1. three- fourths of an ounce of a medication are required for a 120 lb adult. at the same rate, how many ounces of medication are required for a 200 lb adult?
2. if a train travels between two cities in 3 hours at an average speed of 65 mikes per hour hour, how long would it take at an average speed of 80 miles per hour?
3. neglecting air resistance, the distance (d) that an object falls varies directly as the square of the time (l) it has been falling. if an object falls 64 feet in 2 seconds, determine the distance it will fall in 6 seconds
4. x varies inversely as y³. x is 16 when y is 15. find x when y is 2.

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

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

the answer is 1030 it's very simple math.
