$\text{Hello there!}\\\\\text{We're trying to find the circumference}\\\\\text{We know that the diameter is 100}\\\\\text{We would use the equation:}\,C=2\pi r\\\\\text{The radius is half of the diameter, so the radius would be 50}\\\\\text{Plug 50 into r}\\\\C=2\pi (50)\\\\\text{Solve:}\\\\C=2\pi (50)\\\\C=2(157)\\\\C=314\\\\\large\boxed{C=314\,\,m}\\\\\text{I hope this helps!}\\\text{Best regards,}\\\text{MasterInvestor}$

circumference of circle = 2×3.14×50

circumference = 100×3.14

circumference = 314m

First off, add 3 to both sides of the equation.
6n - 3 + 3 > -18 + 3
Then, your equation should look like this: 6n > -15
Next, divide both sides by 6.
6n/6 > -15/6
Your answer is n > -5/2

there is 3/5 of pie left if 4 friends wanted to share the pie equally how much pie would each friend receive/7095668/7abc4acb?ut

Serjik [45]

You would divide 3/5 by 4/1 so then that would mean you keep change flip so its 3/5 times 1/4 which is equal to 3/20 each person or friend would get

Use the pythagoren theorem to solve x

defon

Well the equation is (A^2)+(B^2)=(C^2)

A= x
B= 2x
C will always be the longest side because it is the Hypotenuse = 25

So if you plug in those numbers into the equation...

(x^2) + (2x^2) = (25^2)

x^2 + 4x^2 = 625

Combine like terms

5x^2 = 625

Divide by five to both sides

x^2 = 125

Then Square root,

x = sqrt(125)

x = sqrt(25* 5)

x = 5sqrt(5)

What is the answer and how do you solve <br><br><br> 21x^3/3x^−1

Sunny_sXe [5.5K]

Answer:

as written: 7x^2

perhaps intended: 7x^4

Step-by-step explanation:

As written, the Order of Operations specifies that the only denominator factor is 3, so the expression is interpreted as ...

$\dfrac{21x^3}{3}x^{-1}=\dfrac{21}{3}x^{3-1}=7x^2$

___

Sometimes grouping of denominator factors is intended, but parentheses are not written as they should be. If the intention is ...

21x^3/(3x^-1)

then the simplification is ...

$\dfrac{21x^3}{3x^{-1}}=\dfrac{21}{3}x^{3-(-1)}=7x^4$

_____

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^b/a^c = a^(b-c)
