The probability of hitting the third ring is the same as finding what percentage is the area of the third ring out of the total area of the board.

The area of the third ring = The total area of the board - The area of the second circle.

Refer to the diagram below
The diameter for the whole circle = 32 in
The radius = 16 in
The area of the whole circle = π(16)² = 256π

The diameter for the second circle = 22 in
The radius = 11 in
The area of the second circle = π(11)² = 121π

The area of the third ring = 256π - 121π = 135π

Area of the third ring as a percentage of the total area = \frac{135 \pi }{256 \pi } *100 = 52.7%

Answer:

So the answer is <u><em>0.07</em></u>

Step-by-step explanation:

Area of the bullseye = 6^2 pi = 36 pi

Area of the white ring = (6 + 5)^2 pi - 6^2 pi = 85 pi

Area of outer blue ring = (6 + 5 + 5)^2 pi - (6 + 5)^2 pi = 135 pi

Total area of target = (6 + 5 + 5)^2 pi = 256 pi

If the shooter's throws are independent of one another, then

P(3rd ring AND bullseye) = P(3rd ring) * P(bullseye)

P(3rd ring) = (135 pi)/(256 pi) = 135/256

P(bullseye) = (36 pi)/(256 pi) = 9/64

P(3rd ring AND bullseye) = (135/256)*(9/64) = 1215/16384 =<u><em> 0.07</em></u>

Answer:

  2444

Step-by-step explanation:

The total cost is the integral of the marginal cost.

  \displaystyle C=\int_{144}^{625}{\dfrac{94}{\sqrt{x}}}\,dx=\left. 2\cdot 94\sqrt{x}\right|_{144}^{625}=188(25 -12)=\boxed{2444}

The total cost of producing units 144 through 625 is 2444.

Dr. David Smith lived 1/13 of his life as a child. He spent 4/39 of his life preparing for an outstanding
stich3 [128]

Answer:

40 14/25 years

Step-by-step explanation:

Well, this certainly is fun.

First, to find the fraction of the doctor's life which 13 years represents, subtract the fractions from 1 (and in this case l stands for lifetime):

13 = (1 - (\frac{1}{13} + \frac{4}{39} + \frac{1}{2}))(l)

13 = (\frac{25}{78})(l)

So, multiply this equation by the reciprocal of 25/78 to isolate one of l:

13(\frac{78}{25}) = l

l = 40\frac{14}{25} years

Answer:

perimeter =22m

area=28square meter

perimeter of rectangle=4l

22m=4l

22÷4=l

5.5=l

l=5.5m

area of rectangle =l×b

28=5.5×b

28÷5.5=b

5.09=b

b=5.09m

length =5.5m and breadth =5.09m answer !!!!
