Answer:
find where they intersect on the graph or find each line's individual equation and set them equivalent to eachother. x=2
The expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x
<h3>How to determine the
expression represents the
number of packages of
mulch that will be needed to cover both rounded ends?</h3>
The given parameters are:
Area covered = 300 square feet
Number of ends = 2
So, the total surface area is:
Total surface area = Area covered * Number of ends
This gives
Total surface area = 300 * 2
Total surface area = 600 square feet
Let the area covered by each package of mulch be x.
So, the number of mulch is
Number = Area covered/area covered by each
This gives
Number = 600/x
Hence, the expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x

Answer:
512
Step-by-step explanation:
Suppose we ask how many subsets of {1,2,3,4,5} add up to a number ≥8. The crucial idea is that we partition the set into two parts; these two parts are called complements of each other. Obviously, the sum of the two parts must add up to 15. Exactly one of those parts is therefore ≥8. There must be at least one such part, because of the pigeonhole principle (specifically, two 7's are sufficient only to add up to 14). And if one part has sum ≥8, the other part—its complement—must have sum ≤15−8=7
.
For instance, if I divide the set into parts {1,2,4}
and {3,5}, the first part adds up to 7, and its complement adds up to 8
.
Once one makes that observation, the rest of the proof is straightforward. There are 25=32
different subsets of this set (including itself and the empty set). For each one, either its sum, or its complement's sum (but not both), must be ≥8. Since exactly half of the subsets have sum ≥8, the number of such subsets is 32/2, or 16.
