You want to estimate how many fish there are in a pond. Suppose you cature 140 fish, tag them, and throw them back into the pond. After a couple of days, you go back to the pond and capture 420 fish, of which 28 are tagged.
Answer:
2,100
Step-by-step explanation:
Calculation to Estimate the number of fish in the pond.
Estimated Number of fish=420 fish*140 fish/28
Estimated Number of fish=58,800/28
Estimated Number of fish=2,100
Therefore the Estimated number of fish in the pond will be 2,100
The total number of fish in the pond is 2100
Let y represent the total fish in the pond.
Data obtained from the question Tagged fish in pond = 140Captured fish = 420Captured tagged fish = 28Total fish = y =?The estimated fish in pond can be obtained as follow:
Tagged in pond / Total in pond = captured tagged fish / Captured fish
140 / y = 28 / 420
Cross multiply
y × 28 = 140 × 420
y × 28 = 58800
Divide both side by 28
y = 58800 / 28
y = 2100
Thus, the estimated fish in the pond is 2100

The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 264 centimeters in 11 seconds.
Answer: 17 seconds
Step-by-step explanation:
Here's the complete question:
The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 264 centimeters in 11 seconds. What is the time in seconds the toy robot moves when the total distance is 408 centimeters?
First, we find the constant of proportionality which will be:
y = kx
where y = Distance; x = time
264 = 11k
k = 264/11
k = 24
The time in seconds the toy robot moves when the total distance is 408 centimeters will be:
y = kx
408 = 24x
x = 408/24
x = 17
Answer:
17 secs

Write an equation in whatever form you choose with the given characteristics Perpendicular to y= -1/2x - 8 and passes through: (7. -6)
Answer:
[tex]y+ 6 = 2 (x-7)[/tex]
Step-by-step explanation:
1) Lines that are perpendicular have slopes that are opposite reciprocals of each other. y = -1/2x - 8 is in y = mx + b form, in which the number in place of m represents the slope. So, the slope of y = -1/2x - 8 is -1/2. The opposite reciprocal of it would be (remember to flip the fraction and reverse the sign) 2. So, 2 is the slope we need for the answer.
2) When you know a point that the line must pass through and its slope, you can use point-slope form ([tex]y-y_1 = m (x - x_1)[/tex]) to write an equation. [tex]x_1[/tex] and [tex]y_1[/tex] represents the x and y values of the point the line intersects, and m represents the slope. So, substitute 2 for m, 7 for [tex]x_1[/tex], and -6 for [tex]y_1[/tex].
[tex]y-(-6) = 2 (x- 7)\\y + 6 = 2 (x-7)[/tex]

Write sin (4theta) in terms of sin (2theta) and cos (2theta).
Answer:
2 sin 2 theta cos 2 theta
Step-by-step explanation:
Mathematically;
sin (4theta) = sin (2theta + 2theta)
Using the sine addition rule
That would be;
sin 2 theta cos 2 theta + sin 2 theta cos 2 theta
= 2 sin 2 theta cos 2 theta

Answer:
25) A 26) B 27) y=-3/5-6 28) y=-15/18+4 29) y=5/4+12 30) y=-4x+3
Step-by-step explanation:
25) the line perpendicular would have the equation of y=-1/4x+b. In A, I plug in those to coordinated and they both have b as equal to -2 so they are both in the same line.
26) Find the slope of those two points (-1). Parallel lines means same slope but different y-intercepts and only B has a slope of -1.
27) Substitute those two points into the formula equation y=mx+b and solve for b
28) Solve for the slope and then solve for b by substituting
29) Write that equation into slope intercept form (y=5/4x-1). Parallel lines has the same slope but different y-intercepts. Use that slope of 5/4 and substitute those coordinates
30) Write the equation into slope intercept form (y=1/4x-5). Perpendicular lines have opposite reciprocal slopes. Find the opposite reciprocal of that slope and then substitute those coordinates

Answer:
12.12
Step-by-step explanation:
SO its A special right triangle which means its. 30,60,90 triangle
we know the bigger leg is 14
so we divide that by 2 since
leg 1 = Unknown (y)
leg 2= 2y=14
Since leg 1 is basically half of leg 2, we divide leg 2 by 2 and get 7
now for the hypotenuse Its just y√3 so in this case y is 7
SO when solved 7√3 you’d get 12.12 rounded
Graph y = 3/4x + 2

Please help with this math qs!!
Step-by-step explanation:
Find the radius: 6 ÷ 2 = 3m
Circumference = 2r with pi = 3cm x 3.14cm x 2 = 18.84m
Area = pi x 3cm x 3cm = 28.27m2
Calculate the circumference and area of given triangle.
Formula applied:Circumference of circle = 2πr
Area of circle = πr²
Solution:Radius,r = diameter/2 => 6/2 = 3 m
( i ) As we know that formula of circumference,
Circumference of circle = 2πr
