J

j=agv where a is a constant of proportionality.
j=1 when g=4 and v=5
1=a*4*5
1=20a
a=1/20
a= 0.05
j=0.05gv
When g=10 and v=9,
j=0.05*10*9
j=0.5*9
j=4.5
Answer:
9
Step-by-step explanation:
Answer:
600
Step-by-step explanation:
How to do it in your head (secret):
3*2 = 6
add 2 zeros after the 6 since there are 2 zeros in total in this equation 2<u><em>0 </em></u>and 3<u><em>0</em></u> so:
30*20 = 600
