She knows that the gravel bases need to fit entirely inside the pen, so the sum of the diameters of the gravel bases
cannot exceed the width, y.
sarah has at most $150 to spend on materials. the cost will be $4.00 per linear foot of fencing and $2.00 per square foot
of the gravel bases (the cost of the gravel at 1 inch of depth).
(recall: the area of a circle is a = *r? , where r is the radius.)
part a
write the system of inequalities that can be used to determine the length and width of the pen and the radii of the gravel
bases for the food containers. use the diagram of the pen and containers above to . base your inequality statements
on the dimensions and their limits and the cost limits for the project.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

1. sometimes

2. never true

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
