It would rotate 360 degrees because 18 seconds is twice the amount of 9 seconds, so you need to multiply 180 by 2, which is 360, or one full rotation.
Answer:
-1.5, -1/2, 2.9, 15/4, 4.6
The square root of 56 is the irrational number with approximate value 7.48331 and exact value 2√(14).
The absolute value is how far a number is from zero. The number will always be positive unless there is a negative symbol outside of the brackets. Therefore, your answer is 11.
Answers:
Length = 270 feet
Width = 45 feet
========================================================
Work Shown:
x = width
6x = length, since it is 6 times the width
P = perimeter of rectangle
P = 2*(Length + Width)
P = 2*(6x + x)
P = 2*(7x)
P = 14x
Plug in the given perimeter P = 630 and solve for x.
P = 14x
14x = P
14x = 630
x = 630/14
x = 45
The width is 45 feet.
The length must be 6x = 6*45 = 270 feet.
