Hey factory can produce fifth refrigerators in eight hours how many hours would it take to produce 1250 refrigerators
jarptica [38.1K]

Hey, I'm assuming you mean five refrigerators every eight hours. So . . .

1250 divide by 5. Which gives you 250.

Then take that 250 and multiply it by 8, and you have 2000.

So it would take 2000 hrs for a factory, that can produce 5 refrigerators every eight hours to, produce 1250 refrigerators.

What value of x would make the figure below a parallelogram? please show your work!​
lara31 [8.8K]

Answer:

x = 8

Step-by-step explanation:

Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.

16x-4 + 7x = 180, combine like terms

23x - 4 = 180, add 4 on both sides (isolate variable)

23x = 184, divide 23 on both sides

x = 8
