Later, he catches 120 eagles; 16 eagles were
tagged. Find the best estimate for the Eagle
population?​

Answer:

There are many solutions.

Here is one of them:

1 x 4 / 10 + 14 - 2 = 12.4

Hope this helps!

:)

Answer:

Step-by-step explanation:

y =  -x + 2 -------(i)

2x - y = -5  -----------(ii)

Substitute y = -x + 2 in equation (ii)

2x - (-x + 2) = -5

2x + x - 2 = - 5

3x - 2 = -5            {add 2 to both side}

3x -2 + 2 = -5 + 2

3x = -3   { divide both sides by 3}

3x/3 = -3/3

x = -1

Plug in the value of x in equation (i)

y  = - (-1) + 2

y = 1 +2

y = 3

Answer:

x=-6

Step-by-step explanation:

2/3x+5=1

Subtract 5 from both sides:

2/3x=-4

Multiply both sides by 3:

2x=-12

Divide both sides by 2:

x=-6

Hope this helps!

Answer:

-6

Step-by-step explanation:

2/3x +5 = 1

        -5    -5

2/3x = -4

2/3x/2/3 = -4/2/3

= -6

Answer:

2102.13 mm^2

Attached is a completed image of the question

Step-by-step explanation:

Given;

Radius of the circle r = KL = 27.1 mm

Angle of unshaded region = 32°

The total angle in a circle is 360°

Angle of shaded region θ = 360° - angle of unshaded region.

θ = 360° - 32° = 328°

The Area of a circle = πr^2

Area of shaded region A = (θ/360)πr^2

Substituting the given values;

A = (328/360)×π × 27.1^2

Area of shaded region A = 2102.13 mm^2

Answer:

94.7 revolutions

Step-by-step explanation:

In the question above, we are given the following values for the fan

Angular velocity = 6.2 radians per seconds

Time = 1.6 minutes.

Step 1

We would convert the time given to seconds

1 minute = 60 seconds

1.6 minutes = ?

We cross multiply

1.6 minutes × 60 seconds

= 96 seconds

Step 2

Number of revolutions made by the fan is calculated as :

Angular velocity(rad/s)

× time(seconds)

Number of revolutions = 6.2 radians per seconds × 96 seconds

=595.2 radians

Converting from radians to revolution

1 radian = 0.159155 revolutions

595.2 radians =

Cross multiply

= 595.2 radians × 0.159155 revolutions

= 94.729056 revolutions.

Approximately to the nearest tenth = 94.7 revolutions.

Therefore, the number of revolutions the fan blade makes in 1.6 minutes is 94.7 revolutions.

1.6 minutes is 1.6 x 60 = 96 seconds.

Its angular velocity is 6.2 radians per second:  6.2 radians/second x 96 seconds = 595.2 radians.

One revolution of the fan is one circumference of the fan, which is 2pi radians.

Dividing 595.2 radians by 2pi radians gives us an answer of 94.7 revolutions.

m∠B=m∠R

Step-by-step explanation:

If you make the triangles congruent, you'll see many things like:

∠A=∠P

∠B=∠R

∠C=∠S

Line AB=Line RP

Line BC=Line RS

Line CA=Line SP

Out of the options, only m∠B=m∠R is true.

Answer:

m∠b = m∠r

Step-by-step explanation:

The triangle was reflected across line m.

A reflection is a rigid transformation. A rigid transformation does not change the measurement or size of a shape, so the pre-image and the image are congruent.

The angles on the pre-image corresponds to the angles on the image. This also is for line segments.

This means (for angle measurements):

Answer:

$13.35

Step-by-step explanation:

To find the amount of discount, multiply the discount rate by the usual price of the small TV.

discount rate * regular price

The discount rate is 15% and the regular price of the small TV is $89.00

15%*$89.00

15%*89

Convert 15% to a decimal by dividing 15 by 100, or moving the decimal place two spots to the left.

15/100=0.15

15.0-->1.5-->0.15

0.15*89

Multiply

13.35

The discount amount is $13.35

So the amount of discount is $13.35

Answer:

I believe the answers are C, D, and E. Sorry if I am wrong.

Explanation:

The discriminant is

D = b^2 - 4ac

D = (-5)^2 - 4(3)(-1)

D = 25 + 12

D = 37

This means 37 is under the square root, and we know the answers are B and F due to this. Also note with these two answer choices, they are in the form [tex]\frac{-b \pm \sqrt{D}}{2a}[/tex] where...

Choices A, C, D, and E can be eliminated as the discriminant for these is D = 13.

Answer is option B that ends with 426.288 kg.

The exponential function that models the decay of this material is [tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex] and the quantity of substance remains is 426.28 grams

Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay.

Radionuclides (or radioactive materials) are a class of chemicals where the nucleus of the atom is unstable

Given,

Half life of a certain radioactive material = 37 days

Initial amount of the material = 477 grams

Quantity of substance remains N(t) = [tex]N_{0}(\frac{1}{2})^{(\frac{t}{half-life} )}[/tex]

Substitute the value in the equation N(t) =[tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex]

[tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex] is the exponential function that models the decay of this material.

Quantity of substance remains after 6 days = [tex]477(\frac{1}{2})^{(\frac{6}{37} )}[/tex] = 426.28 grams

Hence, the exponential function that models the decay of this material is [tex]477(\frac{1}{2})^{(\frac{t}{37} )}[/tex] and Quantity of substance remains is 426.28 grams
