In one of her experiments, she used a binary mixture of n-pentane (density 39.1 lbm/ft^3) and p-xylene (density 53.8 lbm/ft^3). One outlet stream of her condenser was measured to have a flow rate of 37 ft^3/min and a concentration of 30/70 n-pentane/p-xylene by volume. The other outlet stream was measured to have a flow rate of 22 ft^3/min and a concentration of 50/50 n-pentane/p-xylene by volume. If the system operates at steady state and the only inlet to her condenser has a flow rate of 59 ft^3/min, what is the inlet concentration of n-pentane in % by volume? Your answer should be between 0 and 100. Round your answer to 1 decimal place for entry into eCampus. Do not enter units. Example: 12.3

On the contrary, they give it into the charge of some trustworthy person among the whites, until their rightful heir takes possession of it. They are careful to observe the hours of prayer, and assiduous in attending them in congregations and in bringing up their children to them. - Ibn Battuta "Travels in Asia and Africa," 1325-1354 Using the prompt, which explains why Timbuktu became such an important urban center in the Mali kingdom?

Assume a program contains a void function named calcNewPrice (). The function receives two double variables named oldPrice and newPrice. The function multiplies the contents of the oldPrice variable by 1.1, then stores the result in the newPrice variable. Which of the following can be used to call the calcNewPrice () function? (A) calcNewPrice (double oldPrice, double newPrice); (B) calcNewPrice (&oldPrice, newPrice); (C) calcNewPrice (oldPrice, &newPrice); (D) calcNewPrice (oldPrice, newPrice);

Two variables, num_boys and num_girls, hold the number of boys and girls that have registered for an elementary school. The variable budget holds the number of dollars that have been allocated to the school for the school year. Write code that prints out the per-student budget (dollar spent per student). If a division by zero error takes place, just print out the word "unavailable".
