Debbie needs 5 yards of yellow fabric, 6.5 yards of blue fabric, and 8.2 yards of orange fabric to create a quilt. if the store only sells fabric by the meter, how many total meters of fabric will she purchase? (1 yard is approximately 0.9 m) (your answer should be to the hundredths and do not put units)

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?
