On a school field trip, the school requires that there are 6 teachers for every 90 students. if 135 students attend the trip how many teachers are needed? write and solve a proportion showing your work.

9 teachers are needed because each group of 15 students has a teacher. if i'm correct, what is the proportion for this? ?

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.
