tom buys only cookies and chocolate, and spends all of his income on the two items. at his current consumer equilibrium, tom buys 10 cookies and 8 chocolate bars. suppose the price of cookies suddenly falls. tom adjusts to his new consumer equilibrium, where he now buys 14 cookies and 6 chocolate bars. according to marginal utility theory,

Find the measure of the interior angles of the following regular polygons: a triangle, a quadrilateral, a pentagon, an octagon, a decagon, a 30-gon, a 50-gon, and a 100-gon.

Me. i can't figure out this question. give an explanation too. .

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
