The top one is called a open dot, they are similar because they are facing the same direction, they are different because the top is a open dot and the bottom is a closed dot
The percentage increase of a given quantity from 20 to 40 is 100%.
Original quantity = 20
New quantity = 40
In order to calculate the percentage increase, one had to subtract the original quantity from the new quantity and then divide the value by the original quantity. This will be:
= (New quantity - Original quantity) / Original quantity × 100
= (40 - 20) / 20 × 100
= 20/20 × 100
= 1 × 100
= 100%
Therefore, the percentage increase of the quantity from 20 to 40 is 100%.

Hello!
All lines within a circle are the same length
We first have to find the length of one of the lines.
7 + 4 = 11
Now we find what we are missing from the second line
5 + z = 11
z = 6
The answer is C)6
Hope this helps!
Answer:
x = -8/2
Step-by-step explanation:
To make the equation easier to work with, our first step will be to make all of our fractions have a common denominator. Both 2 and 4 are factors of 8, so that will be our common denominator.
Old Equation: 1/4x - 1/8 = 7/8 + 1/2x
New Equation (with common denominators): 2/8x - 1/8 = 7/8 + 4/8x
Now, we're going to begin to isolate the x variable. First, we're going to subtract 2/8x from both sides, eliminating the first variable term on one side completely.
2/8x - 1/8 = 7/8 + 4/8x
-2/8x -2/8x
__________________
-1/8 = 7/8 + 2/8x
We're one step closer to our x variable being isolated. Next, we're going to move the constants to the left side of the equation. To do this, we must subtract by 7/8 on both sides.
-1/8 = 7/8 + 2/8x
- 7/8 -7/8
______________
-1 = 2/8x
Our last step is to multiply 2/8x by its reciprocal in order to get the x coefficient to be 1. This means multiply both sides by 8/2.
(8/2) -1 = 2/8x (8/2)
The 2/8 and 8/2 cancel out, and you're left with:
-8/2 = x
I hope this helps!
