Answer:
we will change the problem in stages
pre-place 1 in x1 & x4, and 4 in x2, thus guaranteeing their minimum requirements.
now 19 pencils remain to be distributed
when there are no restrictions on distributing n identical objects to k distinct piles, the formula is (n+k-1)C(k-1) which here translates to 22C3
finally, we need to see that x3 = 5, so we place 6 in x3 (guaranteeing that it violates the condition), and subtract such violations, ie (22-6)C3 = 16C3
ans: 22C3 - 16C3 = 980
Given that a particular country has an estimated 4760 nuclear weapons out of an estimated total of 15350 nuclear weapons worldwide.
To find the percentage of the nuclear weapon owned by the country we have:

Therefore the country has 31.01% of the total nuclear weapons.
ANSWER:
31.01%
10.5 X 4 = 42 X 3 = 126
50 X 4 = 200
200 +126 = 326 Feet
