Amanda is considering changing her running 2 miles the first week and then running an additional 2 miles each substantial week.  which week of training with her new argument with Amanda run 10 miles how many weeks?

the answer is $42.96

step-by-step explanation:

parallelogram is the   answer

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
