Answer:
The area of the composite area is 400 square millimeters.
Step-by-step explanation:
The area of the composite figure (
), in square millimeters, is found by multiplying the area of the equivalent rectangle, in which a semicircle of the original rectangle is move to the opposite side of the figure, so that quantity of area is conserved:
(1)
Where:
- Width, in millimeters.
- Height, in millimeters.
If we know that 
, the area of the composite figure is:
The area of the composite area is 400 square millimeters.
Answer:
SAS similarity theorem
Step-by-step explanation:
Both the triangles are similar by SAS similarity theorem.
Since the new slope would be calculated to -3, the equations are neither parallel or perpendicular in accordance to each other.
Answer:
Step-by-step explanation:
<em>See attachment for number line</em>
From the attachment, we have the following details:
The first shade of blue covered 10 blocks
The second shade of blue covered 5 further blocks which totaled to 15
So, the fraction of the blue blocks is:
Divide fraction by 5/5
Also from the attachment:
The shaded block stopped at the fraction:
So, the expression that represents this scenario is:
