5115/1024 is the answer
Plugging the 1-10 into the power you get (5/2) + (5/4)+ (5/8)+ ...... + (5/1024)
Is this a rectangle? If it is, then it is 9*8/9=8 square feet.
If it is a general parallelogram, there is not enough information to solve the problem because we don't know the height for certain.
A. 6
There will be 6 layers of cubes, since the height is 3 centimeters and the height of the cubes is 1/2
B. 24
The perimeter is the formula 2l+ 2w. With the length and width being 8 and 4, you get 16+8 which is 24 for the perimeter of the base
$97.2
120*.75 =90 (discounted price)
90*.08 = 7.2 (amount sales tax)
90 + 7.2= 97.2
Here is a table that you can use to graph y=3/2x^2
x -2, -1, 0, 1, 2
y 6, 1.5, 0, 1.5, 6
