It will cost about $0.72 for three pair of shoes assuming shoe box is rectangular shape having 12 square inches of packing paper.

Step-by-step explanation:

  • Assuming a shoe box rectangle in shape and the same size is required.
  • Length of rectangle box assuming to be 4 inches.
  • Width of rectangle box assuming to be 3 inches.
  • as we know area of rectangle is Length * Breath(Width) .
  • 12 square inches is the total packing paper required for each box.
  • To cover cost of three pairs of shoes $0.02 per square inch.
  • Each box would cost about 12 square inches * 0.02 pr square inches.
  • 0.24 square inches of packing paper will be required.
  • let three pairs of shoes be x
  • Total pairs of shoes would be= (12 * 0.02)*x
  • Answer would be for 3 pairs of shoes = 0.24*3 = 0.72 square inches.

masya89 [10]
To solve this, we must set up a Systems of Equations problem 
Let's say C stands for Coach seats bought and S stands for sleeper cars bought
Here are our equations we have enough information to make. 
c + s = 93 
115c + 290s = $20,320 
Lets solve for Coach seats first 
To do that we need a value for s 
In the first equation, s = 93 - c
Lets plug that in for S in the second equation 
115c + 290(93 - c) = $20,320 
Distribute and simplify 
115c + 26,970 - 290c = $20,320 
Combine like terms 
-175c + 26,970 = $20,320 
-175c = -6650
divide 
c = \frac{-6650}{-175}
c = 38
We just found out 38 coach seats were bought. 
Plug in 38 for C in this equation ⇒ 115c + 290s = $20,320 to find S
115(38) + 290s = $20,320 
Distribute and Simplify 
4,370 + 290s = $20,320 
290s = $15,950 
Divide 
S = \frac{15950}{290}
S = 55
We just completed the problem!
38 Coach seats were bought and 
55 Sleeper car seats were bought.

"Find the area and the circumference of a circle with diameter of 8m"
expeople1 [14]

Radius = diameter/2 = 8/2 = 4m

Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2

Circumference = pi x diameter = 8pi m ( exact) or 25.12 m

Find the volume of the wedge-shaped region contained in the cylinder x2 + y2 = 49, bounded above by the plane z = x and below by
fiasKO [112]
\displaystyle\iiint_R\mathrm dV=\int_{y=-7}^{y=7}\int_{x=-\sqrt{49-y^2}}^{x=0}\int_{z=x}^{z=0}\mathrm dz\,\mathrm dx\,\mathrm dy

Converting to cylindrical coordinates, the integral is equivalent to

\displaystyle\iiint_R\mathrm dV=\int_{\theta=\pi/2}^{\theta=3\pi/2}\int_{r=0}^{r=7}\int_{z=r\cos\theta}^{z=0}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta
=\displaystyle\int_{\theta=\pi/2}^{\theta=3\pi/2}\int_{r=0}^{r=7}-r^2\cos\theta\,\mathrm dr\,\mathrm d\theta
=-\displaystyle\left(\int_{\theta=\pi/2}^{3\pi/2}\cos\theta\,\mathrm d\theta\right)\left(\int_{r=0}^{r=7}r^2\,\mathrm dr\right)
=\dfrac{2\times7^3}3=\dfrac{686}3
