Answer: There are 104 silvery minnow population in the Rio Grande River.
Step-by-step explanation:
Since we have given that
Number of tagged silvery minnows = 54
Number of captured silvery minnows = 62
It includes 12 tagged silvery minnows.
So, Number of silvery minnows without tags = 62 -12 =50
So, Good estimate of the silvery minnow population in the Rio Grande River would be
Hence, there are 104 silvery minnow population in the Rio Grande River.
Answer:62 feet
Step-by-step explanation:
1 yard=3 feet
20 yard=20 x 3=60 feet
20 yards=60 feets
20 yards and 2 feets=60 feet + 2 feet
20 yards and 2 feets=62 feet
Given:
Two end points of a line segment are (7,2) and (10,-5).
To find:
The gradient of the given line segment.
Solution:
We know that, gradient of a line segment is the slope of that line segment.
The end points of the line segment are (7,2) and (10,-5), so slope or gradient of the line segment is
Therefore, the gradient of the given line segment is .
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 54 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 54 is 100%, so we can write it down as 54=100%.
4. We know, that x is 2.9% of the output value, so we can write it down as x=2.9%.
5. Now we have two simple equations:
1) 54=100%
2) x=2.9%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
54/x=100%/2.9%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 2.9% of 54
54/x=100/2.9
(54/x)*x=(100/2.9)*x - we multiply both sides of the equation by x
54=34.48275862069*x - we divide both sides of the equation by (34.48275862069) to get x
54/34.48275862069=x
1.566=x
x=1.566
now we have:
2.9% of 54=1.566
