- 1-12 The life expectancy of a citizen in the United States is 76 years. Eighty years ago it was 56 years. In your opinion, what was the major contributor to this spectacular increase in life expectancy? Explain your answer.arrow_forwardThe officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 81 students, requires 8 chaperones, and costs $1,300 to rent. Each van can transport 9 students, requires 1 chaperone, and costs $90 to rent. Since there are 972 students in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 972 students. Since only 104 parents have volunteered to serve as chaperones, the officers must plan to use at most 104 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation costs? The officers should rent buses and vans to minimize the transportation costs.arrow_forwardChemistry lab students are measuring the amount of oxygen produced by a reaction. The students record the volume of oxygen produced every 15 seconds. In this experiment, which variable is the independent variable and which is the dependent variable? Both variables are dependent variables. Time is the independent variable and volume is the dependent variable. Both variables are independent variables. Volume is the independent variable and time is the dependent variable.arrow_forward
- A student notices that her father (who is trying to lose weight) is drinking a lot of diet Pepsi with the artificial sweetener aspartame. The student has read that aspartame, at high doses, may be a carcinogen. She has read that the FDA recommends no more than 50.0 mg of aspartame per kg of body weight per day. Given that her father weighs 175 pounds, how many cans of diet Pepsi can he “safely” consume per day?

- Suppose you accidentally drop a glass bowl full of sugar onto the floor, causing the bowl to shatter into pieces. Which of the procedures would be the most effective way to separate the sugar from the tiny pieces of glass? Collect all of the sugar and glass pieces into a pot and heat the mixture to melt the sugar. Then, pour the liquid sugar through a filter to separate the glass from the sugar. Collect all of the sugar and glass pieces into a bucket of water. Allow the water to dissolve the sugar, then remove the water and sugar solution, leaving the glass behind in the bucket. The solution is then heated to evaporate the water, leaving the sugar behind. Use a magnifying glass and tweezers to safely remove the glass particles from the mixture. Sweep a magnet across the spill to attract the glass particles and remove them from the mixture.arrow_forwardJollibee Burger Item Sodium(mg) Fat(g) Calories Item cost($) Beef Patty 50 17 220 $0.25 Bun 330 9 260 $0.15 Cheese 310 6 70 $0.10 Onions 1 2 10 $0.09 Pickles 260 0 ,. 5 $0.03 Lettuce 3 0 4 $0.04 Ketchup 160 0 20…arrow_forwardWhich of the following is a suspension? salt water Soda pop (e.g. Sprite, Coke, or Pepsi) Gasoline Muddy waterarrow_forward
