There is a block hanging off a string, completely immersed in ethyl alcohol. Considering that the block is constituted by $100 \text{ cm}^3$ of aluminum and $2700\text{ kg}/\text{m}^3$ is the density of the aluminum, what is the tension force on the string?

List the four major anatomic regions of the brain.

On another trip, Roy leaves from Pecos one hour before his brother and averages 55 mi/h. Travis leaves from Dallas during rush hour so he averages only 45 mi/h. This system of linear equations represents each brother's distance d from Dallas, h hours after Roy leaves Pecos. Roy: $d = 450 - 55h$, Travis: $d = 45(h - 1)$, Solve the system by finding when Travis's distance from Dallas is the same as Roy's distance. Travis's distance = Roy's distance $45(h - 1) = 450 - 55h$ Use a graphing calculator to graph the system above a. What is the intersection point of the graphs? b. The second coordinate of the intersection point represents the distance that the brothers are from Dallas. How could you confirm this using the equations?
