Answer:
is not equal to 
Step-by-step explanation:
When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.
For example
and 
So

wich is clearly not equal to 0.000002015
the correct scientific notation for 0.000002015 must be:
With a negative in the power of 10, referring to a small quantity.
Answer:
10.62ft
Step-by-step explanation:
The area of a semicircle is the same as 1/2 the area of a circle.
Answer:
P + B = 14130P + 150B = 1920
Step-by-step explanation:
P + B = 14130P + 150B = 1920
P = 14 - B
130(14-B) + 150 = 1920
20B = 100
B = 100/20 = 5
P = 14 - 5 = 9
Answer:
1. Supplementary and Linear pair, 2. Adjacent, 3. Adjacent, 4. Complementary and adjacent, 5, Vertical, 6. Adjacent
Step-by-step explanation:
1. is a Linear pair because the two angles form a straight line, this means they are also supplementary because the two angles must add up to 180 degrees which is a straight line.
2. Are adjacent angles, because they share a common side and do not share any interior points.
3. Are adjacent angles, because they share a common side and do not share any interior points.
4. These angles are complementary and adjacent. They both sum to 90 degrees which makes them complementary. They are also adjacent angles, because they share a common side and do not share any interior points.
5. These are vertical angles because they are opposite angles made by intersecting lines.
6. Are adjacent angles, because they share a common side and do not share any interior points.
Length of rectangle
Rectangle 1) 23m
Rectangle 2) 14yd
Width of rectangle
Rectangle 1) 36m
Rectangle 2) 3.5yd
An expressions is an equations but without the equal sign ( = ) and without the solution ( the answer)
The formula To find the area of a rectangle is
A = base * height
or
A = length * width
Rectangle’s area written in as an expression
Rectangle 1) 23 * 36
Rectangle 2) 14 * 3.5
To find the area, you multiply the numbers
23 * 36 = 828
14 * 3.5 = 49
Rectangle’s area written as a number
Rectangle 1) 828m
Rectangle 2) 49yd
