A hot air balloon is filled with 1.39 × 106 L of an ideal gas on a cool morning (11 °C). The air is heated to 105 °C. What is the volume of the air in the balloon after it is heated? Assume that none of the gas escapes from the balloon.
An ideal gas is allowed to expand from 6.00 L to 45.0 L at constant temperature. By what factor does the volume increase? ? Number The pressure will Increase by that factor or decrease by that factor? If the initial pressure was 105 atm, what is the final pressure?
In a survey of 2000 adults 50 years and older of whom 40% were retired and 60% were pre-retired, the following question was asked: Do you expect your income needs to vary from year to year in retirement? Of those who were retired, 33% answered no, and 67% answered yes. Of thos...

Find dy/dx using implicit differentiation of xy + sin^2y=10350. Is it -y/(x+2siny)
Dervative of cos(x) is -sin(x) so it would be negative.
How do you solve this equation; There are 128 7th graders at Mark's school, if there are 16 more girls than boys, how many 7th grade boys are there?
From the window of a building, a ball is tossed from a height y0 above the ground with an initial velocity of 9.40 m/s and angle of 23.0° below the horizontal. It strikes the ground 5.00 s later. By how much does the ball clear or fall short (vertically) of clearing the cr...
