what i the equiation for wave velocity? 1.wave velocity = wavelength / frequency. 2.wave velocity = wave lenght + frequency. 3.wave velocity = frequency / wavelength. 4. wave velocity = wave length * frequency.​

i would also go with d hope u get it right

taxation that is paid in kind, that is with goods or services rather than money

to find this first take note the house cost is $179,000 and the rate for his area is 2.3%

now turn the fraction 2.3% into a decimal, to do so move the . over to the left two times.
