Answer:
D 85/95
Step-by-step explanation:
17/19
Multiply the top and bottom by 3
17/19 *3/3 =51/57
Multiply the top and bottom by5
17/19 *5/5 =85/95
Regular shapes are shapes that have sides that are all equal and interior angles are also equal.
Irregular shapes are shapes that vary in the measurement of sides and interior angles.
To find the area of an irregular shape, break it down into various regular shape and individually compute its area. Add up all the area of the regular shapes formed from the irregular shape to get the area of the irregular shape.
An example of an irregular shape is the outline of a house.
Pointed roof over a square room. There are two regular shapes found in this irregular shape. A square and a triangle. Compute its individual area and add up these two areas to get the area of the house.
Answer:
Let us say the domain in the first case, has the numbers. And the co-domain has the students, .
Now for a relation to be a function, the input should have exactly one output, which is true in this case because each number is associated (picked up by) with only one student.
The second condition is that no element in the domain should be left without an output. This is taken care by the equal number of students and the cards. 25 cards and 25 students. And they pick exactly one card. So all the cards get picked.
Note that this function is one-one and onto in the sense that each input has different outputs and no element in the co domain is left without an image in the domain. Since this is an one-one onto function inverse should exist. If the inverse exists, then the domain and co domain can be interchanged. i.e., Students become the domain and the cards co-domain, exactly like Mario claimed. So, both are correct!
