Answer:
Step-by-step explanation:
If we assume that initially
Number of red counter is 1
Number of blue counter is 3
Now to make ratio reverse you need to add 8 more red counters so that ratio becomes
9:3=3:1
Answer:
93.5 square units
Step-by-step explanation:
Diameter of the Circle = 12 Units
Therefore:
Radius of the Circle = 12/2 =6 Units
Since the hexagon is regular, it consists of 6 equilateral triangles of side length 6 units.
Area of the Hexagon = 6 X Area of one equilateral triangle
Area of an equilateral triangle of side length s = 
Side Length, s=6 Units

Area of the Hexagon

9x + 1 = 7x - 9
-7x. -7x
2x + 1 = -9
-1. -1
2x = -10
Divide by 2
x = -5
Answer:
26 units^2
Step-by-step explanation:
the area of a kite is (d1 * d2)/2
d1 = 2 + 2 = 4
d2 = 6 + 7 = 13
4 * 13 = 52
52 / 6 = 26
26 units^2 is your answer
Answer:
Step-by-step explanation:

In this situation a = 1, b = 2

1 + 4 = 
5 = 
c = 
This is an important mathematical theorem to know. It's called the Pythagorean Theorem.
