Larry read a 400 page book. he read at a rate of 10 pages per day for d days. write an equation that could be used to find out how many days it took larry to read the book.

10 * D = 400

or

400 / 10 = D (40 days)

Step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
