Answer:
250 tagged 5500 total = 15 tagged x total x=330 fish were sampled.
Step-by-step explanation:
A biologist estimated that there were 5500 fish in a lake in which 250 fish had been tagged. A ranger collected a sample in which there were 15 tagged fish. Approximately how many fish were in the sample the ranger collected?
Solving for v and combining like terms:
10 + v - 17v = 4
- v - v
10 - 16v = 4
-10 -10
-16v = -6
/-16 /-16
<u><em>v = 0.375 or 3/8
</em></u>Hope this helps!
Answer:
X = 64
Step-by-step explanation:
Comparing the two triangle put the right angle into consideration.
(17 + X)/(X + 8) = (X + 8)/X
Cross multiplying
X(17 + X) = (X + 8)(X + 8)
17X + X^2 = X^2 + 8X + 8X + 64
Collecting like terms
X^2 - X^2 + 17X - 8X - 8X = 64
X = 64
