Answer:
17
Step-by-step explanation:
c=15×15+8×8
c=225+64
c=289=17
Answer:
That's easily true
Step-by-step explanation:
To compare these numbers, you must first put them into one format. Since you have mixed numbers, you may have to find and use the LCD.
-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:
-2.5, 1/5, 10, -3, (3 3/5) This set of numbers is simple enough so that you could rearrange them in ascending order mentally:
-3, -2.5, 1/5, (3 3/5), 10
In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element: 1/5.
The median is 1/5.
You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.
