Answer:

Step-by-step explanation:

The question says that the fish population of an area is being tracked and a certain of 35 were collected,tagged and released.

Later another sample was collected and it revealed that 13% of those fishes caught were the ones tagged previously.

The estimated number of fishes in that area will be:

Let X= number of fishes available in that area

13 percent of fishes caught at the second sample collection were tagged

Number of fishes collected are 35

13/100×X= 35

X= 3500/13

X= 269

The number of fishes in the pond is around 269

What are benefits of having a quadratic in standard form
jasenka [17]
Standard form allows you to easily find the y-intercept and determine if the parabola is concave up or down. Also, if it is not factorable, then it is in the correct form to apply the quadratic formula to find the x-intercepts.

If hexagon JGHFKI Is congruent to hexagon SRTQUV, which pair of angles must be congruent?
Dima020 [189]

Hey there!

If these hexagons are congruent, then each angle is congruent to the one that is in the same position as it is. In this case, I and V are congruent because they are both last. K and U are congruent because they are both second to last.

While looking over the answer options, you should be able to see that Angle J and Angle S is the only answer with angles that match up, because they are both the first angle in the set.

I hope this helps!
