction.
