Sara owns an exotic pet store. she wants to make sure she has more than a pound of food for every 15 lizards she has in the store. if she currently has 4.25 pounds of food, how many lizards can she have in the store? which inequality can be used to solve the problem? x/15 is less than 4.25 x/15 is greater than 4.25 15x is greater than 4.25 4.25x is less than 15

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
