Problem SolVing and Dimensional Analysis Problem: Suppose you have to pick up doughnuts on your way to school. You need 2 dozen for the class, but you stop at a store that only sells by the doughnut. How many do you get? Problem: The cost of a jar of pickles is $2.06. You have S10.00. How many jars of pickles can you pick up? Both problems involve conversions. Conversion factor- a ratio of the two parts of statement that relates the two units (= 1) Ex. 2.85 cm ? in Ex. 1.12 in =? cm

You rent a Peugeot in Sarlot France to go see  chateau Baynac. Its gas rating is 17.2 km/L. Convert this to miles per gallon using the following conversions; 1 L = 1.06 qts, 4 qts = 1 gal, 1 mile = 1.609 km. (report answer, a space, then units, miles/gallon)

2 how do you find the answer and what is the answer for each component using the volume of first table?

Use dimensional analysis to solve. Thanks.

Macmillan Learning Andre, a physics undergraduate, enters a coffee shop that is holding a contest, Customers who guess the number of coffee beans inside of a closed, 20.0 fl oz aluminum commuter mug get a free pastry and an espresso drink. Motivated by the prospect of free food and coffee, Andre puts his finely-tuned estimation skills to work. Andre assumes that a typical coffee bean is about 1 cm long, Based on that assumption, what should Andre submit as his estimate for the number of coffee beans in the mug? estimate: TOOLS coffee beans
