Answer: Choice A) about 69.53 m^2

==========================================================

Work Shown:

A = area of the square

A = side*side

A = 18*18

A = 324 square meters

---------

B = area of the circle

B = pi*r^2

B = pi*9^2 ..... note that the radius is half the diameter

B = 81pi

B = 254.469004940773

B = 254.4690 square meters

I used the calculator's stored version of pi to compute that approximate value.

---------

C = area of shaded region

C = A - B

C = 324 - 254.4690

C = 69.531

C = 69.53 square meters

So that points us to choice A as the final answer.

---------

Side note: The shaded region is about C/A = (69.531)/(324) = 0.2146 = 21.46% of the square's area. So this is the approximate chances of landing in the shaded area if you randomly threw a dart.

Find m∠DEC (the picture is not drawn to scale).
pochemuha

Answer:

M∠DEC equals 123º.

Step-by-step explanation:

The sum of a triangle's three angles always equal 180º. The exterior angle, x, equals the two non-adjacent interior angles.

180 - {(x - 45)+(x - 12)} = m∠DEC

m∠DEC + x = 180

<u>(x - 45) + (x - 12) = x</u>

Solving for x:

(x - 45) + (x - 12) = x

x - 45 + x - 12 = x                             Remove parenthesis

2x - 57 = x                                       Combine like terms

2x = x + 57                                      Add 57 to both sides

<u>x = 57</u><u>                                             Subtract x from both sides</u>

Finding m∠D:

x - 45 = ?

<u>57 - 45 = </u><u>12º                                          </u>

Finding m∠C:

x - 12 = ?

<u>57 - 12 = </u><u>45º                                           </u>

<em>** </em><em>(Checking x: 12 + 45 = 57) </em><em>**</em>

<em>Finding </em>m∠DEC:

AC is a straight line, and because straight lines are equivalent to 180º, we subtract 57 from 180:

180 - 57 = 123º

Hope this helps,

Please help me with this problem! I am so confused: This system of equations shows x by itself on the left side of one equation.
andrew-mc [135]

Answer:

x=-6

y=4

Step-by-step explanation:

x=-y-2        x=-y-2             x=-y-2         x=-y-2         x=-y-2   x=-4-2   x=-6

0.5x+y = 1  0.5(-y-2)+y=1  -0.5y-1+y=1  -y-2+2y=2  y=4       y=4       y=4

I need help now it's an emergency please help me with this
marshall27 [118]

Answer:

Population of the 48th generation will be 4469.

Step-by-step explanation:

Recursive formula by which the population is increasing,

L_{n+1}=L_n+95

L₀ = 4

Common difference 'd' = 95

Recursive formula represents a linear growth in the population.

Therefore, explicit formula for the given sequence will be,

L_n = L₀ + (n - 1)d [Explicit formula of an Arithmetic sequence]

Here n = Number of terms

L₄₈ = L₀ + (48 - 1)(95)

     = 4 + 4465

     = 4469

Therefore, population of the 48th generation will be 4469.
