There are 70 historical fiction books in the school library. Historical fiction books make up 1/10 of the library's collection. The equation 1/10b = 70 can be used to find out how many books the library has. solve the equation to find the total number of books in the library's collection. Use numbers and words to explain how to solve 1/10b = 70.​

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
