The total percent of the design which is floral fabric made in the shape of quilt square is 13.73%.

<h3>What is area of square?</h3>

Area of square is the square of its sides length. It can be given as,

A=a^2

Here, (<em>a</em>) is the length of the side of the square.

This figure represents a design that is sewn onto a quilt square. The semicircles are a solid green fabric and the square is a floral fabric.

The area of the solid green fabric is 8π square inches. There are total 8 semicircles made by the solid green fabric. Thus the area of the one semicircle is,

A=\dfrac{8\pi}{4}\\A=2\pi

The area of the semicircle is half of πr², where r is the radius of the circle. Therefore,

A=\dfrac{\pi r^2}{2}\\2\pi=\dfrac{\pi r^2}{2}\\4=r^2\\r=2

This radius of the semicircle is equal to the side of the square. Thus, the area of the side square made with floral fabric is,

A=2^2\\A=4\rm\; in^2

Thus, the percent  floral fabric in the design is,

p=\dfrac{4}{8\pi+4}\times100\\p=\dfrac{4}{8\times3.14+4}\times100\\p=13.73\%

Thus the total percent of the design which is floral fabric made in the shape of quilt square is 13.73%.

X^2 - 9x -10 =0 has a discriminant of: a. 121 b. 72 c. -359 d. 41 e. 136
Feliz [49]
In the standard form of quadratic
ax^{2} +bx+c
the discriminant is
b^{2} -4ac
In your quadratic, a = 1, b = -9 and c = -10
Now you need to plug these values into the expression for the discriminant.

If 25% of a number is 65 and 60% of the same number is 156, find 35% of that number.
Goshia [24]

Answer:

35% of that number is 91.

Step-by-step explanation:

we need to first find 25% of what number equals 65.

65×100÷25 = 260

Then, if you use the same method again, 60% of 260 would be 156.

We know "that" number is 260, and all we need to do is find 35% of it.

35% of 260 = 91

Hope this helped :)

Answer:

\purple{ \boxed{\frac{d^{2} y}{dx ^{2} }   =    \frac{132}{ {x}^{13} } }}

Step-by-step explanation:

y =  \frac{1}{ {x}^{11} }  \\ y =  {x}^{ - 11}  \\  \frac{dy}{dx}  =  \frac{d}{dx}  {x}^{ - 11}  \\ \frac{dy}{dx}  =   - 11{x}^{ - 11 - 1}  \\ \frac{dy}{dx}  =   - 11{x}^{ - 12}  \\  \\  \frac{d}{dx}  \bigg(\frac{dy}{dx}  \bigg) =  \frac{d}{dx}  ( - 11 {x}^{ - 12} ) \\  \\ \frac{d^{2} y}{dx ^{2} }   =   - 11\frac{d}{dx}  ( {x}^{ - 12} ) \\  \\ \frac{d^{2} y}{dx ^{2} }   =   - 11(  - 12{x}^{ - 13} ) \\  \\ \frac{d^{2} y}{dx ^{2} }   =   132{x}^{ - 13} \\  \\  \huge \red{ \boxed{\frac{d^{2} y}{dx ^{2} }   =    \frac{132}{ {x}^{13} } }}
