Answer:
All squares are parallelograms, and all rectangles are quadrilaterals are both true
Step-by-step explanation:
The formula for volume of a cylinder is:
Volume = PI x r^2 x h, where r is the radius and h is the height.
Volume = PI x 18^2 x 40
Volume = PI x 324 x 40
Volume = PI x 12,960
The exact volume would be 12,960PI cubic ft.
The decimal answer would vary depending on what value of PI is used.
First do
3x + -5x = -2x
Then do
-2x + 5x = 3x
Lastly do
3x+1
X-18 = 2 (X-25)
x-18 = 2x - 50
-18 = x - 50
32 = x
check
32-18 = 14 = 2(32-25) = 2*7
32 is the answer
672 dollars is the net price because 15 percent off of 10 percent of 662 dollars is about 10 dollars and 10 + 662 is 672
