Initial population of rainbow smelt: 227.
Initial population of bloater fish: 1,052.
t - number of the years;
The equation is:
227 - 19.76 t = 1,052 - 92.57 t
92.57 t - 19.76 t = 1,052 - 227
72.81 t = 825
t = 825 : 72.81
t = 11.33 years = 11 1/3 years = 11 years 4 months
Answer: After 11 years and 4 months.
The side of the congruent side of the triangle should be greater than 7 feet.
Answer:
The distance the water is traveling and the time it took.
Step-by-step explanation:
The speed formula is s= d/t so I would guess that is what the question means.
(Sorry if I didn't take a lot of time to answer, it had caps so I would guess that you needed the answer fast. )
