To determine the number of trout in a lake, a conservationist catches 120 trout, tags them and throws them back
into the lake. Later, 44 trout are caught; 11 of them are tagged. How many trout would the conservationist expect
to be in the lake?

Answer:

100 people.

Step-by-step explanation:

$4,000 (total budget) - $80 (clean-up fee) = $3,920

$3,920 divided by $39 per person = 100.51

A total of 100 people could be invited for the Neely's to stay within their budget.

The greatest number is 100 people that they may invite and still stay within their budget.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given that they have budgeted $4,000 for their reception. If the reception hall charges an $80 cleanup fee plus $39 per​ person.

We have to determine the greatest number of people that they may invite and still stay within their budget.

Here total budget = $4,000

And clean-up fee = $80

Apply the subtraction operation,

⇒ 4,000 - 80

⇒ 3,920

We need 3,920 divided by $39 per person for finding the greatest number of people that they may invite.

⇒ 3,920/39

⇒ 100.51

Therefore, the greatest number is 100 people that they may invite and still stay within their budget.

Answer: 45.43%

Step-by-step explanation:

Answer:

  45.43%

Step-by-step explanation:

Any time you want to express a number as a percentage, you can multiply it by 100%.

  0.4543 × 100% = 45.43%

Answer:

A = (- 1, 0 ) and B = (4, 0  )

Step-by-step explanation:

Given

y = x² - 3x - 4

To find the x- intercepts, let y = 0, that is

x² - 3x - 4 = 0

Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)

The factors are - 4 and + 1 , since

- 4 × 1 = - 4 and - 4 + 1 = - 3, thus

(x - 4)(x + 1) = 0

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4 ⇒ point B

x + 1 = 0 ⇒ x = - 1 ⇒ point A

two exterior angles for those angles would be 140 and 85

cross multiply and solve for x. x is about 6.43

Answer:

x = 45/7 or 6.428 (6.43)

Answer:

The third one(-20+(n-1)*)

Step-by-step explanation:

It's correct because when you plug in one of the numbers in the list, it makes the equation equal. Example Below.

n=4

n=-20+(n-1)8

4=-20+(4-1)8

4=-20+3*8

4=-20+24

4=4

Answer:

8

Step-by-step explanation:

Take the length and multiply it by 2. then take your answer and multiply it by the perimeter. Then, take that answer and divide it by 2. Hope this helps :)

Hello.

To find the perimeter of a rectangle, use the formula P = 2(l + w).

Input 39 as l.

94 = 39 + 39 + w + w

Simplify

94 = 78 + 2w

Subtract the two known numbers

94 - 78 = 16

16 = 2w

So that means w = 8.

The width is 8.

Answer:

The actual area 21600 miles²

Step-by-step explanation:

Lets explain how to solve the problem

- A drawing that shows a real object with accurate sizes reduced or

enlarged by a certain amount called the scale

- Drawing scale is a ratio between the drawing length and the

actual length

- To find the actual dimensions from the drawing dimensions use the

 scale drawing

* Lets solve the problem

- A map of a rectangular park has a length of 4 inches and a width

of 6 inches

∴ The drawing dimensions are:

# length = 4 inches

# width = 6 inches

- The scale of the map is 1 inch foe every 30 miles

∴ The scale drawing is 1 : 30

- To find the actual area find the actual dimensions

∵ The scale drawing is 1 : 30

∵ The length = 4 inches and the width = 6 inches

- By using cross multiplication

∴  1        :        30

  4       :  actual length

  6       :  actual width

∴ Actual length = (4 × 30)/1 = 120

∴ Actual length = 120 miles

∴ Actual width = (6 × 30)/1 = 180

∴ Actual Width = 180 miles

∴ The actual dimensions are 120 miles and 180 miles

∵ The area of any rectangle = length × width

∴ The actual area = 120 × 180 = 21600

∴ The actual area 21600 miles²

Answer:

k = 3

Step-by-step explanation:

Assuming the values in the table are in direct proportion, then

y = kx ← is the equation relating x and y with k the constant of proportion, thus

k = [tex]\frac{y}{x}[/tex]

To find k substitute (28, 84 ) into the equation

k = [tex]\frac{84}{28}[/tex] = 3

Answer:

Use 1 cup sugar to make 2 dozen (24) cookies.

Step-by-step explanation:

Recall that 1 dozen = 12 pieces

Write and solve an equation of ratios:  # of cookies on one side and # of cups of sugar on the other side:

  18 cookies         (3/4) cup sugar

--------------------- =  ------------------------

 24 cookies                      x

Cross-multiplying results in:

18x = 18, so that x must be 1.

Use 1 cup sugar to make 2 dozen (24) cookies.
