How many lines of symmetry does the figure have? If the figure has no line symmetry, enter the number
1 answer:
Answer:
One
Step-by-step explanation:
Line of symmetry of a figure is an imaginary line about which the figure can be divided into two equal halves.
In other words, a line passing the center of the figure about which we can fold the figure into two halves overlapping each other.
For the trapezoid given in the figure, line of symmetry will be a vertical line perpendicular to the parallel sides.
Therefore, The figure has 1 line of symmetry.

Constraints are simply the subjects of an objective function.
The inequality that represents the constraint is:
Represent the number of hats with x, and the number of scarves with y.
From the question, we have:
- He spends 12 hours to knit a hat
- He spends 6 hours to knit a scarf
So, the equation of the total time spent is:
This time spent is not more than 20 hours.
So, the inequality is
Hence, the inequality that represents the constraint is:
