If the ratio of side lengths of similar polygons is 6:11, what is the ratio of perimeters?

1 answer:

4 0

6:11 because polygons have 4 side so it would be 24:44 but it just reduces back to 6:11. hope this helped have a good day!!

AB = 10 in; AD = 6 in A= 30sqrt3 in2 30 in2 60 in2

Ratling [72]

Answer: 30

Step-by-step explanation:

If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula $A=\frac{1}{2} ab \sin C$ .

However, since there are two triangles, we can double this, giving us $A=ab \sin C$ .

So, the area is $A=(10)(6)(\sin 30^{\circ})=\boxed{30}$

Nina [5.8K]

The maximum units is 200 and , Total revenue is $8,000

Step-by-step explanation:

Here we have , A manufacturer finds that the revenue generated by selling of cortan commodity is given by function R(x)=80x-0.2x^ 2 , where he maximum reveremany should be manufactured to obtain this maximum units .Let's find out:

We have following function as $R(x)=80x-0.2x^ 2$ . Let's differentiate this and equate it to zero to find value of x for which the function is maximum!

⇒ $R(x)=80x-0.2x^ 2$

⇒ $\frac{d(R(x))}{dx}=\frac{d(80x-0.2x^ 2)}{dx}$

⇒ $\frac{d(R(x))}{dx}=\frac{d(80x)}{dx}-\frac{d(0.2x^ 2)}{dx}}$

⇒ $0=80-2x(0.2)$

⇒ $\frac{80}{0.4}=x$

⇒ $x=200$

Now , Value of function at x=200 is :

⇒ $R(200)=80(200)-0.2(200)^ 2$

⇒ $R(200)=16000-8000$

⇒ $R(200)=8000$

Therefore , The maximum units is 200 and , Total revenue is $8,000

Blopie help me :(((((

Step-by-step explanation:

first you have to see the triangle BCD

then hypotheses and perpendicular are given so you have to find base

after finding base. In rectangle ABCD DC is length and BC is breadth so now you can find area by using the formula A = l×b

What is the area, in square inches, of the isosceles trapezoid below?

Komok [63]

A = 73.84

Explanation-

14.2 - 6.4 = 7.8 (to get the length of the base without the top part)

7.8 • 5.2 = 40.56 (to find the area outside of our subtracted square that has the top part)

6.4 • 5.2 = 33.28 (to find the area of the inner square)

40.56 + 33.28 = 73.84 (adding together both parts to find the total area)

A = 73.84
