Calculate the amount of water used for a shower
1. government laws require that now showerhead flow rates be no more than 2.5 gallons per minute. if you take one 10 minute shower a
day, the following measurement equalities apply:
25 gallons = 1 minute
10 minutes = 1 shower
1 shower = 1 day

How can constraints be used to model a real-world situation?

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?
