Chisaka has less than 145kg of food remaining in her spaceship. She needs a constant amount of food each day that she spacewalks, and a constant amount of food each day that she doesn't spacewalk. Let S represents the number of days Chisaka spacewalks and N represents the number of days she doesn't spacewalk without running out of food. 2.2S+1.3N < 145 According to the inequality, how much food does Chisaka need for each day that she does and doesn't spacewalk?

A juggler tosses a ring into the air. The height of the ring in feet above the juggler’s hands can be modeled by the function f (x) = -16 x 2 + 16x, where x is the time in seconds after the ring is tossed. Find the ring’s maximum height above the juggler’s hands and the time it takes the ring to reach this height. Then find how long the ring is in the air.

Four students working in a group are trying to find a rational number between 1 2 and 7 8 . Which student has a correct answer and explanation? A) Milo divides 7 8 by 1 2 and gets a possible solution of 7 16 . B) Sara converts 1 2 to 4 8 and then determines that 5 8 falls between the two numbers. C) Julio cross multiplies and then flips the numerator and denominator to get 14 8 as his solution. Eliminate D) Mikala adds the numerators and multiplies the denominators and determines that 8 16 is a possible solution.
