Answer:
=760
Step-by-step explanation:
Area: 
diameter= 44
radios= 22
area of full circle:
3.14(22)^2
= 1519.76
Area of half circle"
1519.76/2= 759.88
=760
a) Rectangles always have 4 right angles (90 degrees), but parallelograms do not always have 4 right angles rather they can, but do not have to. Rectangles have to.
b) A square is a type of rectangle, but a rectangle is not a type of square. Both rectangles & squares have 4 right angles and are always quadrilaterals, but squares always have all sides that have the same length, but rectangles do not have to have their sides all equivalent lengths.
c) In the case of a parallelogram, the opposite sides are equal whereas in a rhombus all four sides are equal.
Answer:
x = 11
Step-by-step explanation:
1) A line is equal to 180°. Subtract 70° from the 180°:
180 - 70 =
110
2) To find x set 7x +33 equal to 110:
110 = 7x +33
3) Subtract 33 from both sides:
77 = 7x
4) Divide both sides by 7
x = 11
Answer:
The solution is: x = -1, and y = 8/3
Step-by-step explanation:
Notice that the system of equations can be easily solved via the "elimination" method, by subtracting term by term one equation from the other. Doing such will remove completely the term in "y" (since the terms in "y" are exactly equal in both equations), and leave only an equation containing "x", for which the value can be solved:

Now we use this x-value in either equation to solve for y:
