Step-by-step explanation:

p = 2r + pi×r

p = r(2 + pi)

r = p/(2 + pi)

Answer:

r = $\frac{p}{2+\pi }$

Step-by-step explanation:

p = 2r + πr ← factor out r from each term

p = r(2 + π) ← divide both sides by (2 + π )

$\frac{p}{2+\pi }$ = r

Why do whole numbers with an exponent get bigger while fractions with an exponent get smaller.

ohaa [14]

Raising a whole number to a power means:

   Take (a number of things) a number of times, and then possibly
   take that big number of things a number of times again.

Raising a fraction to an exponent means:

   Take a piece of (a piece of one thing), and then possibly
      take just a piece of that smaller piece.

The rectangular field has a perimeter of 98 meters. The width of the perimeter is three times as much as five times the length.

White raven [17]

Answer:

a) x = 3.0625m

y = 45.9375 m

b) A = 140.68359375 m²

Step-by-step explanation:

Let x be the length

Let y be the width

2x + 2y = 98

x + y = 49

y = 3(5x)

y = 15x

x + 15x = 49

16x = 49

x = 3.0625 m

y = 15(3.0625) = 45.9375

A = xy = 3.0625(45.9375) = 140.68359375

How do I solve this question?

Sati [7]

Answer:

m=2 and n=3

Step-by-step explanation:

<u>Step</u> :-

Given $[ 2 x^{n}y^{2} ]^m = 4 x^6 y^4$

using algebraic formula $(a^m)^n= a^{mn}$

now

$2^{m} x^{mn} y^{2m} = 4x^{6} y^{4}$

now equating 'x' powers, we get

$x^{mn} = x^{6}$

$mn=6$ ....(1)

now

$y^{2m} = y^{4}$

Equating 'y' powers ,we get

2 m=4

m=2

substitute m= 2 in equation (1)

we get

2 n=6

n=3

verification:-

substitute m=2 and n=3 , we get

$[ 2 x^{n}y^{2} ]^m = 4 x^6 y^4$

$(2 x^{3} y^2)^2 = 4 x^6 y ^4\\$

$4 x^6 y^4 = 4 x^6 y^4$

both are equating so m= 2 and n=3

How to find sides of gon with meaure of each angle exterior?

MrMuchimi

All exterior angles of n-gon always add up to 360°

To find the number of sides:

$\text {Number of sides = } \dfrac{360}{\text {size of one exterior angle}}$
