A hybrid car achieves an average of 54 miles/gallon on the highway and 41 miles/gallon in the city. Estimate the average miles/gallon for a trip consisting of 204.5 miles on the highway and 32.8 miles in the city, then convert this number to SI units (km/L). (Consider 1 gallon = 3.8 L and 1 mile = 1.41 km.)

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
