the pressure, p (in lbs/in2) that a 160-pound person's shoe experts on the ground when walking varies inversely with the area, A (in in2), of the sole of those shoes. When the shoes have a sole area of the 40 in2, the pressure is 4 lbs/in2. Find an equation that relates to these variables.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

x = 1/2

step-by-step explanation:

hope this !

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.
