If we want to put a three-stage rocket into orbit 100 miles above the earth’s surface, a finalvelocity of approximately is required. Suppose that each stage is built with astructural factor and an exhaust speed of .(a) Find the minimum total mass of the rocket engines as a function of .(b) Find the mass of each individual stage as a function of . (They are not equally sized!)

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

Problem situation: caren is making rice and beans. she can spend no more than $10 on ingredients. she buys one bag of rice for $4.99. beans cost $0.74 per pound. how many pounds of beans, x, can she buy? inequality that represents this situation: 10≥4.99+0.74x drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.

Will give brainliest for correct answer 8. use the distance time graph to answer these questions: a. what does the graph tell us about the velocity of the car? b. what is the average velocity of the car? (show work) c. is the velocity reflected in the graph positive or negative?d. is there any point on the graph where the car is not moving? how do we know?
