Answer:
1/5^3

Step-by-step explanation:
I'm not sure how to explain this, but if there is a negative exponent, then it can be written like this, as the denominator of a fraction.
Answer:
6. it is a square because all of the outer sides are equal
3. perpendicular because the slopes are reciprocals of eachother and the lines would form 90 degree angles
Answer:
Take a fixed gap and draw 180 degree arc of equal size on each side.
The compass size should be the same for the whole process, be careful.
Make 90 degrees angle for both side and cross two arcs from each 90 degrees. The point thus obtained should be produced vertically towards the line AB. The point on the line segment is the line bisector.
SOLUTION:
If it takes 5 sewing machines 5 minutes to make 5 shirts, then that means:
100 machines will make 100 shirts in 5 minutes as well.
Hope this helps! :)
Have a lovely day! <3
