How does music affect a musical?
Determine the frequency of a microwave 6.0 cm in length.( A microwave is an electromagnetic wave.It travels through space at a speed of 3.0 x 10 ^8 m/s)
if a wave is traveling at 60cm/second and has a wavelength of 15cm what is the frequency? Please explaine
thanks a lot bobpursely & jai :)
so you take away got it!
so, e)38e+18 f)16f+15 right?
are the rest correct
I get confused when the plus and minus clash
remove the brackets and simplify questions a) 3(2a+5)+2(a+7) b) 5(b+4)+10b c) 4(2c+3)+3(c-3) d) 8+6(d-2) e) 6(5e+3)-4(2e+3) f) 5(3f+2)-(f-5) MY ANSWERS a)6a+15+2a+14 8a+29 b)5b+20+10b 15b+20 c)8c+12+3c-9 11c-3 d)8+6d-12 I need to simplify more...how? e)30e+18-8e I need to simp...
no worries...dad explained :) thanks a lot
