Answer:
x= 3 inch should be turned up on each side
Step-by-step explanation:
Let the height of trough be x.
Width of trough be 12 - 2x.
and length of trough = 120 inch
Volume of trough, V = L×W×H = 120 × (12-2x) × x = 120x(12 - 2x)
For maximum volume, we find V' = 0
i.e 1440 -480x = 0
or x =
or x= 3
Hence x= 3 inch should be turned up on each side
I believe about two thirds
Let the measure of side AB be x, then, the measue of side AE is given by
.
Now, ABCD is a square of size x, thus the area of square ABCD is given by
Also, AEFG is a square of size
, thus, the area of square AEFG is given by
<span>The sum of the areas of the two squares ABCD and AEFG is given by
Therefore, </span>the number of square units in the sum of the areas of the two squares <span>ABCD and AEFG is 81 square units.</span>
Answer:
1/2
Step-by-step explanation:
1/4=2/8
2/8+2/8=4/8=1/2
