The area of the blue outer ring is given by the area of the entire circular archery less the area of the inner pink circle.

The area of a circle is given by

Area=\pi r^2, where r= \frac{d}{2}, r is the radius, d is the diameter.

Therefore, the area of the outer blue ring is given by:

Area=\pi\left( \frac{24}{2} \right)^2-\pi\left( \frac{6}{2} \right)^2 \\  \\ =\pi(12^2-3^2)=\pi(144-9) \\  \\ =135\pi\ in^2

german

Answer:

Read the explanation!

Step-by-step explanation:

<em>Let the "certain number" be </em>x<em>. </em>

(* is a symbol for multiplication).

<em>Create a few equations and expressions:</em>

The sum of 12 and a certain number: 12 + x

The product of 3 and the number: 3 *x = 3x

The sum of 12 and a certain number is equal to the product of 3 and the number:

12 + x = 3x

Solve!

12=3x-x

12=2x

x=6

Simplify the expression 3(x + 3) - 2x
den301095 [7]

Answer:

the answer is x + 9

Step-by-step explanation:

3 times x equals 3x and 3 times 3 equals 9 -2X

you need to add like terms together

3x+2x=5x

and then 9 is by itself

so x+ 9 is the answer

hope this helps :-)

Find the maximum production level p = 100x^{0.34}y^{0.66} if the total cost of labor (at $72 per unit) and capital (at $40 per u
Anton [14]

Maximum production p=552728

Step-by-step explanation:

The equation for maximum production is : p=100x^{0.34} y^{0.66}

The number of units of labor is x @$72

The number of units of capital is y @$40

The total cost of labor and capital is limited to $270,000, this can be written as;

72x+40y ≤ $270,000

Graphing the inequality to find values of x and y ,from the graph;

x=3750 units

y=6750  units

Applying the expression for maximum production

p=100*x^{0.34}* y^{0.66} \\\\p=100*3750^{0.34} *6750^{0.66} \\\\p=552727.56\\\\p=552728
