PLEASE HELP 1) Les has 200 cubic yards of topsoil that contains 10% rocks. A customer will buy all of less has topsoil if it contains no more than 6% rocks. So Les well as some top soil that is 4% rocks so that the mixture is 6% rocks. Les must figure out how much to add.

Part A) Write the equation that models this mixture scenario

Part B) Solve the equation from part A

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

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
