Answer:
Not necessarily. If picture is drawn to scale, no.
Step-by-step explanation:
Line segment EF is certainly perpendicular to line segment AC, but we don't know if it bisects or not.
If the picture isn't drawn to scale, there is no way to know if EF is a perpendicular bisector to AC or not because we do not know if AD = CD.
If the picture is drawn to scale, EF is not a perpendicular bisector to AC because we can see that AD ≠ CD and therefore EF cannot be a perpendicular bisector.

Let x represent the side length of the squares.
We have been given that an open box is made from an 8 by ten-inch rectangular piece of cardboard by cutting squares from each corner and folding up the sides. We are asked to find the volume of the box.
The side of box will be
and
.
The height of the box will be
.
The volume of box will be area of base times height.

Now we will use FOIL to simplify our expression.


Now we will distribute x.


Therefore, the volume of the box would be
.
Answer:
4√2 or 5.66
Step-by-step explanation:
x² + x² = 8²
=> 2x² = 64
=> x² = 32
=> x = √32 = 4√2 or 5.66
22.8 grams of element will be remaining after 7 minutes
Further explanation:
Given

The element reduces (1-22%) in one minute.
The process will be repeated 7 times for 7 minutes
If we have to calculate the amount of element after 7 minutes
then the total reduction will be: (1-22%)^7

22.8 grams of element will be remaining after 7 minutes
