Answer:
160.14 mm^2
Step-by-step explanation:
Area of a circle = pi r^2
subtract the area of the smaller circle from the larger
note that the smaller radius = 7 mm
pi ( 10^2 - 7^2 ) =
3.14 ( 51) = 160.14 mm^2
Answer:
In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.
then if we have the points (a, b) and (c, d)
The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.
Then the vertical change between the points (2.5 , 1) and (5, 2) is:
2 - 1 = 1 unit.
The horizontal change between the points (2.5, 1) and (5, 2) is:
5 - 2.5 = 2.5 units.
Answer:
5/12
Step-by-step explanation:
change 1 1/4 to improper fraction:
1 1/4=5/4
find common denominator: 12
5/4=15/12
5/6=10/12
subtract:
15/12-10/12=5/12
hopefully this helps :)

Answer:
Step-by-step explanation:
The union of two sets P and Q, denoted as 
is the set of all elements that are in the set P or in the set Q or in both sets P and Q.
Given:
P = {7, 8, 9, 10, 11}
Q = {1, 2, 3, 4, 5}
Then
When writing the union set, simply write all elements from both sets in on set.
