Multiplying decimals is the same as multiplying whole numbers except for the placement of the decimal point in the answer. When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
Surface area= 24 ft^2
A cube has 6 faces, so the surface area of 1 face would be 24/6, which is 4 ft^2.
The formula for the area of a square is l x w, but in a square both are equal so you're essentially squaring one side.
Therefore, the area of a square ( 4 ft^2 ) can be square-rooted in order to find the length of an edge.
= 2
Therefore, the length of 1 edge of the cube is 2 ft

Answer: the width is 7 centimeters
Step-by-step explanation:
0.09 -->0.1
and
0.11--> 0.1
a trick to remember:
5 or more raise the score, less than 5 take a dive
means if the the number next to the desired place value to be rounded is greater than 5, you raise the number, if it is less than 5 you lower it
Answer:
Step-by-step explanation:
In the rectangular complex number -9√3 + 9i, which has a standard form a + bi, the a = -9√3 and the b = 9. We need this in polar form (r, θ) where
and filling in:
(notice we do not put the i in there with the 9).
so
r = 18. Now let's move on to the angle, which is a little more difficult. The angle is found in the inverse tangent ratio:
so filling that in, we have:
Since tangent is the side opposite over the side adjacent, y is positive and x is negative in the second quadrant. This is a 30 degree angle in QII, which has a reference angle of 150 degrees. This angle in radians is 
, so the polar form of that number is (18, 
)
