Answer:

  16.4

Step-by-step explanation:

The law of cosines is useful here. It tells you ...

  b^2 = a^2 + c^2 -2ac·cos(B)

  b^2 = 22^2 +10^2 -2·22·10·cos(44°)

  b^2 ≈ 267.49

  b ≈ √267.49 ≈ 16.35514

  b ≈ 16.4

a ticket office sold 553 tickets one day. the receipts totaled $3936. how many $9 adult tickets and how many $6 child tickets we
Vsevolod [243]

This is the assumption method ;)

Take all tickets to be adult tickets

$9 x 553 = $4977

Then..... $4977 - $3936 = $1041

The difference between the child and adult ticket is $3, so divide $1041 by $3

$1041 divided by $3 = 347

347 is the number of <em>child </em>tickets sold

347 x $6 = $2082

So 553 - 347 = 206 ( no. of adult tickets )

206 x $9 = $1854

Child tickets sold : 347

Adult tickets sold : 206

Answer:

6 inches

Step-by-step explanation:

Formula for surface area of a cylinder:

SA=2\pi r^{2} +2\pi rh

Plug in values and solve for the radius:

180\pi =2\pi r^{2} +2\pi r(9)\\

Divide both sides by 2\pi

90=r^{2} +r(9)

Subtract 90 from both sides

0=r^{2} +9r-90

Use the quadratic equation to find the roots

x=(-b±\sqrt{b^2-4ac})*\frac{1}{2a} (sorry for formatting, Brainly doesn't

                                           allow equations with ± in them)

x=\frac{-9+\sqrt{9^2-4*1*90} }{2(1)}        and          x=\frac{-9-\sqrt{9^2-4*1*90} }{2(1)}

x=\frac{(-9+\sqrt{81+360})}{2}          and          x=\frac{(-9-\sqrt{81+360})}{2}

x=\frac{(-9+\sqrt{441})}{2}               and          x=\frac{(-9-\sqrt{441})}{2}

x=\frac{(-9+21)}{2}                   and          x=\frac{(-9-21)}{2}

x=\frac{12}{2}                           and          x=\frac{-30}{2}

x=6                             and          x=-15  

We can't have a negative radius, so that leaves us with r=6 in.
