Divide the price by the quantity:
Bananas = 5.40 / 6 = 0.90 each
Oranges = 2.56/8 = 0.32 each
Apples = 4.68 / 12 = 0.39 each
Mangos = 3.16 / 4 = 0.79 each
Oranges have the lowest price each so are the best buy.
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
We have a=2, b=√11 and c=√15
2² + (√11)² = 4 + 11 = 15
and
(√15)² = 15
15 = 15 ⇒ right triangle.
Hope this helps.
If you have a set of points ( or numbers starting off, like (1,1) and (2,2) or what so ever. you have a slope. As long as you numbers continue to grow, remain constant, or decrease, you have Linear Data
Linear is a smart word for "Straight.
Think of it like this. Your parents give a dollar a day.
Day one you have one dollar
day two you have two dollars.
So if you can figure the slope of the line. you can figure how much you will have in a month!.
