Answer:

No

Step-by-step explanation:

First, figure out the circumference:

c=\pid

c=\pi180=565.48

Then divide by the space needed:

565.48÷70=8.07

With 18 tables and 8 people per table:

18x8=144

So they only have seating for 144 guests.

19 is 6% of what number?
Lilit [14]
You have to be able to take the words written down and put them into mathematical symbols.  The word "is" means =, the word "of" means to multiply, "what number" is x, your unknown.  So translating that from words to an equation looks like this: 19 = .06x.  Divide both sides by .06 to get x = 316 2/3

Need help on this math problem!!!
Colt1911 [192]

Answer:

(fof^{-1})(x)=x

Step-by-step explanation:

Composition of two functions f(x) and g(x) is represented by,

(fog)(x) = f[g(x)]

If a function is,

f(x) = (-6x - 8)² [where x ≤ -\frac{8}{6}]

Another function is the inverse of f(x),

f^{-1}(x)=-\frac{\sqrt{x}+8}{6}

Now composite function of these functions will be,

(fof^{-1})(x)=f[f^{-1}(x)]

                  = [-6(\frac{\sqrt{x}+8}{6})-8]^{2}

                  = [-\sqrt{x}+8-8]^2

                  = (-\sqrt{x})^2

                  = x

Therefore, (fof^{-1})(x)=x
