Answer:
18 Milk Chocolates: 24 dark chocolates
Step-by-step explanation:
The total number of chocolates are 42
So you have Milk: Dark, in the ratio 3:4
You do 3+4 which = 7
You then divide the total ratio outcome by the total number
So you do, 42/7 =6
You then do 6 and put this into the ratio
So you do, 3x6 and 4x6, which = 18 and 24
To check if your answers correct add the ratio outcomes
And If you add 18 and 24 together, you should get your beginning total of 42

Step-by-step explanation:
I have plotted the points on the coordinate system and connected roughly using a red line. Image is attached.
The arrow created, consists of a TRIANGLE and a RECTANGLE. The area of the arrow would be:
Area of Arrow = Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 * base * height
Base is 12 units
Height is 7 units, so
Area of Triangle = 0.5 * 12 * 7 = 42
Now,
Area of Rectangle = length * height
Length is 7
Height is 4
Area of Rectangle = 7 * 4 = 28
Area of Arrow = 42 + 28 = 70 square units
In mathematics, an empty set is a unique set having no elements inside it. Its size (which is based on the number of elements inside it) is also zero.
The empty set is sometimes called a null set as well.
Empty set is given the notation of o with a diagonal line through it as shown in the attached picture.
