1. a researcher tagged 40 giant turtles in 2008. In 2009, she returned and captured 50 turtles, 16 of which were tagged. In 2010 she returned again and captured 30 turtles, 8 of which were tagged. A. Use a proportion to estimate the turtle population for 2009
B. Use a proportion to estimate the turtle population for 2010
Answers
2008 - 40 giant turtles tagged
2009 - 50 turtles capture where 16 were tagged
2010 - 30 turtles capture where 8 were tagged
2009:
40/x = 16/50
40*50 = 16x
2000 = 16x
2000/16 = x
125 = x
2010:
40/x = 8/30
40*30 = 8x
1200 = 8x
1200/8 = x
150 = x

I rounded each number to the nearest whole number and added those.
29 + 79 + 42 = 150
If you add the original numbers you would get 149.5, which rounds to 150.

Answer:
1)For, m = 3/4 , (0,4) , 4y - 16 - 3x = 0 is the equation of line.
2)For, m = 4 , (-2,-5) , y - 4x - 4 = 0 is the equation of line.
3)For, m = -1/3 , (4,-1) , x + 3y -1 = 0 is the equation of line.
Step-by-step explanation:
If m is the slope and (x0,y0) is the point on any given equation, then
by POINT SLOPE FORMULA:
The line equation is given as (y - y0) = m (x -x0)
Now , here:
1) m = 3/4 , (x0, y0) = (0.4)
So,, the equation of line is
on simplification, 4y - 16 - 3x = 0 is the equation of line.
2) m = 4 , (x0, y0) = (-2.-5)
So,, the equation of line is
on simplification, y - 4x - 4 = 0 is the equation of line.
3) m = -1/3 , (x0, y0) = (4, -1)
So,, the equation of line is
on simplification, x + 3y -1 = 0 is the equation of line.

How do you get the y alone?
Answers
The answer is y = x-4.
Step-by-step explanation:
- The given expression is x-y=4
- Keep y alone on one side and move remaining terms to the other side.
⇒ -y = 4-x
- To have y alone, Multiply the above expression with -ve sign on both sides.
⇒ y = x-4

When the basketball player made 40% of the shots she attempted. She made 32 baskets she attempts80 shots.
What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that,
Basketball players made 40% of shot
Number of baskets made = 32
Arithmetic operation is the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
Let the number of shots attempted to be x.
As a result,
40% of x = 32
(40/100) × x = 32
x = 80
Thus, when the basketball player made 40% of the shots she attempted. She made 32 baskets she attempts80 shots.

This means 16 baskets is 20%. Now that 20% goes nicely into 100% you multiply 16 by 5 and 20 by 5 to get 80.
The basketball player made 80 shot attempts.
