ANSWER

( {x - 11)}^{2}  + ( {y - 5)}^{2}  = 16

EXPLANATION

The given circle has center:

(11,5)

and

radius: 4

The equation of a circle with center (h,k) and radius , r is given in standard form as;

( {x - h)}^{2}  + ( {y - k)}^{2}  =  {r}^{2}

We substitute the values into the formula to obtain,

( {x - 11)}^{2}  + ( {y - 5)}^{2}  =  {4}^{2}

( {x - 11)}^{2}  + ( {y - 5)}^{2}  = 16

Westkost [7]

Answer:

The expression for the average number of tickets sold per school child is:

M = \frac{tickets*class1 + tickets2*class2 + tickets3*class3}{class1 + class2 + class3}

Step-by-step explanation:

The average number of tickets sold per school child is the weighted mean calculus between the number of tickets sold by these classes and the number of children in each classes.

This is the multiplication between the number of tickets sold by these classes and the number of children in each classes divided by the total weight(in this exercise, the total weight is the total number of school child).

So, the expression for the average number of tickets sold per school child is:

M = \frac{tickets*class1 + tickets2*class2 + tickets3*class3}{class1 + class2 + class3}

BRO SOMEONE PLEASE HELP ME OUT BRO I FR NEED SOME HELP. HOW DO YOU DO THIS
Finger [1]

Answer:

there you go bro. 168 degrees   for each angle

Step-by-step explanation:

To calculate the central angle visualize a circle in the center of the polygon. A circle has 360 degrees. Divide 360 by the number of sides and that will tell you the central angle size. So 360 divided by 30 equals 18 degrees.

To find the base angle use this formula

180(n-2)/n where n is the number of sides of a regular polygon.

When you plug in 30 for n

vazorg [7]

Answer:

\frac{1}{3}  +  \frac{1}{4}

Step-by-step explanation:

We want to find an expression that has a value of

\frac{7}{12}

First option:

\frac{7}{8}  + 4 =  \frac{7}{8}  +  \frac{32}{8}  =  \frac{39}{8}  \ne \frac{7}{12}

Second option:

\frac{1}{3}  +  \frac{1}{4}  =  \frac{4}{12}  +  \frac{3}{12}  =  \frac{7}{12}

Correct option

Third option

\frac{6}{8}  +  \frac{1}{4}  =  \frac{3}{4}  +  \frac{1}{4}  = 1

Fourth option:

2 \frac{1}{12}  + 5 \frac{1}{12}  =  \frac{43}{6}
