Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
The applicable exponent rule is ...
a^b·a^c = a^(b+c)
___
For the y factor, ...
y^-13 · y^4 = y^(-13+4) = y^-9 . . . . . exponent of -9
Step-by-step explanation:
(i) 240 ÷ 4000 = 0.06
(ii) 760 ÷ 4000 = 0.19
(iii) (20 + 10) ÷ 4000 = 0.0075
I guess this is the answer
i am not sure!!!!
Ratio of 1 to 3 means whenever there are 1 catfish, there are 1 x 3 = 3 trouts.
so if there are 200 catfishes, 200 x 3 = 600
There are 600 trouts there :D
