So remember the rule from negative exponents to fractions is:
. Note that it is only the y exponent with the negative exponent, not 5, so our fraction would look like this:
.
In short, the correct answer is the third option: 5/y^3.
1. 160 2. 520 3.240 hopefully they are right
11 centimeters
This is because a rectangle has an area of length times width and so you can divide 88 by 8 to get 11
Let the thickness (or the depth) of the shown figure = t
Total surface area =
=

= 10.6875 + 12.5
= 23.1875
∴ Volume = 23.1875 t
Answer is 360.....
135/3 = 45
45 * 8 = 360
