Ataxi cab costs $1.50 for the first mile and $0.75 for each additional mile. which equation could be solved to find how many miles you can travel in a taxi for $10 given that x is the number of additional miles? a. 1.5x - 0.75= 10 b.0.75x + 1.5= 10 c. 0.75x - 1.5=10 d. 1.5x + 0.75=10

Acar started driving from city a to city b, distance between which is 620 miles, at a rate of 60 mph. two hours later a truck left city b and started moving towards city a at a rate of 40 mph. what distance from city a is the point where the truck and the car will meet?

What is the simplified form of square root of 400 to the 100th power ?

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?
