The degree of a polynomial in x is the greatest exponent of x when the polynomial is written as a sum of terms such as $$a_i$$$$x^i$$, where i is a positive integer and $$a_i$$, is a number. For example, the degree of $$9x^3 + 3x^5 – 100x$$ is 5. What is the degree of the polynomial$$(x+4x^3)^2$$$$(x^5-7）$$？
Near the equator, a boat traveled 17 kilometers along a straight route from point $$A$$ to point $$B$$, which is 15 kilometers north and a certain distance east of point $$A$$. The boat then traveled 12 kilometers due east from point $$B$$ to point $$C$$. The boat then traveled along a straight route from point $$C$$ back to point $$A$$. What was the total distance, in kilometers, that the boat traveled from $$A$$ to $$B$$ to $$C$$ and then back to $$A$$ ?
How many positive integers are factors of 2,200?
For how many different integer values of $$x$$ is $$\frac{4}{(x+1)}$$ an integer?
In a large gym class, the teacher plans to group the students into teams for either volleyball or baseball. The volleyball teams would consist of 6 players each, while the baseball teams would consist of 9 players each. If the teacher attempts to group the students into volleyball teams, then there will be 2 students remaining who are not on a team. If the teacher instead attempts to group the students into baseball teams, which of the following could be the number of students remaining who are not on a team?
A rectangular plastic box with inside dimensions 6 inches by 5 inches by 4 inches is 85 percent full of water and contains nothing else.Several spherical lead balls with radius 1 inch will be placed in the water until the box is at least 90 percent full but less than 95 percent full. How many of these lead balls will be placed in the water? (Note: The volume of a sphere of radius r is $$\frac{4πr^3}{3}$$.)
