Answer:

The central angle measure of the sector divided  by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector

Step-by-step explanation:

we know that

The formula to calculate the area of sector is equal to

A_s=\frac{x}{y}A_c

where

A_s ----> is the area of sector    

x ----> is the central angle measure of the sector in degrees

y  ---> total angle measure of a circle in degrees

A_c ---> represent the area of the circle

see the attached figure to better understand the problem

we have

x=m\angle ZYX=\theta^o ----> central angle of sector ZYX

y=360^o ----> total angle measure of a circle in degrees

A_c=\pi r^{2} ---> represent the area of the circle

substitute in the formula

A_s=\frac{\theta^o}{360^o} (\pi r^{2})

therefore

The central angle measure of the sector divided  by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector

The Knicks and Nets have a total 30 players.
Blababa [14]

Answer:

Step-by-step explanation:

From the problem statement, we can set up the following two equations:

K + N = 30

20K + 10N = 500

where K is the number of Knicks players, and N is the number of Nets players.

We can substitute the first equation into the second and solve for K

K + N = 30

N = 30 - K

20K + 10N = 500

20K + 10(30 - K) = 500

20K + 300 - 10K = 500

10K + 300 = 500

10K = 200

K = 20

   y - y₁ = m(x - x₁)
y - (-1) = 4[x - (-3)]
   y + 1 = 4(x + 3)
   y + 1 = 4(x) + 4(3)
   y + 1 = 4x + 12
       - 1           - 1
         y = 4x + 11

The answer is B.

5x + 6(x - 2) - 8 (x - 3)
Alex Ar [27]

Answer:

The value of x=-4. The figure is also attached below.

Step-by-step explanation:

Considering the expression

5x + 6(x - 2) - 8 (x - 3)

If we have to find the vale of x, then

5x + 6(x - 2) - 8 (x - 3)=0

5x+6x-12-8\left(x-3\right)=0

5x+6x-12-8x+24=0

3x+12=0

\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}

3x+12-12=0-12

3x=-12

\mathrm{Divide\:both\:sides\:by\:}3

\frac{3x}{3}=\frac{-12}{3}

x=-4

Therefore, the value of x=-4. The figure is also attached below.
