I have 98 apples I give my one of my friends 50 how much apples do I have left

What is the volume of the sphere shown below with a radius of 3?

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.

What are the solutions of the equation x4 – 5x2 – 14 = 0? use factoring to solve. someone !
