This can be mathematically expressed to
250 + X = 1075
where X represents the parts you produce before the shift ends
Transpose 250 to the other side by subtracting each side by 250
Thus, it goes like this
X = 1075 - 250
X = 825
You produced 825 parts in the middle of the shift.
D. X=3cm
Since the triangles are similar, just set up a proportion to solve for x.
4/8=x/6. Then just cross multiply and solve from there.
