3. It is Keke’s birthday, and her parents want to surprise her with a room full of balloons. Use the Fermi process to estimate the number of balloons needed to fill Keke’s living room. Assume the living room is a rectangular prism with a length of 30 feet, a width of 45 feet, and a height of 11 feet. Assume the balloons are spheres with a radius of 0.45 feet. Show your work.

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
