Answer: The diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.
Step-by-step explanation:
Given: The diameter of Orla's hair strand = 0.005 cm
The diameter of Eduardo's hair strand = 0.012 cm
Clearly , 
The difference between the diameters=
Thus, the diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.
Answer: x=10
Step-by-step explanation:
2x-5=25
- 5
--------------------
2x=20
x=10
The four vertices of the new quadrilateral is the midpoints of the four sides. (5,3) and (5,-1) is ((5+5)/2,(3-1)/2)=(5,1). Midpoint between (-1,3) and (5,3)=(2,3). Midpoint between (-1,3) and (-1,-1) is (-1,1). Midpoint between (-1,-1) and (5,-1) is (2,-1). So the four vertices are (5,1), (2,3), (-1,1), and (2,-1). The resulting figure is a rhombus, centered at (2,1).
Answer: No.
Step-by-step explanation: 2n is not greater than 3.5n. picture it as if it’s on a number line (i included a picture.) 3.5 is further on the line than 2.
Using a^2 + b^2 = c^2 it means that
42^2 + 56^2 = c^2
therefore c^2= 4900
so c=70mm
