Number of left tortes are, 43/16
We have to given that,
A chef prepared five chocolate tortes for a dinner party.
And, The guests consumed 2 5/16 tortes.
Now, Number of left tortes are,
⇒ 5 - 2 5/16
⇒ 5 - 37/16
⇒ (80 - 37) / 16
⇒ 43/16
Therefore, Number of left tortes are, 43/16

Answer:
The area of a triangle can be found using:
a=1/2 bh
or
a=(bh)/2
where b is the base and h is the height
Answer:
Perimeter of a triangle = a + b + c. Area\; of \; a\; triangle= \frac{1}{2}bh. Where, b is the base of the triangle. h is the height of the triangle.
Hope this helps you:)
We can construct congruent segments, segment bisectors, equal angles and angle bisectors using tools like a straightedge and compass. Using arc intersections and connecting them with straight lines help us in achieving most of these. The important thing is to understand the right points from where to make the arcs originating.
To construct congruent segments, simply measure the length of the initial segment with your compass, then use the compass to draw another segment of the same length.
To create a segment bisector, use a compass to draw two arcs with the same radius from the segment's endpoints and then connect their intersection points with a straight line. This will create a line that bisects, or divides, the original segment into two congruent parts.
For equalling angles, first construct the initial angle using a straightedge and compass. Then place the point of the compass at the vertex of the angle, draw an arc through the sides, and repeat this process to copy the angle.
To create an angle bisector, draw an arc centered at the vertex of the angle. Then, from the points of intersection of the arc with the angle, draw two additional arcs within the angle that intersect with each other. Draw a straight line from the vertex to the point of intersection of these arcs.
