Which expression can be used to determine the reference angle for an angle, x, measuring 150°? 180 degrees minus x x minus 180 degrees 360 degrees minus x x minus 360 degrees

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
