“Eight hundred thousand Tutsis killed in a hundred days--that’s five and a half lives terminated every minute” (Gourevitch 133). The deaths of these Rwandan Tutsis are the result of the 1994 genocide committed by the Hutus in Rwanda. Ethnic conflicts between the two groups can be traced to the early 1800s, when the Tutsi minority held most of the powerful political positions while the Hutu majority were mainly peasants. However, the two groups spoke the same language, intermarried, and followed the same religion without partitions until the Germans colonized Rwanda (Bodnarchuk 17). The Germans favored the Tutsis for their supposed “fine oval faces, large eyes, and high noses” (Gourevitch 52). Doing so forcibly separated the so called “superior race” of the Tutsis from the Hutus (52). One author who researched these ethnic distinctions were researched is Philip Gourevitch, who traveled to Rwanda to interview survivors of the genocide so he can understand why the genocide began in his history, We Wish to Inform You That Tomorrow We Will be Killed With Our Families. In his history, Gourevitch particularly explores the physical and economic differences between the Hutus and Tutsis as the driving force behind nightmare.

I don't get this math problem for my homework. Could you show me how you solve it? Please and thanks! It's under the topic of "Calculating the Radius or Diameter of a Circle." This is the problem:

Kim was playing checkers. While waiting for a turn, Kim rolled a game piece one complete turn and measured the distance. The checker rolled 4.4 cm. What is the diameter to the nearest tenth?

I don't get how to solve for that. Like in the other problems, it would say, the circumference is... or the area is...so I don't get how to do this. Please help!!!

A lot of people give wrong answers. You would be better off reading the information you need from a more reliable source.

This is similar to the other question I asked, but it involves a price as well.

Question reads:

At $1.90 each item, the supply was 410 million items and the demand was 455 million items.

When the price rises to $2.70 per item, the supply increases to 430 million and demand decreases to 415 million.

Assume the price-supply and price-demand equations are linear and find the equation that relates price and supply, another equation that relates price and demand, and then find the equilibrium point.

-end question.

Again, any help will be appreciated

P.S. I think the equation is .10(20) + .05(x) = .08(20 + x) , but for some reason, i'm not getting the answer i'm supposed to get. Am i setting up the problem wrong or solving it wrong? Thanks.

My cousin in kindergarten has to do a project that requires him to make something out of 100 of the same items (ex. a fence made out of 100 popsicle sticks). They're being asked to abstain from using food items because they will attract ants.
