Answer:

160.57

Step-by-step explanation:

The formula is:

$angle/360 *\pi *radius^2$

Because you find the total area of the circle, but the sector only represents NPQ/360 so you have to multiply the area with that.

$46/360 * \pi *20^2$ = $23/180 * \pi *400$

= $160.57029...$

Rounded to the nearest hundredth this would be 160.57

If T(x, y) = (x + 5, y + 6) and Pris the image of P, what is the rule for the translation in which P is the image of P'? T(x, y)

xxTIMURxx [149]

Answer:

The translation is;

$T(x,y)=(x-5,y-6)$

Explanation:

Given the translation rule;

$T(x,y)=(x+5,y+6)$

when P' is the image of P.

For the inverse, when P is the image of P', the Translation rule would become;

$\begin{gathered} x=x^{\prime}+5 \\ x^{\prime}=x-5 \\ y=y^{\prime}+6 \\ y^{\prime}=y-6 \\ So,\text{ the translation rule becomes;} \\ T(x,y)=(x-5,y-6) \end{gathered}$

The translation is;

$T(x,y)=(x-5,y-6)$

FOR 20 points

DochEvi [55]

Answer:

one tin of cheese $23

one tin of caramel $27

Step-by-step explanation:

let 'x' = cost of cheese tin

let 'y' = cost of caramel tin

10x + 8y = 446

22x + 11y = 803

i multiplied the first equation by -11 and the second by 8 to eliminate the 'y' terms

-110x - 88y = -4906

+ <u>176x + 88y = 6424</u>

66x = 1518

x = 1518 / 66

x = 23

find 'y': 10(23) + 8y = 446

230 + 8y = 446

8y = 216

y = 27
