Each week for the last 9 weeks, Sandra deposited $5 into her piggy bank, which already had $15 in it. Now she has saved enough money to buy tickets for all 5 of the members of her family to go see a movie. Which expression and value show the cost of each movie ticket? [9 × 5 + 15] ÷ 5; $9 [9 × 5 + 15] ÷ 5; $12 9 × 5 + 15 ÷ 5; $9 9 × 5 + 15 ÷ 5; $12

Equation for the calculation double 2 and then add 5

What are two numbers that add up to -9 and multiply to -10 best answer gets branliest and 100 extra points

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?
