I don't have a 100% accurate answer for the argument stating species that are still remaining from which others evolved. For example, why are there still gorillas?

I am assuming that when the contenents formed after dividing, each animal evolved to adapt to its surroundings...meaning in some areas gorillas remained to stay pretty consistent and others had to change to survive in other environments. Is my answer on the right path?

I'm a student, and I want to know pressures because when I check WFAA Weather, it shows the barometric pressure in a line graph, but it's hard to see what the pressure is. When I scroll down, it shows the sea level pressure, and it's around the mark of the barometric pressure (29.0 - 31.0).

The path of a rocket fired during a fireworks display is given by the equation s(t) = 64t^2− 16t, where t is the time, in seconds, and s is the height, in feet.

What is the maximum height, in feet, the rocket will reach?

In how many seconds will the rocket hit the ground?

Okay can someone explain to me what I have to do here. You don't need to give me the answer,but just help me get started so I can finish it.

Write a 2 column proof or paragraph proof.

Given: angle TQS is congruent to angle RSQ
angle R is congruent to angle T

Prove: Triangle TQS is congruent to trinagle RSQ

Now I realize this could be hard because I can't put the picture of the triangle,but just try your best.

THank you for your time. It is greatly appreciated!

A rancher wants to fence in an area of 580 square feet in a rectangular field using fencing material costing 1.4 dollars per foot, and then divide it in half down the middle with a partition, parallel to one side, constructed from material costing 0.6 dollars per foot.
Assuming that the partition is parallel to the side which gives the width of the field, find the dimensions of the field of the cheapest design.

Apparently there are limitations to our global growth and it has to reach a certain time or level in the future. There must be scientific or economic models to better determine when that will be.

I was just eating cotton candy at a fair last night with my kids and I was wondering what would happen if you set it on fire. It is so thin and it basically melts almost instantly in the heat of your mouth. Anyone have an educated guess or knows what happens when you set cotton candy on fire?
