A test consists of two parts. Part 1 contains 4 questions to be answered true or false. Part 2 contains 8 multiple-choice questions each with 5 possible responses. How many ways are there to fill out an answer sheet if a student must complete both parts 1 and 2?

If your asking how much altogether for 12 performance the answer will be 98,496.

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
