Help with this show work plz explain<br><br> Answer should be<br><br> A=. Cm squared
elixir [45]
The shaded region is actually a sector and the formula for the area of a sector is:
central angle/360 x pi x radius squared, which is basically a fraction of the area of the circle. With this basic background knowledge, all we have to do is substitute the values into the formula.

(80/36) x pi x 81
= 80/4 x pi x 9
= 720/4 x pi
= 180pi cm squared.

Find the value of (64/25)^-1/2 Give your answer as fraction in its simplest form.​
Elis [28]

Answer:

\frac{5}{8}

Step-by-step explanation:

(\frac{64}{25})^{-\frac{1}{2} } has a negative, fractional indice; this negative sign in this context means to make the base fraction a reciprocal (flip it!):

(\frac{25}{64})^{\frac{1}{2}} The denominator is the value by which we should root, then the numerator is the power the fraction should be raised to: [root and then raise]

\frac{(\sqrt{25})^{1}  }{(\sqrt{64})^{1}  } This fraction then becomes:

\frac{5}{8}

-5x + y = -2, -3x + 6y= -12. Solve each system by substitution
Ahat [919]

Answer: x = 0, and y = -2

Step-by-step explanation:

-5x + y = -2 .........(1)

-3x + 6y = -12 ......(2)

From equation (1)

-5x +y = -2 .........(1)

y = 5x - 2 .............(3)

Now substitute for y  in equation (2)

-3x + 6 (5x -2 ) = -12

Make use of 6 to open the bracket ,we now have

-3x + 30x - 12 = -12

= 27x - 12 = -12

Collect the like terms

27x = -12 + 12

27x = 0

Divide through by 27 to get the value of x

x = 0/27

x = 0

To determine y, substitute for x in equation (3)

y = 5x - 2

y = 5(0) - 2

y = 0 - 2

y = -2

Check : Substitute for x and y in equation (1)

-5x + y = -2

-5(0) + (-2) = -2

0 -2 = -2

0 - 2 = -2
