The complete circumfernce is 2pi
The fraction of the circumfrence is: 
(3pi/5)/(2pi)=(3pi/5)/(2pi/1)=(3pi*1)/(5*2pi)=(3pi)/(10pi)=3/10

<span>The full arc of the circumference is:</span>

<span> S = 2pi * r</span>

<span> The arch is:</span>

<span> S '= (3/5) pi * r</span>

<span> Dividing we have:</span>

<span> S '/ S = ((3/5) pi * r) / (2pi * r)</span>

<span> Simplifying we have:</span>

<span> S '/ S = ((3/5)) / (2)</span>

<span> S '/ S = ((3/10))</span>

<span> Answer:</span>

<span> The fraction of the arch is:</span>

<span><span> S '/ S = ((3/10))</span></span>

The area of a rectangle is 30 square root 3750 square inches, and the length is 3 square root 250 inches what is the width of th
Ann [662]

Answer:

width=10\sqrt{15}\ in

Step-by-step explanation:

-A rectangle's area is given by:

A=lw\\\\l=length\\w=width

Given A=30\sqrt{3750} and l=3\sqrt{250}, we substitute in the formula to solve for the width as follows:

A=lw\\\\30\sqrt{3750}=3\sqrt{250}\times w\\\\w=\frac{30\sqrt{3750}}{3\sqrt{250}}\\\\w=10\frac{\sqrt{3750}}{\sqrt{250}}\\\\=10\times \sqrt{\frac{3750}{250}}\\\\=10\sqrt{15}\ in

Hence , the rectangle's width is 10\sqrt{15}\ in

olya-2409 [2.1K]

Answer:

D. 100

Step-by-step explanation:

Mean = Sum of all numbers divided by the count of all numbers

Mean = 50

Let say that the sum of all numbers = X

50 = X / 4

200 = X

X = (20+30+50) + The 4th Value

200 = 100 + 4th Value

The 4th Value = 100
