Joe is a scientist who works with the Department of Agriculture. In order to ensure a good harvest, Joe keeps track of various local beetle populations. He catches 590 beetles, marks them, and releases them. Then later, he catches 2,000 beetles, 59 of which are marked. To the nearest whole number, what is the best estimate for the beetle population?
( 11 points if solved)
Will give brainliest, if the answer is correct OR well explaining explanation ( Either Both)

Answers

Answer 1

Answer:

There are 20,000 Beatles in the total population

Step-by-step explanation:

59 Beatles out of the 2,000 are marked (2.95% or 59/2000)

-----------------------------------------

1 / 0.0295 = 33.8983051

That means that the total population is 33.89 times larger than the 590 marked beatles.

33.8983051 x 590 = 20,0000 Beatles total

Answer 2

Answer:

Approximately 20,000 beetles

Step-by-step explanation:

The answer is approximately 20,000 beetles because Joe found 590 beetles and marked them. When he found the other 2,000 beetles, 59 of them were marked. 59 is 10% of 590. Since Joe found 2,000 beetles that must be 10% of some number. To find that number, you must multiply 2,000 by 10. So 2,000 x 10 is 20,000, so there is approximately 20,000 beetles

Write the equation in function form:
8x + 4y = 20

Answers

Write 8x+4y=20 in function form


Writing a an equation in function form is simply expressing y values in terms of x. In other words when you substitute a particular value for x, you get a particular value for y.

so

8x + 4y = 20

4y = 20 - 8x

y = (20-8x)/4 or y = (20-8x)/4 or y = f(x) = 2(10-4x)/4 = (10-4x)/2 = 5 - 2x = -2x+5

check your answer with a sample values say with a point that solves the equation or a point on the line.....see below....

(2,1)

8(2) + 4(1) = 20......16 + 4 = 20...check.......y=-2(2) + 5 = -4 +5 =1....x=2, y=1...checks....so f(x)=-2x+5

another quick check are the intercepts.....y (x=0)....or x (y=0)

8 (0) + 4 (5) = 20.....(0,5).......y=f(x) = -2 (0) + 5...x = 0..y=5 so again the function checks so

8x + 4y = 20.....is also written as the function y= f(x)= -2x + 5

Beth works at the mall for $12.75 per hour. She works for 4 1/2 hours per day on 2 days each week. How much does she make in 2 weeks? (Before taxes)

she goes to work 2 days a week so in 2 weeks she goes to work 4 days, she works 4 1/2 hours so 4 days of work equal 18 hours and 18 multiplied by 12.75 is 229.5

Answer:If I am not mistaken it should be $229.5

Which phrase describes the algebraic expression Three-fourths x + 2?
three-fourths of a number plus two
the quotient of four-thirds and two
the product of three-fourths and two
the difference between three-fourths of a number and two

Answers

Answer:

A) three-fourths of a number plus two

Step-by-step explanation:

To find out what the answer is, we first need to translate the sentence into numbers, which will give us:

[tex]\frac{3}{4}[/tex]x+2

We can see that we are multiplying an unknown number, x, by three fourths, so we know that we are taking three-fourths of a number, and we also know that we are then adding two. We are not dividing or subtracting, so we know it can't be  B or D. We also know that we are multiplying three-fourths by x, not two so we know that it can't be C. So our only option is A, So the correct answer is:

A) three-fourths of a number plus two

Hope this helps, please mark as brianliest

Answer:

Three-fourths of a number plus two

Step-by-step explanation:

The value "x" is  used in algebra to mean a value that is not yet known.

Remember the algebraic expression is: 3/4x + 2

Lets break each possible answer down,

1. The quotient of four-thirds and two is:  4/3 ÷ 2

2. The product of three-fourths and two is:  3/4 * 2

3. The difference between three-fourths of a number and two is:

3/4x - 2

None of these expressions match 3/4x + 2, which brings us to the last answer.

4. Three-fourths of a number plus two is:  3/4x + 2

Notice, "x" is represented as "of a number", since the value is unknown.

Therefore, your answer is A, three-fourths of a number plus two.

300, 80, 3 ( partial quotients)

383 (final quotient)

Step-by-step explanation:

7291 is the dividend

19 is the divisor

we have no quotient, so let us make Q our partial quotients

In step 1: Q = 5700 / 19 = 300

In step 2: Q = 1520 / 19 = 80

In step 3: Q = 57 / 19 = 3

14 Is the final remainder in which it isn't a multiple of 9

therefore the final quotient is adding all the partial quotients quotients in step 1, 2 and 3

300 + 80 + 3 = 383
