The solution is 2sqrt77/77. You just fill in 2/3 for the x's. When you do that, you do that you get (2/3)/sqrt(9-[2/3]^2) which, simplified, is (2/3)/sqrt(9-[4/9]). Now use the common denominator under the radical of 9 to get (2/3)/sqrt([81-4]\9). Simplifying even further gives you (2/3)/([sqrt(77)]/3). Now do that division by multiplying 2/3 by the reciprocal of ([sqrt(77)]/3) to get 2/sqrt77. I rationalized the denominator to get that result up there.
900 divided by 3 is 300 so 300 students bring their lunch opposed to 600 students who do not.
Answer: 315,250
Step-by-step explanation:
1. Add the numbers together
245,000 + 46,000 + 132,00 + 838,000 = 1,261000
2. Divide by the # of entries (4)
1,215,046 ÷ 4 = 315250
