Answer:

59.25 currency ; No. of cans rounded to next whole number

Step-by-step explanation:

Draw a perpendicular line frrom the 12m. line onto the 20m. line. We get a rectangle on the left and a right-triangle on the right.

Using Pythagorous theorem,

Fence = \sqrt{17^{2} - 8^{2}} m = 15 m

So, area of the lawn = ( 1/2 ) * ( 12 + 20 ) * 16 sqm = 240 sqm

So, number of cans needed = 240/100 = 2.4 ≈ 3 [Cause cans can't be partially bought ]

Total cost = 3 * 19.75 currency = 59.25 currency

( However, if cans can be partially bought, then total cost = 47.4 currency )

On this corrdinate plane UVW has been transformed to form image U’ V’ W’.
egoroff_w [7]

Answer:

C

Step-by-step explanation:

Translate the image 2 units right and 1 unit up. Then rotate the image 180°.

Take the coordinate W, it is at (2, 4).

Translate 2 units right (add 2 to the x coordinate) and 1 up (add 1 to the y coordinate)

(2, 4) ------> (2 + 2, 4 + 1) -------> (4, 5)

A rotation of 180° (doesn't matter the direction) makes the coordinates their opposites. Positives become negatives and negatives become positive.

(4, 5) -------> (-4, -5)
